The Evolution of Water: From the First Ocean to the First Cell

Scientists still don't know where Earth's water came from. In June 2026 that debate is more open than ever — new ALMA telescope data links comet 12P/Pons-Brooks to Earth's oceans, a 2024 reanalysis overturned the Rosetta mission's key finding, and a radical new theory suggests Earth made its own water from a magma ocean. But the deeper question isn't where water came from. It's what water actually is — the most anomalous molecule in the universe, with over 70 properties that defy the laws of chemistry, the molecule that built the first membrane, split to create every breath of oxygen you've ever taken, and has been cycling through living organisms for four billion years. You are not a body that contains water. You are water, temporarily organized. Subscribe to Evolution of Life — new episodes every week.    / @theevolutionoflife2026
