The Origin of Multicellular Life: Cell Specialization and Animal Development
Alright, so we've learned a lot about the origin of life. We learned about how the first organic molecules can have formed spontaneously, and how they might have assembled into the first protocell. From there, endosymbiotic theory tells...
