Document Summary
The study of biological classification is called taxanomy. Carolus linnaeus- the father of modern taxonomy. Linnaeus invented three supreme categories, or kingdoms: animal vegetable, and mineral. Today"s biologists leave the mineral kingdom to the geologists and have expanded linnaeus"s two living kingdoms to six. Linnaeus"s great contribution was a system of classification based on hierarchy, a grouping of objects by degrees of complexity, grade, or class. Systems of classification may be artificial or natural. A family tree showing the relationship of kingdoms presumably envolved from a distant common ancestor. The bacteria and archae contain single-celled organisms without nuclei or organells; collectively, they are called prokaryotes. The fungi, protists, animals, and plants contain organisms with cells having nulei and organelles; collectively, they are called eukaryotes. The marine environment is classified into distinct zones, areas with homogeneous physical features. They are classified by location and the behavior of the organisms found there.
