Evolutionary tree of volvocine algae. An evolutionary tree of volvocine algae based on the nucleotide sequences of five chloroplast genes. This phylogenetic analysis indicates that multicellularity evolved only once in this group. There are two fundamentally different sequences through which embryos of the genus Volvox turn right-side out: type A and type B inversion. The type of inversion is indicated for all species of the genus Volvox.
