A perspective that suggests children are biologically predisposed to develop attachments with caregivers as a means of increasing the chances of their own survival.

This theory posits that because females have a higher obligatory investment in offspring (pregnancy and lactation), they will be more selective in mate choice, while males will compete for access to the fertile female.

Focuses on how individuals allocate resources to growth, reproduction, and survival strategies over their lifespan, influenced by how their ancestors maximized their fitness in face of environmental pressures.

The concept that behaviors that help unrelated individuals can be evolutionarily advantageous if there is an expectation that the favor will be returned in the future.

A form of natural selection that favors the reproductive success of an organism's relatives, even at a cost to the organism's own survival and reproduction.

A mode of natural selection where members of one biological sex choose mates of the other sex to mate with, and compete with members of the same sex for access to members of the opposite sex.

The rapid learning process that typically occurs early in life, where a young animal establishes a behavior pattern of recognition and attraction to another animal of its own kind or to an object (as an adopted parent).

Behaviors used by individuals to attract and secure mates. Different strategies may be used depending on environmental and individual factors, in alignment with maximizing reproductive success.

Competition between siblings for parental resources can be understood from an evolutionary perspective as each sibling aims to maximize their own chances of survival and reproductive success.

A reproductive system where members of the group assist in the raising of young that are not their own direct descendants, which can be advantageous for enhancing the survival of kin.

This suggests that animals engage in behaviors that are costly to themselves to demonstrate to potential mates that they have good genes, thus making them more attractive.

Competition within the same sex for access to mates. This can include aggression, displays of strength or skill, or other behaviors that would make an individual more likely to win a mate.

The ability to walk on two legs evolved in humans due to a variety of proposed benefits such as energy efficiency, freeing the hands for tool use, and better visual surveillance of the environment.

The cognitive ability to attribute mental states to oneself and others and to understand that others have beliefs, desires, intentions, and perspectives different from one's own. Evolutionarily, it can be linked to complex social interactions and survival within group settings.

From an evolutionary perspective, play may be seen as important for the development of valuable survival and social skills, such as hunting, fighting, or establishing social hierarchies.

The Grandmother Hypothesis suggests that the cessation of female fertility later in life can be beneficial from an evolutionary perspective, as post-reproductive women can aid in the survival of their kin.

The evolutionary perspective suggests that humans may favor juvenile features because they evoke nurturing responses, aiding in survival of youth and promoting caregiving behavior among adults.

The formation of a long-term partnership between two individuals for purposes beyond mating, which can provide advantages in raising offspring due to cooperative caregiving and shared resource allocation.

The increase in cognitive complexity and problem-solving ability in human evolution can be seen as an adaptive response to changing and complex social and environmental challenges.
