Did narwhals evolve

Answer 1

Yes, Narwhals evolved from a common ancestor shared with other cetaceans, adapting to their Arctic environment over millions of years. Their most distinctive feature, the long spiral tusk, is actually an elongated tooth and is thought to have evolved for mating displays and social interactions. Fossil evidence suggests that narwhals and their relatives have undergone significant changes to thrive in cold, deep-water habitats. This evolutionary process has allowed them to become specialized hunters of fish and squid in the Arctic waters.
