The significance of adaptation in species survival lies in its role in enhancing a species’ ability to thrive in changing environments. Adaptation allows organisms to develop traits that improve their chances of survival and reproduction under specific environmental conditions. This can include physiological changes, behavioral modifications, or structural alterations. Without adaptation, species may struggle to cope with factors like climate change, habitat loss, or new predators, possibly leading to extinction. Ultimately, adaptation is a key mechanism through which species maintain their presence and stability within ecosystems.
