Question

Finches living on the Galápagos Islands were critical for Darwin to develop his ideas. What key observation did he make about finches.

A: the finches’ feathers were structurally different to allow them to fly at different heights and speeds, depending on their local environment.
B: the finches’ feathers were colored differently, providing camouflage within their unique environment
C: the finches’ beaks were uniquely adapted as tools for them to eat the food that was available to them
D: the finches’ beaks we’re colored differently, providing camouflage within their unique environment

Answer 1

The finches would beaks we're colored differently, providing camouflage within their unique environment.

Option (d);

EXPLANATION:

Galápagos Islands are near the South America coast. Finches migrated from there to these islands. Darwin observed that finches were different on every island he visited. He observed that finches had different colored beaks.

Along with the difference in color, he also observed that the available food was different on different islands.Seeds were varying in sizes in different islands. So, finches adapted to their respective environments for different kinds of food available and their survival became easy.
