👤 whose
Whose research first showed that bird beaks can evolve rapidly under environmental pressure?
Quick Answer
Peter and Rosemary Grant are famous for this work on Darwin’s finches. Their long-term studies in the Galápagos showed beak evolution can occur over just a few generations.
The Full Story
Peter and Rosemary Grant carried out decades of fieldwork on Darwin’s finches in the Galápagos Islands. Their research showed that droughts and changes in food supply can quickly favor birds with certain beak sizes and shapes. This was one of the strongest real-world demonstrations of natural selection in action. Their studies gave evolution a timescale that could be observed directly.
Key Facts
1.Long-term finch studies began in the 1970s
2.Beak traits changed measurably over generations
3.The work became a classic case of natural selection
