Why does geographic isolation cause speciation?

Biology
2 answers:
zimovet [89]3 years ago
3 0

Answer:

A. It allows two populations to evolve separately.

Explanation:

Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.

We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.

B is incorrect because it doesn’t apply.
