Ancient Foot Suggests How Man Gave Up Treehouses
LiveScience ^ | Wednesday, March 28, 2012 | Charles Choi

Ancient foot bones from a recently discovered pre-human species, which had opposable big toes like a gorilla's, could shed light on how the ancestors of humanity came to walk upright, researchers say.

Humans dominate the planet partly because walking upright frees their hands for tool use. Among the earliest known relatives of humanity to walk upright was Australopithecus afarensis, the species including the famed "Lucy." This hominin is a leading candidate for direct ancestor of the human lineage, living about 2.9 million to 3.8 million years ago in East Africa.

Although Lucy and her kin were bipedal, there is debate about how much they depended on life in trees. Now scientists also have fossils of a hitherto unknown species of hominin that lived about the same time and place as Australopithecus afarensis...

The 3.4-million-year-old fossils were discovered in 2009 in a part of Ethiopia known as Burtele. Nowadays this area is hot and dry, with temperatures skyrocketing up to 110 degrees Fahrenheit (43 degrees Celsius). But "nearby fossils of fish, crocodiles and turtles and physical and chemical characteristics of sediments show the environment was a mosaic of river and delta channels adjacent to an open woodland of trees and bushes," said fellow Case Western researcher Beverly Saylor.

Scientists have long argued that Australopithecus afarensis was the only pre-human species between 3 million and 4 million years ago. These new fossils of an unknown hominin species are the first incontrovertible evidence that at least two pre-human species lived at the same time and place around 3.4 million years ago.

The fossils include eight bones from the front half of a right foot. Such hominin fossils are rare, since they are fragile and subject to decay or carnivores.

No, that’s pretty obviously *not* an ape footprint. Apes are generally arborial, having longer toes for gripping, and a thumblike opposable big toe, leaving a footprint more like a handprint. That isn’t the case with humans like the Neanderthals.

You have it wrong now, why would anything have changed?

The Neanderthal footprint is more like the orang’s than that of a chimpanzee. It sure as hell is not similar to one of ours.

No, as a matter of fact, it isn't. You make yourself look more foolish each time you post.

I was seeing images of some other variety of orang last night but, for that matter, a gorilla's footprints are certainly closer to the Neanderthals than ours are:

Here's the problem:

You can't have it both ways. It appears that some of these clowns at least comprehend that if they were to show a Neanderthal skeleton with feet which correspond to actual footprints, the whole world would immediate grasp the fact that the Neanderthal was an ape, that ALL hominids were (bipedal) apes, and that we are not descended from or in any way related to any of them. I.e. it would blow their stupid little kum-bay-ah/evolutionist religion apart.

The only other alleged variety is the Orang-Pendek, a crypto-animal, and those attributed to it look like a gorilla’s. Neither one looks like Neandertal.

Still looks more like the Neanderthal footprint than ours do.

Scholars who studied Neanderthals early on claimed they had prehensile feet:

Our image of Neanderthals as "dim-witted brutes" originally came from Marcellin Boule, a French authority on fossils who reconstructed a near complete skeleton found in southwestern France, and claimed it had "prehensile feet, could not fully extend his legs, and thrust his head awkwardly forward because his spine prevented him from standing upright." In his scientific paper he described the "brutish appearance of this muscular and clumsy body."

That accords quite well with the real footprints but not, as I note, with reconstructions meant for idiot yuppies such as you see in the Natural History Museum, which as the image clearly shows, have human-like feet and, again, the problem appears to involve the pseudo-religion of Evolutionism.

Boule's claim of them not being able to completely extend their legs or stand totally upright has also been borne out and is accurate.

Vendramini notes ("Them and Us"):

And to top it off, German researchers who re-examined two Neanderthal spines (from Kebara 2 and Shanidar 3) in 2008 reported that both individuals displayed kyphosis—they were hunchbacks. This was most unexpected and, what’s more, their hunched backs weren’t the result of injury, disease or old age. The authors, Jochen Weber and Carsten Matthias Pusch believe the condition was part of their natural anatomy."

The story we'd read previously was that the hunched posture which Neanderthal skeletons had indicated in the past were due to arthritis and old age; that theory seems to have been blown up, i.e. the hunched posture was best possible for an ape seeking a hands-free lifestyle.

How do scientists assess the lowly ‘corn’ on the path of human evolution?

My experience has been that the development of ‘corns’ on hominids who began to walk upright should have created an evolutionary tendency to grow wings and eliminate walking altogether.

Well, maybe they’re proto-cillia and your descendants will be able to breeze along like a centipede in a couple hundred million years if they keep the faith and continue to select mates who also have proto-cillia.

Rest assured, all that awkward flopping around in a few million years is just a phase. Do not be deterred. Good things come to those who wait.

Y’all’ll be zooming around, up walls and over tough obstacles in no time, in the greater scheme of things.

Are you kidding? Can you imagine a millipede with millicorns?

The species would die out do to suicide, probably self-immolation into a volcano.

Facts are of no consequence to a zealot with an agenda!

Oh, now. That’s not a very positive outlook.

Just keep thinking of the advantages it confers. That’ll tide you over.

Maybe there was only one, in which case, a unicorn. But no one sees those without a drinking binge.
