How do environments change over time?

What causes species adaptation over time?

Adaptations are the result of evolution. Evolution is a change in a species over long periods of time. Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.

Are pandas specialist or generalist?

Pandas are an excellent example of a herbivore specialist, because they have a specific niche that they live in and their diet consists only of bamboo. Generalists usually aren’t picky eaters, and can eat a wide variety of things, as well as having a large area in which they inhabit.
