Pretty much “banned” by politically correct society, now.
I own an old original copy.
Fascinating book.
That is interesting. In law school a woman from Purdue who studied anthropology determined that I had the skull of a masticulator (bark chewer) because of a ridge down the center of the top of my head. In researching Neandrathals and Cromagnums, I discovered they both had a boney structure on the inside of their jaws which I think I have. I think I am the missing link proving Darwin’s theory :>0
