Ep 10 - Inside the cell city

EP 12 - From one to many (multicellularity)

Any thoughts? Text me! [https://www.buzzsprout.com/2571292/fan_mail/new] For three billion years, life went solo. Then one day, some cells forgot to separate after dividing — and that tiny accident changed the history of Earth. In Episode 12 of From Cells to Us… How?!, we explore the rise of multicellular life: the first cells that learned to cooperate, the evolutionary battle against cheating cells (aka cancer), and how trillions of individual cells eventually became… you. Because multicellularity didn’t just make life bigger. It made complexity possible.

Ep 11 - Sexual Reproduction

Any thoughts? Text me! [https://www.buzzsprout.com/2571292/fan_mail/new] Sex Didn’t Evolve to Make Babies What if I told you sex didn’t evolve to reproduce? A billion years ago, single-celled organisms were already doing something that looks a lot like sex — and it had nothing to do with babies. No embryos. No development. No families. Just two cells, briefly merging… shuffling their DNA… and separating again. So why would evolution invent something so inefficient? Why give up cloning — the fastest, simplest way to survive — for something slower, riskier, and more complicated? The answer involves parasites, broken DNA, and a billion-year-old survival strategy that’s still running inside your body right now.

Ep 10 - Inside the cell city

Any thoughts? Text me! [https://www.buzzsprout.com/2571292/fan_mail/new] Episode 10: Inside the Cell City 🧬 What if your cells weren’t just blobs… but fully functioning cities? In this episode, we take a tour inside the eukaryotic cell — where proteins are built, packaged, shipped, and even recycled. From the rough ER and Golgi apparatus to lysosomes and motor proteins, every part of the cell has a job. And none of it was planned. Every organelle exists because it solved a problem — one solution leading to the next, turning simple cells into something incredibly complex. 🎧 Next: Sexual reproduction — one of the strangest innovations in the history of life. 🧠 Take the quiz (ep 1-9) - fromcellstous.com   🧠 Take the quiz (ep 10) - ep10quiz.fromcellstous.com [http://ep10quiz.fromcellstous.com/] 📩 More + sources: https://open.substack.com/pub/fromcellstoushow [https://open.substack.com/pub/fromcellstoushow]

Ep 9 - The cell that ate the sun (photosynthesis)

Any thoughts? Text me! [https://www.buzzsprout.com/2571292/fan_mail/new] A cell eats another cell… again. But this time? It doesn’t just get energy — it gets the ability to make food from sunlight. In this episode, we dive into chloroplasts, photosynthesis, and the moment life figured out how to turn sunlight and air into sugar. Plants stop hunting. Animals don’t. And every calorie you’ve ever eaten? It all traces back to this one ancient accident.

Ep 8 - Rise of the Eukaryote

Any thoughts? Text me! [https://www.buzzsprout.com/2571292/fan_mail/new] Episode 8: The Rise of Eukaryotes — The Cell That Changed Everything | The Mitochondria and the Nucleus  How did life become complex? In this episode, we explore how eukaryotic cells evolved from simple prokaryotes through one of the most important events in biology: endosymbiosis — when one cell engulfed another and kept it alive. Learn how mitochondria originated from bacteria, why more energy allowed complex life to evolve, and how this single evolutionary partnership led to animals, plants, and humans. We also break down the difference between prokaryotic vs eukaryotic cells, the debated origin of the nucleus, and why evolution isn’t just “survival of the fittest” — it’s also about collaboration.
