| 1 |
Domain |
The broadest level of classification. Organisms are classified by basic cell type and genetic difference. There are three domains: Bacteria, Archaea and Eukarya. |
Eukarya - organisms with complex, membrane-bounded cells(like 🐕animals, 🍀plants, 🍄fungi and protists). |
| 2 |
Kingdom |
A major category under domain. Organisms are grouped by general characteristics such as how they get energy, cell structure, and reproduction. |
Animalia - multicellular organisms that consume organic material, and can usually move. |
| 3 |
Phylum |
Groups organisms with the same basic body structure or body plans, such as symmetry, presence of backbone, or segmented bodies. |
Chordata - animals that have, at some stage, a notochord(like a backbone). |
| 4 |
Class |
It classify organisms based on more specific traits like reproduction way, internal anatomy and development. |
Mammalia - animals that have hair/fur and produce 🍼milk to feed their young. |
| 5 |
Order |
Group together families with similar characteristics or evolutionary traits. Often based on limb structures, diet, and behavior. |
Primates - animals with grasping hands, forward-facing eyes, and large brains(monkeys, apes, humans). |
| 6 |
Family |
Group related with genera (plural of genus) together. Members share more recent common ancestors and often resemble each other closely. |
Hominidae - great apes, including humans, chimpanzees, gorillas, and orangutans. |
| 7 |
Genus |
A group of species that are very similar and closely related. The genus is the first part of a scientific name. |
Homo - includes modern humans and closely related extinct species. |
| 8 |
Species |
The most specific level. A species is a group of organisms that can interbreed and produce fertile offspring. This is second part of a scientific name. |
Homo sapiens - modern humans. |
