I love the smell of b-s in a headline.
"Our study confirms that as early as six million years ago, basal hominins in Africa were already similar to later australopithecines in their anatomy and inferred locomotor biomechanics," adds Dr. Jungers. "At the same time, by way of the analysis, we see no special phylogenetic connection between Orrorin and our own genus, Homo." ...the authors articulate that the analysis and morphological comparisons among femora from the fossils showed that O. tugenensis is distinct from those of modern humans and the great apes in having a long, anteroposteriorly narrow neck and wide proximal shaft. Early Homo femora have larger heads and broader necks compared to early hominins. In addition to these features, modern human femora have short necks and mediolaterally narrow shafts. The challenge ahead, explains Dr. Jungers, is "to identify what precipitated the change from this ancient and successful adaptation of upright walking, and climbing, to our own obligate form of bipedalism."
...IOW, to identify how a parallel ancient and successful adaptation of upright walking led to a dead end.

My intent was to encourage people to check things out that are presented as fact. Is that ok with you?

Walking uprightly is not as easy as it sounds.

Upright Walking Began 6 Million Years Ago That's right, exactly 599,993,453 years before the Good Lord created the Earth and all the planets that revolve around it!

Seems the facts were presented as evidence that support the hypothesis.

just because it was in church doesnt make it true..
True. I also encourage people to read those Bibles they carry around and make sure that what they hear is grounded in scripture.

Well, we did things right, in those days. My sister was walking at nine months, so when I came along, I guess my folks were not really surprised.

Before transforming to full upright walking, I would expect in order to face off predators, these hominids would have developed some level of language to coordinate group defense and attacks and would have routinely carried weapons such as clubs and rocks. I don't know what language has to do with it.
Walking upright does give you the advantage of free use of your arms for something other than travel, including the use of tools or weapons.
But self-defense is pretty instinctive, regardless of how you move.

This is crap! Just another way to sow seeds of doubt. The bone was probably only several hundred years old.

Both of my kids were early walkers, but 6 million years? Gimme a break!
