Scientists have discovered a worm that managed to stretch its short life expectancy — by tens of thousands of years.
A tiny roundworm was revived after it was frozen in Siberian permafrost 46,000 years ago, when Neanderthals still walked the Earth.
The nematode was found about 130 feet deep within the permafrost inside a burrow once home to Arctic gophers. After the chunk of frozen sediment was taken to the lab to thaw, the resurrected nematode crawled out and started making babies. The nematode, a female-only species, reproduces asexually, after about eight to 12 days.
