Plant domestication began around 10,000 years ago in Mesopotamia where early humans domesticated wheat, barley, lentils and peas. A key early site of plant domestication was the Balsas River valley in Mexico where corn was first domesticated from teosinte plants. Rice was independently domesticated in China from wild rice and in Africa from a different species of wild rice. Beans were domesticated in both Mexico and Peru from wild beans, and potatoes were first encountered and eventually domesticated by peoples in the Andes mountains of South America. Plant domestication was a major development that allowed nomadic humans to settle down into agricultural societies.

2. What is plant domestication?
 Plant domestication
is the process in
which plants have
been evolve into crop
plants through
artificial selection.

3. How did it started?
 People first domesticated plants about
10,000 years ago, between the Tigris
and Euphrates rivers in Mesopotamia.

4. Domestication in Mesopotamia
 The first domesticated
plants in Mesopotamia
were wheat, barley, lentils
and types of peas by
Eastern Asia, parts of
Asia,from Africa, north and
South America.

5. GENETICALLY MODIFIED ORGANISM
(GMO)
 A GMO is any organism whose
DNA has been altered using
genetic engineering techniques.

6. “BALSAS RIVER”
 This river, was one of the earliest corn
growing site in México.
 It is known as the cradle of corn
domestication.
 Time ago there were found over 10, 000
cobs of teosinte (a plant similar to corn).
 Recently was found that México could be
the first site were corn was ever
domesticated.
 This river flow through a lot of places, which
are:
 Guerrero, Puebla, Morelos and México.

8. BALSAS RIVER
 Balsas river is a very important lace in the story oif domestication of plants,
because it is the cradle of one of the most important things that now we use as
food as fuel as a material for bags, and a lot of things that now we use.

10. ASIAN RICE
 There are two types of rice the African and
the Asian.
 It was domesticated since 8000 BC
 Asian rice was originated in India, Thailand
and Southern China
 It was first domesticated in the region of
the Yangtze River valley in China

11. ASIAN RICE

12. African rice
 African rice was independently
domesticated ~3000 years ago in the
Niger River Delta
 It's used in a ritualistic context and as a
treatment in African traditional medicine.

13. AFRICAN RICE

14. Did you know…?
 That rice is known as the oldest food still consumed today
 There are over 40,000 varieties of rice
 Asia consumes and produces a 90% of the rice
 September is National the “Rice month”

15.  There are about 25000 diferents species of
wheat the archeologies dont realy know
when wheat was domesticated but they say it
is about 12000 and 23000 years ago and it
took about 5000 years to be domesticated.
WHEAT HISTORY

16. Where was wheat domesticated
 Genetist agree that wheat was domesticated in the mountain regions of what is
today turkey also wheat makes two of the 8 founder crops.

17. Civilizations that depend on wheat
 The oldest civilization that is know to depend on wheat is the people off Syria but
there are remains of wheat in china,Greece,rome and England

18. Difference between wild wheat and
domestic wheat
 The oldest wheat also know as
wild wheat is the breed of wheat
that wasn’t
Domesticated the difference between
the two crops is that the wild one
has smaller seeds and also grows
slower than the domestic one is also
know as eacorn

19. CORN
 Corn was domesticated from its wild grass ancestor,
8,700 years ago, in Central Balsas River Valley.
 Ranere said that studies, confirmed that corn was
derivate from teosinte, there were 5 species of
teosinte in México, but the teosinte specie that was
closest to corn was Balsas River teosinte.
 Since that corn is used, for a lot of things.
 In the next page we can see how does it evolve.

20. CORN DOMESTICATION

21. CORN DOMESTICATION.
 In the last page, we could se how does the corn evolve.
 The first thing we could saw that the first plant was so different to the corn that we
actually know.
 And the second thing was the actual corn, it has been a lot of changes, form the
teosinte to the corn we know now, and what cause this changes is what we call
plant domestication.

22. The bean
 The common bean is one of
the most important domestic
legumes in the world.

23.  The global harvest today has been
estimated at 18.7 million tons and it
is grown in nearly 150 countries on
an estimated 27.7 million hectares.

24.  Beans were domesticated in
two places: the Andes
mountains of Peru, and the
Lerma-Santiago basin of
Mexico.

25.  The main difference between wild and
cultivated beans are, well, domestic beans
are less exciting. Of course, there is a
significant increase in seed weight.

26.  The study suggests that the wild form spread
from Mesoamerica, into Ecuador and Columbia
and then into the Andes, where a severe
bottleneck reduced the gene diversity, at some
time before domestication.

27. POTATO DOMESTICATION
 The potato as we know it today
is far different than the plant
first seen by humans many
years ago.

28.  The first people to encounter the
potato were those located along the
west coast of South America towards
the end of the last Ice Age.

29. Did you know…?
 During the Alaskan Klondike gold
rush, potatoes were practically worth
their weight in gold. Potatoes were
valued for their vitamin C.

30.  In October 1995, the
potato became the first
vegetable to be grown
in space.

31.  The spread of potatoes
from Andean highlands
to the coast and the rest
of the Americas was a
slow process.

32. CONCLUSION
 Plant domestication was clearly one of the most important advancements of the
man, once agriculture developed it spread all around the world and it let nomads
to be sedentaries.
 Thats how nomads stop walking around and stay in one place and plant their own
food and let small groups grow bigger to what we are now.
