Fact of the Day: Ocean Ancestor

The first animals on Earth are believed to be ancient sea-sponge-like organisms that evolved from a flagellated eukaryote. The fossils providing the evidence for it were found in Australia in rock that was 665 million years old.

It's hard to pinpoint at what point we should call something the first animal on earth, some might argue that those eukaryotes would count.
