Darwin's Theory Of Natural Selection

oList and describe the evidence for phylogeny, which was presented by Darwin
subjective Selection
States that favourable variations on species ar selected and harmful ones argon eliminated according to the ability to pass in the environment.
The four master(prenominal) points outlining natural selection are
oNo species has identical members
oIn every generation there are number that do not reach maturity, and as a result, the characteristics of these members are not carried on as they do not reproduce
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 more apparent in a species

E.G.
Darwin observed (while on his visit to Australia)crows like 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 European rabbit both in size and behaviour(2)

Natural selection also leads to the evolution of new species. For example; by studying the skeletal and brawny structure in the Hawaiian honeycreeper, scientists were able to find similarities and could swan that the current 23 species of honeycreepers all evolved from one ancestral species.



This is a grapheme of divergent evolution called adaptive radiation, which occurs when a species inhibits a habitat where there are few competing species.
The other type of evolution is convergent evolution, which is where dickens seemingly unrelated species move more and more alike in tell to survive in similar environments.

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, order it on our website: Ordercustompaper.com
