Perhaps the most challenging section for students is the evolution of body cavities. The 7th edition clarifies the distinction between acoelomates, pseudocoelomates, and coelomates. It explains the hydrostatic skeleton and how the development of a true coelom allowed for the independent movement of the gut and the body wall—a crucial step in the evolution of larger, more complex animals.
