Which of the following has been suggested to have selected for bipedalism in the hominin clade? a. increasing parasite load, which promoted long-distance migration to escape from parasites. b. predators evolved faster movements, selecting for the ability of hominins to run faster. c. Transformation of forests into open savanna vegetation due to a drying climate; bipedalism was favored in open environments. d. Bipedalism allowed more efficient catching of fish and other aquatic organisms, which provided a plentiful source of protein. e. Bipedalism allowed the reaching of fruits that occurred higher on shrub and tree branches, helping to increase survival in environments where the diet was poor.

The smaller molars we see in the genus Homo (compared to the molars in Paranthropus species) suggest that Homo species had less male-male competition and fighting Homo species had molars just as large as Paranthropus species Homo species ate more meat and used tools and cooking to soften their foods Homo species only ate fruit, like chimpanzees

Modern humans, and probably Homo erectus, have much shorter intestines than expected for primates of their size. What possible change in hominin technology may account for this? Group of answer choices: - Increased hunting of easier-to-digest mammals, such as antelopes - The use of fire to process food - A shift from some hunting but mostly scavenging to mostly hunting - A reduction in food sharing, which also meant a reduction in food-borne diseases
