Final answer:

In vertebrate evolution, the endoskeleton, amniotic egg, and reptilian scales played crucial roles in adaptation and survival.


Explanation:

Features of Vertebrate Evolution

In vertebrate evolution, the endoskeleton is an internal support system that allowed for large, heavy bodies. The amniotic egg is a structure that developed within the mesoderm and allowed for more complex internal organ formation. The scales of reptiles, which are a flexible structure that supports the nerve cord, helped in preventing water loss from skin.
