Weakened by drought and/or mired in mud. that wasn't
so hard to figure out...

Why should the fast quadrupeds be more likely
to suffer drought, and be mired in mud, than
the slow bipedal primates?

Because they're weakened by drought? Predators,
hunters, take advantage of this.

Yeah, yeah. That's why, for the past 4 million
years or so, there have been groups of hominids
at every African water-hole, out-competing the
lions, etc., gradually getting so much better at
killing the prey that all the other predators went
into extinction two million years ago.

Predators today still hunt at water holes. You knew that, didn't you?

In PA it all makes sense.

And how do you ambush fast prey on empty
barren flatlands?

The landscape as it looks *today* would have looked
different *then*.

Very good! You're learning. From the article

He points to a pile of bones - the remains of a buffalo that has desiccated in
the heat.

"It came here to drink and then it died. If the droughts continue, this will
become an annual ritual."

Animals weakened by drought...

That is a DRIVE -- needing hundreds or thousands
of hominids. Do you claim that there were such
numbers on the African savanna at that time?

Hundreds not needed, much less thousands.

Villa, a curator of paleontology at the University of Colorado Museum of Natural
History, told Discovery News that other evidence suggests Neanderthals hunted
the giant mammals, but not as directly. At the English Channel Islands, for
example, 18 woolly mammoths and five woolly rhinoceroses dating to 150,000 years
ago "were driven off a cliff and died by falling into a ravine about 30 meters
(over 98 feet) deep. They were then butchered."

Nearly 10,000 years ago, 50 metres beneath the surface of what is now North
America's Lake Huron, hunters set an ambush. Caribou were herded through stone
corridors towards archers that lay waiting behind low parapets.

No bones or drawings have been found to tell this ancient tale. Instead sonar
mapping has given researchers detailed views of the lake floor, which flooded
8000 years ago, preserving a Pompeii-like snapshot of local human history.

Go look up buffalo jumps and sheep traps...

floor was covered in tens of thousands of
these 'tools'. They would have been visible
to any hominid from half-a-mile away. To
anticipate your claim that they might have
buried some (which is not suggested in the
report) -- why would the hominids bury so
many in locations where they could never
find them again?

Buried? huh? Why would they bury them?

I was merely anticipating your possible
answer. But I see that you go for the most
dumb: i.e. they made new ones and carried
them huge distances, even though they knew
that they could see plenty on the site.

You still have not explained why they'd bury them... they get covered with sediment
when the watger levels return.

'quarry' (probably dozens of miles away) found
Transport of lithic materials over long distances is
already known and from older sites. This is no
surprise.

WHY keep in bringing fresh 'tools' to these
sites -- when there are tens of thousands of
them already there?

Over time water returns and covers the areas once
exposed by drought? Duh? And drought is cyclical? Duh?

The huge 'hand-axes' are found on the lake floor.

*Dry* lake floor.

" . . Equally remarkable is that the dry lake floor where they
were found is also littered with tens of thousands of other
smaller stone-age tools and flakes, the researchers report.

Professor David Thomas, Head of the School of Geography and the
Environment at the University of Oxford, said: ?Many of the
tools were found on the dry lake floor, not around its edge,
which challenges the view that big lakes were only attractive
to humans when they were full of water. . ."

Take a good look at the shape of those huge 'hand-axes':
