Question

what is the role of human brain comparing other organismes

Answer 1

Human Brain has a more developed cognitive functions due to highly developed forebrain and a more thick layer of cortex in compare to other animals' brain. The most important difference is relative brainsize, a very large cortex and a very developed prefrontal cortex.

The brain is the most complex organ in the body. The brain is made up of a complexnetwork of billions of nerve cells called neurons, as well as other kinds of cells, all protected by the bones of the skull.

Answer 2

1) Human have a 3 times bigger relative brain size (relative brain size: the analogy between body mass/weight and brain size..) However, solely the fact that the human brain is 3 times larger than its expected size, does somewhat make the human brain unique.

2) The connectivity of the neurons in the brain and in particular the cerebral cortex are more developed than in other non human primates.however, the neural connections in a human brain are more developed. The above said (developed neural connectivity has been linked with enhanced intelligence)

3) As far as the genetic influences are concerned, the gene which is associated with speech and language has been apparent in our ancestors as well....how come chimpanzees which has the same gene as humans could not speak and we can? environment i dont think plays a specific role in brain evolution itself. it does play a significant role in education and our acquired knowledge, morals etc etc but the physical properties of these procedures and how such information gets processed remains the same-similar to other primates!.
