Relationship of evolutionary development and foot pathology:

Many of the changes that the foot is assumed to have gone through during phylogenetic development can be seen in the developing ontogenetic development.

Recapitulation
'During embryological development, an organism passes through stages which resemble the structural form of several ancestral types of the species as it evolved' (Haekel's Law)
evident in the early stages of development of the human embryo and foetus

possible explanation for the existence of structural anomalies in the lower limb

Tax (1982) suggests that our technological environment has evolved more rapidly that the structure and function of the foot. The hard unyielding surfaces that we walk on put the contoured foot at a functional disadvantage as it is not designed for use on a hard flat surface  the foot has to pronate excessively to reach the ground.
