Chinese and American scientists review early evolution of eukaryotic multicellularity

The ascent of multi-celled life or multicellularity is a major evolutionary transition. Multicellularity evolved independently at least 25 times among eukaryotes, and complex multicellularity (characterized by intercellular communication and tissue differentiation controlled by regulatory gene networks) occurs in a handful of eukaryotic groups including animals.
