Chimpanzees could have rafted to Bioko on an entire floating island

Thanks to Terry Turner and Bernard Harper for these tips about rafting monkeys. Upright trees and turf with monkeys and other animals have been observed floating down rivers and into the sea. This is how the founding Green iguanas may have come to the Galapagos, and the founding Chimpanzees may have come to Bioko, when they were barren volcanic islands with no forest foods.
