In the fifth “We Know So Little” post at Pidgeonholes—my recurring series about being awed by the world around us—I explore the Osage orange and other evolutionary anachronisms, these things lost in time that yet persevere:
A thing evolves, typically adjacent to other things—coevolution. So a plant, for example, might evolve its fruit to be eaten a certain way by a certain species in order to ensure its seeds are properly dispersed. But in the case of evolutionary anachronism, one of the parts of this relationship dies off. And yet, the plant’s relic behavior remains, visible to us, pumping away like a still-warm, body-less heart.
