Scientific understanding of relationships between living things has changed dramatically Since the Linnaean era and classical taxonomy. . . Modern taxonomy attempts to represent groups of animals in a system that reflects an understanding of their evolutionary relationships—hence the « class » of birds into the « class » of reptiles.

How did taxonomy develop?

Modern taxonomy officially began in Systema Naturae in 1758, Classics by Carolus Linnaeus. This module is the first of a two-part series on taxonomy of species, focusing on Linnaeus’s system of plant and animal classification and nomenclature.

Which level of classification was new and added to the system in the 1990s?

In the mid-1990s, a whole new level was added to top-level hierarchy. This happened because scientists learned that the prokaryotic kingdom contained two very different organisms.

What is a modern taxonomy?

Why create a three-domain system?

Woese argues that in Basis of 16S rRNA genetic differences, bacteria, archaea, and eukaryotes each arose from ancestors with poor genetic mechanisms, often referred to as ancestors. To reflect these major bloodlines, he treats each bloodline as a realm, divided into several distinct kingdoms.
