Question

scientist collects wild rabbits that live at sea level and moves them to the mountains. One year later, the scientist discovers that the same rabbits have larger lungs, which help them breathe the thin mountain air. The scientist returns the rabbits to sea level. Will the offspring of these rabbits have larger than normal lungs? Explain why or why not.
Thanks for help :)

Answer 1

No, the offspring will not have larger lungs. Their environment, not their genes, produced the larger lungs of the rabbits kept in the mountains. Only traits that are controlled by genes can be acted upon by natural selection and passed on to their offspring.
