Yet, because of the paucity of the fossil record, the fragmentary nature of fossil remains, and the difficulty of inferring behavior from fossils, significant questions remain unanswered concerning the evolution of human bipedalism. It is important to note here that while no values were reported as negative, unlike in our facial reconstruction of Lucy, we think the lack of lateral points on the skull offered by the equations resulted in too much intuition at these areas.
Today, methods detailing the reconstruction process of the face are ubiquitous in the facial approximation literature ,;; ; ; ;.
If intuited reconstructions that are produced by the same practitioner can vary, in particular with input from outside sources, then one can see clearly why reconstructions of the same individual produced by separate practitioners could vary wildly from museum to museum.

This once again highlights the difficulties and complexities of muscle reconstructions but also the enormous opportunities that we now have to make progress in the area of muscle, facial, and whole-body reconstructions. Based on the pernicious bias out of which this image was made, it is hardly appropriate to use it for disseminating scientific information about human evolution.
Surface EMGs were also secured to the skin at the approximate midpoints between origin and insertion of the biceps femoris hamstringsand the gluteus medius. There is currently no known method for deriving anthropometric measurements from genomes, highlighting a major problem with the proposed body plan.
The most substantial difference between humans and apes is that humans lack the GMIF and have only an enlarged GMP portion of the muscle hereafter referred to as the human GM. A final hypothesized functional explanation for enlargement of the human GM is running, which is biomechanically very different from walking, and appears to stimulate higher levels of EMG activity than walking as noted above. How did the australopithecines walk?
Conversely, the use of equations for predicting facial tissue thicknesses from craniometric measurements is gaining traction ; ; ;.

Flexion of the hips, knees and ankles between HS and MS during running functions to store up elastic energy in the tendons of the legs; this energy is then released as kinetic energy through recoil during the second half of stance, helping to propel the body back into the air.
The more proximal relationship of Neandertals to modern humans makes the use of the equations more viable.
