Therefore, the need to group organisms and then order them arises. - Taxonomy – Theory and practice of classifying organisms. - Taxon (pl. taxa) – Any group in which we formerly place organisms. Ex: kingdom, phylum, species, etc, informal groupings are those such as algae. - Systematics – To understand the diversity of organisms given their evolutionary relationships. - If we use a classification system that uses evolution and is based on it, it is a natural - classification system. - The system we use today did not originate in natural classification, it originated with artificial classification, it tried to put everything into categories to keep everything in order - Developed by Carl von Linne, Caralus Linnaeus, he gave latin names to all the organisms, founder of modern classification, worked in 1700’s.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
