An international team of scientists unveiled Thursday the results of 15 years of study of one of the oldest known human ancestors, Ardipithecus ramidus, which they say overturns much of what we know about human evolution.

And surprisingly, it's also rewriting the story of our relation to gorillas and
chimpanzees, our closest living relatives, and their development as well.

The depiction at the beginning of Ron's OP was the banner on the front cover of the July 23, 2001 issue of Time magazine and claimed that a new hominid discovery tells "scientists about how our oldest ancestors stood on two legs and made an evolutionary leap." Yet those empty cover-words become almost secondary as readers find themselves captivated by that "ape-man" drawing that blankets the entire cover. So, that pretty little depiction is not the "result of a 15 year study", it is what some staff writers dreamed up.

And on page 57 of that issue of Time, staff writers Michael Lemonick and Andrea Dorfman admit that the discoverers of the fossils under discussion, Yohannes Haile-Selassie and his colleagues, "haven't collected enough bones yet to reconstruct with great precision what ardipithecus ramidus looked like." That fact, however, did not prevent the magazine's editors from putting an intimidating, full-color spread of this new creature on the cover - an image that becomes somewhat laughable in light of the actual facts.

A thorough investigation of this "scientific discovery" reveals that this creature was "reconstructed" from only 6 bone fragments (and a few teeth) - of which, the only bone that might provide the artist with any structural information of the head is a piece of the right mandible.

In the article, "One Giant Step for Mankind," the reader is invited to "meet your newfound ancestor, a chimplike forest creature that stood up and walked 5.8 million years ago" (p. 54).

It goes on to comment, "No one has yet been able to say precisely when that first evolutionary step on the road to humanity happened, nor what might have triggered it. But a discovery reported last week in the journal Nature has brought paleontologists tantalizingly close to answering both these questions".

That’s a pretty tall statement, considering the fact that researchers had only the following bone fragments to discern all of this information: fragment of the right mandible, one intermediate hand phalanx, left humerus and ulna, distal humerus, proximal hand phalanx fragment, left clavicle fragment, proximal foot phalanx, and a few teeth.

Additionally, these bones were not laid out neatly in typical skeletal format, all grouped together just waiting for researchers to dig them up. No indeed. These few bones took researchers 5 years to collect, and came from 5 different locations!

And so, from a fossilized toe, a piece of jawbone, a finger, arm bones, a clavicle, and a few teeth we have this incredible "ape-man" telling us "how apes became human." From small fragments we are shown this as a conclusion:



:scratch: - :roll:

Prominently displayed in the center of page 59 of In the article is a tiny fragment of a toe bone and its the staff writers, not the scientists who write: "This toe bone proves the creature walked on two legs."

Amazing, is it not, what one can discern from a single toe bone! The human foot contains 26 individual bones, and yet evolutionary scientists claim that they can distinguish walking characteristics from just a single bone?

That bold caption also fails to inform us that this toe bone was found in 1999, is "chronologically younger" than the other bone fragments, and was found in a separate location from the rest of the fossils.

In fact, the bone fragments that make up this new specimen came from five localities of the Middle Awash in Ethiopia: Saitune Dora, Alaya, Asa Koma, Digiba Dora, and Amba East (Haile-Selassie, 2001,).

The staff writers, Lemonick and Dorfman admitted, "Exactly how this hominid walked is still something of a mystery, though with a different skeletal structure, its gait would have been unlike ours" (p. 57). But that did not stop the authors from speculating that "Ardipithecus ramidus almost certainly walked upright much of the time" and that "many of its behaviors undoubtedly resembled those of chimpanzees today" (p. 57).

Interesting speculation, especially in view of the fact that the ages of the fossilized bone fragments composing ardipithecus ramidus vary by hundreds of thousands of years, even using the evolutionists' own dating schemes.

In contemplating the origin of "two-leggedness," the authors of the Time article suggested that these animals were rewarded with additional food for their bipedal mobility. The writer then go into painstaking detail to describe the environment in which researchers believe these creatures lived - an environment that, in their view, necessitated that animals walk upright.

Meave Leakey, head of paleontology at the National Museums of Kenya, wife of Richard Leakey, a well known member of the world's most famous fossil-hunting family, stated: "And if you're moving into more open country with grasslands and bushes and things like this, and eating a lot of fruits and berries coming off low bushes, there is an advantage to be able to reach higher. That's why the giraffe evolved its long neck" (p. 59).

Yet even staunch evolutionists such as Stephen Gould cringe at statements like that. In fact, in an article titled "The Tallest Tale", Gould began by stating, "The tallest tale is the textbook version of giraffe evolution - a bit of a stretch." Gould went on to state:

"Giraffes, we are told, got long necks in order to browse the leaves at the tops of acacia trees, thereby winning access to a steady source of food available to no other mammal. Lamarck, the texts continue, explained the evolution of long necks by arguing that giraffes stretched and stretched during life, elongated their necks in the process and then passed the benefits along to their offspring by altered heredity. This lovely idea may embody the cardinal virtue of effort rewarded, but heredity, alas, does not operate in such a manner. A neck stretched during life cannot alter the genes that influence neck length and offspring cannot reap any genetic reward from parental striving" (pgs. 19-20).

In commenting on why this example of evolution with the giraffe's neck is bad science, Gould wrote:

"If we choose a weak and foolish speculation as a primary textbook illustration (falsely assuming that the tale possesses weight of history and a sanction in evidence), then we are in for trouble as critics properly nail the particular weakness and then assume that the whole theory must be in danger if supporters choose such a fatuous case as a primary illustration" (p. 56).

I.D.er Luther Sunderland further reiterated the foolishness of this line of thinking when he stated: "Evolutionists cannot explain why the giraffe is the only four legged creature with a really long neck and yet everything else in the world without that long neck survived. Many short necked animals, of course existed side by side in the same locale as the giraffe" (1988, pp. 83-84).

And so, as Leakey herself pointed out, the evolutionists theories regarding bipedalism "are all fairy tales really because you can't prove anything" (Lemonick and Dorfman, p. 60). Fairy tales indeed!

While Ardipithecus ramidus kadabba undoubtedly will stir controversy among evolutionists as to exactly where it fits into the "evolutionary family tree," it does little to answer the questions of "how apes became human," or when and why these creatures became bipedal.

Given the small measurements of the fossilized bones collected, ardipithecus ramidus kadabba is very likely to find itself relegated to the same branch as the infamous Lucy (Australopithecus afarensis) - simply a fossilized ape.

Real science a problem for us? I don't think so.
It's not clear what position you're taking on this. You've posted a lot of criticism of the report, and of course there will be legitimate criticism, that's the nature of science. However, if your actual position is anti-evolution, or you think the earth is less than 10,000 years old, or something like that, then yes, real science is a problem for you. Evolution is a fact, the earth's about 4.6 billion years old, and that's the way it is.

Yes. Beyond any reasonable doubt, the evidence is overwhelming and incontrovertible. It's a fact as firmly established as the fact that the earth orbits the sun.

Read Ernst Mayr's What Evolution Is, and Richard Dawkin's latest, The Greatest Show on Earth. They are about the evidence for evolution, and if they don't convince you, you are one of the following:

1. too stupid to understand
2. in denial for religious reasons
3. insane

I vote for number 2 and possibly number 3 because of number 2.;-)

They simulated a meteorite impact useing dust from space and when it hit the simulated ocean what was created by the impact was amino acids,the building blocks of life.

I've always had a hard time with this concept as it relates to our species, it implies that we evolved in the water as some kind of fish then came out onto the land and evolved into some kind of monkey then got smart enough to build todays modern civilization,it would be more believable if at least a few other of the hundreds of thousand of species had also developed beyond basic animal intellect and got to the point where they also could understand the concept of "i think therefore i am"
I'm not buying it.

It doesn't imply that at all, it states it directly, and it's demonstrably true, though it's a little inaccurate to say "some kind of monkey." We are not descended from monkeys, we share a common ancestor with them. The evidence is perfectly clear if you have the wit to understand it. We also share a common ancestor with all mammals, with birds, with fish, with every living thing. All living things are related.

Dont take it by that post that i'm a creationist i'm evolution all the way i just find it hard to figure out why only the human species developed intelligence, other species had it just as hard when it came to adapting to their environment but they dont even comes close to exhibiting more brain power now than they had a billion years ago.

Other species specialized in different ways. We for instance don't have better eyesight than most creatures. Heck, might even be worse than some of our close ancestors.

Brain power is the same thing, a specialization. No organism has all of the known specializations. We create a special kind of organism though. Needs for humans are not the same as needs for an orca. Our brain is special. But so are all specializations that evolution yields.

That is the point Dexter; nobody has really offered an alternative theory to evolution. Creationism or Intelligent Design are not scientific theories, they are superstition.

There is no alternative to evolution. If by some chance evolution is proved false in the future (and it is a scientific theory, it is capable of being disproved), it will be back to the drawing board, to try to come up with a new theory. But that no way implies that scientists will accept Creationism or Intelligent design.

That is not true, jambo, Mother Nature tried many different paths to intelligence. Many animals besides humans are highly intelligent, e.g. dolphins. They have a well developed language (I think they can produce up to 100 sounds). Unfortunately they took to water, where there is no need for intelligence. It was a dead end as far as nature was concerned.

Another path to intelligence was the elephants. Elephants are highly intelligent; they have excellent memory and can pass knowledge from generation to generation. Scientists have found instances of the Matriarch of the herd leading the herd to a water source in the time of famine, one which she has never seen before.

They have also observed elephants mounting fake raids. Two or three elephants would raid a farm, drawing the villagers after them, while the main herd invades a totally different farm.

Scientists also suspect that elephants perform some kind of ritual when they come across the bones of other elephants from the herd. They sniff at the bones, they circle around it, they walk around it.

Elephants also have a highly complex social structure. Elephants show most of the signs of intelligence, if on a smaller scale. African elephants have two fingerlike protrusions at the tip of their trunk (Asian elephants have only one).

It is not to hard to imagine elephants developing more of such protrusions, giving them fingers to work with. That would give them the ability to make tools. I personally think that three was a competition between elephants and hominids as to who develops intelligence first, and hominids won by a hair (a few million years). If humans had not developed intelligence for a few million years, it is not inconceivable that the world would be populated by intelligent elephants today. But once humans developed intelligence, it put a stop to any further evolution.

I don’t think there is anything unique about intelligence. Mother Nature tried many different paths towards intelligence, and one of them (hominids) succeeded. Another (elephants) could equally well have succeeded.

The one problem I see with that argument is the it is humans who define what is intelligence. Just because we cannot communicate with other species does not make them unintelligent. Many species, in particular, sea going mammals, have far greater brain capacity than we do. I look at dolphins and all they do is play, eat and have sex all day and I wonder who is the more intelligent. And they don't destroy their environment the way we do. I think our claim to intelligence is just one colossal ego trip.
