Tetrapod evolution refers to the process through which vertebrates transitioned from aquatic to terrestrial environments, leading to the development of the four-limbed animals we recognize today, including amphibians, reptiles, birds, and mammals. This evolutionary milestone was marked by significant anatomical and physiological changes that allowed these creatures to adapt to life on land, such as modifications in limb structure and respiratory systems. Understanding tetrapod evolution sheds light on how various lineages diverged and adapted to different ecological niches over millions of years.
