It's a microscopic worm called a rodefer that was brought back to life after spending

about 25,000 years locked in the Arctic permafrost.

Its tail is told in the journal Current Biology.

This is a long term topic for our lab.

Many and his colleagues have spent decades probing the Siberian permafrost.

And they've managed to revive a variety of interesting organisms, from a plant seed

and simple bacteria to scores of more sophisticated single-celled critters.

We have isolated around 30 or maybe 40 strands already or unicellular carriers.

But for some reason, people weren't totally wowed by resurrected amoebas.

Yeah, they're done to speck now.

It worked for as much better.

Rodefers are better, or at least more interesting, because they're multicellular animals, with

a head and a body that can eat, crawl around, and make more rodefers.

Then considering they're more or less teeny tiny worms, they're actually cute little
