Creation of Man
LECTURE PART THREE
THE CREATION OF MAN
The Scientific Evidence for Human Beginnings
--- Three lines of evidence:
• Cave Art
• Tools and artifacts
• Fossil bones and skeletons
--- As we go, look for Human activity.
What sets humans apart?

Creation of Man
A. The Scientific Evidence for Human Beginnings
 Fossil tools – stone, bone, wood, etc.
"It has often been said that no animal uses any tools."
Charles Darwin, Descent of Man (1874)
Monarch Migration
Must be in the genes!
Use of tools:
In the Genes
or Learned behavior?
Neanderthals:
Mousterian 300,000–30,000 BP
Aterian: 80,000-40,000 BP
Tool use?
Genes? Innovative? Rote?

Creation of Man
A. The Scientific Evidence for Human Beginnings
 Fossil tools – stone, bone, wood, etc.
Facts to keep in mind…
• Tools are not uniquely human or even hominid
• There is an extensive fossil record of tools showing
gradual advances over time
- At what point do they indicate human activity?
Wooden spear cut/shaped from log
(Schöningen 380,000-400,000 BP, discovered ca. 1995)
A simple point
flaked from flint
(Mousterian 300,000-30,000 BP
scraper
spear head
Aterian Tang Tools
(N. Africa, 80,000-40,000 BP)

 Fossil tools – stone, bone, wood, etc.
Aurignacian Tools
40,000-26,000 BP
Chatelperronian tools
35,000-29,000 BP
Gravettian Tools
32,000-22,000 BP

 Fossil tools – stone, bone, wood, etc.
Summary:
• Evidence of Sustained Rational Innovation does
not appear until 40,000 BP with the Cro-Magnons.
• The Stone tools of Neanderthals showed only
minor innovation over vast periods of time.

Creation of Man
 Skulls: Neanderthal, Cro-Magnon, and Modern Human

Neanderthal & Human Pharynx

Creation of Man
 Skeletons: Neanderthal, Cro-Magnon, and Modern Human
Why Neanderthals are not considered Human:
(Ongoing – lots of info in the past 5 years)
DNA evidence:
• Genetic DNA
96-99% match (depending on whom you ask!)
• Mitochondrial DNA (comes from mother only)
-- Neanderthal mtDNA
"half-way between human and chimp"
Warning:
• These Percentages are just glosses –
really need the details!
• Human genes "from Neanderthals" is
another gloss! Again, need the details!
CONCLUDE: Humans likely did not mate with Neanderthals.
(some say they didn't even co-exist! I think they may have.) 16
Creation of Man
 CONCLUSIONS:
• Summary of the Creation Narrative
- The Silent Voice
- The Four Geneses
• Big Bang
• Creation of First Life (Bacteria)
• Creation of Eukaryotes
• Creation of Man
- The Four Paradoxes
• Combinatoric Paradox
• Eigen Paradox
• Levinthau Paradox
• Regulatory Paradox
17
Creation of Man
 CONCLUSIONS:
• Creation of Man
All lines of evidence indicate that modern
humans first appeared 40,000 – 30,000 BP.
Cave Art: Definite human activity by 32,000 BP
Tools: Notable lack of innovation prior to this
Bones: Neanderthals not human ancestors.

Creation of Man -- SUPPLEMENTARY SLIDE
A. The Scientific Evidence for Human Beginnings
 Remark on Evolutionary Rates of Change
"Realize of course that the 10,000-100,000 time window for the emergence
of homo sapiens is a mere blink of time in which profound changes occurred.
How could this possibily have been accounted for by natural, undirected
change?"
Ian Tattersall, Masters of the Planet, (2012)
Remarks on Generation Counts.
-- Chimps to Humans (100,000-200,000 generations)
-- 35 million single nucleotide changes
-- 5 million insertion/deletions
-- Chromosomal rearrangements (24 to 23)
-- Neanderthal to Cro-Magnon (8,000 generations)?
-- Cro-Magnon to Human (2,000 generations)?
-- Ur to Modern Human (200-300 generations)?
Comparison on Generation Counts
-- E-Coli (20 minutes): 100,000 generations in 4 years
-- Cyanobacteria (1 day): 100,000 generations in 275 yrs.
• Since first life (3.9 Ba): 1-2 trillion generations
