A new study shows that multicelled organisms like the metazoan daphnia (pictured) require a tenfold increase in energy compared with protists for their growth, maintenance and survival. The high cost ...

How do living organisms that lack a brain or nerve cells make decisions? In a new study published in May 2021 in the Proceedings of the National Academy of Sciences of the United States of America ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...

Algal cells that cheat are more vulnerable to stress. This trade-off could help explain the emergence of multicellular organisms, and what keeps cells in algae and cells in our bodies cooperating with ...

For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth — a geologic era when glaciers may have stretched as far as the Equator — a new ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

This article was originally featured on The Conversation. Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism ...

Over 3,000 generations of laboratory evolution, Georgia Tech researchers watched as their model organism, “snowflake yeast,” began to adapt as multicellular individuals. catherine.barzler@gatech.edu ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...
