Behold the 540 million-year-old fossil remains of the earliest-known human ancestor! Saccorhytus was "likely an egg-shaped creature that ate and expelled from the same gaping orifice," just like Senior Counselor to the President Stephen Bannon.
"This may represent the primitive beginnings of a very diverse range of species, including ourselves," said co-author Simon Conway Morris, a professor at Britain's University of Cambridge. Saccorhytus belongs to a broad category of organisms called deuterostomes, and is the most ancient specimen unearthed so far…
The sack-like animal's most distinctive feature is a large — relative to the rest of its body — mouth ringed by concentric circles of raised bumps. It probably ate by engulfing food particles and microscopic creatures. Intriguingly, the researchers did not find anything corresponding to an anus.
