What are some examples of adaptation in species?

Adaptation in species refers to the changes that occur over time to help organisms survive in their environments. For example, the long neck of a giraffe allows it to reach high leaves, while polar bears have thick fur and fat layers to insulate against cold.

Can you give me more examples?

Sure! The peppered moth is a classic example; it changed color during the Industrial Revolution to blend in with soot-covered trees. Another example is the cactus, which has adapted to store water in arid environments.

What about human adaptations?

Humans have adapted in various ways, such as developing lactose tolerance in some populations to digest milk, and having varying skin tones based on geographical UV exposure.

How do these adaptations occur?

Adaptations occur through the process of natural selection, where traits that enhance survival and reproduction become more common in a population over generations.
