Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.

The excess of water and the waste metabolism products pass less into the urine and accumulate in the body.
