I don't know about you, but my ancestors have been evolving for a lot longer than 4 million years.

if you think Proteins are your common ancestor Yes, btw you don't have to know me to know 'what is correct' :-)

I think we have common ancestors with whales a lot more recently than proteins. It doesn't matter: we have common ancestors with them, therefore we've been evolving the same length of time.

This is the internet, where no-one knows if you're a non-DNA based lifeform -- as your first comment seemed to suggest.
