Revised Answer (140 words):

In the lecture, the professor provides an example illustrating the concept of generalization for avoiding predators, meaning that animals can sometimes recognize new predators based on their similarity to known predators. The example involves a type of small fish called minnows, which are hunted by lake trout. When minnows detect the scent of lake trout, they gather together and cease movement. As a result, it becomes difficult for trout to locate and consume them. In an experiment, minnows were exposed to the scents of two unfamiliar types of fish. The first type is brook trout, which is similar to their predator, lake trout. The second type is a completely different species of fish. As a result, minnows exhibit the same behavior as they do with lake trout. They gather together and cease movement. However, when encountering the second type of fish, they exhibit normal behavior.
