[sci.bio] Numbers in biology

dwilson@gozer.uucp (David Wilson {x6203}) (03/29/91)

I am compiling interesting and/or significant information on the
integers 0 through 100, in hopes of one day publishing a book.
I am posting to this newsgroup to specifically request references
from biological and related fields, although I welcome any interesting
tidbit.  For instance, I understand that:

    Most vertebrates have 7 "neck bones" and 5 "fingers" on each
    "hand." 

    Human beings have 46 chromosomes, as well as some closely
    related species.

    Gourds often have 10 stripes.

If you would care to elaborate on the above observations, or have
any of your own, from biology or any other field, please e-mail to me.

Where did you get this information?  I think that it's probably wrong
if most means most species, but I'm even more sure it's wrong if you
mean most in terms of absolute number.  Amphibians only have 4 fingers
at the end of each forelimb, and there are an awful lot of frogs out
there... Also, most birds have lost some of their fingers, and the few
that remain can hardly be called that.  You also might want to look at
artiodactyla (e.g. pigs, hippopotami, camels, deer, giraffes,
antelope, sheep, goats and cows).  (Artiodactyl means "having an even
number of toes"...)
