alleryThe 14 species of finches that Darwin observed on the Galapagos Islands are a classic example of:
AConvergent evolution across distant taxa
BAdaptive radiation (one ancestor, many niches)
CGenetic drift (random allele changes)
DVestigial organ formation in birds
Answer & Solution
Correct answer: B. Adaptive radiation (one ancestor, many niches)
**Galapagos finches:** 14 species evolved from a single mainland ancestor, each adapted to a different niche (beak shapes for different food types).
The textbook example of ADAPTIVE RADIATION via allopatric speciation.
