Charles Darwin became famous for his theory of natural selection. This theory suggests that a change in heritability traits takes place in a population over time. This is due to random mutations that occur in the genome of an individual organism, and offspring can inherit these mutations. This was defined as the key to evolution, this is because random mutations arise in the genome of an individual. Until the 19th century, the prevailing view in western societies was that differences between individuals of species were uninteresting departures from their platonic ideals of created kinds. In 1859, Charls Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation.

Human variation is the genetic difference both within and among populations. There are three main causes of human variation namely mutation, gene flow and sex. These causes combined make it very unlikely for any two humans to have the exact same genetic make ,even twins who develop from the same zygote have slightly deferent genetics due to mutation, gene flow and sex. Mutation effect DNA changes, gene flow is a cause of genetic variation from one population to another and sex is a source of gene combinations which all lead to a vast variation in human
