After reading the paragraphs below, answer the questions that follow.

Bipedalism is one of the most important characteristics of hominin evolution. The appearance of bipedalism led to anatomical changes that are considered to be distinguishing characteristics of hominin fossils. The evidence for bipedalism is supported by fossil evidence from more than 4 million years ago and 3.6-million-year-old footprints in volcanic ash.
Recently, however, scientists have focused on the link between tooth structure and diet in the evolution of the early hominins, specifically in Australopithecus species. Detailed studies of hominin dental features have provided evidence of an important dietary shift that led to adaptive radiation within this genus. Most of the evidence comes from analyses of tooth size and shape, microscopic wear patterns on teeth, and jaw structure. The evidence suggests that fibrous plant materials became more important through the Pliocene, perhaps as critical components in the diet of some species.


Evidence from fossil dentition suggests that Australopithecus species
◦ evolved specifically to eat meat.
◦ experienced a decrease in both tooth size and brain size.
◦ were adapted to function successfully in a wide range of habitats.
◦ were direct ancestors of modern humans.

Did you know?

You should not take more than 1,000 mg of vitamin E per day. Doses above this amount increase the risk of bleeding problems that can lead to a stroke.

Did you know?

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Did you know?

The first oncogene was discovered in 1970 and was termed SRC (pronounced "SARK").

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Did you know?

More than 4.4billion prescriptions were dispensed within the United States in 2016.
