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 scenario describes a deer population split by a geographic barrier (canyon), leading to separate adaptations and inability to interbreed (new species). Geographic isolation is the initial cause here. Reproductive isolation is the end result, not the starting mechanism. Natural selection and adaptation are part of the process but not the specific primary driver described.

Answer:

A. Speciation by Geographic Isolation
