Darwin explained the differences in shell shapes of tortoises from Hood Island and Isabel Island as adaptations to their specific environments. The tortoises from Hood Island, which had sparse vegetation, evolved to have saddle-shaped shells that allowed them to stretch their necks to reach higher plants. In contrast, the tortoises from Isabel Island, where vegetation was more abundant, developed dome-shaped shells that provided better protection and support for their feeding habits. This variation highlighted the role of natural selection in shaping species based on their ecological niches.
Darwin proposed that the differences in shell shape of tortoises from Hood Island and Isabela Island were adaptations to their respective environments. He suggested that tortoises on Hood Island had developed dome-shaped shells to reach higher vegetation, while those on Isabela Island had saddle-shaped shells for easier access to lower vegetation. This variation in shell shape helped the tortoises better survive and reproduce in their specific habitats.
turtles have shells....
Darwin's studies on the Galapagos Islands focused on the unique species of finches and tortoises found there. These observations of variations in traits among similar species contributed to the development of his theory of evolution by natural selection. Darwin's research in the Galapagos played a crucial role in shaping his ideas on the origin of species.
dunno :) hope i helped! lol i think it was the galapagos islands :)
Darwin noticed that different, yet related, animal species often occupied different habitats in the same area.
he didnt lol
he didnt lol
Adaption to the environment is how Darwin explained the differences in shell shape. Hood Island tortoises needed to reach up with their necks further for food than the Isabela Island tortoises.

The Galapagos finches and the Galapagos tortoises.
Variation in length of the tortoises' necks
tortoises
turtles have shells....
On his return trip to England, Darwin thought about the tortoises and their vegetation compared to the height of the animals.
Darwin learned that there were different shaped backs of the tortoises, some had arc shaped or straight. The other thing the tortoises had is long or short necks. There were varieties of island and on every island there were different tortoises.
