Response:
Cremo and Thompson supported their claim with Vedic scripture. They
claimed scientific support for it, but the science they cite is old and
discredited.
More seriously, Cremo and Thompson were selective in what they cited.
The vast majority of evidence shows that hominids have developed more
or less gradually over the past 6 or more million years, and that
modern humans are much younger (Tattersall 1995).
