Dan gives an amazing lecture about evolution while sculpting a young Darwin, who ages as the lecture/sculpting moves along. It's a breathtaking display of interdisciplinary work.
And, of course, Darwin was himself an interdisciplinary thinker. In fact, 18th and 19th-century scientists were often thought of as natural philosophers and/or naturalists. It wasn't unusual for Darwin to be as interested in geology as he was in marine biology, as competent in botany as in zoology. Big problems (and evolution is one of THE big problems) require knowledge of all sorts, data of many kinds, and a general ability to synthesize information from various sources.
So, welcome Mr. Darwin.
