plutonium.archimedes@gmail.com - 12 Nov 2008 04:53 GMT
Saw NOVA tonight on the Homo Florensis or Hobbit man found in the
1990s on a island near
Indonesia.

The question was whether Hobbit man was a different species from Homo
sapiens, and it came
to Matt Tocheri to outline the difference between the wrist Trapezoid
bone of Homo sapiens
compared to Hobbit man or Australopithecus -- Lucy.

In Homo sapiens the Trapezoid is boot shaped. In apes and all other
Homo species the
trapezoid is triangular pyramid shaped not boot shaped.

The boot shape is the evolutionary change of going from tree living to
that of Stonethrowing in
order for the wrist to pass throwing motion.

We have the trapezoid bone fossil of Lucy and of Hobbit, but we do not
have a trapezoid bone
of Homo erectus.

Do we have the trapezoid of Orrorin?

I suspect we have the trapezoid of Neanderthal.

Now what this key bone does is layout a complete time line of where a
humanlike fossil fits.
If the trapezoid is tending towards the boot-shape it is ancestral to
humanity. If the trapezoid
is far more that of pyramid shaped means it is far removed from the
direct line of humanity.

So if we analyze the Homo Neanderthal trapezoid we should see it is
far different and more primitive
than contemporaries of Neanderthal which means he was not good at
throwing and would become
extinct over his inefficient throwing.

Now a chimpanzee does throw underarm rocks and stones and the chimp
trapezoid is pyramidal
and so we can grade the differences between pyramid shape to that of
boot shape.

And a part of the Stonethrowing theory is that the progression of
trapezoid changes came far earlier than the
bones that yield bipedalism. So Orrorin was found to be bipedal from
its femur groove, and if
Orrorin's trapezoid is found, it should be far more advanced to the
boot shape away from the
pyramid shape of a chimpanzee.

The trouble I am going to have is that the trapezoid bone to prove
Throwing of a species is rarely
preserved as a fossil. Humanlike fossils are rare to begin with, let
alone the most rare bones such
as the trapezoid.

To prove bipedalism we need a femur bone fossilized and it is far more
likely to preserve a femur
bone than any bone of the wrist.

So the way I see it, is that some 8 to 10 to perhaps 12 million years
ago there existed a apelike
creature living around Southern Italy of say Sardinia who began
picking up rocks and stones and
throwing them to his advantage in gaining more food, more females to
mate and other advantages.
He thus passed down his genes more than others which gave rise to
newer generations of
Stonethrowers. Some 2 to 4 million years later, this Stonethrowing
apelike creature evolved
to have the legs become bipedal to enhance the Throwing. The throwing
caused the bipedalism.

So if we had trapezoid bones of every creature that was apelike and
humanlike from 12 million
years ago, we would see that the earlier trapezoids were strictly
pyramid in shape for motion that
was suited for up and down tree living. But then we begin to see a
trapezoid bone starting to become
well, Trapezoid in shape-- boot shaped, rather than pyramid shape. The
boot shape enhances
Throwing motion, not up and down tree living. So if we had the
trapezoid bone of every creature
of apelike and humanlike for the past 12 million years we would see
this drift in structure of the
trapezoid bone going from the elongated pyramid shape to that of the
more compact trapezoid-
boot shape.

The recent Hobbit man of Indonesia and the Neanderthal man had
trapezoids that were more aligned
with the pyramid shape rather than the boot shape of modern man.

But it is rare to find a Trapezoid bone preserved in fossils. So what
I am going to propose is that
the motion for throwing is also indicated by other arm and hand and
wrist bones. There is probably
a signature in the most often fossilized bone of the arm.

The femur is probably the most fossilized leg bones, so I am
suggesting that there is a signature
in the arm bone as well.

In the NOVA tv program of Homo floriensis (hobbit man) with Matt
Tocheri discussing the uniqueness
of the Trapezoid wrist bone and saying that it allows motion
transverse to the up and down motion
for tree living, well, I would conjecture or speculate that there is
some uniqueness in the large
arm bones and shoulder bones for motion that is not tree climbing but
rather for motion that
involves Throwing.

So I would conjecture that there is some unique feature of Homo
sapiens radius, Homo sapiens
ulna, Homo sapiens humerus, Homo sapiens shoulder bones that confers
throwing motion rather
than tree living or tree climbing motion. I am concerned that these
larger bones have some signature
for throwing because most bones found of ancient humanlike or apelike
fossils will rarely be the
trapezoid bone but rather these larger arm bones. So in the entire
fossil record of humanlike or
apelike bones we may have only two or three trapezoid bones in total,
whereas we may have
thousands of other arm bone fossils. So I want some unique feature of
bones that indicates
the individual was a thrower. I wish the teeth could tell whether the
owner made his living by
throwing since the teeth are the fossils that survived the most. And
perhaps that may be true
in that the more throwing, the more carnivorous.

Yes, of course: Frans de Waal, evol-psych 22.9.01: In all research
facilities with chimpanzees it is known how well apes throw. This is why
projectiles are kept away from them, and why they mostly work with feces.
They are deadly accurate, they swing around from the back of their cage and
invariably "nail" the one new face in the crowd with deadly accuracy. Ask
any worker in such a facility: it's not rare, and no illusion!
Out in the open, their skills are even more striking. I used to photograph
the Arnhem chimpanzees from across the moat, where they were at about 10 m
from me. I had to be extremely careful because young males tended to throw
extremely well. They would see my eye go behind the camera, and all of a
sudden it turned out they had a stone with them which they'd throw at me.
Males more than females, mostly overhand. (Another tidbit in the debate
whether they know if our eyes are for seeing or not Š).    Then there was
the mother who came to the reception with her crying son. She complained
that our chimps threw stones. After questioning and an account by a
bystander it turned out that the boy had thrown first, and that the same
stone had come back to him. The estimated distance of this case was 25 m.
In short, the idea that apes can't throw is bogus. It has been around for a
long time, but should be tested with apes who have had target practice. I
invite all man-the-thrower advocates for a visit - at least if they don't
mind some smelly stuff coming their way!

Compared to a starfish, chimps throw well. Compared to Homo, they
throw lousy.
Ever see a chimp throw a 90 mph curveball? Ever see a chimp knock down
a zebra
with a rock at 30 yards?

Better read William Calvin and Barbara Isaac on throwing before you
make anymore
stupid comments.

Given years of practice and coaching one person in a million can do
that, so the comparison is fatuous. Comparing an average untrained
human with a chimp, from Marc's anecdotes the chimp seems to have the
leg up.

It doesn't discuss chimps. I also didn't find anything about skeletal
anatomy. Isn't the article just speculation about neural development?

No, it simply means there are 6 billion couch potatoes on the planet
now and few hunter/gathers. Any human who is
not an invalid can be taught to out throw a chimp. This is why the
other apes also do so pooly at flintknapping, which is clearly linked
to the ability to throw, see Toth.

No, it means chimps can't throw worth a sh.t and stupid anecdotes is
all that wetloon ever had.

That's because they don't throw well enough to be included in his
scheme of brain evolution.
According to him, if chimps threw as well as we, they would have
evolved large brains also.

The physical barriers for why a knuckle-walker can't throw a knuckle
ball can be found in just about any of Toth's books.
You will need to read a few Toth and Calvin's  books to get the
complete picture.

You're argument didn't fly, so you substitute a naked claim. Moreover
"out-throw" is an attempt to move the goalposts. The original point
was that the human unique wrist bone confers the unique ability to
throw. That's contradicted if chimps can throw competently, even if
not quite as well as humans.

I see. I guess the fact that Ira Smith's "Baseball's Famous Pitchers"
also doesn't mention chimps is further evidence that chimps don't
throw well.

That's not in the article explicitly; it's your inference from the
speculation in the article about the "Law of large numbers"
relationship between neuron patterns and throwing, right?

Leaving aside the question as to whether the speculation is informed,
the chain of reasoning you're introducing seems tortured.

1. The OP reported the idea that throwing ability depends on our
unique wrist bone.

2. Marc Verhaegen replied that's contradicted by the fact that chimps
can also throw. (Granted I have your personal assurance that he's a
"wetloon" as a nearly-persuasive reason that he's not to be trusted.)

3. Your argument is that the reports that chimps can throw must be
wrong, because some article or other argues that throwing accurately
theoretically requires a bigger brain than chimps have.

That's tortured because it claims a speculative theory trumps
observation. It's also irrelevant to the argument that the wrist bone
is essential for throwing.

I read the article you cited in the first place and after gagging on
the authors' bizarre invocation of the Law of Large Numbers I'm not
going to give them, or you, a second chance.

Fine.

No, chimps do not throw competently or anywhere near as well as
humans, you understand as little
about chimps and throwing as you do about wrist bones that prove
chimps do not throw well at all (see below).

Yep, a 10 m throw, no matter how accurate, just won't get you in the
record books.

OK, so YOU can't throw.

You said it best, "Marc's anecdotes" says it all. To the best of my
knowledge, no formal
published study has been done on chimps throwing. We only have what
informal observations that have
been made by others.

What Frans de Waal observed, with chimp slinging accuracy, had little
or nothing to do with  wrist
action, so much for Marc's anecdotes.

No,  "observation" confirms the fact that chimps  use a locked wrist
while slinging
sh.t falsifies any claim that the wrist has anything  at all to do
with their alleged
throwing abilities, no matter how you rate them, good or bad,
confirming Marc's wetloon status.

For chimps, yes, for Homo, no. If my argument is tortured, your
comments are blind.

Well thank you, one less loon I have to explain everything twice to.

A locked wrist (or no wrist bones at all, for that matter) does not
hamper accuracy, it hampers
distance/speed that gets you into the big leagues on the savanna. The
difference is akin to the difference
between how a discus thrower and a baseball pitcher do their throws.
You could put the discus throwers wrist in a cast
and he still wouldn't be hamperd all that much and probably would be
just as accurate. Do the same to a major league pitcher and he
wouldn't make the team.

Pretty simple, just a little "observation" needed, just think of the
chimp as an accurate discus thrower, not a pitcher.

You have a nice day, Charles.

(side note:  This Charles is not the same guy as me... I post as Chap
now, but was Charles..my real name...in posts a few years ago.)

Lee, I read the paper, and much of Calvin's website.  It "feels" like
he has backed away a little bit from the earlier (1980) brain work
connecting throwing and language.  I thoroughly enjoyed his ape
pictures and the flavor of his lectures.  He is a great contributor to
the discussion & research.

Brain research has changed a lot since 1980.  We are less dependent on
brain injury speculations.

Much of the math in the paper is obscure, or seems pointless.  A frog
uses the same "math" to catch a fly.  However, any time that we can
quantify an action and repeat it, yippee.

I am not convinced that the references (in the paper) to how children
throw is quantifiable.  Children rarely throw overhand until they have
been in an organized sport.  Or, stated differently, this could be the
subject of an actual research project.... Children's preferences in
throwing an object.  I see a side throw most frequently, or
underhanded.  Really, dumping, pushing and playing in sand and water
are prefered over throwing a ball.

The paper suggests that being stationary may be a preferable hunting
strategy over running.  "Strum (1981) reports that individual baboons
prey upon birds and rabbits, catching some with a short chase but
merely seizing most as they lie motionless in the brush; Thomson's
gazelles require stalking and chasing."  Most sites that have thus far
been excavated show an abundance of small game remains.  My point here
is, which is it?  Running down prey until they drop from exhaustion,
or sitting still and beaning them with a rock?  Are these two mutually
exclusive?

I have not seen any research that compares chimp throwing ability &
development of their Broca's area & right brain versus human. Is there
such a paper?

:-)  Finally a bit of common sense.

Some comparative data:
1) Even a praying mantis (tiny brains) throws itself upon its prey.
2) Sealions have an excellent sense of equilibrium & can throw balls into
nets with their noses.
3) De Waal doesn't knows much on human evolution, but he knows a lot on
chimps & he says that chimps are excellent throwers.

Well, when they start to leave handaxes around the savanna I will be

Wrong, you said, he said, accuate for short distances (10 m) and that
doesn't get you into the record books, they are losers. Their short
distance (accurate) throwing is with a locked-knuckle-walking
wrist that doesn't require human wrist action at all. That is just one
of the reasons they can't flintknap well either.
There can be no meaningful comparison between how chimps and humans
throw, like sealions, it ain't the same thing.

Fine, but my point was clearly stated from the start,
Lee said: “Better read William Calvin and Barbara Isaac on throwing
before you
make anymore stupid comments.” Key words: ON THROWING.
I was referring to his work in general, I certainly don’t agree with
all his statements or ideas.

Bingo, I agree 100%. Now, add up the work of Toth, Calvin, Wynn,
Whittaker, and throw in O’brian’s famous handaxe-throwing paper,
re-tested by Calvin, Whittaker, and Lee Olsen and things start to
jell.

Kids also can’t make a handaxe until they are about 7 years old, or
so.
Modern humans can’t visualize in three dimensions, nor do they have
the
wrist power needed to break the rock at young ages. They don’t run
very well early
either, not like a kudu baby.

Overhand or underhand preference really makes no difference. Have you
ever tried
to catch a fast-pitch soft ball thrown by a professional? All I can
say is duck. It’s all
in the wrist. Nor can the average couch potato detach a flake from a
basalt rock with
a hammer stone without a lot of practice (if at all), it’s all in the
wrist, that is the critical
advantage. Kids and chimps simply can’t do it.

Most of this basic stuff can be found in:

Both methods work, and everything in-between. The book Emergence of
Man,
Leakey’s books, Barbara Isaac’s paper are loaded with examples of how
humans
catch and kill animals (much faster initially) without guns or
spears. Hadza women
and children run down sub-adult kudus and beat them to death with
their digging
sticks. Whatever works, do it, that’s what our big brains, legs, and
wrists are for.

Lee, it's pretty obvious what rhetorical tactic you are employing
here.  Twice now you've insulted us by asserting that we have not read
something.  One can only wonder why it is you would have us reread
what most of us have read 5 or 6 times by now?  If there is some
specific point in this general reference why don't you just tell us
what it is?  Provide a direct quote.

Please don't keep it secret from us anymore, Lee.  Tell us of this
special understanding that you've been withholding from us.  I can't
take the suspense any longer.

Things start to "jell"?  Really?  I guess we'll just have to take your
word on it that. I must have missed something the other 7 or 8 times I
read it.  Maybe someday Lee will tell us his secret.  Maybe it
involves some kind of special decoder ring that he got in a box of
cereal!

Lee, thank you for these general references.  I'm sure they will be
helpful to somebody.  But beyond that it doesn't seem you have much of
a point here.  Your whole "point" here seems to be summed up perfectly
in your own words, "...my point was clearly stated from the start,
'Better read William Calvin and Barbara Isaac on throwing before you
make anymore stupid comments.”'

Lee, FYI, you can safely assume that every participant in this NG has
read this paper multiple times.  In fact, Lee, you can safely assume
that every participant in this NG has read this paper and all of its
referenced material multiple times.  Beyond this, Lee, its more and
more starting to seem that you have no specific points you'd like to
discuss.

I think this just makes sense.  And I'm not saying that just because
it is consistent with (and even complimentarty to) the communal
territorialism of my hypothesis.

Ya know, Lee.  For somebody who is constantly harping on Marc
Verhaegen (rightly so, IMO) for introducing anecdotal evidence, it's
surprising how plainly anecdotal is the evidence that underlies your
own, somewhat vague, assertions.  Here he is slyly trying to suggest
that the fact that Hazda women run-down and beat to death Kudus that
this reflects the behaviors at the transition between ape and the
earliest hominids.  (Of course Lee will, now, deny that he ever
implied such.)

I don't disagree.  However, if it becomes just another generalist
strategy (ie, either running or sitting or both), then it loses
explanatory value.  IMHO, some one or two factors must be sussed out
to explain the evolution in our line of 1.  bipedalism circa 6mya,  2.
encephalization circa 2.5 mya, and 3. fully developed language and art
circa 200 kya.  We are generalists NOW, but which factors brought that
to us?

Throwing in humans needs to be further differentiated from the chimps
in order for it to qualify as a selection factor, in my opinion.

It's pretty obvious you haven't been to a library in your life.
1. Nobody lived on the savanna until the advent of jeeps and guns.

Well, okay.Marc does kinda have a point here.  Apes have been on this
planet much longer than hominids.  If human evolution was *simply* the
result of stone throwing behavior in and of itself then we'd expect it
to have begun shortly after the appearance of the first apes.  Since
this observation is plainly inconsistent with what is observed in the
fossil record this 'proves' that human evolution could not be the
result of stone throwing behavior in and of itself.

This does not, however, rule out stone throwing behavior altogether.
It just shows that there has to be more to it than *just* stone
throwing.

Yep, 10 m, about the limit of their poor throwing capacity, much
beyond that they are completely helpless.
That is one reason they never weaned themselves from the trees. With
this limited capacity to throw well,
they could never scare a lion off a kill on the savanna, as Homo can
easily do. With our ability run, sweat, and throw,
Homo is perfectly adapted to life on the savanna. This is why tools
and Homo fossils are found on the savanna
and chimp bones are not. When a rain of boulders hits a lion in the
head from 50 m away, thrown by Homo, he knows its time to hide.

Chimp predation problems arise at night.

No primate (or other animal) can throw
well in the dark.  You need to be able
to see what you are throwing at.

Neither Homo nor chimp can scare a lion in
the dark.  Lions can see in the dark,
primates can't.

Homo has, in effect, a ZERO capacity
to run. Every mammalian species on
the savanna can far out-pace Homo.
Sweating is pointless on the savanna,
(which is why no savanna species does
it).  The necessary replacement water
and replacement salts are far too hard
to obtain.

Homo died on the savanna, often leaving

plutonium.archimedes@gmail.com - 14 Nov 2008 08:25 GMT
Now in the NOVA tv show of Homo florensis or Hobbit man found near
Indonesia where Matt Tocheri
shows that the Trapezoid bone clearly shows Hobbit as a different
species, yet where chimpanzees
and Hobbit and Neanderthal threw rocks and stones, needs
clarification.

Only Homo sapiens has a boot shaped or trapezoid shaped Trapezoid
bone. One can infer that the
naming of the trapezoid bone in humans was because it was shaped as a
geometrical trapezoid.

But in chimps and Hobbit and Neanderthal their trapezoid bone was more
pyramid shaped, yet they
still threw rocks and stones.

So, does that damage the Stonethrowing theory? Not at all. We must
realize that it is evolution
at work and gradations are what is at play. We must also consider the
definition of throwing.

A chimpanzee only throws underarm, never overarm like a baseball
pitcher. So a chimpazee is
purely a underarm and never overarm and never able to lift a boulder
size rock and overarm pommel
and the chimpanzee trapezoid bone is the most pyramid shaped over all
hominid bones.

If we were lucky to find a Orrorin trapezoid bone, it would be
slightly more boot-shaped than
pyramid shaped as the chimpanzee and thus allowing Orrorin to throw
overarm, although crudely
overarm.

The pyramid shaped trapezoid bone of Neanderthal and Hobbit was far
more converging on the boot
shape of Homo sapiens than it was on Orrorin. And so the Neanderthal
and Hobbit were able to
throw overarm but not as efficient as Homo sapiens.

So the gradation of pyramid shaped trapezoid to boot shaped trapezoid
from Orrorin to Homo sapiens
was a gradual evolving from pyramid to eventually the full boot shaped
Homo sapiens.

Now here is a nice easy experiment and I wish I had a chimp to test it
out on. Hold the arm
motionless. And only the wrist and hand can be in motion. Have it on a
table near an object
like a pen. Now the hand can pick up the pen and set it backwards in
preparation for a thrust
forward, and a thrust at various angles. So, in other words, with only
the wrist and hand allowed
in motion, can a human pick up a object and throw it. Now I just did
this experiment and threw
a pen about a meter in distance across the table. Now I suspect that a
chimpanzee is incapable
of doing that experiment because of the shape of those wrist bones
starting with the Trapezoid.

And looking at a picture of all those wrist bones near the trapezoid,
they all appear to have
been modified by evolution from a up and down motion consistent with
tree climbing to that
of boot shaped bones to have lateral motion for throwing instead of
climbing.

Now I do not own a chimpanzee to be able to test him/her out on
whether he can fulfill that
experiment, but I do know that chimps throw only underarm, and so
going with that information
leads me to suspect that a chimp could never fulfill the above test.

So not only is the trapezoid bone of Homo sapiens unique to Homo
sapiens for Throwing but that
all the wrist bones have been evolutionary modified from Orrorin to us
to increase throwing.

P.S. But I would like to find modifications on the radius, ulna,
humerus for throwing since those
are the bones most often found fossilized.

"The Schoningen spears now provide unambiguous evidence that large
animals
were killed in this manner by 400,000 years ago.
"The spears have other exciting implications. First, the time and
skill
needed to make them: each is made from the trunk of a 30-year-old
spruce tree;
in each, the end with the tip come from the base of the trunk, where
the wood
is hardest; and each has the same proportions, with the center of
gravity a
third of the way from the sharp end, as in a modern javelin. These
represent
considerable investment of time and skill--in selecting an appropriate
tree,
in roughing out the design and in the final stages of shaping. In
other
words, these hominids were not living within a spontaneous 'five-
minute
culture', acting opportunistically in response to immediate
situations.
Rather, we see considerable depth of planning, sophistication of
design, and
patience in carving the wood, all of which have been attributed only
to modern
humans." ~Robin Dennell, "The World's Oldest Spears," Nature 385(Feb.

http://tinyurl.com/622l75
Nothing wrong with a Neandertals idea of symmetry. Some flint handaxes
are given a final shape by
small secondary-retouch flakes. This is also an indication  nothing
was the matter with their grip.

Since they went to so much trouble with symmetry and to make what
appear to be throwing spears ,
my bet is they could throw pretty well.

If we go further back to the beginning of the Acheulean and early Homo
e, some of their handaxes
were made from basalt that is very difficult to knap, even a good
knapper like Toth ( I think was
a former athelete) has trouble with this material. You have to
literally throw a core upwards with
one hand and swing a hammerstone downward into the core and also
impart a snapping of the wrist
during contact in order to detach a flake.

I have a man-made quartzite chopper. It has 4 flakes detached from one
end only, the other
end is a unmodified rounded cobble. I tried to knock a flake off the
bottom, unmodified end, and
I couldn't do it. Someone in the stone age was a lot stronger and
better coordinated than I am.

From this I infer Homo e was a pretty good thrower also, since it has
been pointed out by Calvin
and Toth how similar throwing is to flintknappeng tough materials.

Nature 422, 395 (27 March 2003) | doi:10.1038/422395a

Despite their ability to make and use stone tools, Neanderthals were
presumed to have had limited manual dexterity on the basis of the
anatomy of their thumb and forefinger1 — a contention that has been
called into question2, 3, 4. Here we investigate the likely extent of
Neanderthal thumb function by using a three-dimensional dynamic
simulation that is based on the anatomical details and articular
morphology of the thumb and index finger. We find that these digits
could make tip-to-tip contact, and conclude that manual dexterity in
Neanderthals was probably not significantly different from that of
modern humans.
--- end quoting Nature ---

So far I have the notion that a Neanderthal trapezoid bone was
recovered.

But what I do not have as yet is the understanding as to whether the
trapezoid of a Neanderthal
is fully the same or interchangeable with the trapezoid of a Homo
sapiens?

Is there any noticeable difference between the Neanderthal trapezoid
and Homo sapiens?

My guess is that there is a large enough difference such that no
Neanderthal team of
dodge ball could beat a Homo sapiens team.

My picture is that evolution designed a throwing species and there
would
be many models of throwing for many species of throwers, but in the
end
only one species would be alive and extinct the others. Like one huge
and long 10 million years of a dodge-ball contest and the loser goes
extinct.

I guess the skull with the browridges is the most often found fossil.
The
recession of the browridge would parallel the need for increasing
peripheral-vision for throwing. So Neanderthal with his large
browridge
was no match for Homo sapiens.

I would think knapping activity could go on for days months and years
without
ever a problem in the arms or hands. But only a few hours of strenous
throwing
gives me problems with the muscles and joints and ligaments in the
elbow
and shoulder region. Throwing to save your life, I imagine would do
alot of
stress on the elbows. I marvel at baseball pitchers how long and fast

P.S. have you got a full Nature article above? And do they say whether
the trapezoid
of Neanderthal -- whether they are starkly different than in Homo
sapiens?

This jewelry  was found with a Châtelperronian lithic industry  and a
34,000-year-old Neandertal temporal bone.

You do not make tiny grooves and holes in teeth if you don’t have tiny
threads and the ability to make tiny knots to hook them together. In
fact, just
having the equipment to drill the holes in the first place proves
manual
dexterity as good or better than mine.

The error that is frequently made in the literature is in comparing
dissimilar aged bones
because that is all they have.  The evidence at Arcy-sur-Cure proves
that Neandertals
were evolving morphologically and culturally  as fast as  Hss.

If you compare both at only 33,000 BP who knows, they simply don't
have
enough fossils to compare.

Could be, but what would it mean if a team of Watusi could beat a team
of
pygmies at basketball?

Then could the same argument be applied to the Dorset and the

What about the Saint-Césaire skeleton with small browridges or

I get the same injury to the wrist knapping for long periods as I do
playing
too much tennis.

Yes, but when I was a kid, if a pitcher was having a good day, they
left him in for
nine innings. Now they normally pull them after so many pitches, good
game or not.
They still give them 4 days rest, with few exceptions.

Unfortunately there is a huge gap in fossils from 40 kya to 27 kya for
both Neandertals and Hss.
I think the inferences will have to be made from the incised teeth at
Arcy.

Are you familiar with the atlatl, which was probably invented just
after the Neandertals
went extinct? That is another toy that uses a lot of wrist motion.

Thanks those two websites were helpful. The first website I presume
shows a Neanderthal
skeleton and the trapezoid bone looks to me as though it is more
pyramid shaped than
trapezoid shaped (boot shape of modern man).

The second site states this:
"Early and Late Upper Paleolithic hand remains are more similar to
recent human hands
than to Neanderthal hands"

"adapted for power during manipulation"

Just as the Hobbit man of Homo floriensis found off an island of
Indonesia recently tells us
the trapezoid bone makes the Hobbit a different species, we can look
at the trapezoid of
Neanderthal and it also tells us Neanderthal was a different species
purely from the
differences of the trapezoid bone.

So the picture we would have of the evolution was that when
Neanderthal came in contact
with ancient Homo sapiens they were extincted via the stonethrowing.
Sort of an awful way
to become extinct; to be pommelled to death by stones.

So Anthropology as a science is very much completed and closed with
only details now to
fill in the blanks.

Anthropology starts at about 12 or 10 million years ago and we can
take any samples of ancient
apes of 10 to 12 million years ago. Take our best ancient ape sample
and now we take a skeleton
of modern human bones. Now we simply say, what bone changes did
evolution have to make in
order for the skeleton of ancient 12 million year ago ape to become
the modern day human skeleton.
The trapezoid of ancient ape was pyramid shaped and the trapezoid of
modern man is boot shaped.
So in 12 million years time evolution had to change the trapezoid bone
and in that time had to
make the elbow and knee and pelvis the midpoints of arm, leg and body
respectively. And in that
12 million years had to make the arm 70% length of leg. There is only
one behaviour that can fullfill
those 12 million years of evolutionary change -- Stonethrowing or
Rockthrowing.

Every other fossil bones found in that 12 million year span are added
details or facts proving the Stonethrowing
theory.

“Conclusion: The most interesting thing about the Levantine record is
that until 47,000 BP, there is no objective basis for predicting
whether Neanderthals or early modern humans would ultimately be the
most successful, and certainly no way to predict that modern humans
would permanently replace the Neanderthals. Because we know the
Neanderthal fossil record so well, relative to other hominid fossils,
and because we know they became extinct, there is a tendency to see
Neanderthals as inevitable evolutionary “losers.” However, studies of
their fossils and their archaeological record point to no obvious
defects in their adaptations. Neanderthals and their Homo
heidelbergensis ancestors evolved and thrived between 300,000-30,000
years ago, nearly a quarter of a million years, in some of the
harshest and least hospitable habitats ever occupied by hominids. The
picture of the Neanderthals emerging from recent research is one of
formidable competitors, humans every bit as worthy of our interest and
admiration as our own direct ancestors.”
