Are the Galapagos Islands similar to each other? The individual Galapagos Islands are all similar to each other. Malthus argued that human populations grow faster than their resources. Lamarck was one of the first scientists to propose that species evolve by natural selection.
What are some differences between the Galapagos Islands turtles? Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with “saddleback” shells and long necks.
What part of turtles are different depending on the island you are on in the Galapagos? Minor differences distinguish the Galápagos tortoises on each island.

Tortoises from Pinzn Island (formerly Duncan Island) are “saddle-backed,” meaning that their shells rise in the front, like a saddle.
