It was not that long ago when the origin of the first vertebrate (fish) was pushed back into the Late Cambrian within the evolutionary time scale.1–3 Then several years ago, two fish-like fossils Myllokunmingia and Haik-ouichthys, with some surprisingly advanced features were discovered from the Early Cambrian in China.4,5 Recently, more than 500 fossils of Haikouichthys have been unearthed in Early Cambrian strata in China.6 These fish somewhat resemble the larva of modern lampreys, a jawless fish (class Agnatha). The upshot of this discovery is to push back the supposed evolution of fish to a very short period during the very beginning of the Cambrian. Ver-tebrates join other existing phyla, as well as many extinct phyla, in the great and...
