DNA Conserved in Diverse Animals Since the Precambrian Controls Genes for Embryonic Development.

“Here, we report 25 regulatory DNA segments conserved across bilaterian animals, of which 7 are also conserved in cnidaria (coral and sea anemone).” “On the other hand, no conserved segments were found in fly (Drosophila melanogaster), roundworm (Caenorhabditis elegans), or leech (Helobdella robusta).”
