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] ...

Cells can evolve specialized functions under a much broader range of conditions than previously thought, according to a study. Cells can evolve specialised functions under a much broader range 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 ...

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 ...

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 have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms. To human eyes, the dominant ...

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 ...

Until one or two billion years ago, life on Earth was limited to a soup of single-celled creatures. Then one fateful day, a lonely cell surrendered solitude for communal living. It developed a chance ...

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 ...
