I had the good fortune of talking with two anthropologists, Jeremy De Silva at Boston University and Bernard Zipfel at the University of Witwatersrand, Johannesburg, South Africa; who excitedly recounted their recent discoveries of fossilized bones of A.sebida, the ancestor of homo sapiens– that dated back at two million years ago.

While investigating the foot fossils of the A.sebida’s feet, they found a torsion (twist) in both the heel bone and talus (the bone on top of the heel 

Why is this information significant?

Though the anthropologists made no connection between the torsion in the heel and talus bones of our ancestors and the way that they walked, their discoveries confirmed and crystallized what I had already discovered many years ago – the foot structure I named ‘PreClinical Clubfoot Deformity’.

The PreClinical Clubfoot Deformity is defined as a foot structure that has a torsion in the heel bone and talus – the same torsion as found in the fossilized foot bones.

The fossilized footprints appeared to be exactly the same footprints that you can see today – about three million years later – in a person who has a PreClinical Clubfoot Deformity.

Why Is The PreClinical Clubfoot Deformity – A Several Million Year Old Foot Structure – Still Around Today?

Our ancestors evolved from being tree dwellers that occasionally walked on the ground on all four legs, to two-legged walkers living predominately on the ground. The PreClinical Clubfoot Deformity represented the change in the foot structure that allowed them to walk on two feet. All our ancestors had a PreClinical Clubfoot Deformity – then it was a normal foot structure. And at that time it served their purposes as it made them more efficient hunters.

Over the next few million years, as our ancestors became more and more solely two-legged walkers (living more on the savanna and less in the trees) the foot continued its’ evolution making it easier and easier to walk on two feet. Hence, over time, the PreClinical Clubfoot Deformity started evolving into the Primus Metatarsus Supinatus (Rothbarts Foot) and then the plantargrade foot.

More specifically, the human foot is in the process of evolving from what was predominantly a PreClinical Clubfoot structure (in which the talus and calcaneous have a structural inward twist) towards a plantargrade foot (in which there is no longer an abnormal structural twist). The Rothbarts Foot (in which just the talus has a structural inward twist) represents an intermediate stage in this evolutionary process.

This has been a slow evolutionary process over millions of years and will probably take another several million years for everyone’s foot structure to become a plantargrade foot.

Currently, the Rothbarts Foot and PreClinical Clubfoot Deformity are present in about 80% of the world population. Several million years from now, it will be difficult to find an individual with one of these two-foot structures.

My hypothesis to explain this: The PreClinical Clubfoot Deformity – which may have served us well millions of years ago – is no longer useful or helpful, as evidenced by the pandemic of chronic muscle and joint pain that we see in people who have this foot structure today.

bone). From these feet and previously found fossilized foot prints, they deducted that these early human prototypes walked predominantly upright on their feet. And as they walked, they first placed their weight on the outside of their heel bone and then their midfoot collapsed before rolling off their big toe.
