You speak of selection within our species but the time of such
evolution (if there was any) is nothing in comparison with the time of
macroevolution, the one which led, in particular, to the emergence of
our species.

I agree that an organism has a kind of "umwelt", ie, a specific mode

species than Homo sapiens (perhaps Homo neenderthalensis and Home
erectus?) have/had what can be really called an internal
representation of the world.

I was on a tour of the Three Gorges on the Yangtze River a number of
years ago, before the dam was built.  We were on a tributary near
Wushan in small steamers and the river was somewhat crowded with
touring boats filled, like mine, with tourists.  One of the boats
pulled alongside ours and someone in the other boat waved frantically
for us to open the window.  When we did, he leaned out and shouted "Do
you have any Grey Poupon?"

It really was an iconic commercial.

so, having such a concept allows us to make distinctions tha then play
an explanatory role - which is the "added value" you claim is non-
existent

I have no problem with that. It is a different story when you say that
non-human animals have "an internal representation of the world", with
specific and well-defined beliefs.

When a hunter tracks an animal you don't think he has an intend?

If you agree with the concept of "umwelt" you would also agree that
different groups of animals with a CNS have very different modes of
representation of their local environment. One is not truer than the
other one, but each is adapted to the corresponding group of animals
and stems from its evolution history.

Sorry but your answer seems specious to me and doesn't convince me:
when you track something you have an intent.
I maintain that natural selection tracks nothing, it just selects the
surviving organisms, that is all. To explain how such a non
intentional selection combined with the other mechanisms of evolution
led to the extant organisms is, as you know, a very long story of
about 4 billion years. There were numerous steps with many different
mechanisms, constraints, events etc. I agree with you that the final
results are impressive and seem to be teleological. We both agree that
the results are not teleological. Where we disagree is on Griffiths &
Wilkins' interpretation: you consider it is a good one and doesn't
mean that the results are teleological, I consider it is not because
it would mean that the results are indeed teleological. That is the
major point of our debate.

And who said this? The argument is pretty much agnostic to the type of
internal representation that is present in the species under
consideration

Yes, because it is a hunter that does the tracking.  Whether or not a
specific type of tracking is intentional or purely mechanical depends
on the nature of the agent, not the nature of tracking. Your argument
is exactly the same, and just as misguided, as backspaces' who
complaints that "selection" always must imply intend. Sometimes it
does, sometimes it doesn't, a good theory makes clear which type of
selecting is meant Smae with "tracking", the argument as developed in
thae  paper makes it abundantly clear that as the environment is the
agent here, no intend is involved, needed or otherwise in play.

Quite on the contrary as a matter of fact, as my debate with John
showed - where there is intend, we can't assume truth tracking any
longer (I can intentionally breed dogs whose internal representation
of their environment is wrong)

that may or may not be teh case. If you have two species that compete
for food, and one of them has evolved a mechanism to judge distance to
food more accurately ("truer") than its competitor, then ceteruis
paribus the one closer to the actual distance might eventually replace
the less accurate one.

Again, nothing there contradicts the argument in the paper

This argument is specious and dangerous because when it is said that
something tracks something, even if the subject is a thing the ID
proponents will rightly reply that there is an attempting to hide an
intentional intelligence behind this thing.

I agree with you if you say that the environment can play a role, as
many other factors, in the selection of the surviving. It is another
story to say that selection can be a "tracking-truth" process in some
circumstances.

I am sorry but you misread what the concept of "umwelt" means: it is
not an anecdotal skill it is a whole mode of representation of the
local environment by a given group of animals given their perceptual
capacities. Then it is a nonsense to say that the umwelt of a given
group of animals is truer than the umwelt of another group of animals.
Both umwelts are adapted for the use of each group in their respective
environment (as already specified below).

The notion of tracking is not acceptable otherwise you invite the ID
proponents to step into the breach.

It starts:

"In order to navigate successfully through its environment, an animal
must use its brain to keep track of where it is. Recent studies have
shed light on how animals do this: an important clue for how the
animal’s location is represented in the brain has been provided by the
discovery of ‘grid cells’ in the entorhinal cortex of rats. Each of
these cells acts as if the surface of the animal’s local environment
has a triangular grid painted all over it — the grid spacing is two or
three times the length of the animal — and the cell is active whenever
the animal is at a vertex of any of the  triangles, but inactive for
locations in between the vertices"

It concludes:

"The results of these studies point to the entorhinal cortex as part
of a neural map of the spatial environment, and provide insights into
the way that the map is organized."

It has long been known that animals have representations (maps) of
their own body, both sensory and motor, and of the visual field.

You, on the other hand, are not easy to empathize with. I really don't

I fear, subjectively of course, that you are 怨霊 or Onryō, a vengeful

If I had to believe in spirits I would subjectively say you are akin to
Sadako Yamamura in the first Ringu movie and woe be to anyone who falls
victim to your special powers. You could be posting from a well hidden

viral and destroy the world.

Actually there is a misunderstanding. I have no problem with that kind
of paper and expect such data. Of course I knew "that animals have
representations (maps) of their own body, both sensory and motor, and
of the visual field" and thus a representation of their local
environment (I wrote it actually in my posts) as, according of
evolution, there cannot be a deep gap between Homo sapiens and the
other animals.
What I have understood was at stake was a representation of the world
with specific and well-defined beliefs: this seems to me much more
than a representation of the local environment. Don't you think that
to have such beliefs an animal should not have acquired a
sophisticated language?

Nice summary. However, I (now) think that beliefs are not inherited,
only dispositions to acquire them in certain ways. That constraint is
what gives us our Umwlet; that is, the swignificant cues in our
environment to which we respond, and from which we construct our
commonsense ontology (and scientific ontology).

Quine thought that our "quality spaces" - broadly speaking our
propensities to treat things as similar nd hewnce come up with natural
kinds in a natural fashion - were inherited, but I don't even think
that. My present opinion is that we inherit merely dispositions to
acquire types of content, including propensities to treat some things as
more similar than others.

So models of the world, or beliefs about the world, are not inherited as
such, but constructed from, as it were, a common building set, much like
languages and the disposition to learn languages.
