how were the classification systems of aristotle and linnaeus similar?
Both systems divided living things into 2 main groups, animal and plants, but aristotses system had 3 sublevels and Linnaeus's had 6. Aristotle divided by habitat and stems and Linnaeus divided by morphology.
With the advent of such fields of study as phylogenetics, cladistics, and systematics, the Linnaean system has progressed to a system of modern biological classification based on the evolutionary relationships between organisms, both living and extinct.ristotle used a very simple system of classification. He divided all living thing into two groups: plant and animals. Some of the terms he gave to animals, such as  invertebrates  and  vertebrates  are still commonly used today.
