"Although it will require much more complete evidence for the evolution of the skeleton of early humans below the neck to test their ideas properly."

There's the rub.

Just how many bones are there from our so called ancestors below the neck?
How many complete skeletons are there for examination to fully understand the dynamics of evolutionary progression for this theory?

Evidence is scant or no existent!

Good point.

Exactly, most of the fanciful trees the draw of human development are derived from a couple of skulls that have been found. Most or all which can be explained by individual mutations of a single human or sub group of humans. I was under the impression that scientists were suppose to seek the simplest solution that fits the evidence instead of the most fanciful based on eons of luck and some shared features. The human body does a LOT of things well running is just one of them. 26 traits they studied? The human body could be broken down in to thousands, even millions, of traits.
