Free Online Paleoanthropology “Textbook”: John Hawks Blog

I’ve never seriously studied anthropology, paleontology, or paleoanthropology.  When I read someone who seems or claims to be an expert on paleoanthropology or certain aspects of evolution, it requires a degree of trust on my part. 

(I have a stronger background in evolution, thanks to a B.S. degree in Zoology.  I was thoroughly indoctrinated in the mid-1970s.)

It was a slow day at work, so I just spent a couple hours perusing the blog of an actual paleoanthropologist named John Hawks.  It’s a massive database that may be the equivalent of a paleoanthropology textbook.  Naturally, it will reflect the biases of the author, if any (and we all have some, don’t we?) . 

Some interesting things you’ll find there:

Regarding the pace of human evolution in the Neolithic period, Artemis P. Simopoulos (with The Center for Genetics, Nutrition and Health in 2009) has a different view:

The spontaneous mutation rate for nuclear DNA is estimated at 0.5% per million years.  Therefore, over the past 10,000 years there has been time for very little change in our genes, perhaps 0.005%.  In fact, our genes today are very similar to the genes of our ancestors during the Paleolithic period 40,000 years ago, at which time our genetic profile was established.

I dunno; you decide.
