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.

Some? Define some?

Define stone tool? a rock?


But that doesn't take fancy tools, chimps do similar stuff with
pebbles, breaking nuts, right?

Right, but what would that observation have to do with the distribution
of the tools?
There is nothing in this distribution that would back up any of Marc's
claims.

Marc has made many claims, which ones are at issue? None are in this
thread that I can see.




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

Try making a dugout with a hand axe and you will find out why they
weren't used in making dugouts.

See my response to Paul.

C4 plants grow best in wetlands.Citation?

C4 plants grow best when well watered and in sunlight, eg. cattails,
rice.
C4 plants compete better against C3 plants in open wetlands and open
savanna (fire/seasonal complex)

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.

Then how did all the stone tools get on the savannas a million+ years
ago?

Again, "stone tools" is a bit vague, no? What stone is not a tool in
the hands of a man or chimp?
I'm speaking of obviously crafted bifacial hand-axes and blade/flakes,
I don't know what you are referring to.

I consider three types of bifacial hand-axes:
1) Butted: Found water-side, used for dug-out construction primarily
2) Butted: Found elsewhere, used for bone splitting for marrow and bone
tool making
3) Non-Butted: Cores found at and near quarries, for flaking and
recycling
DD

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.
