Braindance
by: dean Falk
In her book, Braindance, doyen Falk attempts to befuddle an explanation as to how the large head word coat in modern hominins came to be. She discusses early hominins such as Lucy, the firstborn australopithecine ever discovered from Taung, South Africa, and compares different fossil skull endocasts to the skulls of living primates, including human race. Her research looks to prove why the brain size in living earthly concern is three times larger than it was in our hominin relatives who lived more than three million years ago (Falk, 29). Her main hypothesis is that brain size has to do with a blood drainage and circulation system that would allow for proper cool down of a large, heat-generating organ, such as the brain of the modern Homo sapien. Thus, the discrepancy and natural selection that has occurred in Australopithecus and specimens belonging to the genus Homo has allowed for a larger brain because it could be properly cooled.
In her research, Dean Falk referred to studies on living primates such as chimpanzees to touch the differences and similarities in their relationship with humans, which share a common ancestor. These findings served to give a better understanding of the relationship between the brain of modern Homo sapiens and our earlier hominin ancestors and highlight those aspects of human behavior that dissociate us from other living primates (Goodall, 207). Although chimpanzees invite a cranial capacity of about 400 third-dimensional centimeters, and humans have a cranial capacity of about 1400 cubic centimeters (Zihlman, 5-18), the outward appearance of the brains of humans, chimpanzees, and other primates appear to have all the same parts. However, when comparing the intelligence of modern humans to the intelligence of a chimpanzee, for example, we see that chimps do have a sense experience of I or self,
