Questions - Essay ExampleHe was interested by the fact that the species were various. He concluded that the species were different because they dwelled in different environmentsThe concept of natural selection explains how species evolves and genes are passed from generation to the next. Darwin argues that a species can develop a functional advantage in that the species grows wing and learn to fly. He asserts that the offspring will inherit that advantage and pass it on to the offsprings. On the other hand, those who are disadvantaged but members of the same species will gradually pause and live the superior members of the same species. Species preserve the functional advantage and that help the species to compete in the harsh environment.Darwins explanation of the origin of species in 1859 was criticized by Christians because they believed in Gods creation for six days. The natural selection was received with hostility because his ideas were not with alignment with biblical descri ptions on how Adam and even were created. In addition, after the arrival of Darwins theory, scientists conflicted and they did not support the idea of evolution.A vector is a vehicle that transfers genetical materials to a target cell. The deduction of vectors is to pass on the genes to the intended cell. For evolution to take place there has to be passage of genetic materials from one species to the other. Hence the vector facilitates the movement of biologic traits from one generation to the other.Equilibrium is a principle that explains that genes remain the same from one generation to the other without any disturbing factor. If the situation remains unalterable then there will be evolution stability. However this can be affected by forces such as mutations, natural selection, non random mating, genetic drift and gene flow.Isolation can promote genetic divergence through mechanisms such as mutation, genetic drift and natural selection. Allopathic speciation is a
