The earliest fisherpeople and their shell tools
Meghan Zulian FoodOcean Feb 20 ?year

As rising atmospheric CO2 warms & acidifies the oceans, in many places shellfish will struggle to survive.
Though many of us are not dependent on these critters in the modern day, it’s worth asking the question:
how long have humans & our predecessors relied on shellfish?

A study by researcher Dr Paola Villa cs found :
in Italy, H.neand. were not only eating shellfish 100 ka, they were using shells as agricultural tools.
Of the 171 modified shells examined from an archaeological cave site, most were reconfigured to be used as “scrapers” or “flakes”.
Based on the state of the shells & the marine spp found on them, researchers believe:
nearly 25% of the shells were collected live by the Neanderthals from the sea-floor.
The researchers point out the mutually exclusive occurrence of stone & shell tools suggest: when stones were scarce, H.neand. turned to shells.

These findings suggest:
H.neand. were swimming in coastal waters, and collecting resources long before H.sapiens arrived.
If H.sapiens are so advanced, then why do we not see the trends of them using shellfish for tools at this time?
A study from Verhaegen & Munro suggest: the specialized ear-bones & heavier skeletons of H.neand. made them more efficient swimmers.
Their conclusions agree with other studies:
H.neand. were eating shellfish long before H.sapiens, in some cases as many as 150 ka (Cortés-Sánchez cs 2011).

Their presence indicates that these shells were collected from the deep.

As rising atmospheric CO2 warms & acidifies the oceans

To prove that science is dead:

NASA insists that CO2 stays in the atmosphere for a minimum of
300 years -- 300 to 1000 years -- which means pretty much ZERO
CO2 produced in the entirely of the Industrial Revolution has ever
left the atmosphere... AND at the same time it's turning the oceans
into acid even though it's not.

You can buy a simple PH test off of Amazon, or maybe in a nearby
shop, and go test the PH level of the sea all by yourself. It's not
acidic.

And, like I said, according to the propaganda -- what were are
ordered to believe is science -- none of it has left the atmosphere
anyway. Not yet.

how long have humans & our predecessors relied on shellfish?

I imagine it's been MILLIONS

More than 8 million. Probably 10 or possibly 20. It depends on how
you define our predecessors and what model you support for things
like bipedalism.

I do kind of favor your island ideas. Insular Dwarfism is well known.
What isn't well known is Insular Gigantism. Google it, you'll find
sources claiming that it commonly precedes Dwarfism.

The idea I love is that plate tectonics and/or climate fluctuations
stranded one or more population on an island without predators.
Competing only against each other, this led to gigantism. But instead
of exhausting resources & spawning dwarfism, they exploited the
sea -- shellfish in particular -- and fueled even more growth.

"High protein diet," and all that.

A study by researcher Dr Paola Villa cs found :
in Italy, H.neand. were not only eating shellfish 100 ka, they were
using shells as agricultural tools.

Oh, that's *Way* too recent to be significant!

No, sorry, you were right all along...

NOTE: The above link is consistent not only with Aquatic Ape but
with populations pushing inland. That's the model. They followed
the coast and then for any number of reasons followed freshwater
outlets or transitional wetlands inland, eventually adapting to their
new environments. This resulted in permanent, unique populations
across Eurasia and deep into Africa.

...of course none of this is supported by the good Doctor but
nobody is perfect.

No doubt Miocene Hominoidea c 25 Ma were already "BP":
wading+climbing vertically in swamp forests, google "aquarboreal",
they might have (occasionally?) included mangrove oysters into their diet?
But they weren't yet molluscivores IMO:
systematic/frequent shellfish-diving (only Homo?) was only early-Pleistocene?

1) Hylobatids after 25-10 Ma followed the N-Tethys Ocean coastal forests -> East -> SE.Asia.
2) Pongids after c 15 Ma followed, forced hylobatids higher into the trees: brachiating?
3) Pliocene Homo (after c 5 Ma) followed: was forced by pongids deeper into the sea: shellfish-diving??

Nice to see there are still a few intelligent people here...
One must be incredibly stupid to believe one's ancestors ran after savanna antelopes. :-D
