USA HISTORY

Detailed explanation-1: -Wild pigs (also known as wild hogs, wild boar, or feral swine) are an Old World species and are not native to the Americas. The first wild pigs in the United States originated solely from domestic stock brought to North America by early European explorers and settlers.

Detailed explanation-2: -Archaeological evidence suggests that domestic pigs arrived in Europe about 8, 500 years ago with farmers from the Near East. But, confusingly, the DNA of modern European pigs is derived from European wild boar and not Near Eastern animals.

Detailed explanation-3: -Along with the people, plants and animals of the Old World came their diseases. The pigs aboard Columbus’ ships in 1493 immediately spread swine flu, which sickened Columbus and other Europeans and proved deadly to the native Taino population on Hispaniola, who had no prior exposure to the virus.

Detailed explanation-4: -The pig dates back 40 million years to fossils, which indicate that wild pig-like animals roamed forests and swamps in Europe and Asia. By 4900 B.C. pigs were domesticated in China, and were being raised in Europe by 1500 B.C.

Detailed explanation-5: -Based on that thinking, researchers imagined that about 9000 years ago, humans corralled a few wild boars and-by separating them from their fellows and breeding them for favorable traits like tameness, size, and meatiness-they developed the domesticated oinkers that we see all over the world today.
