This wet aper is delusional. He needs to lie about evidence he doesn't
have.

Here is factual evidence:

Marc and Sir Hardy have a lot in common. They both went on to
"spiritual phenomena"
during their later careers.

With Marc, of course, imagining evidence where it doesn't exist is
his
only argument.
The reason Marc doesn't cite (coco)nuts, crayfish, and semiaquatic
mountain beavers
from the professional literature is because this evidence does not
exist.


Eggs do exist in the early archaeological record, but the educated
reader knows these
are ostrich eggs (Roche 1999), a bird associated mostly with the
savannas and hot arid
climates where early Homo evolved. A savanna diet by early Homo is
further confirmed
by the C4 isotope record gleaned from the teeth of early hominids,
including some of the
earliest Homo yet discovered (Lee-Thorp 2001). This falsifies any
significant contribution
of the diet claimed by AAT.


The savanna existence of the earliest Homo can easily be traced by
the
number of stone
tools scattered about these arid regions. Cut marks on antelope bones
confirm once again
the C4 work of Lee-Thorp.


"Significant changes occur in human evolution between 2.5 and 1.8
mya. Stone tools first
appear, brains expand, bodies enlarge, sexual dimorphism in body size
decreases, limb
proportions change, cheek-teeth reduce, and crania begin to share
more
unique features
with later Homo. Although the two earliest species of Homo, H.
habilis
and H. rudolfensis,
retain many primitive features in common with australopithecine
species, they both share
key unique features with later species of Homo. Two of the most
conspicuous shared derived
characters are the sizes of the brain and masticatory apparatus
relative to body weight.
Scaling features to body weight is essential because species of early
hominid vary so substantially
in overall mass that unscaled characters may cause incorrect
assessments of relationship.
One unexpected complication in the transition from australopithecine
to Homo is the apparent
fact that the postcranial anatomy of H. habilis retained many
australopithecine characteristics
in contrast to the more human-like body-plan of H. rudolfensis and
all
later species of Homo."

Environment and Behavior of 2.5-Million-Year-Old Bouri Hominids
SCIENCE VOL 284 23 APRIL 1999


"The Hata Member of the Bouri Formation is defined for Pliocene
sedimentary outcrops in the
Middle Awash Valley, Ethiopia. The Hata Member is dated to 2.5
million years ago and has
produced a new species of Australopithecus and hominid postcranial
remains not currently
assigned to species. Spatially associated zooarchaeological remains
show that hominids acquired
meat and marrow by 2.5 million years ago and that they are the near
contemporary of Oldowan
artifacts at nearby Gona. The combined evidence suggests that
behavioral changes associated
with lithic technology and enhanced carnivory may have been
coincident
with the emergence of the
Homo clade from Australopithecus afarensis in eastern Africa."
