Documenting the broad evolutionary history of animal, or Metazoan, life has been a central goal of biology and paleontology since the early work of Lamarck (1744–1829) and Ernst Haeckel (1834–1919).Numerous competing hypotheses of relationships amongst the 30-some recognized animal phyla have been developed over the past two centuries, most …Buying Freshwater Clams.
