What example ? The only concrete thing you gave in your post was about
multi-regionalism theory; I agree that this was a specific example of an
extent to which multi-regionalism theory is true.
But that has nothing to do with aquatic ape theory. Care giving an
example of what extent you're thinking about for that one ?
You're an idiot. Seriously.
> Living on the shore line and finding aquatic food does not mean

You're saying that exploiting an environment doesn't lead to
a species evolving to suit that environment.
Should we take into account that the proposed aquatic period would have been
millions of years back in time, and probably not 'very' long?
One problem is that we don't have any(?) information about the environment
during the hypothetised aquatic period. The way I see it, it would have to
be
rather isolated and somewhat unique but not unthinkable.
Although much of the geological history of the Afar(?) region seems to be
known.
I have no clue which one you're talking about. It can't be the one where
you talk about multi-regionalism, because I said already in the post
you're responding to and the one responding to that post that I don't
see the link between multi-regionalism and the aquatic ape hypothesis.
If there is one it would behoove you to explain it instead of throwing
out cryptic statements. And it can't be the post where you give a
general rundown of ALL the extents to which the aquatic ape hypothesis
could be true with only the barest hint of logical inference linking the
more extreme bits to the more trivial bits, because according to my
newsreader you posted that BEFORE the post where you say you gave an
example.
So color me still not understanding what you're talking about.
As is, your formulation is not only minimalistic, it's so vague that the
only response one can have to that is "sure, maybe". A hypothesis needs
to be a bit more precise to be useful.
Yeah. You realize this is only a meaningful statement if "related to" is
a norm that applies to the space containing people A, B, C and D. If the
distance of the relationship between A and B isn't something I can
measure and then apply the same measure to the relationship between C
and D, saying that C and D are as closely related as A and B are is not
very useful.
As it happens, I've never heard of "extent of trueness" being a norm
that applies across theories. What does it mean that multi-regionalism
is true to the extent that Europeans contain a few percentage points of
Neanderthal DNA; is there a number I should be able to calculate from
that statement, that I can apply to aquatic ape theory to figure out
exactly which aspects of the theory could be true there for the "extent"
to be the same ?
Of course not. You just meant that multi-regionalism is something that
turned out to be true to a little extent, and aquatic ape theory could
also turn out to be true to a little extent.
But I asked to WHAT extent you think aquatic ape theory would be true.
"Some extent, like multi-regionalism theory" is not an answer. "The same
extent as multi-regionalism theory" is meaningless.
Maybe you don't understand the question ? When I ask "to what extent is
X true", what I'm asking is "what are the aspects of X that are true ?".
"Early humans exploited the ocean intensively enough that it affected
their evolutionary development", which you've said in another post, is
actually a decent answer to the question, in that it IS an answer to the
question. It's too vague to be very useful though.

Again with the thing about my opinion on the topic being dependent on
what you write; what does that even mean ? Why would you think it is ?
No JTEM, your being completely incomprehensible in your writings doesn't
affect my opinion on anything but your ability to be comprehensible. It
DOES, however, affect my ability to respond to you coherently. It's
called "communication".
Like this : "It's not necessary for me to explain anything in minute
detail before anyone else can voice an opinion."
If you couldn't give a shit less about the opinions people voice what
does it matter how much detail you explain things in ? In fact if you
don't care whether people voice an opinion or not, why do you post in a
conversational medium ?
JTEM's minimialistic formulation is no formulation at all.
#1. What early ancestors exploited oceans in what location in what
way?
#2. How long and in what way significant? In order to have a
significant impact on our evolutionary development, those early
ancestors must have been the specific population on the direct
ancestral line to modern humans and must have had such a major pattern
of exploitation as to change significantly anatomical and
physiological characteristics. Wading in water to acquire aquatic
creatures as food sources isn't going to do the job.
Does it have to be an ocean shore?
why not?

which bits? Upright stance? body fat? diving reflex? hairlessness?
sweating? And when did the aquatic bit actually happen? It seems
little more than a Just So story to me.

Quite the opposite. It appears that we evolved to exploit the
oceans -- everything from hairlessness to our webbing. Even
our upright posture and larger brains fit the model -- just
becoming upright is a cheap, efficient means for becoming
taller, allowing you to wade in deeper water (like during
high tides), and sea food isn't just filled with protein, but oodles
of that brain-building stuff.
Yum.

Ironically, the argument is better and nobody is interested in
looking for any evidence.
(It's under water)
But lets look at the Savannah nonsense, with it's "Endurance
Running" joke. That goes something like: The climate changes,
the environment changes and our ancestors dropped the hair,
picked up rocks and chased down prey until it dropped.

Hmmm.... this is idiocy. We know there were glaciers. We know
that there were changes to the environment. In fact, these things
are built into the status quo nonsense. That part at least isn't
speculation at all. For the last few million years at least the
earth has been seeing alternating periods of warm & ice.
> And it's a pretty feeble version of MR.
You said it: It's Multi Regionalism.
Strangely enough, most humans are capable in varying degree of
accuracy to attribute correct mental states to the people they
interact with, based on observing their external behaviour.
Even some of the other primates have that ability, if in rudimentary
form: Premack, D. G. & Woodruff, G. (1978). Does the chimpanzee have a
theory of mind? Behavioral and Brain Sciences, 1, 515-526.
Of course, the ability varies between people, and to some it might
well appear magical: Baron-Cohen S, Leslie AM, Frith U (1985). "Does
the autistic child have a 'theory of mind'?" Cognition 21 (1): 37�46
And as I said in the rest of the paragraph that you snipped (along with
the many other paragraphs that made up the rest of the post), "water"
isn't a "particular" environment, it's a very vague word that can
describe many, many, many different environments. Moreover, "coastlines"
isn't even one of those environments. It's a transitional environment
that has some water, some land, shares features with all-land and
all-water environments, but also has its own characteristics. Organisms
that exploit this environment aren't adapted to "water", they're adapted
to coastlines. As far as water-adaptation goes, this translates into a
range going from fully water-adapted to fully land-adapted. Early humans
could perfectly well exploit the coastlines intensely while being in the
latter part of that range.
It's almost appropriate that you snipped the rest of the post, because
really it all boiled down to that : you've been picking different,
kinda-related concepts and putting them together in a paragraph as if
they were logically connected when they aren't.
All you list are inverts that live in water. Not a valid comparison to
humans.
Clams pretty much sit still and filter feed. Humans aren't going to lay
at the bottom of an estuary and filter feed all day as sessile aquatic
organisms are they? Shrimp can do that spastic undulation thing and move
about pretty good by flexing the tail, and are quite adapted to swimming
in water with specialized legs:
http://www.dnr.sc.gov/marine/pub/seascience/shrimp.html#loco
I think aquatic apes would be more comparable to other mammals like
dolphins, whales, and seals which all are good at swimming fast. Hippos
lumber around and might not be the best swimmers, but they don't have to
be because...they are hippos. Nobody messes with them. Humans in water
are susceptible to gators, hippos, sharks and other baddies.

You are arguing for a theory that is not well received. You should
expect people are going to express skepticism.
>the autistic child have a 'theory of mind'?" Cognition 21 (1): 37�46
This is all correct in assuming that the people you interact with have
normal intelligence, reasoning powers, and mental states.
Unfortunately, your recent instance inferring some insight into
another's mind fails in these regards.
o_O
What feelings ?
Your reading comprehension seems to be on par with your ability to
express yourself. But then, it would be.
If you want some positive statements on Aquatic Ape theory, here are a few :
- Things like hairlessness, webbed fingers, upright posture and the
ability to hold one's breath are quite significant physiological
characteristics that would only evolve from a very important driver. If
they were going to evolve from, say, humans swimming, those humans would
be swimming almost all the time.
- The way humans have historically exploited coastlines is very
different from swimming almost all the time. In fact it has historically
involved very little swimming at all. The main exception I can think of
is pearl divers. They're a tiny minority of humans and live in a very
different environment from early humans. Moreover, they HAVE got
physiological adaptation to diving (whether evolutionary or plastic)
that other humans don't share. This suggests that humans can evolve (or
plastically adapt) for diving more than they have, and that they can do
so fast. So if early humans had been diving enough to have an
evolutionary effect, that effect wouldn't have been subtle.
- If we do assume always-swimming pearl-diving early humans, it isn't
clear how this would result in the combination of upright posture,
webbed fingers, hairlessness and ability to hold our breath that we
have. Most aquatic animals aren't hairless; actually, isn't it just the
cetaceans ? Who are big (but that's OK, we're big too), and are VERY
aquatic. It is completely ridiculous to suggest humans used to be as
aquatic as cetaceans, but even if we don't it appears hairlessness is a
rather advanced feature for aquatic animals, so if our hairlessness came
from an aquatic lifestyle it would suggest we were very aquatic.
Similarly, our upright posture is a very significant evolutionary
change. It is even less clear how that would evolve from an aquatic
lifestyle, given most upright aquatic animals seem to be diving birds
and most humans who go into water don't do so by diving from a great
height. If one were to seriously propose that the upright posture
evolved from an aquatic lifestyle one would need to give some mechanism
for it. But if it DID evolve that way, the fact that it's such a
significant evolutionary change suggests that the aquatic lifestyle was
just as significant, i.e. humans were very aquatic indeed, for a long time.
On the other hand, our fingers aren't very webbed at all. It's hardly
appropriate to even call them "webbed", especially compared to other
apes who also have large palms. In fact, given our hands are so similar
to other apes' hands, it is extremely unlikely that they evolved by the
same pressures that gave us our hairlessness and upright posture (in
which we are unlike other apes). So in other words, if we were indeed
aquatic our webbed fingers are unlikely to have anything to do with it.
But if we were aquatic, how come we don't have much more webbed fingers
than we do ? That suggests a marginally aquatic lifestyle at best.
Same thing with holding our breath. Tons of non-aquatic animals can hold
their breath, and actual diving animals can hold their breath for much
longer than we can. They also have other diving adaptations which we
don't or barely have. This suggests that if human evolution was ever
influenced by an aquatic phase it would have been marginally aquatic.
So while every one of those traits could be attributed to aquatic
adaptations if we squint, their combination is inconsistent.
- When we look at how humans have historically exploited coastlines it
appears that we we were to have evolved to do so it would be as coastal
land animals, not aquatic animals. The kind of adaptations we'd expect
would be less related to water and more related to, say, salt tolerance.
- While it is extremely likely that humans evolved near water (although
I'd expect rivers to be as significant if not more than the sea), and we
might even have some specific adaptations related to that, it is highly
unlikely that the most important adaptations that distinguish us from
other apes such as hairlessness, upright posture, speech, intelligence
etc came as a result of an aquatic lifestyle. There is no real evidence
or mechanism for it.

Again with that bizarre conceit that my opinions are based on yours. Weird.
Except that by the time you're wading neck-deep you're better off
swimming. You have more mobility, and since you need to bend down to
pick up or catch things anyway there's no particular need to be upright.
And "wading" and "swimming" are extremely different water-related
lifestyles. Wading organisms are more land-adapted than water-adapted.
Why would wading early humans evolve hairlessness ?
Isn't the main idea that certain traits are explained by sustained
aquatic activity in our ancestors, ie the selective pressure that lead
to trait X is sustained aquatic activity? Or do you not care about
that?

Strangely, you're full of shit, beginning with the fantasy that
you're interacting with me. Secondly, if anyone here is even
aware of my position they have yet to make that much clear.
When one is incapable of accurately paraphrasing the words
spelled out in front of them, the odds of them correctly predicting
a mood -- much less intentions -- are beyond "Low."
What does any of this have to do with an aquatic ape nonsense? At the
time you mention, the passage did not require swimming.
