3 Evidence indicates that animals evolved from choanoflagellates (protists) ~ 570 mya Single cells Often clonal Heterotroph No specialization or coodination between cells
4 Animal Classification 1. DNA sequencing 2. Body Symmetry 3. Presence or absence of body cavity 4. Embyonic Development
6 Body Cavity Most bilateral animals have body cavities Body cavities are fluid-filled cavities between the digestive tube and the outer body wall Functions: skeleton, providing support for the body and a framework against which muscles can act protective buffer between the internal organs and the outside world They can allow organs to move independently of the body wall
