Perhaps at the point of language? Afterall, there would have to be a "word", a command that tells them not to do something. Even if God communicated to Adam in thought, it would mean that an idea is transferred from one mind to another. The Fall happened after Adam started naming all the animals. Which is why...
...even if there wasn't written rules, there was an Oral Torah.
Well, that's just it, how much rational thought goes in to developing language? Birds have a language, bees have a language, apes have a language, whales have a language. It might not be in a form that humans today typically recognize...but look at the horse and dog whisperers, they "understand" the animal language because they take the time to study and translate it. But this is not commonly accepted academically. Instead, academia tends to "force" or "train" other creatures to use modified human language. Koko the gorilla is one example, using human sign language. Kanzi I think is the name of another ape, bonobo?, that uses modified sign. Dolphins and parrots have also been taught to use modified human language. But it is important to note that animals have a limited capacity when it comes to understanding time. Time is largely irrelevent to them, when one looks at transcripts of conversations with these animals. They sense the now, “in the moment,” and to a lesser degree the past, especially experience. They remember, but they can't really project forward in time, certainly no more than a few minutes. This projected forward thinking is something remarkably unique to humans.
So to simply say "language is the threshold" is not specific enough to delineate a border, a point in time when "we" shifted from being animals to being humans with rational thought, understanding, comprehension. Spoken language narrows the field a bit, but then you encounter some controversy regarding the development of the hyoid bone and its role in speech...as in "did Neandertals speak?" There is a bit of banter back and forth among anthropologists about this, as I am sure Path can explain better than I. Written language came much too late to account for the emergence of thought...we had pretty obviously been thinking heavily long before then.
I would be pressed to give specific names of researchers, but I have read things over the years that point to certain milestone moments in human development that demonstrate an ever increasing use of thought, forethought, and reasoning. Some animals in rare demonstrations show this in limited ways...Tao has pointed in the past to observations done with crows that were pretty cool, using tools. Chimps are known to make and use very simple tools, like a stick maybe chewed on one end to scoop up termites or something. But it is exceptionally rare to see any other creature except humans deliberately go out of their way for a specific resource, like maybe a type of stone (flint or obsidian), and bring it back and work it into a tool and use it. Or make a tool somewhere else and carry it to the jobsite to do whatever.
Now, the use of fire according to some I have read dates back nearly 200 thousand years, but at that time they were using natural fire. It is supposed that humans figured out ways to carry fire with them, probably with something like what Native Americans would use, which I cannot accurately describe but I am aware of the use. Making fire, on the other hand, involved specialized skills and tools that had to be developed over time. But those I have read on this say that didn’t occur until fairly recently, I think it was about 20-30 thousand years ago. Ten thousand years is a big span, but I’m going by memory here and its been a little while since I looked at this. This would place it squarely in the period of time when those gorgeous cave paintings in Lascaux and elsewhere were being done. Associated with the cave paintings, at least in some caves, is evidence of ritual and ceremony. There are other artifacts that coordinate with these things, carved venus figures and lowenmensch. But all of this is relatively late.
The use of ocher body paint dates at least as far back as 80-90 thousand years ago, as well as carved and worked ostrich shell decorations and fishings tools, between the Quafez Israel and Blombos Cave South Africa finds. Even Australia enters the picture quite early, Lake Mungo dates something like 60-70 thousand years ago…and how did he get to Australia over the ocean?
I find it all very interesting…but it is too complex to put a finger on one specific point in time and say “yeah, that’s it!” Neandertals get into the act…just how “human” were they? They certainly don’t quite qualify as the “Nephilim” as described in the Bible, yet there is evidence they were able to interbreed with Cro Magnon (our ancestors). Which raised more than a few eyebrows, and no doubt spurred on the current catalogue of the human genenome, which so far shows that Neandertal genetics did not survive into the modern era. (Or if it did, it’s a closely held secret) But Neandertals had bigger brains and were more robust than the gracile humans that came out of Africa and took over the world. But the Neandertals had an awkward thumb anatomy that limited their ability to use handled tools. The taller, likely more nimble and better armed (clubs and spears) Cro Magnon eventually superceded the Neandertal; whether by war, attrition or both is unclear.
This is why I say it is difficult to pinpoint a precise moment in time when we can say rational thought dawned on humans. But it is clearly evident that at some point in all of this rational thought did develop.
Anything you want to add, Path? Did I hit the high points?
