Animal husbandry with more settled communities. The first wild animal to be domesticated was the dog. Half-wild dogs, perhaps starting with young individuals, may have been tolerated as scavengers and killers of vermin, and being naturally pack hunters, were predisposed to become part of the human pack and join in the hunt. Prey animals, sheep, goats, pigs and cattle, were progressively domesticated early in the history of agriculture. Pigs were domesticated in Mesopotamia around 13,000 BC, and sheep followed, some time between 11,000 and 9,000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around
Buru babirusa gestation period lasts 150–157 days. The females have two rows of teats and will give birth to 1–2 piglets weighing 380–1050 grams and measuring 15–20 cm, which they will nurse until the age of 6–8 months. The lifespan is about 24 years. The restricted habitat of the Buru babirusa, with the total area within 20,000 km², and its gradual loss due to logging persuaded the International Union for Conservation of Nature to declare the species as vulnerable. Hunting by the local population is another cause of concern. Whereas it is unpopular among Muslim communities for religious reasons, it is widely
