How does multicellularity evolve? Scientists who study a family of green algae that includes unicellular Chlamydomonas and multicellular Volvox are beginning to find answers to this question.

Shown are representatives of all major lineages of eukaryotic organisms, color coded for occurrence of multicellularity. Solid black circles indicate major lineages composed entirely of ...

“It’s very cool to demonstrate that [multicellularity] can happen so quickly,” said evolutionary biologist Mansi Srivastava of the Whitehead Institute for Biomedical Research in Massachusetts, who was ...

Researchers identify a molecule that may have been key to the surprisingly common transition from single-celled ancestors to today’s complex, multicellular organisms. Jef Akst was managing editor of ...

Caption Representative diverse origins of multicellularity are shown on a highly redacted and unrooted phylogenetic diagram of the major eukaryotic clades (modified from a variety of sources ...

According to scientists from the University of Geneva, this organism can form multicellular structures resembling early animal embryos, providing insight into the origins of multicellularity.

This elaborate example of cell communication offers key insights into the early evolution of animal multicellularity and nervous systems. Researchers from the Burkhardt group at the Michael SARS ...
