Question

Explain the following term:

Darwin’s finches

Answer 1

Darwin’s finches are a group of about 20 related species of small birds found on the Galapagos Islands, which Charles Darwin studied during his visit on the HMS Beagle in 1835. These finches are remarkable because:

• They all belong to the same family of seed-eating birds but have diversified into different species with varying beak shapes and sizes.
• Their beak variations correspond to different feeding habits (such as seed-eating or insect-eating) and adapt to different environmental conditions across the Galapagos Islands.
• Despite inhabiting similar habitats on different islands, the finches differ significantly from mainland American finches, though they share a related ancestor on the South American continent.
