A New Evolution Fight at Site of Scopes Monkey Trial
Lawyer and politician William Jennings Bryan argues for the prosecution during the Scopes Trial in Dayton, Tennessee, 1925.
For more than 80 years, Dayton, Tennessee has had a monkey on its back. That monkey is the English naturalist Charles Darwin, whose 200th birthday will be celebrated on Thursday in hundreds of cities around the world. Darwin's treatise On The Origin of Species was instrumental to the town's famous 1925 Scopes Monkey Trial, which pitted noted trial lawyers Clarence Darrow and William Jennings Bryan against each other in a fight to determine whether evolution should be taught in Tennessee public schools.

a Wisconsin-based atheist group called the Freedom From Religion Foundation rubbed it in by purchasing a 12-foot-by-25-foot billboard on the Southern side of town to remind them of Darwin's legacy — and his milestone birthday.
