Darwin-L Message Log 8: 1–30 — April 1994
Academic Discussion on the History and Theory of the Historical Sciences
Darwin-L was an international discussion group on the history and theory of the historical sciences, active from 1993–1997. Darwin-L was established to promote the reintegration of a range of fields all of which are concerned with reconstructing the past from evidence in the present, and to encourage communication among scholars, scientists, and researchers in these fields. The group had more than 600 members from 35 countries, and produced a consistently high level of discussion over its several years of operation. Darwin-L was not restricted to evolutionary biology nor to the work of Charles Darwin, but instead addressed the entire range of historical sciences from an explicitly comparative perspective, including evolutionary biology, historical linguistics, textual transmission and stemmatics, historical geology, systematics and phylogeny, archeology, paleontology, cosmology, historical geography, historical anthropology, and related “palaetiological” fields.

On the first of every month I send out a short note on the status of our group with a reminder of basic commands. Darwin-L is seven months old, and we have more than 550 members from about 30 countries. I am grateful to all of you for your interest and your many contributions. The Darwin-L gopher archive is open to all subscribers on rjohara.uncg.edu (numeric address 152.13.44.19); it contains the logs of our past discussions, several bibliographies of interest to historical scientists, and gateways to a variety of other interesting network resources. Pay a visit and bring your friends. A recent addition to the Darwin-L gopher archive is Geoff Read's list of natural history book dealers. The following are the most frequently used listserv commands that Darwin-L members may wish to know. All of these commands should be sent as regular e-mail messages to the listserv address (listserv@ukanaix.cc.ukans.edu), not to the address of the group as a whole (Darwin-L@ukanaix.cc.ukans.edu). In each case leave the subject line of the message blank and include no extraneous text, as the command will be read and processed by the listserv program rather than by a person. To join the group send the message: SUBSCRIBE DARWIN-L <Your Name> For example: SUBSCRIBE DARWIN-L John Smith To cancel your subscription send the message: UNSUBSCRIBE DARWIN-L If you feel burdened by the volume of mail you receive from Darwin-L you may instruct the listserv program to deliver mail to you in digest format (one message per day consisting of the whole day's posts bundled together). To receive your mail in digest format send the message: SET DARWIN-L MAIL DIGEST To change your subscription from digest format back to one-at-a-time delivery send the message: SET DARWIN-L MAIL ACK To temporarily suspend mail delivery (when you go on vacation, for example) send the message: SET DARWIN-L MAIL POSTPONE To resume regular delivery send either the DIGEST or ACK messages above. For a comprehensive introduction to Darwin-L with notes on our scope and on network etiquette, and a summary of all available commands, send the message: INFO DARWIN-L To post a public message to the group as a whole simply send it as regular e-mail to the group's address (Darwin-L@ukanaix.cc.ukans.edu).

O'Hara (darwin@iris.uncg.edu) answered > have come around to the view that Greg Mayer has expressed here once or >twice (he taught me everything I know), that we should take the terms >cladistic" and "phenetic" to refer to intentions rather than particular >procedures, types of data, or algorithms.

But the fact that they may be poor estimates in some cases >does not, in my view, make them non-cladistic. I am going to have to respectfully disagree. If intentions are all that is required for a technique to be cladistic, then much of the post acceptance of Darwin (Charles, that is) systematic work is cladistic. At least this would be the case in vertebrate paleontology (my field). The goal and purpose of much of the research has been to reconstruct the phylogeny of organisms. However, I would be hard-pressed to describe the gestalt based hypotheses of relationships popular in the nineteenth and early twentieth century as cladistic. (This is not to say that the proposed relationships were necessarily incorrect, only that the basis for the phylogenies were not explicitly stated.) Instead, I would say that cladistic refers to a procedure rather than an intention. I think that there is a feature necessary and sufficient for a method to be considered cladistic (the synapomorphy of cladistic methods, if you will). This feature is that cladistic methods must make an explicit evaluation of whether features shared by organisms are uniquely shared or part of a primitive suite of features. In jargon -- the explicit rejection of plesiomorphic characters in the evaluation of phylogeny. While I'm at it I should probably introduce myself. I am a vertebrate paleontologist at the Illinois State Museum. I work as a post-doctoral research associate studying the changes in small mammal faunas over the last 200,000 years and what these changes tell us about changing environmental and climatic conditions.

Born in Germany in 1687, Dillenius studied medicine at Giessen and was eventually appointed doctor to the town. His interest in botany won him election to the Caesare Leopoldina-Carolina Academia Naturae Curiosum, and he soon published a flora of the region around Giessen, _Catalogus plantarum circa Gissam sponte nascentium_ (Frankfurt am Main, 1718). Because Dillenius was critical of Bachmann, whose botanical system was then popular, he did not find favor in German systematic circles, and he emigrated to England in 1721 at the invitation of William Sherard, who hired Dillenius to work on his botanical encyclopedia. In England Dillenius was elected a fellow of the Royal Society, and in 1724 he oversaw the publication of the final edition of John Ray's _Synopsis plantarum_ (London, 1724). He played host to Linnaeus in 1736 when the Swedish botanist visited Oxford, and published _Historia muscorum_, an influential study of the cryptogams, in 1741. His herbarium will be preserved in the collections of Oxford University.

Toomey writes: >I am going to have to respectfully disagree. If intentions are all that is >required for a technique to be cladistic, then much of the post >acceptance of Darwin (Charles, that is) systematic work is cladistic. >At least this would be the case in vertebrate paleontology (my field). >The goal and purpose of much of the research has been to reconstruct >the phylogeny of organisms.

This feature is that cladistic methods must make >an explicit evaluation of whether features shared by organisms are >uniquely shared or part of a primitive suite of features. In jargon -- the >explicit rejection of plesiomorphic characters in the evaluation >of phylogeny. Myself, I think there are three elements that are essentially cladistic. The first is an idea are about the goals of systematics: that its sole aim, as Bob has once put it, is "telling the tree". Of course I agree with Toomey that one of the aims of taxonomy since Darwin has been to reconstruct evolutionary history, but that aim has been mixed up with all sorts of other issues; for example about the degree and kinds of divergence necessary to warrant a valid use of higher taxonomic categories. I take it that one of the basic lessons of cladism is that, for example, the various debates about when in human evolution true hominids appeared are wastes of time. I realize that many pre-cladistic systematicists were somewhat sceptical about the status of higher taxonomic units, but in my view its the cladists who really rammed this home. The second is the methodological idea that Toomey I think is right to emphasize: that characters that are primative to a group can tell you nothing about relations within that group. Third, I think there is a metaphysical idea: that only monophyletic chunks of the tree are biologically real entities. I doubt whether all this has to be a package deal; in particular, one could clearly accept the methodological moral about the reconstruction of history whilst accepting the biological reality of some non-monophyletic chunks of that tree.

The son of a lawyer and public official, the young Catesby will develop an early interest in botany and will become a friend of the prominent English naturalist John Ray. From 1712 to 1719 Catesby will live with his sister in the Virginia colony, and the plants he will collect during his stay in America will bring him to the attention of a number of other prominent naturalists, including Sir Hans Sloane. Catesby will be commissioned to return to America for the purpose of natural history exploration and collecting, and from 1722 to 1726 he will travel through South Carolina, Florida, and the West Indies. Upon his return to England he will publish the acclaimed _Natural History of Carolina, Florida, and the Bahama Islands_ (1731-1743), a work that will be used by Linnaeus as the source for his descriptions of North American birds.

I had said that intention is what makes a technique cladistic, rather than the particular type of data used, etc. Let's see what I can make of the question now. First I take it that we are agreed on Paul DeBenedictis's first question, that distance data can be used to estimate phylogeny. In any particular case it may be a good way or a bad way to estimate phylogeny, but it is a way. The question at issue is his other one: "What makes a technique cladistic?" This of course is a matter of definition, but it is interesting to consider nontheless. <-- (Note clever deployment of classic rhetorical strategy: "OK, so maybe I am wrong, but it doesn't really matter that much anyway.") ;-) One thing I failed to do in my original answer was distinguish between present-day prescription and historical description (shame on me), and that is what Rick and Kim both picked up on. Paul had asked his question in the specific context of a review of a modern work, and I was trying to make the point that it didn't really matter whether the author was using distance data or character data: what he was trying to do was make trees, and hence he was doing something cladistic. Rick and Kim point out that there were people making trees ever since the _Origin_ and that it doesn't seem right to say that they were all doing cladistics. There certainly were, and no, it doesn't seem right to call their work cladistic. I find myself wanting to distinguish between "phylogeneitc" and "cladistic" now, however. Many systematists since the late 19th century have tried to reconstruct phylogeny. (As Kim points out, though, they often had other interests mixed in with that activity in a somewhat confused manner from the modern standpoint.) If I say that "cladistic analysis" is a particular method of reconstructing phylogeny, then maybe Rick and Kim will be satisfied -- it would be that method of reconstructing phylogeny which is based on the idea that only innovations (derived character states) can be used to identify clades, and that a "character" is a difference among taxa from which we infer an evolutionary event, the states of the character being the different "sides" of the event (before and after). Under this definition, "cladistics" is reduced to more or less traditional (Hennigian) character-based studies of the sort that really didn't exist much before the 1950s or '60s. But the enterprise of (non-cladistic) phylogenetic reconstruction goes back much farther. Modern distance methods of phylogenetic reconstruction would thus be "phylogenetic" but not "cladistic". (For our next lesson I will explain the difference between "tomato" and "tomato".) I'm sure the eyes of all the non-systematists are starting to glaze over at this point. These disputes about shades of meaning of technical terms can look very odd from the outside, I know. This discussion is a bit like the discussion we were having a while ago on the word "structuralism", though. In linguistics we might ask what makes a technique "structuralist" (as I did a while ago, and Sally Thomason replied very helpfully), or "typological" or "historical". "Typology" is another word that is used in both linguistics and systematics; in linguistics it is a legitimate mode of inquiry (so I understand), but in systematics "typology" usually considered a term of abuse ("he is a typologist" is kind of like saying "he is a communist"). An excellent book came out a couple years ago: _Keywords in Evolutionary Biology_, edited by Evelyn Fox Keller and Elisabeth Lloyd (Cambridge: Harvard University Press). It is a collection of chapters devoted to terms like "selection", "fitness", species", etc. Glancing at my copy I see chapters by _four_ Darwin-L members: Richard Burian on "Adaptation", Robert Brandon on "Environment", Michael Donoghue on "Homology", and Peter Stevens on "Species". (We are in very good company here.) Perhaps an expanded version of the book or another similar collection of chapters could be made that would extend beyond evolutionary biology to key terms used in all the historical sciences.

Bob O'Hara (darwin@iris.uncg.edu) --------------------------------------- Bob O'Hara suspects that the eyes of us non-systematists will be glazing over at the discussion of what is & isn't cladistics, and why: not so, at least for this non-systematist -- I'm finding this discussion really educational, and if I keep reading long enough I might actually understand what's going on in that area. Understanding the biological systematists is crucial for figuring out the relationships between the tree-building enterprises in biology and linguistics (and elsewhere), after all. Bob's revised definition of cladistic analysis -- the method based on the idea that only innovations count in identifying clades -- is THE obvious link between systematics and historical linguistics: shared innovations has always ("always" = since the late decades of the 19th century, when the comparative method got into high gear) been the primary criterion for subgrouping languages in a family tree. (And since the comparative method, which most of us believe is the only tried & true method for establishing language families, hasn't been shown to be valid for time depths anywhere near the presumed origin of human language, our numerous language families are each, for all practical purposes, the equivalent of the systematists' single tree.) A brief comment on Bob's mention of the different connotations of typology in linguistics and systematics (and apologies if this repeats comments made in earlier discussions of typology): typology is absolutely respectable in linguistics, but NOT as a historical methodology. It is in a synchronic field of study that seeks to identify common, not so common, and nonexistent structural patterns in languages of the world, with a view toward understanding the functionally and/or genetically determined (or at least influenced) properties of human language. It's true that typological arguments have been brought to bear, by a number of scholars, on the question of what to reconstruct, for a parent language, from the patterns found in a bunch of daughter languages. One line of argumentation (maybe the main line) goes like this: (almost) no language in the world has pattern X; therefore, we cannot reconstruct pattern X for the ancestor of these languages. Arguments of this strong type are highly controversial and have not been generally accepted. The best- known instance, probably, is the Glottalic Theory, a typological proposal for the reconstruction of Proto-Indo-European stops. But in a weaker form, typology IS used by all of us in reconstructing bits of proto- languages: when, for instance, you have two sounds that correspond regularly in the only two daughter languages of a family -- say, h and p -- and you have to make a guess about which (if either) of these two sounds represents the parent language's sound...or, more precisely, phoneme...you guess the p, essentially on typological grounds: we all know of quite a few sound changes of the type *p > h, but we know of few or no changes of the type *h > p; since, therefore, *p > h seems a more likely change, we reconstruct *p for the proto-language's phoneme. [Some historical linguist who is more knowledgeable than I am will promptly post fifteen examples of sound changes from *h to p! So I'll respond to that posting now: the methodological point is valid, even if the particular example is no good. Pretty weak answer, eh? But I think most historical linguists would agree with it.] Notice, though, that using typology in this way in reconstructing proto-languages has nothing to do with establishing language families. Probably no current historical linguist would argue that shared structural features in themselves provide evidence for language-family grouping.

I have a graduate student, Randy Jackson, working on the history of fish systematics, in particular comparing the work of Cope, Gill, and Guenther. He tells me that the system developed by Gill in 1871 uses principles or technique that we would today call cladistic. Of course, seeing an identity of ideas is fraught with difficulty. As a historian, it does not surprise me that we would find, in an earlier period, various pieces of a later research program. We should resist the temptation of having to see everything in the invention of cladistics as radically new. However, the hunt for piecemeal "precursors" of an idea is very out of fashion, for good reason, in the history of science. Recognizing that Gill is working within the problems and assumptions of the 1870s, Randy is trying to determine how/if each taxonomist's reaction to evolutionism affects the system he produces. If any List members who are conversant in fish systematics and/or the history of systematics would be willing to provide comments on his work, please let me know.

Now, this is real wrist-slashing stuff! Like most biologists, I have girded loins to face each day in the belief, beaten into us with the tablets of stone they are engraved on, that a) phylogeny and phylogenetic relationships are important for some reason, and b) reconstructon of a believable chain of events is ultimately possible. Thus we are able to suppress the overwhelming desire to put all the reds ones in one heap and blue ones in another and divide each heap into big ones and little ones just because such a classification easy to understand... > Isn't this trail even more dubious > in language and other cultural or behavioral studies?

I've been avoiding using our standard term, which is "genetic relationship", for fear of confusing and/or annoying people who deal with literal rather than metaphorical genes. Anyway, the concept of a language family is pretty clear, although -- not surprisingly -- it's fuzzy around the edges: if one language diverges over time into two or more daughter languages, that's a language family. The daughter languages are changed later forms of their single parent language. There are some methodological assumptions which, though clearly invalid most of the time in real life, are useful nevertheless; the major one is that, when a lg. splits into two or more daughters, the split is CLEAN: that is, no more contact between the daughters after the split. You don't get a split at all unless there's some breakdown/reduction in communication between speakers of two or more dialects; but cases like Romani, whose speakers had no more contact at all with other Indic languages after they left India in ?1500 A.D.?, are pretty rare, as far as we know. At shallow enough time depths, when there's still a lot of evidence left (not too many changes in the daughter languages to obscure the regularities of descendent lexical and grammatical features), it's fairly easy to separate inherited material from borrowed material (i.e. convergences), IFF the borrowing isn't occurring between very closely related languages. But that's at shallow enough time depths. Once you're several thousand years away from the source, things get more difficult; that's why historical linguists make an informal guess of ca. 10,000 years as the upper limit for establishing genetic relationships among languages. (Most historical linguists, anyway.) After that too many changes have left so few systematic traces that it can be impossible to distinguish borrowed from inherited features, even when you're pretty sure that there is SOME historical connection between two or more languages. So historical linguists don't expect ever to construct a family tree for ALL human languages, assuming that there was once one single original language; we have some hundreds of language families currently, and though that number will undoubtedly shrink as the laborious historical study of different groups progresses, it's unlikely to shrink to just a few huge language families -- not at the time depths that, to judge by the level of diversity in the world's several thousand languages, must be reckoned with. Language is significantly different from other cultural or behavioral studies, though: language change is largely, though not entirely, independent of speakers' or societies' desires and intentions; language changes willy-nilly, which is why (for instance) pundits who rail against the sloppiness of, say, modern English speakers have been thriving for hundreds of years. There are fads in language, to be sure (like teen-age slang), but they are quite superficial: the structure of the language tends not to be affected by fads. Other cultural and behavioral studies have nothing like the regularity hypothesis of sound change, which is our main means of tracing language history back through time.

If someone wants to (or has) tried it, post a response. The goal is to get a mass comparison of two languages without being bogged down by grammar, vocabulary and phonetics. That's not quite possible, because without some consideration you'll be comparing arbitrary segments of human speech. In biology, physical chemistry takes care of aligning "same" thing in different organisms, and we need a linguistic equivalent to physical chemistry. So here's the proposal. First, construct a lot of simple sentences (child speech) that talk about fairly universal things - environmental constants like night, day, sun, rain, clouds; human constants - basic anatomy, gender, physiology; social constants - biological family relationships, generic activities like singing and talking, and whatever else you decide. Part of the experiment will be to decide how much you need. Examples: Two men are sleeping. I am thirsty. My mother gives me drink. His wife is singing. Second, you need to record (in a constant voice and rate) each of the sentences in a fixed order. It might be helpful to use a computer to generate the records, to minimize variation due to voice and timing. Third, now do spectral correlations between the different recordings. The correlation coefficients are the distance values. A correlation between phonemes might also do the job without the requirement for constant voice and rate, if you can devise an a priori value to measure the differnce between phonemes. And decide on a "universal" system of phonemes (hope this is the right word - I mean a basic unit of sound in speech). Note that this proposal detects two types of change without distinguishing between them - phoneme shifts and grammar shifts. But it does yeild a mass comparison. An interesting subquestion would be - how extensive should the sentence list be to give meaningful results. If I were doing this, I'd start with something like Romance languages and if it produces anything reasonable, see how different things have to be before it "blows up" if it ever does. But I'm not a linguist, so the idea is free for anyone who wants to give a try (if it's great, I'd appreaciate at least partial credit - if it's a disaster, forget I had anything to do with it).

Let's see, with just one utterance, in three Romance languages, 'I'm hungry'. Fr. J'ai faim. It. Ho fame. Sp. Tengo hambre. We record these in speech, and they come out (blessed ASCII! -- excuse the fake phonetic alphabet): [zhefe~] [ofame] [tengoambre] I'm not sure how your proposal would proceed at this point. Traditional analysis (pretending no a priori knowledge) might go something like this: it would catch that the first syllable in Fr. and It. is different, and that it seems to correspond to two (unrelated) syllables in Sp. Then we'd work to sort out what's going on in those cases, and it would fall out that we have three distinct forms of 'I have', and that French uses the subject pronoun. Depending on the type of analysis, we may continue, to figure out that the 'have' of Fr. and It. are historically related, and Sp. 'have' is another item altogether. Or we may jump to the syllables following 'have', and find that to Fr. and It. [f] corresponds Sp. null (I'm thinking in Romance and the syntax shows it; sorry!), and that all three then have vowel + [m] (or in French, nasalization suggesting something m-ish). Somehow we'd have to account for French ending with a (remnant of) /m/, but Italian having [e] following it, and Sp. with a mouthful, [bre]. Synchronic analysis wouldn't take us much further than finding that It. and Sp. disfavor (some would claim, don't allow) final [m], but an historical examination would eventually reveal that the two variants [fe~], [fame] are derivable from the same proto-form by regular sound change evinced in other words, and that Sp. fits into this except for the [bre] part. If we're looking for "family" relationships, we could say, then, that the 'hunger' word is either a very early borrowing (early enough to have been run through all the expected historical changes of each language), or it's a form inherited in all three from the "mother" language. If we assume that the mother is Latin, we will, in fact, find what looks like [fame] there, confirming the commonly inherited origin. (Further work would show that Sp. [bre] requires a source [famine], but enough; I fear eyes are glazing as I write!) Can you say how your suggestion is different from this?

I have only ever described and named two subspecies (names witheld to protect the innocent) in my life and they have not been collected, mentioned, looked at or even thought about by the biological or general community in the decade and a half since the protologue was smeared on wood pulp. Such is the impact of science, but it seemed important at the time... What does the propensity for anything to hybridize mean? In our gardens (with over 30% of the Australian vascular flora in cultivation) we have all manner of indecent and unnatural acts going on with things hybridizing all over the place, events that would never happen in nature because the taxa would never come into contact with other. It is because we can not trust the parentage of seeds in the gardens that we do not produce a seed list or repropagate from our own seeds if at all avoidable. The catch-cry 'but they hybridize' is often used to cast doubt and aspersion on the distinction of two taxa, but should it? There are taxa here that are morphologically virtually indistinguishable, have similar habitat requirements but produce pheremones that attract a particular species of insect pollinator and their gene pools are totally isolated - any sane person would give them the same name and put them in the same folder in the herbarium - but should they? For Iain, the following is serious %^| These days I am not game to recognize the genus _Eucalyptus_, let alone talk about species, subspecies and hybrids.

He tells me that the system developed by Gill in 1871 uses >principles or technique that we would today call cladistic. I don't know Gill's work (great name for an ichthyologist, ay?), but the claim is plausible. In my experience, however, one must be very careful in making such judgments about past systematists. Arthur Garrod, for example, a nineteenth-century ornithological systematist, published a diagram that looks an awful lot like a modern cladogram, but when you study his text carefully you can see that it is not. He was, however, trying to figure out how one should go about reconstructing trees, and made many interesting theoretical proposals. The earliest work that I have seen which I would be comfortable calling cladistic in the modern sense (i.e., one that recognizes clearly the distinction between ancestral and derived character states, and recognizes that only derived character states [innovations] identify clades) is that of Peter Chalmers Mitchell around 1900. If there are other such works I would be most interested to hear about them. One highly recommended paper is: Craw, Robin. 1992. Margins of cladistics: identity, difference and place in the emergence of phylogenetic systematics, 1864-1975. Pp. 65-107 in: Trees of Life: Essays in Philosophy of Biology (Paul Griffiths, ed.).

As a young man Bartram will accompany his father on his botanical travels through the Catskill Mountains and Connecticut in the early 1750s, and he will become a skillful natural history illustrator. His drawings will be sent to Peter Collinson in London, the elder Bartram's scientific patron, and Collinson and the British naturalist George Edwards will commission Bartram to produce some of the illustrations for Edwards's _Gleanings of Natural History_. After a series of unsuccessful business ventures, the elder and younger Bartrams will travel to Florida in 1765, and William will remain there to try his hand, unsuccessfully again, at farming. A new London patron, the physician John Fothergill, will offer to support Bartram on a collecting expedition across southeastern America, and the report of this trip, _Travels Through North & South Carolina, Georgia, East & West Florida, the Cherokee Counntry, the Extensive Territories of the Muscogluges or Creek Confederacy, and the Country of the Chactaws_ (Philadelphia, 1791), will be soon reprinted in London and translated into French, German, and Dutch, and will win Bartram fame throughout Europe. Bartram's vivid and graceful descriptions of American natural history in the _Travels_, as well as his accounts of the native peoples of the region, will influence the European Romantic writers of the early 1800s, and he will act as a teacher to a whole generation of American naturalists including Thomas Nuttall, Thomas Say, and Alexander Wilson.

For my money the freshest clarification in many years to the age-old problem of defining species is the recent article by our list-owner, Bob O'Hara - but I don't have my reprint at hand. Robert, please don't be so modest, but give everyone the citation. The effect of understanding evolution is not to provide a final definition of taxonomic categories, including the particularly important category around the gene-pool level, but to make it obvious why a certain percentage of cases will always be elusive and require artificial (but not arbitrary) lines to be drawn. Dr. O'Hara provides and detailed and helpful analogy to the problem of detail resolution in cartography, plus explaining how events that lie in the future as well as past phylogeny are built into the problem. Too much of previous discussions has called upon the authority of formal philosophy, for my money, whereas O'Hara's analysis is practical and realistic. The result, of course, is not a neat formula or criterion, but understanding of the nature of the problem. When Darwin said the result of his theory would be an end to the endless disputes over whether this or that was in essence as true species, he didn't mean the disputants would have a key to the right answer in every case, but that they would see that the concept of "essence" was crazy.

The most quoted instance is probably from the _Introductory Lectures to Psychoanalysis_ (1917), when Freud locates himself in a line of descent from Copernicus to Darwin. A more theoretical link is contained in _Totem and Taboo_, where Freud draws on Darwin's hypothesis of the primal horde. In a letter to Jung (14/5/1912), Freud writes: Many authors regard a primordial state of promiscuity as highly unlikely. I myself, in all modesty, favour a different hypothesis in regard to the primordial period -- Darwin's. I presume this is the idea of the horde lead by a dominant male who expelled rivalrous males, thus enforcing a kind of exogamy. Freud, of course, proposed a second stage when the expelled sons return to kill the leader/father. I am curious to know how seriously Freud's participation in this argument have been taken within the Darwinist tradition. Were there any Darwinists who agreed with Freud's own positioning as the successor to Dawrin?

May I suggest that there may be some other reasons for plants not being included in paleontology. I am trained as a paleobotanist, but much of my work in studying coal involves geology. I have been fascinated by the different perspective different disciplines take. It is my impression that geologists often look at fossils more as useful or non-useful objects for biostratigraphy. Although they know they were creatures they often don't often look at them from a biotic perspective. Since in most marine environments the hard shelled invertebrates (trilobites, brachiopods etc. are usually more abundant and better preserved, their is a tendency not to think of the plants (algae) which usually are not well preserved. I still remember sitting in on a geology paleoecolgy class in the geology department. The professor was going into all the animal relations, but had not even thought of the base of the food chain (the algae), until another paleobotanist and I asked about it. At that University (U. of Illinois) paleobotany was studied in the Botany not Geology department and even though it was cross listed with geology, we did not have many geologists taking the course. I am well aware that there is an increasing trend toward understanding ecology and the biology of the fossils in geology, but I still think some of the attitude of looking at fossils as objects for biostratigraphy affects geology. Except for palynology, and some algae microfossils, the major place I recall plants getting used for biostratigraphy is European Carboniferous. In other words plants are generally less useful for biostratigraphy and geologists are more apt to be focusing on organisms as biostratigraphic object then their biotic side. Hence it is not really surprising to find plants neglected. It does not help that many geology departments have moved toward hard rock geology (which is not the best environment for any fossil preservation), but that is another story. James F.

O'Hara, R. J. 1993. Systematic generalization, historical fate, and the species problem. _Systematic Biology_, 42:231-246, 1993 The species problem is one of the oldest controversies in natural history. Its persistence suggests that it is something more than a problem of fact or definition. Considerable light is shed on the species problem when it is viewed as a problem in the representation of the natural system (sensu Griffiths, 1974, Acta Biotheor. 23:85-131; de Queiroz, 1988, Philos. Sci. 55:238-259). Just as maps are representations of the earth and are subject to what is called cartographic generalization, so diagrams of the natural system (evolutionary trees) are representations of the evolutionary chronicle and are subject to a temporal version of cartographic generalization, which may be termed systematic generalization. Cartographic generalization is based on judgements of geographical importance, and systematic generalization is based on judgements of historical importance, judgements expressed in narrative sentences (sensu Danto, 1985, Narration and knowledge, Columbia Univ. Press, New York). At higher systematic levels, these narrative sentences are conventional and retrospective, but near the species level they become prospective, that is, dependent upon expectations of the future. The truth of prospective narrative sentences is logically indeterminable in the present, and since all the common species concepts depend upon prospective narration, it is impossible for any of them to be applied with precision. I was also following Jim and Iain's comments on species as Polly was, and thought it might be of interest to note the possibly different traditional practices or perspectives of systematists who work on different taxa. For example, Jim Croft, in speaking of some of the inhabitants of his gardens, commented: >There are taxa here that are morphologically virtually indistinguishable, >have similar habitat requirements but produce pheremones that attract a >particular species of insect pollinator and their gene pools are totally >isolated - any sane person would give them the same name and put them in >the same folder in the herbarium - but should they? A systematist raised in the ornithological tradition of Ernst Mayr and the "biological species concept", as I was, would say without hesitation that the plants that look identical but persist as separate gene pools are certainly separate species; our inability to distinguish them easily is irrelevant. (Our inability to distinguish them easily would make them by definition "sibling species".) My sense is that the botanical tradition has not always seen things this way, but Jim or Iain may be able to correct my impression. (Ornithologists just wouldn't be sane botanists, maybe.) ;-) Linguists, I don't imagine, ever had furious ideological disputes over the essential difference between a language and a dialect, but in pre- evolutionary natural history there of course was an essential difference between species and varieties/subspecies: species were separate creations, whereas varieties/subspecies were not. You can't find a distinction more fundamental than that. Do linguists who work on different families of languages have different attitudes or approaches to language evolution? For example, do Indo- Europeanists tend to explain (say) sound changes in one way, whereas American Indianists explain the same sort of thing in some other way?

Their task would certainly have been much easier if they had considered the ecology of paleontological/paleobotanical systems long ago. I was lucky. My paleontological training had a great dose of ecology that considered all the aspects of the food chain, maybe because we often used modern coral reef systems as the examples and tried to see the equivalent aspects of ancient systems. _______________________________________________________________________________ Darwin-L Message Log 8: 1-30 -- April 1994 End
