Plus, what your voice would sound like on Mars. And the summer job in Wisconsin that makes teenagers jump off a moving boat to deliver mail.

Here's some cool stuff for your ride home.

Some wild animals are evolving up to four times faster than we previously thought.

Four times.

As a refresher from the University of Exeter, quote,

Darwinian evolution is the process by which natural selection results in genetic changes in traits that favor the survival and reproduction of individuals. The rate at which evolution occurs

depends crucially on genetic differences between individuals, end

quotes. Or as the researchers of this latest study refer to it, the fuel of evolution. Now, it's long

been emphasized, partially in response to colloquial uses of the term, that evolution is a very

slow process. That's certainly what Darwin theorized.

But more recent studies have shown that for some species, it can actually be quite quick.

Just a few years instead of millennia. And now a team of researchers from the University of

Exeter and the Australian National University have published findings in the journal Science indicating that that fuel of evolution in wild animals is moving as much as four

times faster than estimates from last century showed. The researchers poured over data from

19 populations of wild animals, including the superb fairy wrens in Australia, spotted hyenas in Tanzania,

song sparrows in Canada, and red deer in Scotland. And for each, they looked at when individual

animals were born, who they mated with, how many offspring they had, and when they died,
