BigBamaQ: I would very much like to see source material for this 100,000 year gap you profess. having done a great deal of study in the area of mans evolution of tools. I have never heard this claim made.
BigBamaQ - I am very sad to learn either Albama lacks Internet, or you don't know how to Google a topic..
Nevertheless, I would suggest this website as a start.
From it, ".., and gave rise to anatomically modern Homo sapiens in Africa about 200,000 years ago. They began to exhibit evidence of behavioral modernity around 50,000 years ago..."
from it, "Omo I and II (195,000 years ago): In 1967, a team led by Richard Leakey discovered possible Homo sapiens fossils in the Kibish Formation near the Omo River in southern Ethiopia. Originally the fossils, Omo I (a partial skull and skeleton) and Omo II (a partial skull), were thought to be 130,000 years old, but a dating reanalysis in 2005 revealed they were much older—195,000 years old, making them the oldest fossils assigned to Homo sapiens. Over the last 45 years, the species status of the fossils has been debated. Researchers largely agree Omo I was a modern human; it had the human hallmarks of a flat face, fully formed chin, high forehead and globular braincase. They are less certain about Omo II, which was more primitive with its thicker, more “rugged” cranial bones and sloped forehead. While some paleoanthropologists say Omo II is too archaic to be one of us, others suggest it’s evidence of the great physical diversity of early modern humans."
There is much more for you to find. The old thoughts of 20 or 40 years ago are now obsolete. Biggest puzzle I see, as the OP shows, is tools and making tools predate us. We shared the planet with other Homo species (Hablis, etc.). They used tools. But no trace of tools has ever been found with human remains more than 100,000 years old. At about 100,000 years ago, suddenly our ancestors decide it is good idea to copy the other guys.
That either makes perfect sense to you (but not to me), or there is a huge amount we know nothing about covering our first 100,000 years and what happened to the first civilizations of which we find no trace. Tools start appearing with our remains at 100,000 years ago. Trace civilizations (communities) at 50,000 years ago. Agriculture at 7,000 years ago. No explanation to explain why we spent the first 100,000 years of our lives, sitting with our thumbs up our butt, while all around us Cro-Magnon, Neanderthalus, Hablis, and all the others were in communities, using tools, and making fires and cave paintings. WTF were we doing back then, eating psychedelic mushrooms and begging food from the ape men?

It would seem logical to me that what anthropologists consider, or considered, Homo Sapiens 200,000 years ago wasnt entirely correct. While cross species breeding apparently took place , neanderthal and sapiens etc., the ability to produce offspring is usually the primary test to determine a species. No offspring with breeding = different species.
Apparently then, our unique intellectual abilities developed independently of any species identification. It could of been angels or aliens, but I suspect a subtle mutation in the grey matter 100,00 years ago in a lower intellect ape! HA! HA!

Well regarding the first, it seems the anthropologists are pretty convinced the Homo Sapiens today is the same as the Homo Sapiens back then. Quite simply if they felt otherwise they would have assigned a different species name to the 200,000 year old bones. Noting also, initially they didn't realize how old those bones were until retesting with more accurate machines was done in 2005.
I am open to the concept of an external event (i.e., mutation, virus DNA being incorporated into our own, etc.) increasing the efficiency of the gray matter 100,000 years ago, but the skull's internal cranial cavity size remained constant, and that argues against it.
I see two choices. We used tools and had communities back then, but all evidence of that was carefully not buried with our bones (the who and why of that is of course unknown). Or, we developed just as we did in the second 100,000 years, but we had a major catastrophe of some kind erase all evidence of it. Even buildings of iron and concrete, and automobiles would vanish with all traces being absorbed by the earth after 100,000 years. Wild speculation I agree.
Yes, clearly we took what mates were DNA viable. Maybe even a few that weren't. Lucy may have looked pretty good with a whole body shave. LoL.
it is very hard to find stone tools from a million years ago especially from the few humans running around. we simply don't dig so much around. and good settlement place have obviously been settled.
To think that man (or his antecedents) can be the only tool user is pretty lame. I suggest walking away from your screen and go outside. Watch some birds. Challenge some ants. Give a dog an opportunity. He'll use one. Cats are just not that creative IMHO. (ducking the inevitable fame war) Then come back to your screen and look up critters like dolphins and various apes.

Report back here.
Lots of animals use tools.
Maybe I assumed too much, by not checking to make sure the tools they found weren't twigs used by monkeys to gather termites...
I just don't believe that would be newsworthy.
How many birds, monkeys, and dolphins are adept at chipping rocks into knives, adzes, arrow heads, and spear heads?
Actually, stone tools are known to have been used in Neolithic times for surgery; and they're still used in surgery today...
Polynesians were stone aged people, until recently; and they're the best sailors on earth.
So... stone tools place very little limits on some of what we consider, "modern technology."
How Stone Age blades are still cutting it in modern surgery By Peter Shadbolt for CNN
(CNN)Ever had a headache so big, you felt like drilling a hole in your head to let the pain out?
In Neolithic times, trepanation -- or drilling a hole into the skull -- was thought to be a cure for everything from epilepsy to migraines. It could even have been a form of emergency surgery for battle wounds. But while there is still conjecture about the real reasons behind the mysterious procedure, what is known is that the implement often used to carry out the primitive surgery was made from one of the sharpest substances found in nature: obsidian. Cutting edge Obsidian -- a type of volcanic glass -- can produce cutting edges many times finer than even the best steel scalpels. At 30 angstroms -- a unit of measurement equal to one hundred millionth of a centimeter -- an obsidian scalpel can rival diamond in the fineness of its edge. When you consider that most household razor blades are 300 to 600 angstroms, obsidian can still cut it with the sharpest materials nanotechnology can produce. The worms that invade your brain Even today, a small number of surgeons are using an ancient technology to carry out fine incisions that they say heal with minimal scarring. Dr. Lee Green, professor and chairman of the Department of Family Medicine at the University of Alberta, says he routinely uses obsidian blades.
