Answer the following questions, making sure to address every point indicated in each.
Was the emergence of bipedalism (the earliest appearance of bipedalism in the fossil record) associated with higher levels of intelligence and, therefore, with an expansion in the size of the brain? Explain your answer, making reference to either the accuracy or the inaccuracy of Darwin’s hypothesis on the origins of bipedalism (Keep in mind that the average cranial capacity of the chimpanzee is of about 450cc; use this measurement as a point of reference to determine when a significant expansion in brain size took place). (10 points)
Indicate the cranial capacity (whenever this information is given) of the different hominin species, from the earliest one to the latest one. For the genus Homo, only indicate the cranial capacities of Homo habilis and Homo erectus. (10 points)
At what stage in hominin evolution do we see a significant increase in the size of the brain relative to body size? Provide the name of the species associated with an increase in brain size, and the time when this is indicated in the fossil record.
To what particular type of behavior is a larger brain among hominins attributed to? The procurement of which resources is mostly associated with higher levels of intelligence among hominins, and why?
In relation to the previous question, indicate which landscape is associated with the increase in the size of brain in hominins. (10 points)
