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 ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus. Yet ...

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 ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

Scientists are conducting a long-term experiment on evolution to investigate how single-celled organisms could evolve into multicellular lifeforms. After thousands of generations, their yeast grew ...

All the living things that we can see evolved from those that we can’t. Every human, bird, tree, and flower can trace its ancestry across a few billion years back to microscopic, single-celled ...

This article was originally featured on The Conversation. Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism ...

We've heard a lot about how important carbon and water are to life, but sulfur? Researchers think that sulfur may have actually been essential for organisms to make the transition from single-celled ...

Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...
