Final answer:
Sexual reproduction is not necessary for all species to avoid extinction, but it is important for the long-term survival and adaptation of a species.
Step-by-step explanation:
Sexual reproduction is not necessary for all species to avoid extinction, but it is important for the long-term survival and adaptation of a species. The genetic diversity introduced through sexual reproduction helps species to cope with changing and unpredictable environments. By combining genetic material from two individuals, sexual reproduction creates offspring that are genetically different from their parents, allowing for new combinations of traits and potentially increasing the chances of survival in a changing environment.
