So many weird and wonderful aspects of nature and evolutionary biology! “Rhoades [zoologist and chemist] had watched a nearby forest be decimated by an invasion of caterpillars. But then something suddenly changed; the caterpillars began to die. Why? The answer, Rhoades discovered, was that the trees were communicating with one another. Trees that the caterpillars hadn't yet reached were ready: They'd changed the composition of their leaves, turning them into weapons that would poison, and eventually kill, the caterpillars.” #Science is awesome 🧬🦾🚀🤯
