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.
It allows scientists to explore new explanations for observations.
The sunlight provides energy for the plants to grow. <span>Since it is a closed system, no water would be lost, so it is not necessary to add extra water. </span>
Answer:
Genetic drift may occur when a small group of individuals colonize a new habitat. True or false. Two populations that have overlapping ranges can remain reproductively isolated through behavioral isolation or temporal isolation from each other.
