Final answer:
Pigs were first thought to be domesticated in the Middle East region, part of the Fertile Crescent, around 11,000 years ago, during the Neolithic Revolution.
Step-by-step explanation:
The country that is thought to have domesticated the pig first is considered to be in the ancient Near East region, corresponding to today's Middle East. This area is part of what is known as the Fertile Crescent, where the pigs, along with other livestock like goats, sheep, and cattle, were domesticated as part of the Neolithic Revolution. This transition from foraging to farming, including animal domestication, began around 11,000 years ago. Moreover, farming spread from the Middle East to regions such as southern Germany and Holland by around 6,000 to 7,000 years ago, where evidence shows that pigs were also being kept.
It is also important to note that other regions around the world have a history of domesticating animals independently. For example, in the Andean region of South America, the domestication of certain animals like llamas and guinea pigs was undertaken, but this occurred at different timelines compared to the Middle East.
