In one of history's most fascinating coincidences, February 12, 1809 was the birthday of two of history's most extraordinary and influential figures - Abraham Lincoln and Charles Darwin. The historical parallel of their lives is the subject of David R. Contosta's dual biography  Rebel Giants: the revolutionary lives of Abraham Lincoln & Charles Darwin. Another comparison can be found in Adam Gopnik's book  Angels and ages : a short book about Darwin, Lincoln, and modern life. In addition both Newsweek and Smithsonian Magazine have recently published articles on this subject.
