Insights into cephalochordate genome and gene evolution from the early-diverging amphioxus Asymmetron lucayanum

Proceedings of the National Academy of Sciences, Volume 123, Number 12, March 2026.
SignificanceCephalochordates (amphioxus or lancelets) are chordates of invertebrates that diverged first in the chordate lineage leading to vertebrates. Thus, their genomes can help reveal the genetic basis of the evolutionary transition of a…
