Thanks to Brilliant for supporting this week of SciShow! Go to Brilliant.org/SciShow to learn more. [ intro ] There’s a lot written about how early animals transitioned from living in water to living on land. But you rarely hear how /plants/ did it. That’s kind of a shame, because plants reached land first, and they conquered the planet way faster ... Read More
