It suggests we should be cautious also about popular evolutionary ideas of our own time. According to Wynne-Edwards, this limitation ultimately meant that group selection functioned to keep populations in check, safeguarding them against excessive growth by influencing the evolution of species’ reproductive rates. This chapter was originally published in The New Palgrave Dictionary of Economics, 2nd edition, 2008. Acad. 2003. Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes (genetic compositions), by means of natural or artificial controlling factors. Natural selection is a pressure that causes groups of organisms to change over time. Show more. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. Proc. Many evolutionary biologists agreed that adaptation through selection at the level of the individual and the gene was of greater consequence than selection at the group level. …selection sometimes operates at the level of groups and hence that there can be adaptive features that benefit the group at the expense of the individual. Our editors will review what you’ve submitted and determine whether to revise the article. It suggests we should be cautious also about popular evolutionary ideas of our own time. Sober [38, p. 836] describes the distinction this way: ‘For the contextual approach, “group selection” means that an individual's fitness is affected by the kind of group the individual occupies. Biological evolution is not defined as simply change over time. Group selection refers to pressures that lead to group adaptations and more altruistic traits. The theory of evolution by natural selection was proposed by Charles Darwin and Alfred Updated: 21 June 2017. According to biologists, group-level adaptations can evolve only by a process of natural selection at the group level. Corrections? © 2020 Springer Nature Switzerland AG.

Group selection among alternative evolutionarily stable strategies. their genomes are blasted to smithereens), groups can be vehicles of replicators (genes) as well. But toward the middle of that century, following the rise of neo-Darwinism, in which Darwin’s theory of natural selection was synthesized with genetics (the modern evolutionary synthesis), the idea that selection acted on groups was largely dismissed. At the ground level of common sense, there arealligators, ants, beetles, marmots, moles, mushrooms, ostriches,roses, trees, and whales. The stronger the selective pressure or the selection event the fewer individuals make it through the sieve of natural selection. Wynne-Edwards. ‘Group selection’ is the biological term for the possibility that a characteristic that is beneficial to the group but possibly costly to the individual is evolutionarily successful. In the early 20th century, Darwin’s observations of group behaviour were explored by others in studies that focused on the evolution of certain physical traits and behaviours that appear to benefit social groups.

Williams, and British evolutionary biologist Richard Dawkins. I. Group selection will promote the gene for altruism, while individual selection will tend to eliminate it. Although logically possible, it is generally viewed with scepticism by biologists. For the Price approach, “group selection” means that there is variation in the fitnesses of groups’. Wynne-Edwards’s idea, however, contradicted emerging ideas associated with the neo-Darwinian synthesis, and many of his examples were based on individuals or on noncohesive groups. By Steven N.
