Homo sapiens
Between 200,000 and about 100,000 years ago, people who were both anatomically and genetically “like us” emerged in eastern and southern Africa.
This is a reconstructed Homo sapiens skull, found in Israel. It has been dated to about 90,000 years ago.

From their African
homeland, Homo sapiens
groups migrated to…
…Where?

When early humans moved out of Africa, where do you think they went?

Which of the push and pull factors we identified might have caused early humans to move out of Africa?

That’s amazing!
Why were modern humans
able to move into so many
different environments? After all, no other
large animals had
spread so widely!
So what was so
special about us?
![Page 25: Unit 2 – Lesson 5 The Peopling of the Earth. Reviewing What We Have Learned…](https://reader036.vdocuments.us/reader036/viewer/2022062408/56649eff5503460f94c149bf/html5/thumbnails/25.jpg)
Language!
Homo sapiens had language
◦ so they could exchange complex ideas with each
other.
◦ and they could store and add to the ideas of
previous generations.
Because they swapped ideas, they kept finding
◦ new ways of doing things.
◦ new ways of living.
Language SharedIdeas
New Ideas
Learning
![Page 26: Unit 2 – Lesson 5 The Peopling of the Earth. Reviewing What We Have Learned…](https://reader036.vdocuments.us/reader036/viewer/2022062408/56649eff5503460f94c149bf/html5/thumbnails/26.jpg)
Language made collective learning possible.
The stores of knowledge
and skills humans built up
are called “culture.”
No other animal can store
and accumulate
knowledge and skills in
this way.
We call this ability
“collective learning.”
It is what
human history
is about!
It is what
makes us
special!

Lesson Summary
• Humans were able to move out of their original habitat while other species did not.
• Human migration over the planet took thousands and thousands of years.
• As humans migrated, they learned to live in more varied environments such as deserts and dense forests.
• Humans migrated to new biomes to find food, escape weather patterns, and find space for a growing population.
• Language might have developed in Africa, anywhere between 50,000 and 100,000 years ago. As humans migrated and moved, language likely became more complex and helped people solve new problems.
