Question

Common in Darwin’s finches and Australian marsupials is:

• A. They are all extinct.
• B. They show adaptive radiation.
• C. They have homologous organs.
• D. They are all found in South America.

Hint:

Remember that when more than one adaptive radiation occurs in an isolated geographical area (representing different ancestral stocks), it results in convergent evolution.
For example, the placental wolf and the Tasmanian wolf (marsupial) show striking similarities due to convergent evolution, though each arose from its own separate adaptive radiation.

Answer 1

The Correct Option is B

Step 1: Adaptive radiation.
Both Darwin's finches (Galapagos) and Australian marsupials independently diversified from a common ancestor to fill different ecological niches.
Answer: Show adaptive radiation
