Unbroken Mitochondrial line?

[popeyespappy]

Human population have been studied. Now forget the human population. Apply same algorithms and DNA testers to the Monkey population. How old would be monkey-Eve?

Depends on how you define monkey. If you limit it to old world and new world monkeys then applying our best guess at a mutation rate algorithm tells us their most recent common ancestor lived about 40 million years ago. The same algorithm tells us apes split from old world monkeys 25 to 30 million years ago, tarsiers split from old/new world monkeys and apes about 55 million years ago, and lemurs and lorises split about 60 million years ago.
