Parent–offspring conflict
Is this soap opera or science? It can be both, but in evolutionary biology it refers to the subtly different ways natural selection acts on genes expressed in parents and their offspring. To give a concrete example, consider a parent with two offspring: other things being equal, the parent is likely to be under natural selection to give equal amounts of food to each of its young. But natural se...

متن کاملExperimental evidence for offspring learning in parent-offspring communication.
The offspring of birds and mammals solicit food from their parents by a combination of movements and vocalizations that have come to be known collectively as 'begging'. Recently, begging has most often been viewed as an honest signal of offspring need. Yet, if offspring learn to adjust their begging efforts to the level that rewards them most, begging intensities may also reflect offsprings' pa...
متن کاملAntagonistic Parent-Offspring Co-Adaptation
BACKGROUND In species across taxa, offspring have means to influence parental investment (PI). PI thus evolves as an interacting phenotype and indirect genetic effects may strongly affect the co-evolutionary dynamics of offspring and parental behaviors. Evolutionary theory focused on explaining how exaggerated offspring solicitation can be understood as resolution of parent-offspring conflict, ...
متن کاملParent–Offspring Conflict in Mate Preferences
Prevailing evolutionary approaches to human mating have largely ignored the fact that mating decisions are heavily influenced by parents and other kin. This is significant because parents and children often have conflicting mate preferences. We provide a brief review of how parents have influenced their children’s mating behavior across cultures and throughout history. Then, by drawing on evolu...
