What do you mean by natural selection , genetic drift and geographical...
Natural selection, any characteristic of an individual that allows it to survive to produce more offspring will eventually appear in every individual of the species, simply because those members will have more offspring.


Genetic Drift Defined

Populations of organisms are constantly changing and adapting to their environment. 

Genetic drift is when chance events cause changes in frequencies of alleles in a population. Alleles are the genetic variations in a population, and they are the driving force behind the evolution of that population.


Geographic isolation is a term that refers to a population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species.
