The law, which passed in January of 1925, stated that it was illegal for anyone to teach anything but the story of Divine Creation of man. After an eight day trial, Scopes was found guilty of teaching evolution and fined 100 dollars (approximately 1,165 dollars in today’s currency.)

On July 10, 1997, London scientists report their DNA analysis of a Neandertal skeleton, nicknamed African Eve, found in modern day Ethiopia. The results place her life at roughly 140,000 years ago, which supports the Out of Africa Theory. This theory states that all our ancestors originally came from Africa. An alternative theory is the Multiregional Origin Theory, which states that our ancestors developed independantly in different regions of the world.
