Question

The original population of brown spotted deer declined drastically after their forest habitat was flooded. After frantic efforts over three decades by the forest authorities to revive the dwindling population, it did bounce back. Now the deer population is as huge as it was three decades ago, but it shows a decreased amount of genetic variations. Which factor could be responsible for this microevolution?

Answer 1

Evolutionary bottleneck. The current population is descended from the few deer that existed at the population's lowest level.

Answer 2

A. Convergent evolution produces organisms with different adaptations but common ancestry, whereas adaptive radiation produces organisms with similar adaptations but different ancestry.
