While EDP theory generally aligns with that of mainstream EP, it is distinguished by a conscious effort to reconcile theories of both evolution and development. [5] EDP theory diverges from mainstream evolutionary psychology in both the degree of importance placed on the environment in influencing behavior, and in how evolution has shaped the ...
Erik Homburger Erikson (born Erik Salomonsen; 15 June 1902 – 12 May 1994) was a Danish-German-Jewish child psychoanalyst and visual artist known for his theory on psychosocial development of human beings. He coined the phrase identity crisis.
Erikson published a book called Childhood and Society in 1950 that highlighted his research on the eight stages of psychosocial development. [3] Erikson was originally influenced by Sigmund Freud's psychosexual stages of development. He began by working with Freud's theories specifically, but as he began to dive deeper into biopsychosocial ...
Loevinger's stages of ego development, 'conceptualize a theory of ego development that was based on Erikson's psychosocial model', as well as on the works of Harry Stack Sullivan, and in which 'the ego was theorized to mature and evolve through stages across the lifespan as a result of a dynamic interaction between the inner self and the outer ...
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.

Erik Erikson (b.1902) developed a psychosocial developmental theory, which was both influenced and built upon by Freud, which includes four childhood and four adult stages of life that capture the essence of personality during each period of development. [8] Each of Erikson's stages include both a positive and negative influences that can go on ...
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.
