Document Summary

Complex life started with the evolution of eukaryotes. Cells can come together : colonial species. Cells can stay together : true multicellularity. A range of adaptions are required for multicellularity. Multicellularity evolved frequently in very different organisms. They need to specialise, so that not all cells do the same thing. For all of the above to happen cells should not reject each other. Natural selection too cares only about what works. Hence, irrespective of how cells come together, if the result is a functional unit then selection can act on this (convergent evolution)
