Is Homo affinis erectus a direct human ancestor?

Maybe—but the evidence is still thin.

The recent discovery of Homo aff. erectus in Spain has sparked excitement. Unlike speculative claims about Anadoluvius turkae, this fossil is a hominin, meaning it belongs to the human evolutionary branch. However, whether it represents a direct ancestor of Homo sapiens or an extinct cousin remains uncertain.

So far, only part of a face—mainly cheekbone and upper jaw fragments—has been found, dating to between 1.1 and 1.4 million years ago. Researchers say it shows similarities to Homo erectus, but its exact place in the evolutionary tree is still up for debate.

Some have suggested this find could help clarify early human migration into Europe. But let’s not jump ahead—the evidence is far from conclusive. While this hominin may have played a role in the broader human story, whether it directly led to us remains to be seen.

The likelier scenario? It was one of several early human species or populations that coexisted in Eurasia, part of an evolutionary experiment with multiple offshoots. With only facial bones to go on, we have no limb fossils to tell us how it moved, its body proportions, or other key details about its way of life.

For now, H. aff. erectus is a fascinating addition to the human family tree—but we do not yet know whether it belongs on our direct branch.
