Paranthropus boisei
(Barbara Strnadova / Photo Researchers, Inc.)
Name: Paranthropus boisei, a human relative that lived in East Africa from about 2.3 million to 1.2 million years ago.
Dentition: Its massive jaw and flat molars gave rise to the belief that its diet consisted of nuts, which other nearby primates ate also. Its nickname is “Nutcracker Man.”
Nutrition: A new analysis of carbon isotopes in teeth from 22 individuals strongly suggests that P. boisei ate grasses and sedges instead.
Competition: “It was not competing for food with most other primates,” says Kevin Uno of the University of Utah, a researcher on the new study, “but with grazers”—ancestors of today’s zebras, pigs and hippos.
