Question

Which of the following is an example of natural selection?

A. Hummingbirds drinking nectar from a plant.

B. Whales and dolphins swimming to the water’s surface to breathe.

C. Sloths making their homes high in trees to protect themselves from predators.

D. Brown-colored lizards surviving and reproducing because they are better able to camouflage themselves from predators.

Answer 1

D. Brown colored lizards surviving and reproducing because they are better able to camouflage themselves from predators.

Step-by-step explanation:

While the other options have the potential to be influenced by the environment, answer D is the only one that explicitly says that a certain trait (brown coloring) in a population (lizards) will help them to survive and reproduce more as a direct result of that trait.

Answer 2

A) Hummingbirds drinking nectar from a plant.

Step-by-step explanation:

Here are some examples of natural selection: In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
