The Paranthropus Boisei is a species part of the H Robustus group of extinct humans.
They also are known as Zinjanthropus Boisei.
For a million years they developed jaws specialized to chewing tubers.
Chewing and more chewing.
They loved to chew and chew.
They chewed much more than we did, they were some of the best chewing apes to have ever existed and they are related to you.
But one day they died out, having nothing to chew anymore.
