"I bet that yeast, having once been multicellular, never lost it completely," says Neil Blackstone, an evolutionary biologist at Northern Illinois University in DeKalb. "I don't think if you took something that had never been multicellular you would get it so quickly." That gives me slight hope to the credence of my theory ^_^ as the "first movers" in that the first single cellular life which grouped into multicellularity life would experience evolution that allowed made them more friendly to multicellular life, so that even when split up they have systems that encourage reunification. As a whole however it does makes my mini theory less plausible, thanks for the help in Changing my Mind :)
