Fossil find pushes human-ape split back millions of years
Breitbart ^ | 8/24/07 | Mikey_1962

Ten million-year-old fossils discovered in Ethiopia show that humans and apes probably split six or seven million years earlier than widely thought, according to landmark study released Wednesday.

The near total absence to date of traces on the continent of apes from this period had led many scientists to conclude that the shared line from which humans and living great apes emerged had taken a long evolutionary detour through Eurasia.

But the study, published in the British journal Nature, "conclusively demonstrates that the Last Common Ancestor (of both man and ape) was strictly an African phenomenon," commented paleoanthropologist Owen Lovejoy of Kent State University in Ohio.

Lovejoy described the fossils as "a critically important discovery," a view echoed by several other scientists who had read the paper or seen the artifacts.

"This is a major breakthrough in our understanding of the origin of humanity," Yohannes Haile-Selassie, a physical anthropologist at the Cleveland Museum of Natural History, told AFP.

The most startling implication of the find, the scientists agree, is that our human progenitors diverged from today's great apes -- including gorillas, orangutans and chimpanzees -- several million years earlier than widely accepted research based on molecular genetics had previously asserted.

The trail in the hunt for physical evidence of our human ancestors goes cold some six or seven million years ago.

Orrorin -- discovered in Kenya in 2000 and nicknamed "Millennium Man" although its sex remains unknown -- goes back 5.8 to 6.1 million years, while Sahelanthropus, found a year later in Chad, is considered by most experts to extend the human family tree another one million years into the past.

Of course they have not meet my brother in law; his break from the Great Apes is much more recent.

YEC INTREP

Maybe they were never joined...and this is further proof.

Amazing how these estimates keep getting pushed further and further back in time.

Posts on the previous thread are numerous, insightful, and exhaustive.

"Amazing how these estimates keep getting pushed further and further back in time."

Definitions of estimates on the Web:

Estimation is generally an approximate or uncertain calculation of a result, often based on approximate, uncertain, incomplete, or noisy data.

An estimated reading is based on actual past use, seasonal trends and weather. Any difference between the estimated reading and the actual one will be made up the next time the meter is read.

Not really. That's the beauty of science : the more you research something, the more you find out, and the more accurate your data becomes.

There is a lot yet to be discovered but sadly most have bought into the fiction of humans and apes being 98/99% genetically identical. It just isn’t true even the number of chromosomes are different and the epigenetic code which controls how genes are expressed are highly different. Even Mice and humans share 99 percent of the same genes if you don’t consider epigenetics. Most creatures share genes from a common genetic tool kit. The genes are equivalent to functions used in programs. The epigenetic code is the control code and it is what makes a mouse a mouse, an ape an ape and a man a man.

And what makes tigons, ligers, zorses, geeps and other weird combinations?

I referred to the Gnostic heretics. Actually, one of their posts is exhaustive.

Here is the abstract of the article:

With the discovery of Ardipithecus, Orrorin and Sahelanthropus, our knowledge of hominid evolution before the emergence of Pliocene species of Australopithecus has significantly increased, extending the hominid fossil record back to at least 6 million years (Myr) ago. However, because of the dearth of fossil hominoid remains in sub-Saharan Africa spanning the period 12–7 Myr ago, nothing is known of the actual timing and mode of divergence of the African ape and hominid lineages. Most genomic-based studies suggest a late divergence date—5–6 Myr ago and 6–8 Myr ago for the human–chimp and human–gorilla splits, respectively—and some palaeontological and molecular analyses hypothesize a Eurasian origin of the African ape and hominid clade. We report here the discovery and recognition of a new species of great ape, Chororapithecus abyssinicus, from the 10–10.5-Myr-old deposits of the Chorora Formation at the southern margin of the Afar rift. To the best of our knowledge, these are the first fossils of a large-bodied Miocene ape from the African continent north of Kenya. They exhibit a gorilla-sized dentition that combines distinct shearing crests with thick enamel on its 'functional' side cusps. Visualization of the enamel–dentine junction by micro-computed tomography reveals shearing crest features that partly resemble the modern gorilla condition. These features represent genetically based structural modifications probably associated with an initial adaptation to a comparatively fibrous diet. The relatively flat cuspal enamel–dentine junction and thick enamel, however, suggest a concurrent adaptation to hard and/or abrasive food items. The combined evidence suggests that Chororapithecus may be a basal member of the gorilla clade, and that the latter exhibited some amount of adaptive and phyletic diversity at around 10–11 Myr ago.

Note the many qualifiers, as well as the difference between the abstract and the article above.

The epigenetic code of course controlling the expression of genes. The interesting thing about the epigenetic code is that it is effected by ones behavior providing a genetic feedback loop.

I think it is far from coincidence that socialist secularists have such a need to minimize the difference between man and animal even though such differences are so readily apparent to be undeniable by anyone who has not been hypnotized to ignore them. They need a population who believe themselves and others incapable of doing what is good for themselves without help. They need a population so focused on base needs of sex, food, and entertainment that they can be controlled by regulating the levels of each of those things. Teaching the lie of indistinctness between man and common animals is a way to further that goal.

The last thing they need is a good of people believing in the ascendancy of man with people able to rise above their base desires. They instead what a population of fools totally dependent on the creators and controllers of the bureaucracy.

Well, that's impossible. The earth is only 6000 year old....

Irrelevant. There are horse breeds with different numbers of chromosomes, and they can successfully interbreed, demonstrating that their DNA is very compatible.

Because the evidence doesn't support the conclusion the poster has drawn from it. Humans and apes split earlier than previously thought, therefore humans and apes never shared a common ancestor? That doesn't seem sound logic to me. So that's what I indicated in my post.
