In a stunning scientific breakthrough, researchers from the University of California, Berkeley have discovered a living fossil in one of California’s untouched mountain lakes—a microscopic, ...

But complex multicellular organisms have arisen just six times on the tree of life: plants, animals, two groups of fungi, and two groups of algae.

The slightly warmer temperatures around the middle of the Earth melted the top layers of ice to form meltwater ponds that ...

Researchers have identified that species in the gut microbiome can produce sphingolipids that protect the host from pathogens.

Modern-day environments in Antarctica contain ponds filled with life forms that closely resemble early multicellular ...

Research from the University of Chicago provides a new view into key innovations that allowed modern, multicellular animals to emerge. By analyzing the proteins predicted from the genomes of many ...

Animals differ from other life forms like plants, fungi, and bacteria in key ways. They are multicellular, usually mobile at some stage, and rely on consuming organic material for energy.

Researchers have made a surprising discovery of Henneguya salminicola, a microscopic parasite residing in salmon muscles, as the first multicellular animal that doesn't breathe oxygen. This ...

The film explores the evolution of multi-celled animals, particularly sponges, from single-celled organisms like amoebas. It explains that the transition to multi-cellularity was driven by the ...

But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “ third state ” that lies beyond the traditional boundaries of life and death.

A unique experiment shows how multicellular organisms might have evolved from single-celled ancestors.
