"The first calculations of the age of the calendar were made based on the rise of Orion, a constellation known for its three bright stars forming the "belt" of the mythical hunter."
" But new and more precise measurements kept increasing the age. The next calculation was presented by a master archaeoastronomer who wishes to remain anonymous for fear of ridicule by the academic fraternity. His calculation was also based on the rise of Orion and suggested an age of at least 75,000 years. The most recent and most acurate calculation, done in June 2009, suggests an age of at least 160,000 years, based on the rise of Orion -- flat on the horizon -- but also on the erosion of dolerite stones found at the site."
"you'd need to know exactly how fast that particular stone eroded, wind speeds over time, a bunch of stuff."
"Some pieces of the marker stones had been broken off and sat on the ground, exposed to natural erosion. When the pieces were put back together about 3 cm of stone had already been worn away. These calculation helped assess the age of the site by calculating the erosion rate of the dolerite."
I honestly wouldn't be completely satisfied unless there was a signed, "born on date".
...maybe I'll go read the rest of that link..
What's your opinion about the dating method they're primarily using? The precession method.

But we got to go with what we got, and always be willing to let the evidence lead the way.
Your right to be skeptical. I'm really interested in the mining site, and what evidence, and or theories that come from it.
It's supposed to be the largest deposit of gold on Earth, according to claims.
Actually this is not true. Evolution occurs all of the time, necessity has nothing to do with it as it is an undirected process. Modern apes have evolved just as much as we have. We are not evolved from modern apes but from a common ancestor between us and chimpanzees. Even so, the original question creates more than one misconception. It is like asking that if Americans descended from Europeans, why are there still Europeans? Evolution often can produce more than one species from a single basal form and unless the original goes extinct, they all can co-exist contemporaneously."(why are there still apes on this planet if we descended from them)"
Evolution is out of necessity, not just something that happens for no reason. Those apes in particular never had a reason to evolve like us.
It's a bit redundant I guess, lol.It is my opinion that with no variation there is no evolution, having said that variation happens all the time and probably wont ever stop. BTW the ape thing was @ mindphuk Good post +rep
is co-exist not the definition of contemporaneous?
It's strange to me that people that deny ''macro' evolution cannot offer up any explanation as to what prevents 'micro' evolution to continue to the point that it is considered macro, i.e. creates new species. They put up an artificial barrier and cannot explain what creates that barrier, what exactly prevents a new species from forming.The various Ensatina salamanders of the Pacific coast all descended from a common ancestral population. As the species spread southward from Oregon and Washington, subpopulations adapted to their local environments on either side of the San Joaquin Valley. From one population to the next, in a circular pattern, these salamanders are still able to interbreed successfully. However, where the circle closes -- in the black zone on the map in Southern California -- the salamanders no longer interbreed successfully. The variation within a single species has produced differences as large as those between two separate species.
Extinction events play a major role in diversification because of the radically changed environment changes the fitness of almost all species. Extinction events give us the best chance to see major changes in the fossil record. The thing is, science doesn't really recognize the distinction between 'macro' and 'micro' evolution as it is all a continuum. It is the creationists and IDers that have defined macro as evolving a new species. The problem is that even though they defined it, when we show them examples of such evolution, they still deny it is macro. They have a bad habit of continuing to move the goal posts.I thought that it is at the time of or near Extinction that evolution occurs.Macro.
