Really? No. This is much too vague. There's a lot of
animals that can be described as: " . . . protecting their fruit &
vegetable resources." The actual behaviors I indicated in my
hypothesis were more specific and explicit than you are indicating
here. It might be a good idea to read that part again.

What you are saying is correct. But it is lacking in a
lot of the specific details that are absolutely necessary
to understanding peculiarity of the selective factors
described in this hypothesis.

Climate changes rapidly. It shifts.

I haven't been able to find my reference for the 8.1 mya figure.

So, all I have is the following, which you may have already seen.

http://www.cix.co.uk/~awhitec/HumanOrigins/Climate.htm

This geological event created a monsoon that released vast quantities
of rain, drying out the air that flowed through it. This same air flows
across East Africa, and caused rainfall to drop sharply, drying the
rain-forests and replacing them with broken scrub and woodland. It is
no coincidence that the monsoon intensified 6-8 million years ago -
the time at which the common ancestor lived.

Yes. (I highly suggest reading the taphonomy and environmental

same in my hypothesis.)

No.

I think this is because, as I mentioned above, you have not yet
correctly conceptualized the behavior in my hypothesis. There's much,
much more to it than can be accurately captured by the phrase: " . . .
they remained fit by protecting their fruit & vegetable resources."

I make no claim to exclusivity of territoriality. I do make
claim to the type of territoriality indicated explicitly therein.

That there are other primates that throw things is not a challenge at
all to my hypothesis. In fact if they didn't then my hypothesis would
be lacking some very important preadaptive behavior. The difference is
that selective factors, as I delineated. And, as I hope you realize,
the peculiarity of these selective factors is completely dependent on
the dry season and it predatory implications with respect to the, all
important, level of poverty in the community. Do you see this? (It's
very important that you answer this question honestly.) If you don't
then you have missed the whole point of the hypothesis.

I think the best evidence is that it happened 6 to 10 mya. It really
makes little or no difference to my hypothesis as to exactly what that
date is, IMO.

It seems to me that it is, also. Maybe I'm missing your point

Kinda. Communal selection refers to the fact that when the adaptive
behavior of this hypothesis failed (resulting in the impoverishment of
the whole community) this could doom the community as a whole. This,
of course, was a result of the predator siege/massacre behavior that I
theorized to have been present in the behaviors of late miocene
predators.

The community vs. community aspect refers to the fact that, in the
context of these same behaviors/assumptions, the communities of this
scenario are in competition with each other in that the predators will
seek out the community that is relatively most impoverished and tend to
ignore others in the area. This community vs. community aspect
indicates that they had to keep getting better and better at achieving
their resource maintenance goals. IOW, this is represents the origins
of what we might now refer to as economic competition between
cities/states. This provided an autocatalytic selective aspect to this
scenario that rewards communities that are able to get better and
better at the described behavior. This is the engine of human
intelligence, consciousness, culture, etc.

I hope I understand your question. I think you'd agree that tool
making that is evident about 2.5 mya is the result of two things. The
first being an increase in their manipulative abilities. And,
secondly, an increase in their intelligence and consciousness. I hope
you'd agree that the rock throwing, stick-wielding aspects of my
hypothesis describe the origins of the manipulative abilities. I doubt
you'd dispute this. The intelligence and consciousness aspects of it
are a result of the community vs. community selective aspects/pressures
that I discussed above. My thinking is that this would have been a
slow process, taking millions of years. Millions of years of
autocatalytic selective pressure for these communities to become better
and better than each other at achieving their resource management goals
year after year, dry season after dry season.

I'm not sure if things can be categorized as you suggest.

What I see in my scenario is an ape that is being selected for its
ability to be a productive member of a new biological entity, the
hominid community, in that if he/she doesn't the predators will take
out the community as a whole. This entails the selective origins of
all the traits and behaviors that distinguish humans from the other
species. These are extremely unique selective factors unknown in any
other species: intelligence, communicativeness, etc. This was a
species whose survival was tied to the ability of its community to
preserve resources to avoid decimation of the community as a whole.
There is no one behavior predicted by these strange selective factors,
IMO, instead we'd predict a diversity of behaviors. And this gives us
some hint as to the selective origins of human cultural abilties. This
is not just group selection it's a very particular form of group
selection.

It's a tough subject. I think you're catching on, but I'm not sure.
Maybe the following will help with giving you a better understanding of
how to flesh out the backdrop of the scneario I layed out:

Maybe the thing that is most difficult for modern humans to comprehend
about the earliest years of hominid evolution was the ecological
realities. We now live at a time when humans dominate. During the
late miocene large migratory mammals and the predators that preyed on
them dominated the landscape. And because of the annual dry season
there was constant activity. It was a very different place.

If you have any more questions let me know.

Regards,

Jim
