Ron (the All American Amundson) asks:

>But, by the way, in what way does extragenetic inheritance imply
>inheritance of acquired characteristics?

The association is historical: Weissman's defense of the integrity of the germ
plasm was an attack on the inheritance of acquired characteristics.  The
emphasis on nuclear inheritance characteristic of Morgan et. al. was taken, by
some at least, as an endorsement of Weissmanism.  Correspondingly, cytoplasmic
factors were emphasized by neoLamarckians in Germany and (yes, you all American
fans) in the USSR.  Guilt by association it may be, but association it is

A good source for at least some of this is Bernhard Rensch's "Historical
Development of the Present Synthetic Neo-Darwinism in Germany," in Mayr and
Provine's *The Evolutionary Synthesis*.
