3.4. CLASSIFICATION OF LIVING THINGS

The most important attemps of classifying living things are:

Eukaryotic cells

Prokaryotic cells

In your book, the five-kingdom system is used. We´ll use all of them, except that of Linnaeus, of course.


3.4. CLASSIFICATION OF LIVING THINGS

Carolus Linnaeus (1707-1778)

Systema naturae (1735)

The classification systems of both Aristotle and Linnaeus started with the same two groups: Plants and Animals. Linnaeus called these groups kingdoms. But, unlike Aristotle, Linnaeus divided kingdom into five levels: class, order, genus, species, and variety
