But the fact remains, early Homo was utilizing antelope bones on the
savanna 2.6 Ma, long before we got to the moon. So yes, our ancestors
lived on the savanna.

Our ancestors?? I guess you mean some hominids lived on savanna. OK, no
problem. In that case, obviously (see physiology of apes & humans) near the
rivers/lakes there, where there was plenty of water.

No, water is where you find fossilized bone. Tools are also found
where water is scarce, in dry stream beds for instance.


The point is that humans are superior to most typical savanna
dwellers:
"The earliest Eurasians preferentially occupied
grasslands and open scrub- and wood-lands, as in
East Africa. Homo ergaster/erectus in East Africa after 1.7 Ma is
associated with hot and dry conditions, and open
grasslands;

Usual savann-biases, answered in other post.

Yes, see modern runner above who runs down antelope in the heat of the
day.

its post-cranial anatomy, with its long
limbs was geared to long-distance walking across
open ground, and to heat dispersal through upright
posture (Dennell 2003:442)."

Yes, all wavanna mammals dissipate heat through upright posture... :-D

Yes, see hunter cited above who runs down antelope in the heat of the
day.


"At Olduvai the Acheulean sites tend to lie along
the former stream channels away from the playa
lakes (Hay 1967a, 1976)."
"Therefore, there is a tendency of Acheulian sites to appear away from
the lakes margins and mostly near fluvial contexts, in which stone
tools are widely predominant over faunal remains. A similar trend has
also been recorded for Olduvai Bed 11 Acheulian sites, and it is even
more pronounced during Bed III times (Hay 1976). This observation led
us to formulate what we have called the "ecological hypothesis of the
Early African Acheulian", which links this type of site to particular
ecological contexts (distant from lake margins)....." Dominguez-

OK.

" In fact, he walked and ran with better mechanics than we do today.
The mechanics of his femur, femur head, pelvis, and lower back are
superior to those of today.

Is this said about H.er.?? This is nonsense. They were much too heavy.

Says who?

Short tibias. Borad pelvises, long & more horizontal femoral necks, clearly
for ab/adduction. Not for running!!

That is not what the Turkana Boy monograph says. Cite your source if
you have anything different. If your ideas were correct, we would
still look like Lucy.


Hs (longer tibiae, narrower pelvis, shorter femoral necks, more veritcal
fem.necks etc.) are obviously much better runners than He, although still
less than +-30 km/hr (half that of horses) & with enourmous water & salt
consumptions.

Mr McLeay's run for his life began after at least three shots were
fired at the vehicle, narrowly missing him.

He said he ran barefoot for over five hours and covered about 30km.

"I was literally running for my life."

He was not able to see much with the grass about 3m high.

"Once I was in the grass I kept my head down ... It felt like my heart
was in my ears. It was very hard to hear anything."

He said he moved "very fast", running in bare feet for 5km without
stopping.

Reaching a game park area Mr McLeay was surrounded by antelopes, wart
hogs and buffalos but said he felt safe despite the wild animals. The
animals were not distracted by anyone else and so Mr McLeay knew he
was the only human there.


We have had to sacrifice some of that
efficiency of walking and running to give birth to children with
larger brains."

Other nonsense. Human childbirth is about as difficult as in monkeys, see
A.Schultz 1969 "The life of primates" Universe NY:154 fig.59: it's the great
apes that have rel.easy birthing (I guess mostly due to their recent iliac
elongation).

Schultz 1969? :-)



All this confirmed by the work of Donald Mitchell (cited in the book
'Quarry' by Noel Boas).
"He showed that even the slowest human runners could, with even a
slight head start, outrun lions, cheetahs, leopards, hyenas, and wild
dogs, not by speed, but by out distancing them."

:-D Run, my boy, run.

Yes, antelope on table beats cattails anyday.
