Here was a guy, Charles Darwin, in the middle 1800’s who sat in a little home in Kent at Down and because of his five-year experience on the Beagle, traveling around the world as a naturalist, designed an idea of evolutionary change which is the grand unifying theory of biology. Today, even though biology is leaps and bounds beyond Darwin in 1859, when he published The Origin of Species, the basic core of biology is still natural selection. But, Darwin was a very retiring person. He didn’t want to go out and defend his theories when he was being attacked by, particularly by the church, but by other scientists. But, Huxley, one of his colleagues, really became the defender of his ideas. He wrote a book with a wonderful title, Man’s Place In Nature. Of course, the terrible thing that Darwin did, was he removed humans from the center of the biological universe. He said that humans and human ancestors must have been susceptible to the same forces, the same whims and caprices of climatic change, evolutionary change, as any and all other living organisms. What Huxley tried to do in this book, was to really put man in his place in the natural world. I thought this was a brilliant idea. This was something that intrigued me, to realize that the same sort of plants and animals and insects that I was studying and was interested in — that we were there for the same reasons that they were. The same process of evolutionary change that brought about the Monarch butterfly, or the rabbits that I was observing in the neighborhood and so on, was the same process that brought us to where we are today.
