Verified step by step guidance1
Darwin observed that the tortoises on the Galápagos Islands had different physical characteristics depending on the island they inhabited.
He noted that the shell shapes of the tortoises varied from one island to another.
Darwin concluded that these differences were adaptations to the specific environments and available resources on each island.
This observation supported his theory of natural selection, where organisms adapt to their environment over time.
The variation in shell shapes among the tortoises was a key example of how species could evolve distinct traits in response to different environmental pressures.
