Which of the following statements about the Galápagos Islands tortoises did Charles Darwin learn that contributed to his theory of natural selection?
A
The tortoises were all identical across the islands, showing no variation.

The tortoises could fly short distances between islands.
C
The tortoises were the only herbivores on the islands.
D

Verified step by step guidance1
Identify the key concept: Charles Darwin's observations of the Galápagos Islands tortoises contributed to his theory of natural selection.
Understand that natural selection involves variation among individuals in a population, which can lead to different survival and reproduction rates.
Consider the options provided: identical tortoises, flying tortoises, herbivorous tortoises, and tortoises with different shell shapes.
Evaluate each statement: identical tortoises would not demonstrate variation, flying tortoises are biologically implausible, and being herbivores does not directly relate to natural selection.
Recognize that the statement about different shell shapes among tortoises on different islands illustrates variation, which is a key component of natural selection.
