Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

Prokaryotes are ancient, simple forms of life that include bacteria and archaea. These cellular life forms lack membrane-bound organelles. Those organelles, which include the nucleus and the ...

A lot happened in the hundreds of millions years separating the first and last eukaryotic common ancestors, but when and how most features arose remains a mystery. Eukaryogenesis is broadly defined as ...

In a study published in Science Advances on Jan. 24, researchers led by Prof. ZHU Maoyan from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences reported their ...

All modern multicellular life — all life that any of us regularly see — is made of cells with a knack for compartmentalization. Recent discoveries are revealing how the first eukaryote got its start.

Despite recent advances in the study of eukaryogenesis, much remains unresolved about the origin and evolution of the most complex domain of life. This year, University of Paris-Saclay biologist ...

An international collaboration between four senior scientists from Mainz, Valencia, Madrid, and Zurich has published groundbreaking research in the journal PNAS, shedding light on the most significant ...
