Parent–offspring conflict (POC) is an expression coined in 1974 by Robert Trivers. 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 ...
Patterns developed the idea of a "counter-blitz", a blitzkrieg in reverse, with numerous attacks followed by withdrawals to the rear. The aim was to confuse the enemy by presenting no apparent strategy, reveal the enemy's intentions through the strength of the response, and present a misleading picture of the defender's own actions in order to ...
Robert Ludlow "Bob" Trivers (/ ˈ t r ɪ v ər z /; born February 19, 1943) is an American evolutionary biologist and sociobiologist.Trivers proposed the theories of reciprocal altruism (1971), parental investment (1972), facultative sex ratio determination (1973), and parent–offspring conflict (1974).
Conflict theories are perspectives in political philosophy and sociology which argue that individuals and groups (social classes) within society interact on the basis of conflict rather than agreement, while also emphasizing social psychology, historical materialism, power dynamics, and their roles in creating power structures, social movements, and social arrangements within a society.
However, conflict among genes in the same genome may arise both in events related to reproduction (a selfish gene may "cheat" and increase its own presence in gametes or offspring above the expected according to fair Mendelian segregation and fair gametogenesis) and altruism (genes in the same genome may disagree on how to value other organisms ...
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution.It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
One theory suggesting a mechanism that could lead to the evolution of co-operation is the "market effect" as suggested by Noe and Hammerstein. [22] The mechanism relies on the fact that in many situations there exists a trade-off between efficiency obtaining a desired resource and the amount of resources one can actively obtain.
By stotting (also called pronking), a springbok (Antidorcas marsupialis) signals honestly to predators that it is young, fit, and not worth chasing.. Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species.
