Evolution Connection Lizards and snakes cannotbreathe while chewing food because the connection betweentheir external nostrils and their esophagus is in the mouth.In contrast, mammals can continue breathing throughthe nostrils while chewing food in the mouth. However,choking sometimes occurs when the paths of air and foodcross each other. Thinking about the high oxygen demandof active endotherms, explain how the concept of descentwith modification explains this “imperfect” anatomy of someamniotes (see Figure 34.2 to review vertebrate phylogeny).

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
