Question

What type of barrier affected the genetic variation and diversity of Darwin’s finches on the Galápagos Islands?

geographic isolation
allopatric speciation
temporal isolation
behavioral isolation

Answer 1

What do you think it is?

Answer 2

Could it be geographic?

Answer 3

what is the fundamental difference between allopatric speciation and geographic isolation?

Answer 4

Isn't allopatric the result of geographic?

Answer 5

yup, and your correct it is geographic isolation :) But do you understand why?

Answer 6

I'm not entirely sure if I understand

Answer 7

Allopathic is is speciation that occurs when biological populations of the same species become vicariant, or isolated from each other to an extent that prevents or interferes with genetic interchange

Temporal is evolutionary mechanism that keeps individuals of different species from interbreeding, even if they live in the same environment.

Behavioral biological features of organisms that prevent species from reproducing and having offspring

And lastly Geographical occurs when a population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species
