Taxonomy naming and classifying of species, or a category in a formal system of classification. Systematics modern scientific study of the evolutionary relationships among organisms. Cladistics method of classifying organisms according to the order in time when homologies were inherited. Plants and animals share a common unicellular ancestor, aprox. 400-500 millino years ago, green algae began making the transition from water to land and eventually gave rise to plants. Animals, fungi, and plants evolved from ancient protists (eukaryotes with a nucleus: kingdom protista (membrane-bound dna, as opposed to bacteria, domain eukaryote (nucleus) both animals and plants. Large cells, nucleus, linear dna (chromosomes), have organelles. Prokaryotes have small cells, absence of nucleus, circular dna, no organelles.
