Shedding light on Earth’s first animals

More than 550 million years ago, the oceans were teeming with flat, soft-bodied creatures that fed on microbes and algae and could grow as big as bathmats. Today, researchers are studying their fossils to unlock the secrets of early life. Researchers now show that Dickinsonia developed in a complex, highly regulated way using a similar genetic toolkit to today’s animals.
