I asked a biochemist what life is… and the answer was basically: “If you think you know, you don’t.”
In this video, I talk with Nick Lane about a radical idea: life isn’t really about genes—it’s about energy flow. We go from the dreaded Krebs cycle to the possibility that metabolism came before DNA, and why defining life might be the wrong question altogether.
So here’s what I’m left wondering: if life is just chemistry with a current running through it… where do we draw the line?
