Evolutionary psychologists consider Charles Darwin's theory of natural selection to be important to an understanding of psychology. [1] Natural selection occurs because individual organisms who are genetically better suited to the current environment leave more descendants, and their genes spread through the population, thus explaining why organisms fit their environments so closely.

Dual inheritance theory (DIT), developed in the late 1970s and early 1980s, has a slightly different perspective by trying to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. DIT is seen by some as a "middle-ground" between views that emphasize human ...
Both Darwin's theory of evolution and Karl Ernst von Baer's developmental principles of ontogeny shaped early thought in developmental psychology. [12] Wilhelm T. Preyer, a pioneer of child psychology, was heavily inspired by Darwin's work and approached the mental development of children from an evolutionary perspective. [14]
Whereas neo-Darwinism defines evolution in terms of changes in gene distribution, the possibility that an evolutionarily significant change may arise and be sustained without any directly corresponding change in gene frequencies is an elementary assumption of developmental systems theory, just as neo-Darwinism’s ‘explanation’ of phenomena ...
The evolution of cognition is the process by which life on Earth has gone from organisms with little to no cognitive function to a greatly varying display of cognitive function that we see in organisms today. Animal cognition is largely studied by observing behavior, which makes studying extinct species difficult.
Ecological systems theory is a broad term used to capture the theoretical contributions of developmental psychologist Urie Bronfenbrenner. [1] Bronfenbrenner developed the foundations of the theory throughout his career, [2] published a major statement of the theory in American Psychologist, [3] articulated it in a series of propositions and hypotheses in his most cited book, The Ecology of ...
A new scientific theory connects mysterious structures deep within Earth's mantle to a violent collision with the protoplanet Theia. A new scientific theory connects mysterious structures deep ...
In evolutionary psychology, people often speak of the four Fs which are said to be the four basic and most primal drives (motivations or instincts) that animals (including humans) are evolutionarily adapted to have, follow, and achieve: fighting, fleeing, feeding and fucking (a more polite synonym is the word "mating").
