What is the relationship between adaptations and extinctions?

Sample Response: Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur

Because extinction is often caused by change in environment and if a species can't adapt to an environment it often leads to extinction
