Species of the homo genus

Nomenclature have been given to living species according to established rules from biological definition of species to the present day, Changing these names and the emergence of synonyms is a common phenomenon in the history of taxonomy. However, even if these names change, the organism in question remains the same as it was in the initial nomenclature. This is because the organism exists concretely, and it is not possible for this organism to have existed in isolation. The organism in question stands as a biological reality, existing and living within a population. This applies to humans as well, as in 1758, Linnaeus named humans according to established rules as Homo sapiens. At that time, there was only one species defined in the Homo genus, which was Homo sapiens. In current catalogs, the Homo genus, along with the Pan, Pongo, and Gorilla genera, forms the Hominidae family. In these catalogs, besides the Homo genus, most other genera have at least two species, and many also have subspecies. The idea of evolution, which suggests that humans, like other organisms, have descended from common ancestors, was proposed by Darwin in his book "On the Origin of Species" in 1859, exactly 101 years after Linnaeus's nomenclature. As support for this idea grew over time, the notion that there could be different species within the Homo genus alongside human evolution was embraced by some biologists, paleontologists, and paleoanthropologists. This has resulted in reaching 20 recognized species within the Homo genus. In this study, the scientific status of these proposed species will be examined. The aim is to elucidate the nature of these "species" through scientific and philosophical approaches.
