Cryptic microevolution
WebNov 3, 2024 · The circumstances under which selection can change a quantitative trait are more stringent than is perhaps immediately apparent. One helpful way to think about this, devised in the context of artificial selection, is the breeder's equation (Lush, 1937).This states that change in a trait's mean value in a population is proportional to both the … WebThe study demonstrates microevolutionary consequences of natural selection. The population of medium ground finches, Geospiza fortis, experienced size-selective mortality during a drought in 1976-1977; large birds with deep beaks survived better than small birds.
