What are some examples of adaptation and modification?

Adaptation refers to the process by which organisms develop traits that enhance their survival in specific environments. For example, polar bears have thick fur and a layer of fat to insulate against cold temperatures. Modification, on the other hand, often involves human-driven changes to species or environments, such as selective breeding in agriculture to create crops that are more resistant to pests. An example of this is the development of disease-resistant rice varieties through genetic modification.
