OUR PLACE IN NATURE Linnaeus (Carl Von Linne) Looked at the anatomy and the physiology of living things. Assigned them a position in a TAXONOMY (a system of biological classification in which organisms are arranged for the first time.) Organisms are arranged into larger groups then into increasingly smaller groups that are based on an analysis of similarities and differences in their biological traits. Published Systema Naturae (1735) Humans are placed in.... Kingdom Animalia which means that they are related to all organisms which possess a nervous system, whose nourishment is acquired by digesting food and whose anatomy allows for movement. Phylum Chordata which means that humans have a notochord (a flexible chord that runs the length of back and connects to the brain.) Sub-Phylum Vertebrata, which means that humans have a true backbone or spine. Class Mammalia means that humans have hair, are warm-blooded and suckle their young.
