翻譯作業 4-3節第二段

A particular niche is the result of long-term evolutionary changes in a species. Scientists use the niches of species to classify them broadly as generalists or specialists. Generalist species have broad niches. They can live in many different places, eat a variety of foods, and often tolerate a wide range of environmental conditions. Flies, cockroaches (Science Focus, at right), mice, rats, white-tailed deer, raccoons, and humans are generalist species.
