Why Life Chose Oxygen

Hey guys! We’re now live on Spotify🎧

Take a breath. About a fifth of it is a gas that once poisoned most life on Earth and still feeds every fire that has ever burned. You are made of exactly the fuel it loves, yet it never sets you alight. Of everything chemistry offers, why did life build itself on this one?
Tonight we follow it from a minister's burning lens in 1774 to a rusting ancient ocean and a pale blue liquid that refuses to fall through a magnet, circling a question that took centuries to answer.
Get comfortable and let this slow walk through the strange physics of the air you breathe keep you company tonight. Subscribe to Sundown Science if you enjoy the long way around the universe.

cellulose is a sugar... it is a carbohydrate just like glucose
but simply of a different order of complexity than a simple sugar such as fructose or glucose
and it is not merely because wood is made out of carbon, as you seem to say
