"Marean figured the early people, probably women, had to trudge two to
three miles to where the mussels, clams and snails were harvested and
to bring them back to the cave."

The idea that Marean (et al.) had the faintest
idea of how far away the coast was at the time
is, of course, crazy. It might have been 100
metres. It might have been ten miles.

"Looking for early human remains, Marean and his crew homed in on the
caves at South Africa's Pinnacle Point. Much of Africa became
inhospitable during an ice age that lasted from about 195,000 to
130,000 years ago, leading to cold, dry conditions on the continent
that forced at least some humans to the coast. Many coastal caves were
cleaned out when sea levels later rose, but Pinnacle Point stayed high
and dry."

"The search for early human use of marine resources, supported by the
National Science Foundation, centered on the cave at Pinnacle Point
because of its position high on a cliff. Other seashore sites of early
human occupation had been inundated by the rise in sea level,
beginning about 115,000 years ago at the end of Africa's long desert
conditions."

Sea levels would have been low @164k:

The idea that Crowley would know anything about geology is, of course,
even crazier yet:

We are not talking about geology --
but about fluctuating sea-levels.

That's funny:

The fact that they have stayed more-
or-less unchanged in your lifetime
does not mean that _over_geological_
_timescales_ they do not fluctuate
hugely. While it has been well-known
for about five decades, that they do,
this fact has not yet been absorbed
into PA.

Cite your source.


At times the sea would have been
very close to this cave. At others,
it would have been far distant.

@164= Oxygen Isotope Stage 16 = distant

At which of them is it most likely that
local hominids would have carried
mussels and clams back to them?

OK, it's a tough question.

Only for someone who thinks chimps do not have the capacity to dig.

Tell you what, YOU do a little research on the sea level depths (any
good nautical chart should do it) off Pinnacle Point today. The meters
of ocean drop are known approximately for the different isotope
stages. Should be easy to check Marean's statement.
