CYLES OF WARMING/COOLING
• Geologic Record shows that Earth has gone thru multiple cycles of Cooling/Warming
• Cycles typically last tens of millions of years!
• Last MINIMUM earth temperature was about 2 mya
• Earth has been warming ever since
Historical AVERAGE temp of Earth
Historical MAXIMUM temp of Earth
Historical MINIMUM temp of Earth
GLACIATION IN LAST 800,000 YRS• After the Last Global
Cooling Period had reached it’s maximum, temperatures started rising
• Even with generally rising temps, there were periods of cooling; 4 Glaciation Periods in the last 800,000 years
• Let’s focus on the last one: Wisconsin
Years BP
CO2, ppm
MIGRATION TO EUROPE• Homo Sapiens is thought to
have started leaving Africa around 70,000 yrs ago
• Glaciers were nearing their maximum for this period
• When amount of glacial ice is up, (MAXIMUM)
Sea levels are down, (MINIMUM)
• Therefore Continental Margins will be wider, ocean/sea crossings smaller
Amount Glaciers
is up!
Sea-levels are down!

Two migration theories of Homo

1.Migration north into Israel/ Palestine
2.Migration across Bab al Mandab Strait to Yemen and points beyond

BUT…
MT. TOBA, INDONESIA, ERUPTION• 75,000 yrs BP, Mt. Toba Volcano exploded;
largest explosion on earth in 25 million years• Blew 2,800 times as much as ASH into the
atmosphere as Mt. St. Helens (2.8 times the last explosion of Yellowstone Supervolcano)
• Ash suppressed temperature of Earth by 7 degF (up to 27degF at northern latitudes!)
• One theory states that 90% of Homo Sapiens that existed at the time died, leaving only 10,000 or so to re-populate the Earth!
This is known as the“Toba Catastrophe Event”

WHY WAS DANUBE CORRIDOR IMPORTANT?
• Animals graze in valleys
• Source of water always near-by
• Major East-West corridor
Add mountain ranges…• “Path of least resistance”- avoid hilly/mountainous routes
But, there was an additional
reason…
GEOLOGY PROVIDED SHELTER!
England
France
Germany
EUROPE IN THE JURASSIC• Shallow seas covered
most of Europe during this Period
• Shallow seas will often form limestone reefs
• Limestone is carved out by weathering & erosion = CAVES
• Weathered sections become natural shelters!

It burned 2oz of deer fat; this one had deer fat still
in it when found!
LA GROTTE DE LASCAUX 1,963 registered Paleolithic paintings 60% of all pictures involve horses
Only 1 bird, 1 bear, 1 rhino, and 1 human are depicted
CRO-MAGNON
CRO-MAGNON• Cro-Magnon is an informal name for the
first early modern humans
• They were robustly built, and powerful, body was generally heavy and solid with a strong build
• They differed from modern day humans in having a more robust physique and a slightly larger cranial capacity
• Cro-Magnon could probably speak
• Cro-Magnons could have been medium brown to tan-skinned as light skin evolved independently in both the Asian and European lines, didn’t appear in the European line until about 6000 years ago
CRO-MAGNON• It is unknown why they painted the
caves in and around Lascaux
• Three predominate theories emerge:
• Paintings might have been done to promote good luck in hunting by the individual hunters
• Paintings might have been done by a Shaman as religious preparation for a big hunt asking for protection from harm (average life span of Cro-Magnon is thought to be about 36)
• Paintings might have been a result of eating hallucinogenic mushrooms or other substances
