and early twentieth centuries, In fact, the benefit of selective breeding was so irrefutable, that English mares had been segregated from stallions except for planned breedings since the 1100s (Shipman, Pg. 21).
             Darwin could see that his natural selection would fuel the process of adaptation to differing habitats by differential survival and reproduction-this group living in a more arid area than that one, or the one population coping with denser vegetation than the other. Adaptations would, of course, be manifested physically, in longer or shorter limbs, thicker of thinner fur, more pointed of blunter beaks, and so on, each set of traits typifying a different group according to it's ecological niche.
             If this were so, then the process of evolution occurred over vast amounts of time. If this were so, there ought to be intermediates, traditional forms, species caught in the act of evolving from one thing to another. Where was this " infinitude of interconnecting links"? Darwin mulled over this stumbling block for a long time. Eventually he came to believe that most of these transitional species of populations would have been exterminated, because the linking populations would be by definition less well adapted than their adaptive neighbors, whose superior numbers and more suitable adaptations would overwhelm the intermediates, It was to be expected that the links would be missing, Darwin concluded contentedly. Once the intermediates or links were destroyed, what was left formed a diverse array of separate species, all sufficiently similar to be grouped into a single genus and each beautifully adapted to its habitat, Time and natural selection are the only two prerequisites.
             Darwin never imagined that his idea would influence so many racist ideas. It was simply meant to explain how so many organisms came to be. He simply had a theory that hereditary modification was possible. However, the future held that several people would use his...
