Re: Q for Lee O, desert running

Lee: The
difference between Marc's example and the running example is that the
tools that processed the bones are found nearly everywhere in Africa,

Wait a minute tiger! I'm happy to accept that some stones were used to
snap some bones.
But that doesn't take fancy tools, chimps do similar stuff with
pebbles, breaking nuts, right?

How do you know that the stone tools esp. hand-axes were not
transported to the sites via dug-out boats during and after the rainy
season? Or that the hand-axes weren't used to craft dug-outs from
downed river trees, similar to current primitive tribal methods using
steel/iron tools? C4 plants grow best in wetlands.

African savannas were conquered via river boats from coastal regions
AFAICT, exactly in parallel with New World and Australian
colonialization by multiple migrations of humans. Only in dug-out boats
could humans enter without fear into the domain of the inland predators
and crocs etc. AFAICT.

yet there is not one hominid processed "pearl" to be found anywhere.
The first tools to show up are associated with antelope bones, tortoise
shells, and ostrich shells (all suggest areas of C4 plant growth, which
is exactly what is found in the isotope composition of early Homo
teeth). That is the null hypothesis (for all that transpired before)
until proven otherwise. No aliens need apply :-)

To summarize what I am trying to think... I am interested in a sort of
coherent, complex & dynamic, timeline of human development. I think we all
want that. How did we become this thinking being? and not just another
chimp? Does the chimp "think?" and etc.
