The facts of evolution come from observational evidence of current processes, from imperfections in organisms recording historical common descent, and from transitions in the fossil record. Theories of evolution provide a provisional explanation for these facts. [1] Each of the words evolution, fact and theory has several meanings in different ...
The interactions of genes with environment, called gene–environment interactions, are another component of the nature–nurture debate. A classic example of gene–environment interaction is the ability of a diet low in the amino acid phenylalanine to partially suppress the genetic disease phenylketonuria .
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.
Evolutionary psychology has been entangled in the larger philosophical and social science controversies related to the debate on nature versus nurture. Evolutionary psychologists typically contrast evolutionary psychology with what they call the standard social science model (SSSM).
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.

Edward H. Hagen writes in The Handbook of Evolutionary Psychology that sociobiology is, despite the public controversy regarding the applications to humans, "one of the scientific triumphs of the twentieth century." "Sociobiology is now part of the core research and curriculum of virtually all biology departments, and it is a foundation of the ...
Historically, interactionism has presented a limited view of the manner in which behavioral traits develop, and has simply demonstrated that "nature" and "nurture" are both necessary. [3] Among the first biologists to propose an interactionist theory of development was Daniel Lehrman. [4]
Evolutionary epistemology refers to three distinct topics: (1) the biological evolution of cognitive mechanisms in animals and humans, (2) a theory that knowledge itself evolves by natural selection, and (3) the study of the historical discovery of new abstract entities such as abstract number or abstract value that necessarily precede the individual acquisition and usage of such abstractions.
