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 ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

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 ...

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 ...

A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding ...

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 ...

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 ...
