A blackened, broken leg bone from Earth’s prehistoric past may hold the answer to when early humans diverged from apes and started their own evolutionary path.
The fossilized find, first uncovered two decades ago, suggests that early humans regularly walked on two feet some seven million years ago... Since many consider bipedalism the major milestone that put our own lineage on a different evolutionary path than the apes, Sahelanthropus could be the very oldest known hominin—the group consisting of modern humans, extinct human species and all of our immediate ancestors.
The species could even be our oldest non-ape ancestor, if its lineage led to Homo sapiens instead of dying out. But while the fossil femur appears to have supported the demands of habitual upright walking, Sahelanthropus’s chimp-like forearms show that it still spent plenty of time in the trees. Two surviving arm bones reveal that the species used a grasping climbing technique to support a type of hybrid lifestyle that could have persisted among early hominins for some three million years...
Boisserie and colleagues, some of whom originally described Sahelanthropus in 2002, compared more than 20 traits of the femur and forearm bones with a large sample of living chimpanzees, gorillas and orangutans, fossil Miocene apes, early hominin bipeds like Orrorin tugenensis and Ardipithecus Ramidus, and remains of prehistoric Homo and Homo sapiens. They compared external shapes, curves, internal structures and thicknesses to learn if the bone had the same characteristics as those known to be well-suited to the demands of force, balance and other requirements of upright walking. The femur of S. tchadensis showed many similarities with other hominin species, while no traits of the femur were also found exclusively in apes.

Adam was formed from clay.
God breathed life into Adam.
His wife Eve God formed from one of Adam’s ribs.
How does any of this square with your theory of Adam coming from lower order primates?
As LLCoolJ used to say, FS: Check yourself before you wreck yourself.
Oprah however, may leave the Jury with a slight doubt!!
There’s an image of what the monkey
—
Ape, not monkey- 2 different animals.
Damn Global Warming!............................😁
Of course the original Sahelanthropi tchadenses were probably more intelligent.
Yeh sure. 🙄
this adds to suggestions/evidence that the ancestor of humans chimps and gorillas walked upright....that only subsequently did gorillas and then chimps fall forward to their knuckles.
This may have happened somewhere in the sahel of africa where forests and plains pretty regularly supplanted each other
That’s awfully closed minded of you.
It’s science, actually. Entirely consistent with Christianity.
Please see my #61.
And consider doing likewise.
Check out post #61 and ditto from me as well. The human race has NEVER evolved but we have de-evolved. We’ve degraded and that, my friend, IS science.
Not monkeys, great apes.
Here are other images:
familyop: "Did sometimes walking on two legs make it human?"
Not humans -- not homo sapiens, not even the genus homo -- i.e., Australopithecus, Homo Erectus, Homo Neanderthalus, etc. -- but potentially hominins, meaning ancestors back to the point of divergence from other great ape species.
Thanks BroJoeK.
Most people, it seems, don't remember a lot of things they should have learned in school.
Not 100% sure just whose fault that is...
:^)
Those are officially known as "Scientific Wild-*ssed Guesses" -- SWAGS, for short.
Swags are essential to the scientific process -- they come before confirmed theories, before scientifically stated hypotheses, they've been called "brain storming", wherein a scientist considers all potential explanations.
Work on fossils like Sahelanthropus tchadensis typically includes a mixture of observed facts, confirmed theories, falsifiable hypotheses and, yes, some imaginative Swags.
Scientific writings are supposed to clearly distinguish which of those it's referring to.
Evolution is all about "minor tweaking" -- randomly turn on a gene here, turn off one there, mutate an allele, minor adaptations, generation after generation, over millions of generations can accumulate into major changes in forms & functions.
That's evolution in a nutshell.
The Bible and science 100% agree that God started with mud and ended by breathing His spirit into man.
The Bible doesn't tell us what all steps God took between start and finish.
Science figures there were quite a few steps, beginning with: how do you create mud?
“Evolution is all about “minor tweaking” — randomly turn on a gene here, turn off one there, mutate an allele, minor adaptations, generation after generation, over millions of generations can accumulate into major changes in forms & functions. That’s evolution in a nutshell.”
Given enough time and faith stuff happens and an amoeba can evolve into a human being. Sure. :-)
