Question

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.

Answer 1

Which best explains this scenario?

A.
migration

B.
introgression

C.
retrogression

D.
speciation

Answer 2

@chica96 I wouldn't say it best explains it, but it is certainly and example of the biological species concept. The concept states that members of the same species can interbreed with offspring that can also produce viable offspring. This is why mules are not a new species, same for ligers etc.

So, with that in mind, what do you think?

Answer 3

I think it is D.

Answer 4

Is that right?

Answer 5

@mrdoldum are you there?

Answer 6

@chica96 You are right.

Answer 7

thank you for your help@mrdoldum!!!

Answer 8

@chica96 NP. It is actually allopatric speciation but I bet that is not covered in your class.

Answer 9

I passed my test by a thread because of you thank you.
