The Rise of The Apes

It started 23 million years ago, which might seem like a long way in the past, but think of the earth as a person that lived to 100 years. When the Miocene began, this ‘person’ would have been ninety five years old. Everything that has occurred since then has been in the last 5 years.
The apes spread out and developed into 100 species, which included a couple we recognize today. We don’t know for sure which species contributed to the animal from which we descended, but molecular evidence strongly suggest it lived 7 to 8 million years ago. The mobile-on-two-legs version evolved in Africa later, about 5 million years ago.
