Lake Vostok could have complex animals like shellfish or fish
Last year a team of Russian scientists achieved something that his country wanted since 1970: Drill a hole of more than 3,500 meters Antarctic Ice to reach the waters of lake Vostok , which has been buried for 14 million years and is kept in liquid due to geothermal heat from the Earth.
Six months ago it was announced that managed to draw water from that radical ecosystem , which has been meticulously analyzed by Russian scientists for some time to avoid embarrassing situations such as when claimed and later denied that found a new type of bacteria .
Already over time have begun to emerge early reports – to be received with caution because of the always possible sample contamination – which predict that the waters of Lake Vostok may have complex animals after analyzing the genetic material of the ice near the lake surface.
According to scientists, in the ice have found traces of organisms like bacteria commonly associated with marine mollusks, crustaceans and even fish, pointing out that the Antarctic lake could be being fed by a network of underground rivers from the ocean, as the lake is located 200 meters below sea level.
