Describe evidence used by scientists to determine whether early hominins were browsers (eating shrubs primarily) or grazers (eating grasses primarily).

Solution

Paleoanthropologists,have long relied on skull and tooth morphology to infer hominin diets,but they have also looked to microscopic wear traces in dental enamel and they have looked increasingly to the stable isotope composition of skeletal tissues.

In tropical and subtropical environments,the tissues of plants that follow a C4 photosynthetic pathway,tend to enrich in 13C related to 12C.The C13/C12 ratio is recorded in various tissues,but from a fossil perspective,dental enamel is by far the moat important.

The carinodentaldental morphology of P.boisei might also have spaculate that it relied on grassy foods to a perticularly great extent,rivaling only galada baboons among known primates.
