Life How did multicellular life evolve? Algae and yeast give some hints Single-celled organisms that cluster and cooperate provide tantalising insights into the origins of multicellularity ...

The first life forms to appear on Earth were unicellular, i.e. composed of a single cell, such as yeast or bacteria. Later, animals - multicellular organisms - evolved, developing from a single ...

A new study finds that these controversial fossils are not likely to be bacteria or single-celled protists; their cells, preserved for more than 600 million years in rock, are too complex and ...

For simplicity, many unicellular lineages that are closely related to the multicellular lineages depicted here are not shown. The existence of such groups provides evidence that multicellularity ...

The most plausible phylogenetic interpretation for Horodyskia is that it represents a multicellular, giant-celled protist, which has acquired a large body size and shares some similarities with ...

Genomic Analysis of Organismal Complexity in the Multicellular Green Alga Volvox carteri. Science, 2010; 329 (5988): 223-226 DOI: 10.1126/science.1188800 ...

Matz says the giant protists' bubble-like body design is probably one of the planet's oldest macroscopic body designs, which may have existed for 1.8 billion years.

They closely resemble red algae, yet are 400 million years older than the previously earliest known examples of red algae, making them the oldest plant-like fossils by a wide margin.
