James Brady+FollowEarth’s OG Life Form Wasn’t Alone?!Scientists just pushed back the origin of life on Earth by 200 million years! Turns out, LUCA—the last universal common ancestor—was living it up 4.2 billion years ago, and it wasn’t as solo as we thought. This ancient microbe had a big genome, a viral defense system, and maybe even hung out in both deep-sea vents and surface waters. Basically, all life on Earth can trace its roots back to this microbial legend. Mind = blown! #Science #ScienceNews #OriginsOfLife00Share
