Yes, it's well possible that tool use & speech co-evolved (late-Pleistocene?):
both find their origin partly in our Pleistocene shellfish-diving past:
-stone tool use for opening shells, cf sea-otters,
-voluntary breathing for shallow-diving,
-large brain thanks to seafood, e.g. DHA,
-lip-tongue-throat movemensts for suction feeding.

IOW, only incredible idiots still believe their ancestors ran after antelopes.

[Mario Petrinovic]

Stone tool use started in Pliocene, 3.3 mya the latest. Shellfish tool
use should predate that. Language should predate shellfish tool use.
They may evolve in unison, but, the above sequence of things should be
correct.
Further still, just like I am always saying, the difference between
Australopithecus and Kenyanthropus/Homo should be in language use. If
Australopithecus had language (it probably had), this language was very
undeveloped. It is coastal living that develops language to the level
that is necessary for the development of tool use.

Mario, Mario, Mario...

Dogs also have "language"...

[Mario Petrinovic]

Australopithecuses aren't dogs. In their evolution water was a major
thing, just like it was in our evolution. And water is excellent for
acquiring language, ask any seal.

Yes, Mario, yes... I meant, of course, dogs & most mammals make different kinds of sounds,
but that isn't language: apiths did NOT speak.

BTW (this has 0 to do with your nonsense about speaking apiths),
did dog domestication begin with cooperation between wading early H.sapiens, chasing e.g.ducks or waterdeer between reeds, & wolves waiting at the waterside?

[Mario Petrinovic]

Whenever I am thinking about dog domestication, I always look at
Gelada baboons and Ethiopian wolf.
I mean, we are natural partners. We eat meat, but we cannot eat bones.
On the other hand, dogs are excellent alarm devices. The are small
enough so they cannot harm a group of people (when dogs hunt, they
always single out one individual).
So you have a situation where you have a group of people, and a bunch
of bones around them. And dogs come, and eat those bones. They are not
offensive, and they are great alarming devices, so why not secure them
around by leaving some meat on those bones?
Similar thing with cats, when humans started to stock cereals, a lot
of mouses moved around it. After mouses cats came. Just the other day a
neighbor cat left a dead mouse in front of my door. Maybe she wanted to
establish some kind of bond, she catches mouses for me, while I feed
her. It is good for times when there are no cat food around, so that I
can provide her with a food all year around.
So, this "domestication" can happen when we started to eat terrestrial
meat, with ease. I mean, how dingos came to Australia? On a cruise ship?

When do stick tool use begin? All hominoids use stick tools. Some use stone tools.

Language should predate shellfish tool use.

Just like sea otters & parrots! Wait...

Imagine that.

[Mario Petrinovic]

Stone tools have sharp edge. This is like broken shellfish. So, the
main thing in stone tools isn't to be used as a hammer. Stone (unmade,
raw) can be used as a hammer, you don't need stone tool for that. Stone
tools are made to be used as a cutting device.
The paradox is that for cutting (sharp edge), you need to have sharp
edge. So, the idea originated in the usage of sharp edges. But, the
Oldowan tools are made out of pebbles, and pebbles are about the
bluntest objects in nature, not the sharpest. So, the development of the
usage of sharp edges should happen before Oldowan stone tools.

No way. Which materials?
Antlers? With antlers you can pierce. But, what's the use of piercing?
If you don't have carnassials you cannot eat what you pierced.
Shearing. Stone? It will break your teeth? Obsidian? It will cut your
throat. Metal? Now, that's much better, but it only came in Middle
Paleolithic, along with Homo sapiens. This is why Homo sapiens has
changes in chopping apparatus. With metal we chopped off meat from
carcass. But, that's about it.
No, before the first tools, we had to have fire. Fire was the tool to
soften up meat. Why would you pierce an animal, if you cannot eat its
meat? For hides? No. Before Oldowan tools we had to have fire,
otherwise, why would we hunt animals in the first place?
And this logical net *proves* how Science is *shallow*. They have all
those stories about our past, without even thinking to resolve the
"carnassial" problem. You cannot eat meat without carnassials, or
without fire. Full stop.

Not so sharp. Conchoidal fracture of flint is much sharper than broken clam.

Stabbing to kill prey. Replace fangs with spear allows further distance from prey's defensive weapons.

A sharp obsidian flake slices thinly through flesh & sinew.

Thin-sliced & ground-up meat, chewing gum style.

Cold-blooded oysters, crab, shrimp were not cooked, because their flesh was never hot.
Warm blooded rabbits, antelope, pigs were cooked to bring the meat back to life-like temperature, cold meat did not taste as good. Those who cooked thin sliced meat reduced food-borne parasites so their progeny were healthier.

Nobody ate big chunks of meat, cooked or uncooked, not edible. Mammoth was thin-sliced.

Just the other way around, every shellfish, broken on any way, is very
sharp. On the other hand, from my experience, the flint that yo can find
in nature isn't very sharp. I wouldn't say that you encounter a lot of
conchoidally fractured flint in nature. And even if there is one around,
why would you have it in your hand? On the other hand, if you are eating
shellfish, you handle sharp broken shellfish all the time, and they are
in your hands.
Your objection is very nice example of how somebody can be biased in
his interpretation of nature. You completely ignored the obvious, and
you extremely emphasized some sideway thing.

Who cares. We do have Oldowan stone tools for 2.5 my. We used it for
dealing with wood, hides, we weren't vegetarians.

Hm, why would we stab the prey if we cannot eat it, for god's sake?

No way that I would eat this flesh. Are you crazy? Ok, if this
obsidian is made industrially, and I have a guarantee that everything is
alright with it, it is grounded smoothly. Obsidian used by our ancestors
isn't anything like that.

We ate shellfish raw. We burned surroundings for safety, not for food.
But, this burning gave us food. So, this is how we acquired eating
burned food.

But, for god's sake, why would I compare natural shells to metal
knives? Yes, today we are using metal knives and not natural shells,
this isn't a question. The question we are trying to answer in this news
group is, how all this *started*. Why we *started* to knap stones in the
first place? We just saw stones around, and decided, why wouldn't we
knap them, just for fun?

Brittle, it means that it shutters easily. I wouldn't eat meat with

Stones as hammers against stone anvils sometimes shatter producing sharp edges. The nut meat is still edible.
If the alternative was cracking nuts with teeth, risking broken jaw or teeth, hammering is more efficient.

I believe people have problems grasping this. Not every stone is the
same. Some stones easily shutter, some don't. Flint easily shutters. I
believe that basalt stones don't. You can crack nuts with those that
don't, but those don't produce sharp edges, those that shutter produce
sharp edges. So, you cannot cut meat with a stone. Those that don't
shutter aren't sharp, those that shutter are sharp, but can leave stone
particles in meat.
I am talking about eating meat. Primates don't eat meat, we do. Hence
our diet moved in the direction of meat eating.

What bloody "poor stone"? Every stone that can be sharp is "poor
stone", this goes hand in hand. It is sharp because it is "poor".

Of course I don't, because (ground) metal doesn't shutter. It is you
who doesn't understand anything. By grinding hematite you get ochre. Red
ochre is the evidence that we ground metal. Metal becomes sharp by
grinding, but it doesn't shutter after that. Good morning.

It will (from time to time), it is brittle. It is enough to shatter
once, to brake my tooth.

Exactly. Because if you are used to raw meat taste, you will not like
burned meat better. Only if you are used to burned meat from the very

Have you ever touched obsidian?
You seem very uninformed about it.
Did you confuse it with something else?

[Mario Petrinovic]

No, I never touched obsidian, I really am uninformed about it. I think
that it is a form of glass. This is why it is so sharp.
I am absolutely convinced that it is gravely dangerous to eat meat cut
by Stone Age obsidian tools.

[DD'eDeN aka note/nickname/alas_my_loves]

Be logical. To make an obsidian blade, one must knap it from the side. You can't knap it with meat, it won't chip off, it will cut through.

I don't play Russian roulette. You say, well, there is only 1 chance
