Revealed, Human Ancestors More Similar Cow

Results of recent anthropological studies revealed that human ancestors, Paranthropus boisei, proved to have a cow-like behavior than ordinary people.
Previously, there were estimates, strong jaw Paranthropus boisei used to eating nuts, seeds, and fruits. Now, the results of recent studies indicate Paranthropus boisei teeth used to cut and eat the grass in large quantities.
"We did not expect to find a primate who have the habit of eating like a cow in the family tree of human ancestors," said Professor Matt Sponheimer of the University of Colorado Boulderdi United States (U.S.).
Paranthropus boisei is part of the human lineage brother, known as australopithecines. Fossil australopithecines comes from Ethiopia and an estimated three million years old. This fossil is also known as Lucydan alleged 'modern ibu'manusia.
About two and a half million years ago, the australopithecines are divided into two two groups, namely homo sapiens (modern humans beginning) and type Paranhropus who later became extinct. The first fossil Paranthropus boisei or 'Nutcracker Man'ini discovered in Tanzania in 1959.
