Genomic Link Found between All Deuterostomes
Genomic similarities had been discovered separately among all chordates and all ambulacrarians, but a genomic connection between the two groups remained elusive. The researchers found a region of the Hox cluster in two acorn worm species, Saccoglossus kowalevskii and Pytchodera flava, that follows a nearly identical genomic order in their chordate relative, Brachinostoma floridae. The conserved area in the genome of these two worms provides the first evolutionary link between hemichordates and chordates, and, as a result, all deuterostomes.
