A single-celled relative of animals forms colonies when exposed to a bacterial product, hinting at the possible origins of multicellularity.
Using an artificial selection paradigm, researchers watch as unicellular yeast evolve into snowflake-like clusters with distinct multicellular characteristics.
Tiny fossil tracks embedded in a California rock formation that was once part of an ancient river may be evidence that freshwater ecosystems arose around 100 million years earlier than what is generally believed. The existing fossil record dates t
The volvocine algae are a model system for studying the evolution of multicellularity, as the group contains extant species ranging from the unicellular Chlamydomonas to a variety of colonial species and the full-fledged multicellular Volvox varietie
The switch from single-celled organisms to ones made up of many cells has evolved independently more than two dozen times. What can this transition teach us about the origin of complex organisms such as animals and plants?
