Increasing specialization of structure and function among animals of the same class and order for survival in new and different environments is called

The process of animals within the same class and order becoming more specialized in their structure and function to survive in new and different environments is known as adaptive radiation. This means that over time, the animals develop specific adaptations to fit the unique conditions of their environment, such as changes in their diet or physical characteristics. For example, a group of finches on the Galapagos Islands developed different beak shapes to suit their specific diets. This process is important for the survival and success of species in changing environments.
