Early Human Beings

May have left Africa—Why? Probably diseases, population

pressure.

We are all genetic brothers and sisters, regardless of skin color.

• We all share a common mother (proven D.N.A)

• A bottleneck of ancestors (maybe numbering less than 100 people) occurred thousands of years ago

• This means Mr. Mason is your brother. • Yuck.• Our last common ancestor lived only 600

years ago

The Ice Age

• Ended about 10,000 years ago—but was the coldest only 20,000 years ago!

• Huge ice sheets covered the land• Changed the Earth’s landscape• Created Norwegian Fjords, settlements along

the ice sheets• Many inhabitants lived in caves—drawing

pictures of now-extinct animals

The Continent of Europe

• The Mediterranean shielded the land from major ocean storms

Island Hopping

• The relative close proximity of islands made it easier to navigate by land sights

• Island hopping: Greek islands to Crete to Malta to Corsica to Elba to Capri

• Still, being a sailor was risky business!

• If we could drain the Mediterranean, it would be full of shipwrecks.
