The Evolution of the Human Brain: How It Differs from Our.
Throughout the Pleistocene, brain size continues to increase further to that seen in modern humans, but again this increase in brain size is not related to a mean change in body mass. Brain size increase is arguably one of the most distinct and significant evolutionary trends in Pleistocene human evolution (Lee and Wolpoff, 2003).
Evolution of the Human Brain. - The purpose of this paper to examine the evolution of the human brain that distinguishes them from other species based on the traits that humans possess: such as language, emotional complexity and consciousness. The significance of traits are due to adaptations in humans to promote the survival of our ancestors.
Reorganization of the human brain is also apparent at the level of microstructure, such as distribution and morphology of neurons and glial cells. Human brain evolution is characterized by increase in expression of genes involved in energy metabolism, synaptic function, and plasticity.
The brain is formed of two types of nervous tissue, Grey matter on the outer side and White matter on the inner side. The former is made of non-medullated nerve cells whereas the latter is formed of medullated nerve cells. The brain or encephalon is a white, bilaterally symmetrical structure.
The human brain, in all its staggering complexity, is the product of millions of years of evolution. The brain has undergone some remarkable changes through its evolution. The most primitive brains are little more than clusters of cells bunched together at the front of an organism.
Human Brain Evolution In five pages the human brain and how it has evolved is discussed with a consideration of several relevant theories. Four sources are cited in the bibliography.
The human brain is a feat of evolution: it has allowed humans to have complex thoughts, conscience, build tools, create fires, and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state.

The Evolution of the Human Brain Essays - The Evolution of the Human Brain Although my previous two papers concerned the interplay between neurobiology and genetics, I have not quite worked the issue out to my satisfaction nor to the depth which I think the topic warrants.
The description of two major brain-specific genes associated with brain size evolution in human evolution provides genetic evidence for the introduction of new forms of genes or alleles in modern human populations that have originated from pre-human lineages.
Future analyses contrasting these fetal human brain gene networks with comparable data from mouse (as has been done for human and chimpanzee adult brain 138) should aid in identifying those genes whose importance in cortical development has increased in the course of human brain evolution.

The Human Brain vs. the Computer Over the millennia, Man has come up with countless inventions, each more ingenious than the last. However, only now, as the computer arises that mankind's sentience itself is threatened. Ridiculous, some may cry, but I say look about you!
