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 paper describes a deer population split by a canyon (geographic barrier), leading to different adaptations and inability to interbreed (speciation). Geographic isolation is the initial cause of the split, which drives speciation. Other options are too broad: reproductive isolation is a result, not the cause here; natural selection and adaptation are processes but not the specific trigger described.

Answer:

Speciation by Geographic Isolation
