Genetic drift is a change in allele frequency in a population due to a random selection of certain genesOftentimes mutations within the DNA can have no effect on the fitness of an organismThese changes in genetics can increase or decrease in a population simply due to chance.

. Biogeography refers to the distribution of various species and ecosystems geographically and throughout geological time and space. The environment is the external conditions resources stimuli etc with which an organism interacts. Natural selection is the result of the interactions between genetic variations in a population and the environment. It means making a copy a likeness and thereby providing for the continued existence of species.

Biogeography is often studied in the context of ecological and historical factors which have shaped the geographical distribution of organisms over time. Reproduction is one of the most important concepts in biology. The genetic variations that arise in a population happen by chance but the process of natural selection does not. The theory of natural selection was first founded by Charles Darwin.

The process of natural selection is important and is a driving force for evolution. Reproduction process by which organisms replicate themselves. Learn more about the process of reproduction in this article. Genetic variation is important to the processes of natural selection and biological evolution.

The meaning of NATURAL SELECTION is a natural process that results in the survival and reproductive success of individuals or groups best adjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment.
