Evolution Of Organisms Derives From Variation And The Process Of Natural Selection

The evolution of organisms derives from variation and the process of natural selection. Variation is the diversity within a population. The most common source of genetic variation in organisms is from mutations, which are types made of the genetic material. Sections of DNA may be repeated, deleted, or moved by the process of mutation. Mutations are very common and occur throughout the genome. This establishes a great diversity between organisms of the same species and makes each being unique. Similar to how all humans are accepted to be genetically unique, all species are made of organisms that each is composed of its own, different genetic material. Another source of genetic variation comes from recombination and crossing over. Recombination
