I've read somewhere that we're the second wave of multi-cellular organisms that evolved on Earth - coming from worms, fish, tetrapods, etc. But there's evidence of an earlier evolution of multi-cellularity, those poor things dying out and leaving very few fossils.
- gpvos 3y agoMaybe you are referring to the Ediacaran period: https://en.wikipedia.org/wiki/Ediacaran_biota https://en.wikipedia.org/wiki/Ediacaran_biota , which happened a bit later. Something like it can have happened before that as well, but that is more the subject of current research like in the featured article.
