Skip to comments.Ancient Foot Suggests How Man Gave Up Treehouses
Posted on 03/31/2012 11:33:41 AM PDT by SunkenCiv
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.

To all -- please ping me to other topics which are appropriate for the GGG list.The 3.4-million-year-old fossils were discovered in 2009...That means they're 3,400,003 years old now.
I only gave up treehouses because there aren’t any trees on my property strong enough to support them. Rope ladder maintenance is another consideration . . .
What I’d like to know is how many evolutionary events define the transition from this “pre-human species” to the human species.
And what were the specifics of the genetic mutations forming these evolutionary events?
Some people in Santa Cruz are still living in tree houses.
oh that makes it so much clearer
Not that really does make it clearer....they came out of ‘tree houses’ for the Colonel’s finest. :)
Looks like a bone from modern day man both in size and structure. I would doubt that this bone was part of a foot with opposable great toes.
It’s all speculation. A clear fossil record exists for everything but the evolution of man as described by those who believe we descended from apes.
It’s like global warming. The evidence does not support it but they latch onto any event they can or distort the facts to fit their belief.
“send grant money”
So correct. It’s about grant money and supports the attack on religion and promotion of socialism.
Oh hell, I threw those chicken bones down a few months back when I was hiking through Ethiopia. A fellow has to eat something.
I used to spend some pleasurable time here in the mid-late 60's.
Based on some of the other replies, apparently those tree houses have broadband.
Once upon a time, long, long ago..........
That's one of Wiki's pages dealing with Neanderthal anatomy. It shows a mockup of a complete Neanderthal skeleton with normal looking feet which are probably just concocted from minimal real evidence as usual, and then an image of a Neanderthal footprint which is presumably real and a caption describing it as from the Natural History Museum in Prague:
THAT is pretty obviously an ape's footprint. You could view that image as an artifact of a human-like Neanderthal having once had a pet gorilla; I view it as an artifact of people looking at something the wrong way.
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.
partly because walking upright frees their hands for tool use
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.
Caption reads "From the American Museum of Natural History">
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.
They probably got tired of falling out of bed in the morning......
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.
Gorilla male foot:
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.
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 kyphosisthey were hunchbacks. This was most unexpected and, whats more, their hunched backs werent 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.
Gotta call em like I see em!
Great job countering agenda driven delusion with facts!
Maybe there was only one, in which case, a unicorn. But no one sees those without a drinking binge.
:’) Thanks again.
