Chapter 18, Problem 6RQ

Outline the major adaptations that emerged during the evolution of vertebrates from fish to amphibians to reptiles to birds and mammals. Explain how these adaptations increased the fitness of the various groups for life on land.

Students have asked these similar questions
List three groups of adaptations that guided vertebrate evolution, and explain how each has contributed to the success of vertebrates.
Use the vertebrate lineage to explain how the cutaneous system (the skin) changed and evolved to life on land. Include which classes contributed key features and advancements. Your focus is on terrestrial vertebrates, but explain the basics of aquatic skin to show where the story started. Include how each change benefited that lineage in terms of their evolution to land (what niches did each new feature allow). HINT: Sometimes it's helpful to think in terms of Pros and Cons of the evolution of a feature. If you know I am looking for a word - bold or underline it. If there is the material you need to draw to support your answer upload that in the second question.
Adaptive radiation is when populations diverge from a common ancestor into new species,  each of which is adapted to its own unique niche. Provide evidence to highlight an example as to how this may have occurred in some of the species of penguins.
