Evolutionary psychology is founded on several core premises.
1.The brain is an information processing device, and it produces behavior in response to external and internal inputs.[4][13]
2.The brain's adaptive mechanisms were shaped by natural and sexual selection.[4][13]
3.Different neural mechanisms are specialized for solving problems in humanity's evolutionary past.[4][13]
4.The brain has evolved specialized neural mechanisms that were designed for solving problems that recurred over deep evolutionary time,
[13] giving modern humans Stone age minds.[4]
5.Most contents and processes of the brain are unconscious;
and most mental problems that seem easy to solve are actually extremely difficult problems that are solved unconsciously by complicated neural mechanisms.[4]
6.Human psychology consists of many specialized mechanisms, each sensitive to different classes of information or inputs.
These mechanisms combine to produce manifest behavior.[13]
