Genomes Of Deep-Sea Worms Shed Light On The Evolution Of Very Early Animal Ancestors
Deuterostomes are a vast " superphylum " of fauna that include things as various as ocean cucumbers , snake , and people . By analyzing the genomes of inscrutable - ocean invertebrate called acorn worms , researchers hope to clear various characteristics of the most late common root of all deuterostomes – which live more than half a billion years ago . The finding were published inNaturethis week . Three different chemical group of animals make up thedeuterostomes : acorn worm , echinoderms(sea stars , sea urchins , and their relation ) , andchordates(all vertebrates and some invertebrates , such as ocean jet ) ....
