Stimulating Brain Development: Evolution Of The Brain Spurred By Movement (a speculative hypothesis)

We previously mentioned the early hominid development of upright, obligatory, habitual bipedal posture mentioning the richer protein and calorie dense food which may have enabled better brain development. We’ll expand on that a bit with a “big think” and take it down a [...]

The great toe was in similar alignment to modern day humans. An arch was present. [...]
