Lucy, you got some 'splainin' to do.
The article said hominoids, not hominids. The term "hominoid" comprises the apes as well as the hominids.
Nope, you got some readin to do.
The fact is these scientists do not have the vaguest idea of when it appeared. All they know is that chimps and other monkeys nor anything they call 'primates' has it so they put the age back as far as they can. This assertion of over 20 million years also pushes back the man/chimp break back some ten million years farther which shows again that science keeps showing that man and monkey if at all related (as evolutionists would like us to believe) is a very, very, very far relation. It also gives them an excuse for spending another 150 years looking for the 'missing link' they never seem to find.
