Stone Blades Cut Back Evolutionary Dates
by Brian Thomas, M.S.*
Evolutionary anthropologists once thought that stone knives were developed in the late Stone Age, around 40,000 years ago. That figure was later revised to 200,000, around the Middle Stone Age, when stone blades were discovered in lower strata.
Now stone blades have been found in Kenyan rock layers dated at about 500,000 years old according to evolutionary estimates.1 Thus, the original claim that “40,000 years ago, man made his first stone implements” was off by over 92 percent, suggesting that evolutionary depictions of human history are unreliable....

I believe those people had the same brain capacity as we do now. Just with few resources to go with. They had an idea to create what they needed. If you look around right now, everything we use are tools. All were made for our convenience. No matter what you use. Calculus by Isaac Newton for example simplifies calculations. Tools.
See also this article about Kanzi the chimp making stone tools. Part of the issue is how sophisticated the tool has to be before you call it a manufactured tool.
Meanwhile, the Creationists are still not explaining why there are no modern mammals or humans in the same geologic layers where we find dinosaurs, if we were all created in the same week.
Removal of multiple blades like that from a core of such coarse material requires a sophisticated knowledge of shock wave propagation and the ability to predict force vector resultants -- and very careful selection and control of the point and force of impact.
Such multiple blade removals simply cannot occur via any natural mechanism. They were performed by an intelligent and well-coordinated being.

Note how the charlatan, "Brian Thomas, M.S." attempts to cast the honesty of scientists who correct their knowledge base as better data is acquired -- as a "weakness" in their knowledge.
How charmingly smug of him to sneer at his intellectual superiors -- simply because his (and "Bishop" Ussher's) misinterpretation of a few words in Genesis has supposedly given him the "whole TRUTH".

The God who created this universe doesn't need such hucksters and hustlers "defending" Him.

He also hopes that he does not use the same tax account.
“Removing the restriction of long-age assumptions, the stone knives were most likely made somewhere on the order of several thousand years ago, at least since the time of the Tower of Babel, circa 2200 B.C. The forced dispersion of peoples from the Middle East outward across the rest of the world, as described in Genesis 11, caused migrating families to start from scratch, eking out an existence with stone knives and cave dwellings for a time. The volcanic deposits that sandwiched the newly-discovered African blades could well be remnants of post-Flood volcanic activity, marks of a time when earth’s crust was less stable, still settling down from the great, year-long upheaval of Noah’s Flood. This historical picture, unlike the standard evolutionary one, is based on eyewitness accounts, not on unfounded and ever-changing presuppositions.”
Unless I overlooked something I fail to see where Brian Thomas M.S.* provides any evidence to support this assertion.
Yes, and apes have no science. Nor do dolphins, I think.
Dump that search and get into aerospace. There are materials that need to be scoped out for real flaws created now.

That is "snide" -- and is the trademark style of the YEC writers.
Speaking of "misleading", the depiction of a well-crafted Clovis point
in reference to an article discussing rudimentary blade removals -- now, that is "misleading".
~~~~~~~~~~~~
"Snide?" Countering the snideness of the YECArticle was, indeed, my intent.
OTOH, I posted demonstrable (and replicable) facts. (Do you also need me to point out the [both positive and negative] conchoidal fracture remnants resulting from the 120-degree shockwave propagation?)
Please point out where I was "misleading"...
Yet apes make tools. Explain, please.
BTW. it is obvious that neither the author of the YEC website article nor the poster of this thread (if they are not one and the same) knows the difference between a blade and a biface.
“In the Brevia section of the 9 August 2002 issue of Science, Weir et al. report a remarkable observation: The toolmaking behavior of New Caledonian crows. In the experiments, a captive female crow, confronted with a task that required a curved tool (retrieving a food-containing bucket from a vertical pipe), spontaneously bent a piece of straight wire into a hooked shape — and then repeated the behavior in nine out of ten subsequent trials. Though these crows are known to employ tools in the wild using natural materials, this bird had no prior training with the use of pliant materials such as wire — a fact that makes its apparently spontaneous, highly specific problem-solving all the more interesting, and raises intriguing questions about the evolutionary preconditions for complex cognition. The crow’s behavior was captured on an unusual video clip, available on Science Online.

Crows are far more intelligent than their station in life would demand.
That is not the case. We experimental lithic technologists have reproduced blades like those shown, used them to cut both plant materials and meats -- and have then examined the microscopic edge wear (or "polish") with the SEM [Scanning Electron Microscope].
Our results match the wear on prehistoric samples very precisely. IOW, we can distinguish whether a prehistoric blade was used for cutting either vegetable material or meat. (FYI, plant cells contain minute particles of silica, [quartz sand] the difference between vegetable and meat wear/polish is dramatically obvious under sufficient magnification.)
FWIW, I am retired, and am doing what I enjoy now -- even if that entails "going back to the stone age" on occasion... '-)
No question. The film of the tool-making crow is absolutely remarkable.
I wonder if we'll ever see a rational discussion from the creationists on how the geologic fossil record has no modern mammals or humans in the same layer as dinosaurs.
Evolutionary anthropologists?
Please. They are simply anthropologists.
Creationists like to tack the word “evolutionary” onto anything they disagree with. It is a buzzword for their brain numbed followers so that they won’t actually have to think; and their objections to these people and their findings need not be explained or detailed other than to say that they are “evolutionists” and thus worthy of contempt to those with more spite and ignorance than knowledge.
Anthropologists are not specifically trained in evolutionary theory, neither did the theory of evolutionary biology in any way influence their data.
Rocks do not evolve by means of natural selection of genetic variation.
