The monkeys took over the world and the lemur branch of the primate family died out everywhere—other than on Madagascar, which for millions of years the monkeys never reached.

Thanks to astounding advances in twig technology, we arrived in canoes, then boats, and finally airplanes, and once again started to compete for use of the same habitat, only this time with fire and machetes and domesticated animals, with asphalt and concrete.
