Solarion Discovery: New Evidence Reshapes the Timeline of Eukaryotic Life Origin
Understand how the accidental discovery of a rare microbe, Solarion, provides direct genetic evidence linking ancient Archaea to the emergence of all complex life on Earth. This organism holds a missing genetic toolkit that bridges the gap between single-celled prokaryotes and complex eukaryotes, rewriting parts of our evolutionary past.
Short Summary
- Discover Solarion arienae, a previously unknown eukaryote that forms a new supergroup called Theparia among ancient single-celled organisms.
- Identify the persistence of the bacterial SecA gene within Solarion's mitochondria.
- Establish that the Last Eukaryotic Common Ancestor (LECA) likely possessed a much more "bacterial" mitochondrion than current models suggest.
This discussion traces the evolutionary path from simple prokaryotes to complex eukaryotes, highlighting the significance of the Asgard archaea. We then examine how Solarion, found by accident, provides a living snapshot of the immediate ancestor of all complex life, revealing the molecular toolkit retained from the initial symbiotic merger.

This makes me wonder how many ancient persistence strategies never made it past the early chaos. Solarion feels like a living fossil from a forgotten evolutionary experiment reminder that life didn’t take a single path, it sampled a whole menu before settling into what we call cells today.
Mitochondria is the Powerhouse of the Cell. just like... Anton is the Powerhouse of the Cutting edge science communication.
I recognized the names from the paper: Ivan Čepička taught me protistology in undergrad! And the rest of the people also either work at my uni or at the institute I currently do my master's project at! So proud of them and their amazing research.
Wonderful as always Anton. Thank you. ☺😸👍
This transitional period in complex life is so fascinating, and I'm so glad to be alive during lots of present and future discoveries about it. Thanks Anton!
Just passing by to say I just watched my YT 2025 recap and I'm proud to say I'm in your top 0.2% of viewers! I love your work, I watch every daily video of yours just before bedtime. You're doing fantastic work, keep it up :)
This is the only channel I don't skip the ads just so they get full ad revenue
this makes me so proud of my country for discovering this 🇨🇿🇨🇿🇨🇿
Looks like a small solar system with orbital planets :)
What a name for organelles - celestiosomes, heavenly bodies.
