Many plants contain poisons, which cause problems for leaf-eating monkeys like the colobus. But monkeys are problem solvers. Some red colobus in Zanzibar have learned that the charcoal left by local people's fires makes a perfect antidote to the toxins. The monkeys are used to seeing the locals burn charcoal for fuel. Somewhere along the way, the colobus adopted it for their own medicinal use. This means that they can now even eat introduced plants, like the Indian almond.
