Understanding Evolution: A Simple and Easy Illustration by Adam Chandler on Saturday‚ June 23‚ 2012 at 5:54am Many people don’t understand what evolution is‚ and how it happens. Therefore‚ some of them might reject it based on not knowing what it is‚ or based on a wrong understanding of it. Because of that‚ I find it my duty to make an easy to understand illustration of evolution‚ as I believe I understand it well. I’ll try to make this illustration as easy as possible‚ and in many places‚ oversimplified

prezygotic isolating mechanism is ecological isolation‚ also referred to as habitat isolation. Ecological isolation prevents different species that live in the same territory but different habitats from interbreeding. These species are referred to as sympatric species since they occur in the same territories. Individuals mate in their preferred habitat‚ and therefore do not meet individuals of other species with different ecological preferences. An example of ecological isolation occurs within the Rana

parents were found to be first cousins‚ which is unusual for members of our species to mate when that closely related. One of the potential reasons for why this inbreeding could have happened is the geographical isolation. The community is in essence allopatric to the neighboring towns since that sort of travel is unfeasible to their lifestyle. It is unlikely that this family is a “genetic throwback” or a “missing link” and it was almost offensive to the family to act as if they were in reverse evolution

Biodiversity From Wikipedia‚ the free encyclopedia Coral reefs are amongst the most diverse ecosystems on earth. Rainforests are an example of biodiversity on the planet and typically possess a great deal of species diversity. This is the Gambia River in Senegal’s Niokolo-Koba National Park. Biodiversity is the degree of variation of life.[1] It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation‚ ecosystem variation‚ or species variation
