Conflicting phylogenetic signals at the base of the metazoan tree.

Evolution & development - 1 Jan 2000

Rokas Antonis, King Nicole, Finnerty John, Carroll Sean B

Abstract excerpt

A phylogenetic framework is essential for under-standing the origin and evolution of metazoan development. Despite a number of recent molecular studies and a rich fossil record of sponges and cnidarians, the evolutionary relationships of the early branching metazoan groups to each other and to a putative outgroup, the choanoflagellates, remain uncertain. This situation may be the result of the limited amount of...
