The Human Brain Is The Product Of Adaptation And Not...

Evolutionary theorists argue the human brain is the product of adaptation and not unique amongst other species. Suzana Herculano-Houzel argues the human brain is merely an evolved form of a prior ape brain. Through comparative research, Dr. Herculano-Houzel has revalued the number of neurons within the human brain, as well as, many other common animals. Her research has led her to draw conclusions pertaining to human evolutionary development. She suggests the human brain is not a special or unique structure, but rather the evolutionary result of cooking. Ten years ago, brain researchers thought they understood the complex components of the human brain. They concluded that all mammalian brains were similarly made, and that the number of neurons within a given brain corresponded directly to brain size. These previously held ideas upset Suzana Herculano-Houzel because they were based upon little scientific evidence. She found both cow and primate brains to be relatively the same size, yet primates displayed a higher cognitive ability. Likewise, if brain size was an indication of cognitive ability, certain animals with larger brains should possess higher cognitive abilities than humans. However, previous neuroscientists dismissed these contradictions by referring to the human brain as â€Å"special.† Examples like these convinced Suzana Herculano-Houzel that all mammalian brains were not similarly made. She inquired to understand why the human brain was â€Å"special† and not bound byShow MoreRelatedHuman Race : The Myth An d The Truth1742 Words   |  7 PagesLilian Ogbuefi Clancy Smith Humanities 24 April 2015 Human races; the myth and the truth Introduction The human race as a result of its dynamism, roots, ability to adapt, acute intelligence, amongst other characteristics possessed, is undoubtedly the most unique of all earthly existence.

Humans have developed the capacity to begin to explore this realm in the twentieth century which represents a flash in the course of human evolution. Furthermore, through the process of natural selection, homo sapiens have evolved under a specific set of physiological constraints. These constraints have shaped the process of human development however they are not present in the same composition in spaceRead MoreArchaeology Notes19985 Words   |  80 Pages| | | W.
