Components of natural selection.
1.Much of the research on evolution by natural selection done since Darwin relies on a solid and ever-expanding understanding of the process of genetic transmission. 2.Evolution by natural selection is the inevitable consequence of three simple conditions: variation, inheritance, and differential reproductive success.
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. For example, some beetles are green and some are11 jul 2011 ... Natural selection. There are two major components to the theory.
