Hybridoma Technology ( Production , Purification , and Application )
Paleolithic Humans Relied on Hunting and Gathering
1. In the PALAEOLITHIC AGE, humans got all their
food from wild plants and animals in their
environment.
• They hunted wild animals like deer, wild pigs, and large
birds.
• They collected wild fruits, berries, and nuts.
• They fished and collected shellfish and crabs.
• They gathered wild tubers (root vegetables, like potatoes
and carrots), vegetables, and grains.
2. The Neolithic Age and
culture
10,000 years ago, there
was a slow process of
radical change in the
history of humanity!
3. Let’s read together on page 94.
What’s the name for this? What about this cereal?
4. Why do you think it´s called the Fertile Crescent?
Know these rivers: the Eurphrates and the Tigris
The Near East
5. Also, the Neolithic Culture
developed in:
• The Indo Valley in India
• The Huang-Ho Valley in China
• See page 94, locate on the map and
watch “Guns, Germs, and Steel”
20. Domestication changes how plants and animals
behave so that, over time, they end up looking
different from their wild cousins.
21. The domestication of plants and animals
dramatically changed the way humans
interacted with their environment.
Now, instead of merely living within their
environment, humans were managing it.
Domesticated animals
and plants now depend
on humans for their
survival.
24. oldest known textiles
• Linen made from the flax plant, is one of
the strongest fibers. It was found in what
is now southern Turkey from between
8000 and 7000 B.C.
• Evidence of woolen textiles comes from
the same area and dates from about
6000 B.C.
25. Even though POPULATION GROWTH was the
CAUSE of the adoption of agriculture, it was
also the RESULT.
As a result of farming…
1) More food is produced for more people
2) But more people are needed to do all the work required
So people began having more children to fill this demand.
Furthermore, hunter gatherers cannot have too many
children at a time people they are continuously moving. This
isn’t a problem for farmers.
26. • Question for end of class:
Where did American hamburgers really
come from?
27. From as few as 80 progenitors domesticated in southeast
Turkey about 10,500 years ago,[2] an estimated 1.3 billion
cattle are in the world today.[3] In 2009, cattle became the
first livestock animal to have a fully mapped genome.[4]
