20. Evolutionary Origins: From Fish to Amphibian
The journey from aquatic fish to terrestrial amphibians marked a revolutionary shift in vertebrate evolution. Early transitional species like Tiktaalik developed primitive lungs and supportive limbs, enabling them to explore life beyond water. These adaptations laid the groundwork for the complex, versatile respiratory systems seen in modern amphibians. This evolutionary milestone not only shaped amphibian diversity but also set the stage for further vertebrate innovations on land. Learn more
