The study of life and the processes thereof. Some general principles as to how living things work are studied in [[Biochemistry]] and [[Genetics]]. To find out more about specific organisms we investigate their [[Anatomy]], [[Physiology]], and [[Ontogeny]]. To find out about how organisms relate we investigate their [[Ecology]]. One of the central concepts in biology is the principle of [[Theory of Evolution|Evolution]]. The descent of an organism is called its [[Phylogeny]]; these are studied using all sorts of evidence, including of course the study of ancient life, [[Palaeontology]]. The classification of living things is called [[Taxonomy]], and ideally should reflect the evolutionary trees of the different creatures. Linnaean Taxonomy divides living things into five top-level groups, called ''kingdoms'': * Kingdom [[Prokaryotae]] - bacteria, etc. Formerly called [[Monera]] * Kingdom [[Protista]] - basal protozoa, algae, etc. * Kingdom [[Plantae]] - green algae & plants * Kingdom [[Fungi]] - chytrids & fungi * Kingdom [[Animalia]] - animals and then further into phylum, class, order, family, genus and species. One way to remember the ordering is "King Phillip Cam Over For Great Spaghetti". Linnaean Taxonomy does not follow evolution too well, but does pretty well for something devloped a hundred (?) years before evolution.
