Did you know that we had a common ancestor with marine worms and starfish? According to the British magazine “Nature”, it would be a tiny one-millimeter aquatic creature, the “Saccorhytus”, with a bag-shaped body and an enormous mouth. Devoid of anus, he certainly used the 8 orifices scattered on his body to expel the water swallowed. It belongs like humans, starfish and sea worms, to the group of deuterostomes.
This creature was discovered, in its fossil form, by Chinese researchers in Shaanxi Province, Central China. The Saccorhytus lived 540 million years ago, and would be the oldest ancestor of Man!
