Question

a student has written a paper about a deer population that was separated when a canyon developed between members of the group. in her paper, she showed that the two groups adapted differently and can no longer interbreed. what would be the best title for her paper?
○ speciation by geographic isolation
○ speciation by reproductive isolation
○ how natural selection creates species
○ how adaptation creates species

Explanation:

The problem is about a deer population separated by a canyon (geographic barrier), leading to different adaptations and inability to interbreed (speciation). Geographic isolation causes this, while reproductive isolation is the result, not the cause here. The other options focus on natural selection or adaptation generally, not the geographic separation. So the best title is about speciation by geographic isolation.

Answer:

A. Speciation by Geographic Isolation
