Convergent Evolution 3

Convergent evolution is the driven by natural selection, the implement for evolution. maturation is the change in gene frequencies deep bug out a population. This requires individuals within a population to have assorted phenotypic expressions of traits. few of these variations of traits grant more(prenominal) reproductive opportunities to those that possess them; for guinea pig they may be stronger, faster, or more attractive to the turnabout sex. If those traits atomic number 18 then inherited by the offspring, they lead generate more common within the population. On the some other hand, some variations of traits go away bowdlerize/eliminate reproductive success for those that possess them and those genes will diminish in the population, as a whole, through time. This interaction between genes and the environment results in the changes in gene frequence within a population. In geographically separate but resembling environments, evolution may be driven by a like selective agent. For example, in desert ecosystems around the world, ignite is a ubiquitous, strong, selective agent that is capable of killing individuals that do not possess adaptations to its power (thus eliminating their genes from the population and favoring the spread of other genes that allow for survival at high temperatures). The possible adaptations to cacoethes ar limited by physiological realities, ancestral histories, and carnal laws. A desert rodent can not stick up by ignoring the physical law that its protoplasm will grumose at a high enough temperature. It can aestivate, require crepuscular/nocturnal, or resort to subterranean life. There argon a limited number of adaptive solutions to any premise selective agent. This leads to convergence. That is, evolution by natural selection, pushing the evolutionary paths of unrelated species in similar directions. The limited solutions to selective agents oft lead to convergence of a trait. Consider the sim ilarities amongst unrelated aquatic life for! ms (e.g. a penguin, a fish, and a dolphin)... If you want to trail a full essay, order it on our website: OrderCustomPaper.com
