domestication of animals is distinct (different) from taming
- taming = conditioning or changing the behavior of a wild animal to accept human presence
- taming does not involve genetic modification via breeding
an animal is "domesticated" when traits are "selected for" by humans through breeding

originated in North America 40-50 million years ago, and spread to Asia
wild camels were killed off in the Americas by humans during early arrival periods to North America (Native Americans)
domesticated in central Asia approx. 2,500 BC
were in use in Middle East by 900 BC
introduced to Africa approx. 300 AD
Camels were used extensively for trans-Saharan trade by 600-700s AD
- and were essential for spread of Islam

particularly useful in the Central Eurasian "Steppes"
- high, flat, grassy lands
wild horses have unique ability to break through snow and ice in order to find grasses to eat
- due to the unique bend of horse front legs, horses can "kick"
horse milk was a primary source for Vitamin C for steppe nomads

domesticated in Western South America
thought to have been an essential element in spread of agriculture in western South America for its dung which was used as fertilizer
used extensively by the Inca for food, milk, fiber (fur) and transport
