The world would look very different without multicellular organisms – take away the plants, animals, fungi, and seaweed, and Earth starts to look like a wetter, greener version of Mars. But precisely ...

Learn how one-celled organisms, or single-celled organisms, helped build complex life.

The origin of animal multicellularity is one of the major evolutionary transitions in the history of life. The identification and phylogenetic classification of the closest unicellular relatives of ...

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 ...

Scientists have long thought that there was a direct connection between the rise in atmospheric oxygen, which started with the Great Oxygenation Event 2.5 billion years ago, and the rise of large, ...

The spherical fossils came from sediments that were formerly at the bottom of a lake. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures.

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 ...

Over 3,000 generations of laboratory evolution, Georgia Tech researchers watched as their model organism, “snowflake yeast,” began to adapt as multicellular individuals. [email protected] ...
