THE GOAL OF EVOLUTION 241 



The appendix will be reduced to the vanishing point, and 

 good riddance, along with one or two ribs and perhaps the 

 little toe. Physiologically the heart may beat faster in a body 

 at higher temperature, and so on. But these are all minor 

 changes of little or no value in the success or failure of man- 

 kind. 



Man could, of course, select the kind of streamhned phy- 

 sique he most preferred from any of the types now repre- 

 sented in the world populations and segregate out a race 

 which would breed closely to this standard; that is, if he 

 could ever bring about an agreement on the type to be pre- 

 ferred. Some orientals would not be too enthusiastic about 

 adopting as a standard what to them is the overly skinny, 

 narrow-hipped female of the western world. Man could, for 

 instance, so control the selection as to make the glamor of 

 the Hollywood type the standard birthright of all. It would 

 be no more difficult than streamlining the Kentucky Derby 

 winner; it would only take a longer time. Of course, we 

 know that man will never breed to such physical pedigrees, 

 and we also know that it would do him no good if he did. 

 The problems of social and mental life would not be more 

 easily solved because the individuals of a population were 

 narcissistically concerned for their beauty. 



Population geneticists, Hke W. C. Boyd, see in future 

 man a blending of present racial differences in which the 

 predominant characteristics will be chiefly a contribution of 

 the present peoples of Asia and Africa and parts of Central 

 and South America. Europe and North America will make 

 only a minor contribution to the make-up of this future 

 man. The present fantastic birth rates in Asia and Africa (43 

 per 1,000 as compared to European averages of 19 to 22 per 

 1,000), along with the already disproportionate ratio of yel- 

 low, brown, and black over white, seems to these observers 

 to make it rather certain that future man will have brown 

 eyes and brown skin and black, straight hair.
