Original Answer: Well, in the reading passage, Acceptation Exaptation(接受改为异化，因为这是原文中的正确词汇) is described as a feature on some animal species to meet the environment and increase the chance to survive. In the lecture, the professor gives an example of a kind of bird which lives by rivers and marshes and eats fish under the water. But it's pretty hard for them to see the fish under the water by the sunshine on the river because there is sun reflection and the glare stops them from seeing the fish. So they use their wings to block the sun. Just like the umbrella and eliminate the disturbance of glare and reflection. This movement well and nicely illustrates the expectation.

Corrected Answer: Well, in the reading passage, Acceptation Exaptation(接受改为异化，因为这是原文中的正确词汇) is described as a feature in some animal species that adapts to their environment and increases their chances of survival. In the lecture, the professor provides an example of a type of bird that inhabits rivers and marshes and feeds on fish beneath the water's surface. However, it is quite challenging for these birds to spot fish underwater due to sunlight reflecting off the water's surface, causing glare that obstructs their view. To overcome this issue, they utilize their wings to block out sunlight, similar to an umbrella, effectively eliminating glare and reflections. This adaptation aptly demonstrates exaptation.

Revised 140-word Answer: In the reading passage, Exaptation is described as a feature in some animal species that adapts to their environment and increases their chances of survival. The lecture provides an example of a type of bird that inhabits rivers and marshes, feeding on fish beneath the water's surface. However, spotting fish underwater is challenging for these birds due to sunlight reflecting off the water's surface, causing glare that obstructs their view. To overcome this issue, they utilize their wings to block out sunlight, similar to an umbrella, effectively eliminating glare and reflections. This adaptation aptly demonstrates exaptation, showcasing how animals can repurpose existing features to address new challenges in their environment. The heron's ability to use its wings for both flying and blocking sunlight highlights the concept of exaptation and its role in enhancing an animal's chances of survival.
