Abstract

Lancelets, or amphioxus, are small worm-like marine animals that share key anatomical and developmental features with vertebrates and tunicates. Together, the vertebrates, tunicates and lancelets constitute the Chordates, having had a common ancestor that lived about 550 million years ago. The lancelets are the modern survivors of ancient chordates.
