The Classification of Organisms: Traditional and Modern Approaches

The video tutorial discusses the classification of organisms, starting with the traditional Linnaean system developed by Carl Linnaeus, which categorized organisms based on external structures into two kingdoms: animals and plants. With technological advancements, scientists discovered microorganisms and biochemical processes, leading to the expansion of kingdoms to include prokaryotes, fungi, and protists. The binomial system assigns organisms a genus and species name, facilitating global scientific communication. Recent discoveries have introduced a three-domain system, adding a layer above kingdoms, resulting in six kingdoms overall, including Archaea, Eubacteria, and Eukaryota.

What are the three domains in the new system of classification?

Explain the characteristics of the domain Archaea.
