Taxonomy and systematics

The science of taxonomy and systematics involves classifying organisms according to natural and evolutionary relationships. The system in wide use dates back to the eighteenth century, when Swedish botanist Carl Linnaeus devised a way of naming, ranking, and classifying organisms. But with all our scientific progress, is this still relevant today? And what other ways are there of examining wildlife? Explore the Museum’s extensive resources to discover the answers.
