問題詳情

III. Reading Comprehension (24%) (1) Intelligence has given humankind a distinct advantage over other creatures. However, the evolution of ourintelligence has left biologist Dr. Tadeusz Kawecki asking the question, “If it is so great to be smart, why have mostanimals remained dumb?”      In fact, learning can sometimes be a dangerous thing because it takes time and energy. For example, birds are notborn knowing how to make use of their main evolutionary advantage: the ability to fly. And the longer it takes to learn,the more likely a baby bird is to be an easy target for predators. According to Dr. Kawecki, each species evolves to apoint where the costs and benefits of learning are equal. Thus, an animal only learns what its environment requires it to.      Now we have an idea of why animals don’t continue to learn, but if our roles were reversed, what would animals testus on? Dogs may test our sense of smell and ability to remember terrain. In those sorts of tests, we would surely fail whencompared to our canine counterparts. Then, they might look at us and ask, “What is the point of human intelligence?”
