Which evidence of evolution related to Darwin's finches?
- Evidences from comparative anatomy
- Evidences from embryology
- Evidences from biogeographical distribution
- Evidences from palaeontological
Answer
(3) Evidences from biogeographical distribution
Solution
As per NCERT, during his journey Darwin went to the Galapagos Islands and observed a variety of small black birds (Darwin's finches); from the original seed-eating finch many varieties with altered beaks evolved on the islands.
∵ The study deals with the geographical distribution of species on isolated islands and their divergence from a mainland ancestor (adaptive radiation),
∴ Darwin's finches provide evidence from biogeographical distribution.
