Foraminifera: The one-celled predators that shaped our planet (and kept the receipts)

September 2, 2026 · 37 min

Show notes

Single-celled marine organisms called foraminifera may be microscopic, but they've had a massive impact on life on Earth. They also leave behind intricate shells that have become part of a fossil record stretching back more than 500 million years. Today, they're one of the most powerful tools scientists have for reconstructing Earth's past climates, helping us put the current (alarming) state of our warming planet into context.
