Who were our prehistoric human ancestors? This is a question that man has been asking for a long, long time. Could it be that learning about the embryology (the science that deals with development of embryos) of our foot will provide us with that knowledge?
In trying to find out who we’ve evolved from; anthropologists have zeroed in on morphological (structural) changes in fossils of upright walking creatures. They’ve studied the cranium, the capacity of the cranial vault, differences in the structure of the pelvis, length of the arm and leg bones, the structure of the wrists, and the opposability of the halux (big toe) in the foot.
But after examining many fossils of upright walkers, the anthropologists still couldn’t tell which of them were of human lineage and which were not. Their findings were inconclusive and at times contradictory, and as a result, their investigations have led to a dead end. They still don’t unanimously agree on who our direct human ancestors were.
Why? The reason is because they compared all the wrong parts of the upright walking individuals.
The one part the anthropologists didn’t consider is a specific part of the foot – the back part of the heel bone – which mirrors the evolution of the species and holds the answer to how humans evolved.
The Embryological Development Of The Foot May Hold The Answer To Who Were Our Direct Ancestors
In the womb of a present day human mother, when the fetus’ heel bone first emerges from the developing limb bud, it is structurally twisted inward. This same inward twist in the heel bone is seen in our direct ancestors nearly three million years ago.
And so it holds to reason that if the primate fossils uncovered by the anthropologists don’t have this twist, they are not a direct human ancestor.
One must look at the oldest foot fossils which came from upright walkers and determine if they had the inward twist of their heel bone. If they had the inward twist, they’re part of the human lineage. If not, they’re from a non-human lineage.
An example of this is the A.sebida, who lived some two million years ago. The heel bone in this individual had an inward structural twist and he evolved into the present day human. Whereas the A.aferensis, who walked the earth at the same time as the A.sebida. did not have the inward structural twist in his heel bone and became extinct.
Studying the embryological development of the human foot suggests that the PreClinical Clubfoot Deformity – a foot structure that has an inward twist in the heel bone and is present in millions of people today – was also present in our early ancestors.
