Darwin's Theory Of Natural Selection

oList and describe the evidence for phylogeny, which was presented by Darwin subjective Selection States that comfortable variations on species ar selected and harmful ones argon eliminated according to the baron to pass in the environment. The four master(prenominal) points outlining natural selection ar oNo species has identical members oIn every generation there atomic number 18 cast that do not reach maturity, and as a result, the characteristics of these members argon not carried on as they do not sick o thriving variations allow for the adaptation of the stronger organisms to occur (survival of the fittest) oFavourable variations are passed on to offspring to allow for that trait to scram to a greater extent apparent in a species E.G. Darwin observed (while on his ensure to Australia)crows kindred our English jackdaws were not uncommon, and another birdie something like a magpie. He also saw a rat-kangaroo (a potoroo) which he compared to a Euro pean rabbit both in size of it and behaviour(2) Natural selection also leads to the maturation of innovative species. For example; by studying the skeletal and brawny coordinate in the Hawaiian honeycreeper, scientists were able to find similarities and could swan that the ongoing 23 species of honeycreepers all evolved from one ancestral species.

This is a lineament of divergent evolution called adaptive radiation, which occurs when a species inhibits a home ground where there are few competing species. The other type of evolution is convergent evolution, which is where dickens controlmingly unrelated species move much and more alike in tell to survive in similar env ironments. The final type of evolution is! coevolution. This is where two or more species that are in close fundamental interaction with each other change together, such as predators and their prey, or between plants and the animals that pollinate them. E.G. In tropical regions bats see flowers to eat nectar. The fur on the bats face and neck picks up pollen, which the bat transfers to...If you want to get a full essay, ordain it on our website: OrderEssay.net
