Abstract: | The phylum to which humans belong, Chordata, takes its name from one of the major shared derived features of the group, the
notochord. All chordates have a notochord, at least during embryogenesis, and there is little doubt about notochord homology
at the morphological level. A study in BMC Evolutionary Biology now shows that there is greater variability in the molecular genetics underlying notochord development than previously appreciated. |
