"The cute, feel-good images of babies swimming freely in a pool, shown

the AAT video, have nothing to do with the real situation of predator
avoidance
in Africa. Ask the Dasenich or Turkana people who live around Lake
Turkana:
only visiting maniacs swim in that lake." Cameron Smith


It hinders fast running (even human
runners run with more horizontal spines).

More of Marc's rubbish, here is what real scientists say:

"The public was amazed at the prowess of the runners and even more so
when the papers reported
that there were better ones at home. One of them was called "The Tiger
of the Sierra"; he had run for
three consecutive days that same year, near Norogachic, Chihuahua,
covering a distance of 300 kilometers,
or 186 miles, of mountainous country."

"Specifically, longer, more linear bodies are better adapted
for heat loss in dry open environments, where evaporative
heat loss from sweating is very effective. All modern-day tall
"elongated"
African (e.g., Nilotics) are restricted to such environments."
Alan Walker and Richard Leakey editors.
1993 The Nariokotome Homo Erectus Skeleton.
Harvard University Press, Cambridge

"Two indepandent lines of research converged on the
conclusion that early Homo was an efficient runner, the first human
species to be so Leakey (1994:55)."

Mr. Karoha runs down another ill-equipped-for-savanna kudu.

"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; 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)."

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

"Just because humans have long legs doesn't make us less aggressive.
Rather, the longer legs are a product of humans' specialization for
distance running."


"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 (Donald Mitchell)."

"From our spring-loaded ligaments to our muscular behinds to our
ability to sweat,
the human body took the ideal shape of a long-distance runner starting
some 2 million years ago,
the researchers say. The long, lean build helped us scavenge widely
scattered kills
and could also have been an advantage when hunting down prey over long
distances."
"We're lousy sprinters, but we're really great long-distance
runners,"
said Daniel Lieberman, an anthropologist at Harvard University.
