We Classify organisms for many reasons, mostly to organize the wide diversity of life on our planet.

Scientific namesScientific names

Binomial Nomenclature: The process of assigning two names to every organism. These are the names of the Genus, followed by the Species.

These names are internationally recognized by all scientists. As to avoid confusion between organisms.

Evolutionary ClassificationEvolutionary Classification

For a long time, classification was done by comparing animals traits. This led to many species being grouped together with little evolutionary history. It is now done with cladograms by comparing evolutionary relationships.

Molecular ClocksMolecular Clocks

As organisms evolve, harmless mutations build up in the DNA, these can be compared to view evolutionary history.

Kingdoms and DomainsKingdoms and Domains

All life is classified into three domains and five kingdoms,

and then further broken down through the other levels of

classification.
