Document Summary
Chapter #5 macroevolution: processes of vertebrate and mammalian evolution. Discovering the human place in the organic world. In biology, the ordering of organisms into categories, such as orders, families, and genera, to show evolutionary relationships: multicellular organisms that move about and ingest food are called animals. Within the kingdom animalia, there are more than 20 major groups called phyla: chordata is one of the phyla. The phylum of the animal kingdom that includes vertebrates. All animals with a nerve cord, gill slits (at some stage in development) and a supporting cord along the back: vertebrates. Animal with segmented, bony spinal columns; includes fishes, amphibians, reptiles (including birds), and mammals. Organisms are classified first according to their physical similarities: devised by linnaeus. Like a musical score with a basic theme, small variations on the pattern can produce the different tunes that differentiate one organism from another.
