Human Lineage: Hominins, Not a Line
Captions available
The idea
The hominin fossil record, per Bio 1787, shows a branching pattern of coexisting species over time, not one straight line leading to modern humans.
In practice
Several hominin species, including different Homo species, coexisted at points, later going extinct rather than transforming into the next.
Where people slip
A textbook diagram showing species one after another misrepresents this branching pattern as a single ladder-like progression.
