Hundreds of millions of years ago, dragonflies with wingspans exceeding two feet ruled prehistoric skies — not through some lost evolutionary miracle, but because the atmosphere itself permitted their existence. When oxygen comprised roughly 35 percent of ancient air, the fundamental physics of insect respiration allowed bodies of extraordinary scale; as that abundance faded, so too did the giants. Their story is less about extinction than about the quiet, absolute authority that planetary chemistry holds over the boundaries of life.
