Blood cells carry a deep evolutionary history. A new analysis suggests their earliest ancestors were macrophage-like cells inherited from single-celled life.

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth—a geologic era when glaciers may have stretched as far as the Equator—a new ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...

New studies by the Max Planck Institute for Evolutionary Biology show that competition between different evolutionary developmental stages of multicellular life cycles can be important for the ...

Researchers at the Max Planck Institute for Biology Tübingen have shown that giant viruses long thought to exist only as ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

How low can worms go? According to a new study, at least 0.8 miles (1.3 kilometers) below the Earth's surface. Subscribe to read this story ad-free Get unlimited access to ad-free articles and ...

The death of an organism does not spell the end for its cells, according to new research. Cells have been shown to continue to function even after the organism they originated from is deceased, often ...

Newly discovered fossilized tracks suggest multicellular life could be 1.5 billion years older than previously thought, according to a new study. Newly discovered fossilized tracks suggest ...
