  2. Evolutionary psychology of parenting - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_psychology_of...

    According to the parental investment theory, mothers are inclined to provide optimal care for their offspring due to the certainty of a genetic relationship. In regards to this, polyandry is rare in most societies as women will not take more than one husband in order to ensure the father with knowledge of the child's paternity and assistance with future care of their child from the father.

  3. Continuum concept - Wikipedia

    en.wikipedia.org/wiki/Continuum_concept

    The continuum concept is an idea, coined by Jean Liedloff in her 1975 book The Continuum Concept, that human beings have an innate set of expectations (which Liedloff calls the continuum) that our evolution as a species has designed us to meet in order to achieve optimal physical, mental, and emotional development and adaptability.

  4. Cinderella effect - Wikipedia

    en.wikipedia.org/wiki/Cinderella_effect

    Evolutionary psychologists Martin Daly and Margo Wilson propose that the Cinderella effect is a direct consequence of the modern evolutionary theory of inclusive fitness, especially parental investment theory. They argue that human child rearing is so prolonged and costly that "a parental psychology shaped by natural selection is unlikely to be ...

  5. Parental investment - Wikipedia

    en.wikipedia.org/wiki/Parental_investment

    Sexual selection is an evolutionary concept that has been used to explain why, in some species, male and female individuals behave differently in selecting mates. In 1930, Ronald Fisher wrote The Genetical Theory of Natural Selection, [3] in which he introduced the modern concept of parental investment, introduced the sexy son hypothesis, and introduced Fisher's principle.

  6. Evolutionary developmental psychology - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_developmental...

    Mainstream evolutionary psychology grew out of earlier movements which applied the principles of evolutionary biology to understand the mind and behavior such as sociobiology, ethology, and behavioral ecology, [5] differing from these earlier approaches by focusing on identifying psychological adaptations rather than adaptive behavior. [20]

  7. Theoretical foundations of evolutionary psychology - Wikipedia

    en.wikipedia.org/wiki/Theoretical_foundations_of...

    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. [1]

  8. Alloparenting - Wikipedia

    en.wikipedia.org/wiki/Alloparenting

    In such cases, the alloparent and the offspring share a degree of relatedness (r (coefficient of relatedness) > 0); so kin selection is often involved in the evolution of the behaviour. [ 15 ] [ 16 ] Use of the term non-descendant young, as opposed to non-related young is therefore an important distinction in the definition of alloparenting.

  9. Parent–offspring conflict - Wikipedia

    en.wikipedia.org/wiki/Parent–offspring_conflict

    It is used to describe the evolutionary conflict arising from differences in optimal parental investment (PI) in an offspring from the standpoint of the parent and the offspring. PI is any investment by the parent in an individual offspring that decreases the parent's ability to invest in other offspring, while the selected offspring's chance ...
