There is still no consensus among scientists about who Homo habilis, also known as the skilled human, truly was. This species was first described in 1964 by paleoanthropologist Louis Leakey, who identified it as one of the earliest representatives of the genus Homo based on skull and bone finds in Tanzania. Leakey believed that Homo habilis deserved human status and placed it at the very beginning of the evolutionary tree of modern humans.

Critique of Previous Classifications
However, contemporary scientists are increasingly questioning this assertion. Ian Tattersall from the American Museum of Natural History is convinced that Homo habilis cannot be classified within the genus Homo. According to him, the typical species of this genus is Homo sapiens, and other species are expected to share common traits with modern humans. However, in Tattersall’s view, there are no shared characteristics between Homo habilis and Homo sapiens.
“The discussion about who Homo habilis is has recently been revived following the discovery of the most complete skeleton of this enigmatic species ever found. The fossil remains discovered in Kenya provide the first insight into the limbs and body of this ancient hominid, showing that it resembles a monkey much more than any member of the genus Homo.”
The finding of a complete skeleton in Kenya has sparked a new discussion among anthropologists. The discovered remains allowed for a more detailed analysis of the morphology of Homo habilis, and the results indicate a much greater similarity to monkeys than to modern humans. This supports the idea that this species may have been separate from the evolutionary line leading to Homo sapiens.
Tools and Criteria for Classification
In the 1960s, scientists primarily determined membership in the genus Homo based on the ability to make tools rather than morphological traits. Louis Leakey believed that the findings of Oldowan tools over 2.5 million years old in Tanzania were associated specifically with Homo habilis. However, Tattersall emphasizes that this is not sufficient grounds for classifying the species as Homo, as morphology plays an equally important role.
Despite these doubts, many anthropologists hesitate to change the species name, as it does not fit into any other category. Homo habilis has noticeable differences from australopithecines, but it also lacks significant common traits with Homo sapiens. Experts emphasize that the traits that define the genus Homo only appear with Homo ergaster, which many scientists now consider the first true representative of the human lineage.
Thus, the question of the true nature of Homo habilis remains open. Aside from the ability to create tools, this species has almost no common traits with modern humans, and its place on the evolutionary tree still sparks numerous debates.
