WHAT IS GEOGRAPHICAL ISOLATION?

And I don't need Google answer I already have it.​

Answer 1

Answer:

Geographic isolation of a group of organisms which eventually stops gene flow from other groups of same species. Thus isolated group evolves by accumulating new mutations not to be found in members of related groups.

Answer 2

Step-by-step explanation:

when two or more idividual seperate and go on to different places far from each other then the further generations inherit different variations due to which when they meet several years later they look very different. This is a way how evolution occured.

Now let us look at an example

suppose you and your brother have a fight and you move to some different place from india(supposingly) to africa (if your mom allows you to do so and you get a nice scolding if not. Or might be if you were to live in the time of nomads)

So after many many generations if both of your's successors meet they will be really really different from each other.

your's will be really black in skin color and his will be wheatish in color. And this was what geographical isolation is and how it works
