n“The record of evolution is still surprisingly jerky
and, ironically, we have
even fewer examples of evolutionary transition than we had in Darwin’s time. By this I mean that some of the classic cases of Darwinian change in
the fossil record,
such as the evolution of the horse in North America have had to be discarded or modified as
a result of more
detailed information--what appeared to be a nice simple progression when relatively few data
were available now
appears to be much more complex and
much less gradualistic.”
