The paper traces the fate of tail bud cells in amphioxus, showing they generate neural tube, notochord, and somites, supporting the hypothesis that ancestral chordates had multipotent tail bud cells.

The paper identifies a tripartite neural plate border in ascidian embryos, suggesting it was present in the last common ancestor of vertebrates and tunicates.

The paper identifies ascidian embryonic cells with properties similar to vertebrate neural-crest cells and neuromesodermal progenitors, suggesting ancestral cell types in the last common ancestor of ascidians and vertebrates.
