========
The earliest primitive primates are about 55 million years ago. The old-world new-world split comes about 36 million years ago. Apes split from monkeys IIRC about 30 million years ago. The line leading to humans diverges from the line leading to chimps 5-7 million years ago.
That's pretty much what I learned in school some (unspecified) years back. Some of what I learned has changed, but mostly it is filling in the details.
I guess that means Australo was not on the monkey line, eh? (only missed by 25-30 million years, but who's counting.
Sometimes the demands from the other side to "bring me the broomstick of..." get a little silly.
