“A new study describing a microscopic, algalike fossil dating back more than 1.6 billion years supports the idea that one of the hallmarks of the complex life we see around us—multicellularity— is much older than previously thought. Together with other recent research, the fossil, reported today in Science Advances, suggests the lineage known as eukaryotes— which features compartmentalized cells and includes everything from redwoods to jellies to people—became multicellular some 600 million years earlier than scientists once generally thought.”
