Primordial Weather Report: Hot, Acidic

POSTED BY: BETUL KACAR
 

Ancestral Sequence Reconstruction methodology allows us to create ancient life in the laboratory. It’s a neat tool, that combines synthetic biology with bioinformatics in a very unique way. We can analyse and listen to the story of these ancient molecules and then use these stories to understand conditions that hosted ancient life.

Here is a recent ASR study. By resurrecting ancient thioredoxin biomolecules, researchers show that ancient life was not only hot, but was acidic too. So here goes our first primordial weather report showing that if a time machine that allows us to go all the way bak to primordial life is ever invented, it would be wise to pack along a acid-resistant warm coat!
