Evolutionary psychology connects evolutionary principles with modern psychology and focuses primarily on psychological adaptations: changes in the way we think in order to improve our survival.

Two major evolutionary psychological theories are described: Sexual strategies theory describes the psychology of human mating strategies and the ways in which women and men differ in those strategies.

That is, the peacocks’ feathers act like a neon sign to predators, advertising “Easy, delicious dinner here!

Other examples of survival adaptations include developing a craving for fats and sugars, encouraging us to seek out particular foods rich in fats and sugars that keep us going longer during food shortages.

Some threats, such as snakes, spiders, darkness, heights, and strangers, often produce fear in us, which encourages us to avoid them and thereby stay safe. However, all of these adaptations are for physical , and help us compete for mates.

That is, just as peacocks display their feathers to show how attractive they are, or some lizards do push-ups to show how strong they are, when we style our hair or bring a gift to a date, we’re trying to communicate to the other person: “Hey, I’m a good mate! So how could someone ever say that such behaviors are “biologically programmed” into us?

Well, even though our ancestors might not have been doing these specific actions, these behaviors are the result of the same driving force: the powerful influence of evolution.

Yet every living human being is an evolutionary success story.

Each of us is descended from a long and unbroken line of ancestors who triumphed over others in the struggle to survive (at least long enough to mate) and reproduce.However, physical survival is only important if it eventually contributes to successful reproduction.That is, even if you live to be a 100-year-old, if you fail to mate and produce children, your genes will die with your body.It is possible that we have been taught these behaviors by observing others.It is also possible, however, that these behaviors—the fancy clothes, the expensive restaurant—are biologically programmed into us. " However, we all know that our ancestors hundreds of thousands of years ago weren’t driving sports cars or wearing designer clothes to attract mates.Yes, evolution—certain traits and behaviors developing over time because they are advantageous to our survival.
