addendum to Anatomical # 1
- I just reread my "Anatomical # 1" post and discovered that I failed to
mention why all the similariteis between humans and chimpanzees is
significant in terms of evolution. Its pretty obvious, but just in case
someone misses the point let me state it.
One of the wonderful things about evolution is that it explains so much of
the biological world. In fact, it has been said (and is indeed true) that
nothing in biology makes any sense outside the context of evolution.
The similarities between humans and chimps stems from the fact that they
share such a recent common ancestor. Remember, as time has passed since the
speciation event(s) that have led to modern humans and chimps, each line has
independently accumulated slight differences. The fact that there really are
not a lot of tremendous differences between us and chimps is indicative of
very recent ancestry. If humans and gorillas are compared there is great
similarity also, but not as much as in humans and chimps because the common
ancestor of humans and gorillas is further back in time (but not much
further) - hence, there has been longer for differences to accumulate. Of
course, if we compare humans and monkeys the difference is even greater
because the common ancestor is even further back in time. Etc., etc.
I know this is elementary stuff, but I have had dialogue with persons in the
past, only to find out that they don't know the basics. I hope no one is
