Evidence for Evolution Evolution is defined as the transplant in genetic material of a population of organisms from unmatched coevals to the next. every(prenominal) living organisms are evolved from a crude ancestor. in that respect are many opposite pillowcases of depict for evolution, including biogeography, homology, and fossil records. These polar types of evidence, in their own way, sharpen that ripe species are descendents from inherited species with variations in their genes. The idea that organisms are geographically distri plainlyed throughout the human being is known as biogeography. trustworthy organisms that are in extreme locations seem to be nearly related. This is due to continental ball up and the separation of Pangaea, which was at once a large continent that stony-broke up into different landmasses. For example, the ostrich and the electromagnetic unit closely agree each other and may have been in the aforementioned(prenominal) species mill ions of years ago, but they were separated and the ostrich became native to Africa and the emu became native to Australia. two adapted to their environments overtime and eventually evolved into 2 different species. Continental drift of the landmasses was a factor that contributed to this. This is how biogeography supports the possibility of evolution. Another type of evidence for evolution is homology.
Homology is the characteristics of related species share similarity in structure but differences in function. The homological structures of a whales fin, a human arm, a bats wing, and a cats leg show similarity in bone structure, signifi abidece that they ! have the same(p) arranging from the shoulder to the tips of the digits. However, these forelimbs of each mammal have different functions (i.e., swimming, lifting, flying, and walking). Homologies can also be find at the molecular level. All living organisms have the same genetic lyric for deoxyribonucleic acid and RNA, which are cytosine, guanine, adenine (DNA and RNA), deoxythymidine monophosphate (DNA) and uracil (RNA). The genetic language is nearly universal, meaning that all...If you privation to get a wax essay, order it on our website: OrderCustomPaper.com
