What did the shape of the turtle shells indicate to Darwin?
The shape of turtle shells indicated to Darwin that different species of tortoises had adapted to their specific environments. For instance, he observed that the domed shells of tortoises from wetter regions allowed them to store water, while the saddle-backed shells of those from arid areas were better suited for reaching higher vegetation. This variation supported his theory of natural selection, illustrating how species evolve traits that enhance their survival in particular habitats.

How did tortoises varied from island to island?
Tortoises varied from island to island primarily due to differences in environmental conditions, such as food availability and climate. These variations led to distinct adaptations, such as differences in shell shape and size; for instance, some islands had tortoises with dome-shaped shells suited for dense vegetation, while others featured saddle-backed shells that allowed for easier grazing on higher vegetation. These adaptations are examples of natural selection acting on isolated populations, contributing to the diversity of species observed in the Galápagos Islands.

What do giant tortoises look like?
Claws and JawsThe giant tortoise boasts five front claws and four claws on the back. They help the tortoise navigate through sometimes rugged terrain. When walking, the front limbs and claws usually appear to be turned inward facing one another. Complementing his primarily vegetarian diet, the giant tortoise's jaw is toothless.ShellsAll tortoises are shielded by the protective covering of their shells. Giant tortoises have either a round, dome-shaped shell or a saddle-back shell. Tortoises with a dome-shaped shell grow to be larger than the saddle-backed variety. Historically, they have always lived on islands with a lot of rainfall where vegetation is plentiful, so this may also explain their larger size. Saddle-backed tortoises developed their saddle-backed shell shape because of a biological adaptation that allowed them to extend their necks further to reach food. They tend to live on islands with less rainfall and dryer climates.ScalesA closer look at a giant tortoise will reveal an appearance that is somewhat reminiscent of dinosaurs or crocodiles. Giant tortoises have thick scales all over their limbs, neck and pointed head. Their limbs vary from dark grey to black in color. The thickness of their skin helps protect them from the sun, but their hard shell is still very important for protecting their soft endoskeletons.
