Multicellarity in the colonial Volvocales. A Chlamydomonas-like unicellular ancestor might have become multicellular about 200 million years ago, giving rise to the complex multicellular organisms with differentiation of cell functions such as Pleodorina and Volvox. Gonium here studied has primitive 8- or 16-cell body without cellular differentiation. B. Eight-celled body of Gonium pectorale, Eight biflagellate cells of the same size are arranged in
