In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy. Multicellular ...

Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

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 ...

At some point, organisms changed and grew from a single cell into one made up of many cells. But how that happened is not well understood. New work by graduate candidate Jonathan Featherston of the ...

One of the biggest evolutionary hurdles for life on Earth was the jump from single-celled to multi-cellular organisms…or at least, that’s what we thought. Scientists set out to replicate this ...

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 ...

Humanity can’t even figure out how to cryogenically freeze a single person for a short period of time. (Though NASA and Dippin’ Dots are both on the case.) But evolution has nailed keeping things ...

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 ...

If you look at the world around you now - at the plants, animals, and the people around you, it's easy to take for granted our multicellular existence. Life didn't always look like this. In fact, way ...

Researchers have discovered and characterized a new organism that will help scientists understand the molecular mechanisms and ancestral genetic toolkit that enabled animals and fungi to evolve into ...

Cassandra Extavour and her colleagues, who study the origins of multicellular organisms and the evolution of cooperation, still disagree on the meaning of key concepts such as cooperation, competition ...
