Which scenario best illustrates peripatric speciation?
Show answer and explanation
Correct answer: A small group colonizing a remote island and diverging from the mainland
Peripatric speciation involves a small, peripheral population becoming isolated (such as on an island), leading to rapid genetic divergence from the mainland population — a special case of allopatric speciation.
