Detailed explanation-1: -The correct answer is D. (Taste aversion is a universal survival mechanism.). By avoiding toxic food and possible poisoning, it is more likely that one will survive and have offspring.
Detailed explanation-2: -In the 1950s, John Garcia demonstrated conditioned taste aversion under quite different laboratory conditions and came to realize that the phenomenon represented much more than a potential means of improving pest control.
Detailed explanation-3: -Conditioned taste aversions are a great example of some of the fundamental mechanics of classical conditioning. The previously neutral stimulus (the food) is paired with an unconditioned stimulus (an illness), which leads to an unconditioned response (feeling sick).
Detailed explanation-4: -Taste aversion, Garcia demonstrated, can occur after only one exposure to a food that is combined with a stimulus that induces nausea or vomiting. He discovered that food aversions can occur even when the food is consumed as much as 75 minutes before the injection of radiation that causes vomiting.
Detailed explanation-5: -This is considered an adaptive trait or survival mechanism that enables the organism to avoid poisonous substances (e.g., poisonous berries) before they cause harm. The aversion reduces consuming the same substance (or something that tastes similar) in the future, thus avoiding poisoning.
