TimeTree

{via ERV}

Since I'm not, you know, a real scientist, this tool is of limited real use to me... but it's still awfully fun!

Time Tree will allow you to enter the name of two species and you'll get an estimate of when the branches leading to each species split form each other, based on collected molecular data. The more data collected on the two species, the better the estimtes, of course...

How long ago did koalas split from tree sloths? 160 million years ago, give or take.
Chimpanzees and bonobos? A mere 3 million years ago.
Humans and "magic mushrooms"? about 1.3 billion years ago.

I am, of course, somewhat dismayed that none of the results I've found to date are 6000 years. Obviously, science is broken.
