Document Summary
Systematics study of the diversity of organisms and their evolutionary relationship. (includes taxonomy) Taxonomy science of naming, describing, and classifying organisms. Taxon (pl. taxa) formal taxonomic level. Refers to any formal group an organism is placed in. A photosynthetic organism (algae) has no taxonomic significance just like non- photosynthetic organisms (protozoa) Helps us remember characteristics of organisms (ex: mammalian mammary glands, hair, warm blooded); but there are some things that we don"t know (ex: whether or not the organism can fly) Based on evolutionary relationships to the extent that we understand them. But the system that we actually use didn"t start out as a natural system , it started out as an. Carl von linne (1707 1778) aka linnaeus. Started classifying plants then moved to animals. Ex: grouped animals basing them on whether or not they had heads (starfish/jellyfish headless fish that"s not really a fish) Evolution began to be taken seriously scientisits decided that classification systems should reflect phylogency.
