Humans have ways to change how they act. They can adapt to different circumstances like rainy days, hot, dry days, and snowy days. We call this type of change an adaptation.
Animals can adapt to different circumstances, also.
They also adapt to different weather, but they cannot adapt as well as humans. For example, humans can adapt to living in space by building spaceships like the shuttle. Animals could not adapt to space without human help. A climate change might take thousands of years, but the animals would still have to adapt. We know that certain animals live in certain climates.
