1
AGST 3000Lecture 3Domestication of Animals
and Development of Irrigation
2
Domestication of Animals
  • I. Herd animals (cattle, sheep, goats)
    domesticated by seed planters
  • II. Dooryard animals (dogs, pigs, geese,
    chickens, ducks) domesticated by vegetable
    planters.
  • III. Man may not have begun to keep animals for
    practical reasons inborn tendency for keeping
    pets.

3
Domestication of Animals continued
  • VII. Cattle are most important livestock
    accounting for
  • A. 50 of the worlds meat
  • B. 95 of the worlds milk
  • C. 80 of the worlds hides
  • D. important draft animals (oxen)
  • E. originated in Central Asia, spread to
    Europe, China, and Africa around
  • 9,000 BC

4
Domestication of Animals continued
  • IV. Young animals tend to become attached to
    people due to imprinting tendency to follow
    first living thing seen or heard.
  • V. A state of mutual indifference between man
    and wild animals may have been requirement of
    domestication.
  • VI. Totemism may also have encouraged
    domestication.

Domestication of Animals continued
  • VIII. Man had to develop methods to harness the
    full power of draft animals
  • A. i.e., horse pulled 4 times more than man,
    increased to 15 times with a harness
  • IX. Western Hemisphere development delayed due
    to lack of herd animals
  • A. i.e., failure to invent wheel, plow, arch,
    rotational devised water wheels,
  • etc.

7
Irrigation
  • I. Irrigation developed by civilizations in
    arid/semiarid regions practicing seed culture.

8
Irrigation continued
  • II. Irrigation was vital to the growth of
    civilization in both hemispheres.
  • A. Development of engineering skills spurred by
    technical aspects of diverting river water,
    draining marshes, building levies and dikes and
    canals.
  • B. Mathematics and astronomy developed as a basis
    for measuring land, time, and seasons.
  • C. Modern calendars developed in Egypt around
    6,000 years ago (Egypt remains the longest
    lasting irrigation based society.)

9
Irrigation continued
  • III. Irrigation was successful over time where
    annual flooding leached excessive salts and
    replenished soils through siltation.
  • IV. Average life-span of irrigated societies was
    40 to 60 generations (1,000 1,500 years)

10
Man lost his innocence with the agricultural
revolution.
  • Why?
  • I. Because man does not have to accept the
    environment.
  • II. Man can adapt the environment to his purposes
    and needs.
