The central idea here is that when populations are geographically separated, they will diverge from one another, both in the way they look and genetically. These changes might occur by natural selection or by random chance (i.e., genetic drift), and in both cases result in reproductive isolation.

Answer:

1.genetic drift is variation in the relative frequency of different genotype in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

2. natural selection is when the species of a certain animal are able to cope and survive according to its environment and those species that cannot survive die and become extinct

3. reproductive isolation is  a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation

4.speciation is the formation of new and distinct species in the course of evolution.

5.gene  is the basic physical and functional unit of heredity
