Sea snakes are a venomous family of snakes that inhabit marine environments for most of

their lives. Unlike land-dwelling, terrestrial snakes, they have a paddle-like tail. The paddle shape allows them to swim more easily. Which of the following explains the process that would have resulted in these snakes having this type of tail.

• An ancestor of modern sea snakes likely had a mutation that caused its tail to be more flattened. This mutation provided a survival advantage that allowed the trait to be passed onto future generations. In future generations, sea snakes with flat tails were also better able to survive, leading to the evolution of flat tails in sea snakes through the process of natural selection.

• The snakes tail is random and the process is random.
