Why are reptiles the first true land vertabrates?
Reptiles were the first true land vertebrates because they were able to successfully adapt to terrestrial environments with features such as scales to prevent water loss, amniotic eggs for reproduction on land, and efficient respiratory systems for breathing air. These adaptations allowed reptiles to thrive on land, marking a significant evolutionary shift from their amphibian ancestors.
The first animals to live successfully on land were?
The first vertebrates to live on land did not come out of the sea until 370 billion years ago. Those first land vertebrates were amphibians. Several structural changes in the bodies of amphibians occurred as they adapted to life on land. Amphibians had moist breathing sacs -lungs- which allowed the animals to absorb oxygen from air. The limbs of amphibians are thought to have derived from the bones of fish fins. Because of there strong flexible internal skeletons the bodies of vertebrates can be much larger than those of insects. While amphibians were well adapted tp their environment, a new group had evolved from them. They evolved to reptiles but we are on the subject of the first land animal so that's that.
