What conclusions can be made regarding the ultimate causes of intelligence?

Question

Quizplus · Accepted Answer

The idea that intelligence evolved to allow humans a high degree of flexible behavior is supported by research in both evolutionary biology and cognitive psychology. It is believed that intelligence provides humans with the ability to adapt to different environmental challenges and to solve complex problems, ultimately increasing their chances of survival and reproduction.

Answer: C
 There is evidence to suggest that animals with higher intelligence tend to have better genes for survival, as these genes may be directly or indirectly linked to cognitive abilities. This is known as the "intelligence-fitness" hypothesis, which proposes that intelligence and fitness (i.e. reproductive success) are correlated. Therefore, animals that are smarter may be more likely to survive and pass on their genes to future generations.

Answers B and D are incorrect because there is no evidence to support the idea that intelligence evolved to help humans have a high degree of consistency in their behavior, and there is overwhelming evidence that intelligence is an evolved behavior in humans and other animals.
