Abstract:
Developmental observations in foot laterality suggest increasing right-footedness from early childhood to young adult years, with few reports on behaviour beyond this time frame. This investigation confirmed recent suggestions by Porac (1996) of a continuation of this trend into middle and older adulthood, along with significant decreases in mixed-and left-foot preferences. Trends towards increasing right-footedness are linked to hemispheric heterochrony (right hemisphere ageing) and the right-sided world phenomenon.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
