With the upright gait, *everything* began...

The emerging of the upright, permanently bipedal gait and the associated anatomical changes are, without a doubt, the most striking and probably the most decisive evolutionary steps our ancestors have made on their way to modern man. As we know today, they have clearly preceded most other physical, social, and cultural developments in the process of hominization.

 

For example, fossil finds of Australopithecus afarensis (the last direct ancestors of Homo) still show clearly primitive, ape-like traits in terms of brain size, head, breast and upper limb. At the same time, spine, pelvis, leg, knee and foot are already clearly human-like, and clear indications of a locomotional pattern already very similar to our own - more than three million years ago.

 

"The structure of the human musculoskeletal system is the result of a billionfold adaptation to its surroundings. The development of the walking-foot was the central part of leaving the arboreal habitat and developing the upright gait.

An efficient cross-bracing of the foot was indispensable for the stabilization of the erected bipedal body. Thus, the arch of foot, the plantar aponeurosis, the Mm. peronei and the M. vastus medialis (of M. quadriceps femoris), were developed.

It is precisely these structures that are positively influenced by MT III technology, which in turn – via the functional chain – have an effect on the whole body, up to neck and head.

By helping the body to regain its original evolutionary determined upright posture, it can counteract numerous medical conditions resulting from a disorder of the human body's erection."

3.6 million year old footprints of A. afarensis in petrified volcanic ash, that have been found in Laetoli (Tanzania) in 1976, testify in astonishing immediacy, how the gait of A. afarensis was already very similar to that of modern man - a million years before the first stone tools emerged.
