Computer simulations reveal feeding in early animal

What is it about?

Humans and other vertebrates (animals with backbones) are part of a major group known as deuterostomes, which also includes invertebrates such as sea urchins, starfish and acorn worms. It has been very difficult to work out what the ancestor of all these groups looked like and how it fed because the modern forms are so different from one another. However, by studying one of the earliest fossil echinoderms with the aid of sophisticated methods we have been able to learn more about our ancient ancestry.
