We process information so effortlessly, automatically, and unconsciously that we are unaware it is happening. Instincts structure our thoughts so powerfully, that it can be difficult to imagine how things could be otherwise. For a number of years, human beings were held to be the products of culture, not of instinct. Human nature was simply the capacity to absorb culture - it had no other character. Three decades of progress and convergence in cognitive psychology, evolutionary biology, and neuroscience have shown that this view of the human mind is radically defective.
Evolutionary psychology provides an alternative framework that is replacing the standard model.
These circuits organize the way humans interpret experiences, inject certain recurrent concepts and motivation into mental life, and they provide universal frames of meaning that allow understanding of the actions and intentions of others. Concepts such as jealousy, friendship, beauty, and so on are not cultural inventions but instead are cultural elaborations of universal features of the human mind. Have you ever wondered about the fact that organisms which do not move do not have brains, and also do not possess language. For example trees, bushes, and grasses do not have brains. It is the circuits of the brain which are designed to generate motion in response to information from the environment.
