And in humans, we call it the body clock.

A search in the genomes of vertebrates revealed a set of analogous genes, which were found to play similar roles in the mouse biological clock and therefore almost certainly in the human biological clock as well.

So fine, we have a body clock, and it turns out that it's incredibly important in our lives.

The first biological clock genes, for example, were identified by examining Drosophila mutants that showed disrupted daily activity cycles.

There's a clock, clock, clock, clock.

This was like a biological desert.
