Homo
Let an agent explain the genus Homo, relay species, chronology, evolution, interbreeding and classification debates from paleoanthropology sources with positions attributed, describe the named fossils and proposals, and distinguish Homo from Australopithecus, Paranthropus, hominins and hominids as broader groups and race as a social concept.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the genus Homo, relay species, chronology, evolution, interbreeding and classification debates from paleoanthropology sources with positions attributed, describe the named fossils and proposals, and distinguish Homo from Australopithecus, Paranthropus, hominins and hominids as broader groups and race as a social concept.
The genus of hominins that includes modern humans, Homo sapiens, and extinct relatives such as Homo habilis, Homo erectus, Homo heidelbergensis, Homo neanderthalensis, Homo floresiensis and Homo naledi, with the earliest fossils attributed to the genus dating to about 2.8 million years ago; archaic humans is an informal term for non-modern members, and recent proposals the registry aliases name include the Harbin cranium from China, described in 2021 as Homo longi and linked by later molecular studies to Denisovans, and Homo juluensis, proposed in 2024 for some Chinese fossils, whose status is debated. Classification of species and interbreeding evidence are active research areas, with positions attributed.
What it is for: Classifying human species.
It can be explain species and chronology; relay evolutionary evidence; describe named fossils and proposals; present classification debates with attribution.
Distinguishing features
Larger brains over time
Stone tool traditions
Global dispersal
Interbreeding among lineages
What it looks like
Known from fossils, stone tools and ancient DNA; living members are modern humans.
Physical character
earliest attributed fossil: about 2.8 million years ago note - Ledi-Geraru jaw, Ethiopia
Homo sapiens earliest fossils: about 300,000 years ago note - Jebel Irhoud, Morocco
Homo juluensis proposal: 2024 year - status debated
How it is recognised
Genus of humans
Archaic human, Harbin cranium, Homo juluensis, Homo longi, humans
Australopithecus and Paranthropus are other hominin genera; hominins include all human-lineage species; hominids include great apes; race is not a biological species category

What the second pass must settle
- How should Homo longi, Homo juluensis and Denisovan naming be reconciled as research develops?
- Should archaic humans be a separate entry?
- How should paleoanthropology sources be linked and kept current?
