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 ...

A lot has changed on Earth in just the last few decades, but for a recently revived microscopic creature, it has tens of thousands of years to catch up on. In a new study published this week in the ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...

A billion-year-old fossil discovered in the Scottish Highlands may provide the "missing link" in how animals evolved. That "missing link" is the bridge between the transition of a single-celled ...

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 ...

Coordination between individuals is a fundamental challenge in collectives, and this is just as true for a country’s government as it is for simple multicellular organisms. How does a group of many ...

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 ...

Scientists were able to revive a tiny, multicellular animal called a bdelloid rotifer that had been frozen in the Siberian permafrost for 24,000 years, reports Marion Renault for the New York Times.

A new study led by researchers at Yale and McGill University reveals how fluctuations in the Earth’s oxygen levels over 700 million years ago may have set the stage for the diversification of ...

Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the ...

The original version of this story appeared in Quanta Magazine. Once upon a time, long ago, the world was encased in ice. That’s the tale told by sedimentary rock in the tropics, many geologists ...
