Darwin's concept of evolution "the theory of decent with modification through variation and natural selection" can best be demonstrated by which of the following examples? a. A giraffe stretches his neck to reach higher branches. The exercise of stretching up strengthens the muscles in the giraffe's neck and legs. This ability to stretch is also seen in the giraffe's offspring. b. A monkey accidentally drops her fruit in the salty water of a bay. She recovers the fruit and eats it. She discovers the fruit is cleaner and tastes better after it has been in the salty water. She continues to wash the fruit in the bay before eating it. Her offspring see what she has done and also wash their fruit in the salty water. Soon, the whole population of monkeys is washing their fruit. c. Several turtles hatch from a clutch of eggs buried in the sand on a beach. One of the turtles is the color of the sand; the others are darker in color. The turtles scurry toward the water, but one-by-one all of the dark turtles are eaten by birds until only the sand-colored turtle remains. The sand-colored turtle makes it into the water and immediately turns dark brown. The turtle grows, mates, and has offspring that are also sand-colored when they are born. d. A female alligator gives birth to a male alligator that has the ability to change color to bright white when it's in cold water. The baby alligator is quickly spotted by a large bird of prey and eaten. e. None of the above
