Sea-level changes are as frequent over
geological time as showers of rain were in
Hawaii in the last century. Numerous cycles
(such as the Milkhanovich {spelling?} or
local ones, like as the North Atlantic heat-
pump) produce warming and cooling effects,
making more or less polar ice. They do not
have to be large to create islands or re-unite
them to the mainland. Movements of rivers,
especially in estuaries, do it all the time.
Similarly, volcanic and tectonic movements
produce islands, although much less often.

Chimps do that now.

Chimps have to put them down since
they sleep in trees, and often climb in
daylight. But if there are no large trees.
they won't climb; and so will keep their
clubs at all times. Bipedalism will be
forced.

They don't "chase". They protect
water-holes and the like. The 'chasers'
(without clubs) most often die of thirst
or starvation.

'Chasing' is not part of it. Chimps hold and
wield clubs now. Doing so regularly is an
obvious step, in the right circumstances.

It is not "convenient for [my] model"; it is
an integral part of it, and an obvious step.

What else would they do? Yet again

They would if all around them used them.

Eh? Where did you get THAT from?
Never read Goodall, I suppose. In any
case, numerous mammals (and other
species) fight in groups.

Yes, I have. Those who don't have clubs,
or are poor at using them (perhaps because
their adaptations to bipedalism are not so
good) die, and die rapidly. You have never
seen more effective 'selective factors'
outlined.

Nope. Tool and weapon use was fundamental
to bipedalism. Darwin knew that. You (and all
of modern PA) have forgotten it.

Eh? I can only read your words

Because they're PA 'scientists' -- and
do not remember to look at what animals
do the field, nor consider any factors other
than those immediately in front of their eyes.

'Diet' (in this sense) consists of ALL that
is put into the mouth. If eating roots
means taking in sand and small pebbles
then THEY are also part of the diet.

Bad scientists often make bad assumptions
(and forget all about sand and gravel).
Only a dope like you would think that
there is a good reason to follow them.

Typical standard PA. Zero ability to look

It the sand and gravel that come with them
that destroy soft teeth.

> Grains, nuts, and dried fruit is hard.

Primates can't digest uncooked grain.
Nut kernels are not hard -- stones can
be used to break open hard shells.
Dried fruit is unknown (or virtually
unknown) in nature.

You just don't have a 'hard diet'.
Surely you can see that?

Ridiculous. Firstly humans don't occupy
forest (or do so only marginally). Secondly,
there is nothing in your scenario that
allows you to rule out similar occurrences
in other species.

Faith always has a much firmer grip on

Goodall (the first and best known authority)
did not study 'savanna chimps' -- although
those at Gombe do have a dry season. But
'jungle chimps' (which don't experience a dry
season) are just as aggressive and war-like.
Secondly, what they display is FAR from
"a minimal degree of war behavior". It is
usually intense war.

Of course, they do. You state: "communally
cooperative war based behavior" -- which, for
no good reason emerges from nothing -- in
species sleeping in trees.

Nonsense. I set out the exact physical
conditions that sparked the change, and
then kept it going, in a population of
'chimps'. It probably happened a few
thousand times, before it was successful.

Eh? Small groups among chimps are a function
of chimp mating systems, and the necessity to
finding fresh sleeping-trees every night. Your
model has to continue that indefinitely. There is
no reason why it should change. Whereas mine
has a radical change at the start: they begin to
sleep on the ground. That is possible because
there are no predators. But they leave themselves
open to attack by other groups. At the same time
they eliminate baboons and can achieve a much
higher density, but now larger groups are essential
to ward off attack. They are now possible, since
the shift to the ground brought about monogamy.
Without good protection, females become highly
vulnerable at night -- to rape by stranger males,
etc., etc.

Your model does not begin to compete with
mine. Tell me where, how and why monogamy
came in.

Not so. Numerous species behave in much
more sophisticated ways. Ever study ants?
True, the behaviours would have been
difficult to acquire and it took time -- it is still
taking time. Those that were better at it, did
very well, and those that weren't, died out.

Not so. Intelligent behaviour is always avoidable
and never inevitable. All we are required to do
is set out how it became possible.

The 'forcing' was only at the level that those
that did not follow the example of the best,
died out. Those that kept looking for a
sleeping-tree every night did not do well.
Those that neglected to hold on to their
clubs at all times did not survive -- and
so on and on.

Except that you can't defend it.

What animals are eating that food now?

How come that a highly successful
species eating that (forest) food, just
got up and abandoned that niche?

The change was truly dramatic. Yet you
can suggest nothing. Your early hominids
continued to eat 'chimp food', yet you say
that they now put in a few harder things that,
for some unknown reason, chimps do not
deign to eat at present. Your thinking is
pathetic. It is desperately contrived crap --
and absolutely typical of standard PA.

IF you had anything going for your model,
chimps in areas with dry seasons should have
harder teeth than those elsewhere. But they
don't.

More nonsense. I've incorporated (essentially
static) fighting over water-holes from the start.
These newly-bipedal guys with clubs were not
the best at moving around. I've also had -- from
the start -- them digging for roots (with digging
sticks) therefore directly competing with
baboons, and driving them out of their territory.
Roots are what baboons survive on during the
dry season. Early hominids would have imitated
them. Dry seasons are universal in East Africa.

Maybe you did not read my earlier stuff properly.
However, I am certainly steadily expanding my
theory, incorporating new facts and ideas.
That is what always happens to those that are
soundly based on reality. A niche is always
more complicated that it seems at first sight.
All aspects of the species behaviour must be
inter-related, and must integrate with its diet,
with every aspect of its anatomy, with its patterns
of sleeping behaviour, its social structure, its
tools and weapons, its child-rearing, its method
of dealing with predators, and so on and on.

Bad theories, like yours, constantly run into
dead ends, where there is no possibility of
further explanation for numerous and crucial
aspects of the species anatomy and
behaviour.

Next time, I'll list all those I explain, and set
them against your (non-)list,


Paul.
