Question

question 6 of 10
why would a rough, steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat?
a. the mountain would isolate subgroups of the population.
b. the mountain has more resources.
c. the mountain would cause less fragmentation in the population.
d. the mountain has fewer niches.

Explanation:

Speciation is promoted by isolation. Steep, rough mountains can physically separate subgroups of a population, leading to genetic divergence over time and thus higher speciation rates. Grasslands are more open, allowing for greater gene - flow between populations. Mountains typically have more niches due to varied micro - habitats, and they cause more fragmentation. Resources are not the main factor in explaining the higher speciation rate here.

Answer:

A. The mountain would isolate subgroups of the population.
