Paleontologists have found fossilized multicellular marine algae, or seaweed, dating back more than 555 million years, ranking among the oldest examples of multicellular life on Earth. Honing in on ...

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] ...

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 ...

Top row: co-first authors Ang Gao (left) and Krishna Shrinivas (right). Bottom row: co-senior authors Arup Chakraborty (left) and Phillip Sharp (right). A computational model developed by scientists ...

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 ...

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 ...

In multicellular organisms, there is a potential risk that cheating mutants gain access to the germline. Development from a single-celled zygote resets relatedness among cells to its maximum value ...

Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when ...

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 ...

Honing in on when life on Earth evolved from single-celled to multicellular organisms is no easy task. Organisms that old lacked many distinguishing characteristics of modern life forms, making their ...
