How can geography lead to reproductive isolation?
A. Some populations may have a milder habitat than other populations.
B. A physical barrier may arise and separate a population, preventing interbreeding.
C. Extremes of temperatures may reduce the breeding opportunities for some.
D. Subspecies may choose to occupy different areas for competitive reasons.
When a species fails to produce any more descendants, it is said to
A. be divergent.
B. have speciated.
C. have become isolated.
D. be extinct.
Under which circumstance could a well-adapted species become poorly adapted?
A. when the environment changes faster than new adaptations can evolve
B. when a well-adapted species becomes reproductively isolated
C. when a species can no longer interbreed and produce fertile offspring
D. when a successful population exceeds their carrying capacity in the environment
