Bees are old. Prehistoric old. Their fossilized ancestors have been discovered in droplets of amber resin dating between 75 and 95 million years ago. Having evolved from wasps, they arrived during the late Cretaceous period, that moment in time when a 6-mile-wide asteroid ended its fiery journey across the cosmos with a splashdown in the Gulf of Mexico. The collision ignited the last great extinction and doomed 70% of the world’s species.
