Imagine an island inhabited by a large population of a certain kind of creature, let's call them furberts. Let's call our group of furberts "Population A." Now, imagine that a powerful hurricane picks up about half of the furberts (remember, you're imagining this) and blows them to another island. Let's call this group "Population AB." As everyone knows, furberts can't swim, so there's no way for the furberts in Population AB to get back to their old island. After a while furberts in Population AB are so changed from the furberts in Population A, they cannot interbreed.

i think it is C

Or A?

anonymous · Answer

I think C because i think it is explaining starting a new species

You can find the answer by defining the options.

Introgression is movement of a gene from one species to another. That happens when 2 species crossbreed, which is not the case here.

Retrogression is the opposite of progression. A species goes back to an earlier stage, a less complex level of development. Not the case here

Speciation is the event where a new species arises. This could be the one since the question says that population AB differs from population A after a while.

Migration is simply the movement of a species to another location. But it does not necessarily means that the species will become another species. 

Therefore I would say Speciation is the best answer :)
