While Charles Darwin was in Galapagos, he visited the islands of Floreana, Isabela, San Cristóbal, and Santiago only.

How did Darwin explain differences in shell shape of tortoises from Hood Island and Isabela Island?
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.
How did Darwin explain differences in shell shape of tortoises hood island and isabela island?
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.
Darwin concluded that organisms on the Galápagos Islands?
Darwin concluded that organisms on the Galápagos Islands showed variation from island to island, leading to his theory of natural selection as a mechanism for evolution. He observed unique adaptations in species such as finches and tortoises, which helped support his ideas on how species could change over time in response to their environment.
How did Darwin explain differences in she'll shapes of tortoises from hood island and Isabel's island?
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.
How did Darwin explain differences in shell of tortoises from hood island and isabela island?
he didnt lol
How did Darwin explain differences in shell shapes of tortoises from Hood Island and Isabela Island?
he didnt lol
Darwin observed that tortoises of the nearby islands belonged to the same species how might he have known?
Darwin likely recognized that the tortoises from different islands shared similar physical characteristics, such as shell shape and size, indicating a common ancestry. He also observed variations in these traits that corresponded to the distinct environments of each island, suggesting adaptation to local conditions. Additionally, the tortoises' similar behaviors and biological features would have pointed to their classification as the same species despite the observable differences.
What was Name of the island where Darwin observed finches?
The Galapagos Islands
What did Charles Darwin conclude based on the giant tortoises observed in the Galapagos Islands?
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.
Who observed variations in characteristics of animals and plants on the island of galapagos?
charles darwin
What did Darwin study on the Galapagos's islands?
Certain species, and how they differed from one island to another; in this case, specifically, finches and tortoises.
What accounts for the variation darwin observed amoung island species?
Darwin observed that island species often varied significantly from their mainland counterparts due to factors such as geographic isolation, differing environmental conditions, and limited gene flow. These conditions can lead to unique adaptations as species evolve to exploit specific niches. Additionally, the lack of predators and competitors on islands can result in different evolutionary pressures, allowing certain traits to flourish. This variation illustrates the principles of natural selection and adaptive radiation.
