Scientists have just sequenced the genome of a fly native to Antarctica, the coldest, driest and windiest place on the planet, a finding that may lead to a wider understanding of how these bugs evolved to cope with the environment.
The fly, named Belgica antarctica, is a survivor, or as Washington State University evolutionary biologist Joanna Kelley likes to put itan extremophile.
This fly has to withstand freezing, extreme temperature changes so in the Antarctic summer its on the rocks and those are getting quite hot, Kelley said. But imagine the Antarctic winter, its very dark and cold. Theres a lot of UV [ultraviolet] radiation. Theres dehydration. And anything you can imagine as an extreme pressure, this fly probably encounters it.
Common fly
The fly is a midge, a group of small flies found practically everywhere on earth.
This midge has evolved to survive in the extreme environment of the rocky outcrops of the Antarctic Peninsula.
It is wingless, so it cant be swept up by the wind and blown into the sea. It can also tolerate 40 percent or more water loss in its cells, more than double that of other midges.
