The Geography of Livestock

Evolution of Human Diet and Domestication
📌 Around 2,000,000 years ago, early humans survived by collecting fruits, bark, roots, and insects, unlike other hominids like Australopithecus who relied more on lower-quality plants.
🥩 During an Ice Age, Homo sapiens survived scarcity by consuming animal meat and bone marrow, gaining crucial protein and nutrients that saved them from extinction.
🤝 Domestication is the process of training and breeding animals to coexist with humans for food or other value (eggs, milk, leather), leading to the establishment of livestock.

History of Chicken Domestication
🐔 Modern chickens descend from the red junglefowl, originating in areas from India through Southeast Asia (including Sumatra).
🇨🇳 The earliest definitive evidence of chicken domestication is from Hebei province, China, around 7,400 years ago.
🐓 For the first 5,000 years after domestication, chickens were primarily used for cockfighting and gambling, not consumption.
🥚 The first evidence of chickens being farmed and eaten dates back only 2,300 years in the ancient Israeli city of Maresha, based on butchered female chicken bones.
🌍 Due to domestication, chickens are now the most populous bird, with 19 billion raised for meat, equating to 2.5 chickens per human globally.

Origins of Cattle, Swine, and Turkeys
🐂 Domesticated cows trace their lineage back to the extinct auroch, with modern taurine cows likely originating from about 80 aurochs near Çaöynü Tepesi in modern Turkey.
🐄 A second domestication event resulted in indicine cows (zebu) near the Indus River in Pakistan, distinguishable by their humps.
🐖 Swine are domesticated Eurasian boars, likely first domesticated in the Tigris river basin (south-central Turkey), the same area as cattle domestication.
🦃 Wild turkeys originated in Mexico, but their name comes from the association with the Ottoman Empire (Turkey) due to trade links with the guineafowl.

Domestication in Western Asia and the Andes
🐑 Sheep, descended from the mouflon, were first domesticated by Mesopotamians 11,000 years ago in the region spanning the Caucasus, Turkey, Iraq, and Iran.
🐐 Goats likely descended from the wild bezoar ibex and were domesticated around the same time and general area as sheep.
👶 The term "kid" for a young goat is older than its usage for human children (which originated in 1800s America).
🐎 Horses were likely domesticated around 6,000 years ago on the Pontic steppe (Ukraine, Russia, Kazakhstan), with evidence found buried with chariots.
🐪 There are two main types: Dromedaries (Arabian camels), domesticated in Arabia/Somalia, and Bactrian camels, originating in Bactria (Afghanistan/Pakistan), used extensively on the Silk Road.
⛰️ Llamas and alpacas are the "cows of the Andes mountains", with llamas ranging from Ecuador to Argentina and alpacas mainly in Southern Peru and Northern Chile.

Other Key Livestock and Products
🐝 Honey bees, valued for honey, wax, and pollination, are thought to have originated in Africa and spread across Eurasia.
📜 The earliest evidence of beekeeping (domestication) is found in Egypt tombs dating back 9,000 years, predating beekeeping suits (invented in the 1500s) by over 7,000 years.
🧵 Silkworms (larval stage of the silkmoth) were domesticated in China roughly 5,000 years ago, with the secret closely guarded until Europeans stole them.

Key Points & Insights
➡️ The choice of diet during scarcity (meat vs. low-quality plants) is cited as a factor leading to the extinction of Australopithecus versus the survival of *Homo sapiens*.
➡️ Chickens were initially valued for entertainment and gambling (cockfighting) for the first 5,000 years of their domestication before being used widely for meat.
➡️ Modern cattle populations are split between taurine cows (Turkey origin) and indicine cows/zebu (Pakistan origin).
➡️ The term "kid" for a human child is an adoption of the older term for a young goat.
