Porcine Survivors

Pigs know how to live off the land. When Hernando de Soto (pictured) began his exploration of Florida in 1539, he brought with him close to 1,000 soldiers, a dozen priests and 15 pigs. By the time that de Soto reached the Mississippi, three years later, he had lost many men. But the pigs had flourished, swelling their ranks to more than 700.
