Global climate is warming, and extreme weather is increasing. Which animals are more resistant to the effects of climate change?

Global warming has been happening, extreme weather has also increased, and the lives of small animals will also be affected. Scientists have studied some mammals living on land, and found that alpacas and African elephants have strong cold resistance, and they are not vulnerable to extreme weather. These two animals have a long life span, few offspring and strong individual viability. And like some small mammals with many offspring, such as mice, they are vulnerable to the weather. As the weather changes, small animals may also have some different changes because of the regional climate. For example, the life span of individuals has become longer, but the offspring have decreased.

People can take off their clothes when it is hot, but when it is cold, they can hide in their close-fitting clothes in the house and keep warm in front of the brazier or stove. Therefore, people are more resistant to extreme weather than animals. Adults must rely on tools. Without tools, people can't live. Under the same conditions, animals are certainly more likely to survive in this weather, because they will rely on their bodies to resist various weather influences.

From the above research, we can see that the survival ability of large animals is slightly stronger than that of small animals, and their life span is longer. For example, elephants can live for a long time, but mice can't. However, there are fewer offspring of elephants, so it takes a lot of effort to give birth to a baby elephant. Therefore, different animals will have different changes when dealing with extreme weather, which is also a result of natural selection. For example, in order to cope with natural conditions such as drought, large animals will pay more attention to their offspring, hoping that they can live longer. In this way, each generation will be better than the previous generation, and the genes of large animals will be preserved.

The earth is constantly changing, and human research has not stopped.
