The water-to-land transition is one of the most important and inspiring major transitions used major transitions in evolution in vertebrate evolution. The six most important transitions in the lineage leading to humans are proposed to be: the origin of multicellularity, the origin of two-germ layers and radial symmetry, the origin of three-germ layers and bilateral symmetry, dorsoventral axis inversion, the origin of vertebrates, the.
