I guess you have to ask <name> [I can't remember his name now
it might have been Planck] why he said something like:

I'll get the exact quote and author when I get to the office.

WEll, since you find it so easy to keep arguing, I can't stop
now :-).. Definitions are already there. Check any dictionary.
The "scientific definitions" sometimes are out of operationalism,
sometimes forced by people who think that they are necessary and
sometimes not even clear.

You have missed the point entirely. IT's exactly because they're
is no agreement that most of the verbal arguments that people
are having are not coming to any conclusions. One group defends
the status quo rather vociferously but there is no clear cut
data/evidence that supports that view, certainly no more than
the AAT. They keep changing things, and then claim that AAT'ers
change things and it disqualifies them but not the SST'ers.
So it's pointless to ask for references. It's meaningless.

Here we are again. What you call "gut feeling" I called
skeleton-eye-balling; and another called bone-gazing. All I
wanted to do was to put the real argument in perspective by
asking people to give numbers. We can then discuss why one says
it should be, say 5, and another 6.

I have great respect for scientists. I hope to be one someday.
(Some probably think I already am one.) But I am great on
deriding pompous and obnoxious asses.

None of them better in any way than the one that's got the
water in it, and most of them worse.

It could reach near zero in the desert. It might even reach zero.
If the "savannah" was "hot and dry" that for sure means that it
would be colder at night than if it was moist. I've been in
dry weather in the middle of the summer in which it was impossible
to stand in sunlight during the day but I had to use a blanket at
night to stay warm. Under these conditions there must have been
a particularly good reason to lose the fur. Now if the humanoids
did not need to lose their fur in the hot and moist forest
then why would they start to lose it in dry savannah?

If you already don't have fur, you can huddle all you want.
The question is the conditions that led to its loss.

Because, once again
1) It would be easier for them to adopt the erect stand since
the water would support them. Chimps don't have their hips directly
underneath them. It's harder for them to stand up erect and their
muscles would tire sooner. It would be hell for them to carry
anything bipedally. This would not happen in water.
2) It would free their arms to carry things around in water and
3) The survival value of long legs has been told already.
4) The soft flat feet seems ideal for sand walking. Check the
5) It would be easier to defend themselves since their arms
would be free and the predators would be at a disadvantage.
The stick swinging would work much better here than in the
6) There's be no reason to have grasping feet and hence
no loss of survival value if the grasping toe disappeared.
I can probably add more..but it all revolves around the
simultaneous positive feedback toward the new anatomy while
the negative feedback is there since the short footed ones
and short ones would die. Since we are not great runners,
the value of long legs on land remains low. Nobody mentions that
they'd need long legs to swing sticks and make noises against
lions. Nobody says they needed long legs to outrun lions.
So why are their legs growing longer on land? And then of course
there's the "significant tree-climbing ability". If the need
for tree climbing was still around, why were they becoming
bipedal on land? To run? No. To swing sticks? No.
> B: Who said there were no trees? Are we back to the treeless,
>waterless savannah strawman that others have tried to bring up?
Fine. Bring the trees. Bring the significant tree-climbing too.
They why the long legs and why bipedalism?

>stand more upright (immediately gaining some mechanical advantage),
OF course it's real. Nobody claims that they beat lions with the
sticks. Who was it who was claiming threatening gestures and
screaming? Was it you? Did you or anyone claim that they made
spears and killed lions? No! Wanna change your mind?

They could not have carried things too far nor would they have
had to if you claim they were in the forest. IF so, then there
should be no chimps etc. Why would they have to walk far? Are
you saying that they ran from one tree to another in the
savannah? And how far did they run to the waterhole? As for
looking over the tall savannah grasses, one of them would have
screamed others would have been warned. Unless of course, you
want to contend that they were smart enough not to scream and
they used stealth. Even then the advantage of being tall is not
that great. They could have stood on top of mounds like the
prairie dogs or they could have climbed trees. After all, in
your savannah, they'd have to hang around trees so they
could scamper up to escape predators.

It might not be the same. But it could be even a higher order
of thinking. After all, what brought about QM ? What kind
of revolutionary thinking led to it? Besides, it's not necessary
to see some animal do things to think that it could be done.
There are two reasons why we use it. One is that analogical
thinking is ingrained in us. It's a kind of a monkey-see,
monkey-do. The other is that it's easier than being creative.
When we see things we can't imagine, we no longer have to try
to imagine it. It's easier. If we don't see it, then our
task is more difficult; we have to imagine it.
Think about languages. If you only speak a single language,
start to think about what other things would you like to
see in English. After that read about some of the strange
and exotic things languages do, and if you are honest you
will see that they do things which you couldn't even imagine
could be done in a language. After seeing some languages, then
you might start to think about what other strange things
languages might have but yet haven't found in any language.
Could those things exist in a real language?
