The Evidence Furnished by Anthropology 



not their descendants but that we have descended from an- 

 other race and that there is much evidence to support the 

 behef that we have come from the Piltdown race. But where 

 have they been during these 100,000 years? It has been 

 suggested that on the coming of the great Ice Age, some of 

 the other races moved on down into the tropical fertile coun- 

 try that is now the Sahara desert and there they lived and 

 multiplied and after the ice of the North had disappeared, 

 they returned again and exterminated the Mousterians in a 

 series of savage wars. There is much evidence to support 

 this theory that removes it from the realms of fancy. 



When Cultural Evolution began among the ancestors of 

 man, the electronic forces of his brain became more active. 

 Brain cells began to multiply. New experiences gave origin 

 to new ideas and new ideas called for new brain cells to carry 

 these new ideas into execution and, as a consequence, these 

 accumulating cells gathered in folds or convolutions and 

 pushed the skull out and up. The skulls of some of the primi- 

 tive tribes were long; some were broad and round but they 

 all grew out and up. When man began to make things with 

 his hands, the making of which was directed by his brains, 

 the development of his skull which after all is only a bony 

 encasement for the brains, began a rapid development. The 

 useful discoveries of one tribe or race were passed on and 

 copied by other tribes and races just as is done to this very 

 hour. Skulls of primitive man found in Southern Africa, in 

 Australia, in Asia and in nearly all parts of Europe give 

 unmistakable evidence of contemporary development. The 

 form and character of the tools and weapons they used show 

 also a contemporaneous development.
