From Asgard to Earth: Tiny tubes may reveal the moment complex life began

Phys · · 1043 words · By University

A scientific study published in Current Biology reveals that stromatolites and microbial mats may hold insights into how complex life began. Researchers identified a previously unknown microbe in these structures, which could explain how simple cells formed partnerships to create eukaryotic cells. The discovery highlights the role of microbial cooperation in the evolution of life and includes cultural recognition of Indigenous languages in naming the new archaeon.
