The most recent update of my Mac Mini desktop computer has Siri which I can use to ask questions. I asked Siri a question about our evolutionary relationship with chimpanzees. Siri gave me some websites including this very interesting article about how long ago the common ancestor of chimpanzee apes and human apes lived.

Ancestors Of Humans And Chimps May Have Begun Diverging 13 Million Years Ago

I learned quite a bit about evolutionary clocks from this article.

Another article I found: Why Haven't All Primates Evolved into Humans?

"To say we are more 'evolved' than our hairy cousins is just wrong. (See how long you last naked in the Congo Heartland, and then tell me who's got the evolutionary upper hand.)"
