> ““Many of the plants that the spider mite targets can release hydrogen cyanide when their tissues are breached. This substance is extraordinarily inimical to life. Exterminators have poisoned rats with it. Whalers added it to their harpoons. The Nazis used it in concentration camps. But the spider mite is impervious. One of its genes can make an enzyme that converts hydrogen cyanide into a harmless chemical. The same gene is present in the caterpillars of various butterflies and moths; they, too, shrug at cyanide. Neither the spider mite nor the caterpillars invented the cyanide-busting gene for themselves, nor did they inherit it from the common ancestor. The gene came from bacteria.””
