The Ascent of Man, created by Rudolph Zallinger and published in Early Man by F. Clark Howell, parodied numerous times, continues to be a landmark in scientific illustration. And it does so despite the linear simplification of an otherwise complex tree, which has led, unfortunately, to misinterpretations that many of the detractors of evolution claim as proof of its falsity. I personally stand behind Carl Sagan's words: "Evolution is a fact, not a theory. It really happened".
