Cattle & farm animals domesticated

Well establishedStrong fossil, genetic or geological evidence.
Within roughly a thousand years of the first crops, Near Eastern farmers domesticated sheep, goats, pigs and cattle.
See it on the Life map →What happened
Sheep and goats came first, then pigs and cattle. Cattle descend from the aurochs, a huge wild ox; ancient DNA suggests humpless cattle trace to perhaps only about 80 female aurochs in the upper Euphrates valley. Humped zebu cattle were domesticated separately in South Asia. Livestock supplied meat, milk, hides, wool, manure and, later, the pulling power for plows and carts. The last wild aurochs died in Poland in 1627.
Why it matters
Livestock made farming richer and more mobile, selected for new human genes such as adult milk digestion, and passed diseases to people; measles probably evolved from a cattle virus.
The evidence (fossils, genes, rocks)
Bones from early villages show animals shrinking and herds skewed toward culled young males, a sign of management; ancient DNA and milk fats in pottery add detail.
Still debated
How many times and places each animal was domesticated, and how much wild animals bred into domestic herds afterward, are still being worked out.

▸Agriculture begins expanded to include Cattle & farm animals domesticatedWell established
The connection
Settled farming made herding practical: villages could pen animals and feed them crop stubble and surplus grain, while animals provided meat, milk, wool, manure for fields and, later, pulling power for plows. Together they formed a mixed-farming system that spread into Europe, Africa and Asia.
When and how
Sheep and goats in the Taurus and Zagros mountains about 11,000–10,500 years ago; cattle in the upper Euphrates about 10,500 years ago; pigs in Anatolia.
The evidence
Animal bones from village sites show size reduction and culling patterns; milk residues in pottery from about 9,000 years ago show early dairying.
Debates and open questions
Whether animals were domesticated in one core area or several, and how quickly the full mixed-farming package came together.
▸Cattle & farm animals domesticated add methane to Human-caused climate changeWell established
The connection
Cattle, sheep and goats are ruminants: microbes in their multi-chambered stomachs break down grass and release methane, which the animals belch. Over 20 years methane traps about 80 times as much heat as carbon dioxide, though it breaks down within about a decade. Livestock produce roughly a third of human-caused methane; clearing forest for pasture adds carbon dioxide.
When and how
Worldwide, rising with herd numbers, now about 1.5 billion cattle; global atmospheric methane measured systematically since the 1980s.
The evidence
Measurements of animals' breath and of farms, plus atmospheric records showing methane at about 2.6 times preindustrial levels; isotopes help separate livestock from other sources.
Debates and open questions
How much of methane's recent rapid rise comes from livestock versus wetlands, rice paddies and fossil-fuel leaks; feed additives that cut emissions are being tested.
