Matthew Chapman, is a great-great grandson of Charles Darwin. He is also a journalist, screenwriter and film director. His speech (video links below) at the recent AAI Convention was entertaining and insightful. (A pdf file of the speech is here)
Chapman was born in Cambridge, England. Soon after moving to the US he became interested in the creationist attacks on evolution. This led to research on the Scopes Trial and a book Trials of the Monkey: An Accidental Memoir. In 2005 he reported on the Kitzmiller v. Dover trial for Harper’s magazine and wrote a book on this: 40 Days and 40 Nights.
