What classification of life includes humans, scientifically known as Homo sapiens?

The classification that includes humans, scientifically known as Homo sapiens, is Eukarya. This domain encompasses all organisms that have complex cells with membrane-bound organelles and a defined nucleus. Eukarya includes not only humans but also animals, plants, fungi, and various protists.

Humans belong to the kingdom Animalia within the Eukarya domain, which is characterized by multicellular organisms that are heterotrophic, meaning they obtain their food by consuming other organisms. The defining trait of Eukarya is the presence of eukaryotic cells, which distinguish them from organisms such as bacteria and archaea, both of which are prokaryotic and do not possess a nucleus or membrane-bound organelles.

The other classifications listed—Bacteria, Protista, and Archaea—represent different groups of organisms that do not include humans. Bacteria and Archaea comprise single-celled organisms that lack defined nuclei, while Protista includes a diverse range of mostly unicellular organisms, many of which are not closely related to humans. Therefore, Eukarya is the correct classification for Homo sapiens.
