Räuberisches Plankton schaffte nach der Phase der Vereisung auf der Schneeball Erde Raum für heutige Ökosysteme, wie ein Team um Forscher des Max-Planck-Instituts für Biogeochemie herausgefunden hat.

Around 635 to 720 million years ago, during Earth’s most severe glacial period, the Earth was twice almost completely covered by ice, according to current hypotheses. The question of how life survived these ‘Snowball Earth’ glaciations, lasting up to about 50 million years, has occupied the most eminent scientists for many decades. An international team, led by Dutch and German researchers of the Max Planck Society, now found the first detailed glimpse of life after the ‘Snowball‘ in the form of newly discovered ancient molecules, buried in old rocks.

Fossile Fettmoleküle, die aus 635 Millionen Jahre alten Gesteinen isoliert wurden, sind nicht die frühesten Hinweise auf erste Tiere, sondern entstammen chemisch veränderten Algenmolekülen.
