The unibrow is about to make a comeback.

The first complete genome of a Neanderthal — specifically, the mitochondrial DNA found in a 38,000-year-old bone — has been sequenced.

The highly accurate sequence contains clues that our relatives lived in small, isolated populations, and probably did not interbreed with their human neighbours.

This is both cool and a little worrying.

I am hoping that these scientists don't start thinking of cloning big hulking bodyguards to keep those tough astrophysicists from giving them swirlies.
