Exceptionally preserved fossils from the Ediacaran period challenge what scientists thought was possible in sandstone. In the fossil record, creatures without hard shells or skeletons, such as ...

This study from MIT explores eye evolution through AI simulations, uncovering how different tasks shape visual systems and ...

The evolution of some of the earliest complex animals on our planet may have been spurred on by other, simpler early animals. These simple marine animals first evolved around 560 million years ago and ...

A new study, led by the University of Vienna and the Alfred Wegener Institute in Bremerhaven, shows how the eyes of adult marine bristleworms continue to grow throughout life – driven by a ring of ...

A groundbreaking study suggests that the famous Cambrian explosion—the dramatic burst of diverse animal life—might have actually started millions of years earlier than we thought. By analyzing ancient ...
