I am replying to this based on memory from Human genetics classes MANY
years ago.  That being understood, as i recall no primates are capable
of metabolizing Vitamin C, presumably because until about 5-10 Ma, they
all obtained plenty from their very fructivorous diet.  Because there
was no need to produce it, we never developed (or lost) the ability to
do so.  It has been a critical problem in human and australopithecine
development, and may have severely limited the early spread of
hominids to northerly climates.

It has been used as justification for the use of megadoses of Vit C
to prevent colds, arguing that other mammals get fewer and less severe
colds (Rhinoviruses?) because they manufacture their own C.  I would
love feedback on this issue.
