Did red algae descend from green algae?
Plant Evolution
TAKE-AWAY: Red and green algae diverged 1.5 billion years ago, shaping marine ecosystems. Green algae later evolved into land plants around 475 million years ago, transforming Earth’s surface and atmosphere. Fun fact: blue-green algae aren’t algae—they’re photosynthetic bacteria!
Quote of the week
2-Philosophy
Quote
“Identity is easy — it’s me, whatever that is.”
Identity
TAKE-AWAY: Identity feels solid, but it shifts with every stage of life. You are not fixed; you’re evolving. This line reminds us that “me” isn’t a static definition but an ongoing story. Knowing that frees you to grow, question, and become something better than yesterday’s version.
