The flexibility in behavior and decision making although of obvious evolutionary advantage also enables us to choose not to have children and to commit suicide.
Largest brain Compared to mammals as a whole, humans have the largest EQ Encephalization quotient - brain-to-body mass ratio. There is at least this much agreement about human language - it is a form of communication that is unique in the natural world.
Some body language is certainly genetically inherited and consistent among all humans. For this reason, such conditions are far more common in males than in females. On average, the INAH-3 is significantly larger in males than in females regardless of age.
Conclusion Men and women are alike and different in many ways.
The former usually occurs under chronic stress, the latter is caused by acute fear. On average, for example, men tend to have a larger amygdala, a region associated with emotion.
This may be because the female auditory cortex is more dense than that of the male. Ethology began as the science of animal behaviour. The aquatic-ape hypothesis advocates semi-aquatic existence of ancestral hominins during million period between 6 and 8 million ago.
The left hippocampus, for example, an area of the brain associated with memory, was usually larger in men than in women. As did early gatherers, they scope the scenery for a broad view of their surroundings keeping in sharp awareness of their immediate context.
Body language also arguably covers all that we communicate through our bodies apart from the spoken words thereby encompassing breathing, perspiration, pulse, blood-pressure, blushing, etc.
Prenatal sex hormones are known to alter behavior and certain brain structures in other mammals. She concludes her article by stating: The early appearance of any sex difference suggests it is innately programmed—selected for through evolution and fixed into our behavioral development through either prenatal hormone exposure or early gene expression differences.
One of these patches, the beard, begins to grow during puberty, and is thickest in young adulthood and full maturity, tending to decline in old age.
Freeze, flight, fight, fright, faint: Males have a larger intra-hemispheric long-range interconnectivity than females, whereas females have a larger inter-hemispheric connectivity. Women think with the white matter, which consists more of connections between the neurons.
Our interpretation of body language, notably eyes and facial expressions, is instinctive, and with a little thought and knowledge we can significantly increase our conscious awareness of these signals: It can be divided into four areas: Daniel Goleman, author of Emotional Intelligence, accomplished the same end.
It contains two important structures called the thalamus and the hypothalamus. Jump to features not unique to humans. Humans share a lot of features with other vertebrates, other mammals, and, of course, other apes.
The Female Brain movie follows the fictionalized “Julia” Brizendine: a neuroscientist who explains the relationship dynamics of her friends through her research. But how accurate is. Of course, there's isn't a simple answer to that question. While some brain features are more common in one sex than the other, and some are typically found in both, most people have a unique mix.
Male and female brains actually differ right down at the genetic level in quite a drastic way. Studies reveal that typically EVERY CELL in the male brain contains a Y chromosome.
A comparison of male circumcision to female circumcision. If female circumcision is genital mutilation, is male circumcision genital mutilation? Psychology Today: "The Male and Female Brain Are More Similar Than Once Assumed." Nisbett, R. American Psychologist, February-March News release.Male vs female human brain
