Tchadanthropus (uxoris) is the subject of debate as to where the fossil remains belong in the scientific classification system. There are arguments for it being an archaic Homo sapien (heidelbergensis), a synonym of Homo erectus and same favor a Homo sapiens classification. Still others indicate it should be considered an unidentified specimen as it’s condition doesn’t allow for accurate measurement even though it’s estimated between 700,000 to 900,000 years old.
A high school substitute teacher, John Scopes, was accused of teaching human evolution in Dayton, Tennessee where it was against the law (Butler Act) in 1925. The trial became known as the Scopes Monkey Trial. It was never clear he actually did teach evolution, but the attention the trial brought to the subject and location made it much of a publicity stunt. The lawyer for the prosecution was William Jennings Bryan who was an active anti-evolutionist as well as a politician. When Bryan was embarrassed by questions from defense lawyer Clarence Darrow, the judge expunged the testimony and the case was closed without a summation, Bryan being declared the winner. The Tennessee Supreme Court reversed the lower court’s decision and Scopes was released a free man.
