Natural Selection

A large herd of goats lives in a field full of poison ivy.  Some goats are able to eat the poison ivy while others have become sick when they eat it. Over time the herd as a whole will tend to

• Become more likely to eat poison ivy.

• Become less likely to eat poison ivy.

• Not change in the proportion of goats that can and can not eat poison ivy.

• Eat all the poison ivy and leave only plants all the goats can eat.
