Question

The populations living on a rough, steep mountain would have a higher rate of speciation than this living in a large, open grassland because the mountain would ___. A. Show less habitat fragmentation B. Have less variety in the environment C. Have a wider range of environments D. Provide more natural resources

Answer 1

The correct answer is option C, that is, have a wider range of environments.  

It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.  

A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.
