The social selection alternative to sexual selection.
Social selection offers an alternative to sexual selection by reversing its logic. Social selection starts with offspring production and works back to mating, and starts with behavioural dynamics and works up to gene pool dynamics. In social selection, courtship can potentially be deduced as a negotiation, leading to an optimal allocation of tasks during offspring rearing. Ornaments facilitate ...
متن کاملSexual selection is a form of social selection.
Social selection influences the evolution of weapons, ornaments and behaviour in both males and females. Thus, social interactions in both sexual and non-sexual contexts can have a powerful influence on the evolution of traits that would otherwise appear to be detrimental to survival. Although clearly outlined by West-Eberhard in the early 1980s, the idea that social selection is a comprehensiv...
متن کاملSexual Selection, Social Competition, and Evolution*
Social behavior holds a special position among natural phenomena in relation to the Darwinian theory of organic evolution. When individuals of the same species live in close proximity they compete directly for essential resources. And intraspecific reproductive competition is the cornerstone of the theory of evolution by natural selection. Thus the drama of what G. E. Hutchinson (1965) referred...
متن کاملReproductive social behavior: cooperative games to replace sexual selection.
Theories about sexual selection can be traced back to Darwin in 1871. He proposed that males fertilize as many females as possible with inexpensive sperm, whereas females, with a limited supply of large eggs, select the genetically highest quality males to endow their offspring with superior capabilities. Since its proposal, problems with this narrative have continued to accumulate, and it is o...
متن کاملThe sexual selection continuum.
The evolution of mate choice for genetic benefits has become the tale of two hypotheses: Fisher's 'run-away' and 'good genes', or viability indicators. These hypotheses are often pitted against each other as alternatives, with evidence that attractive males sire more viable offspring interpreted as support for good genes and with a negative or null relationship between mating success of sons an...
