Deserts can be found at 30° N and 30° S of the equator. If you visited the deserts in both regions you would see that the dominant plants look very similar. This is MOST likely the result of:
A)common ancestry.
B)convergent evolution.
C)adaptive radiation.
D)biome specialization.

Question

Quizplus · Accepted Answer

The fact that the dominant plants in deserts at 30° N and 30° S of the equator look very similar suggests that they have evolved similar traits as a result of convergent evolution. While these plants may not share a common ancestry, they may have adapted to similar environmental pressures and evolved similar traits independently. Adaptive radiation and biome specialization are unlikely to be responsible for the similarities seen in these desert plant communities.
