How many species are in each of the above groups? Which one has the most species? When did the first vertebrates appear, and when did they first live on land? Where do we find the earliest fossils of vertebrates, and where do we find the earliest fossils of terrestrial (land-living) vertebrates? What are the following and how are they related to humans: Pongo, Gorilla, Pan, Sahelanthropus, Ardipithecus, Australopithecus, Homo erectus, and Homo neanderthalensis? Which of these is our closest living relative? What are some of the traits that these organisms share with us? When and where did each of the extinct forms above live? What does this tell us about when our lineage split from the most recent ancestor we share with our closest living relative?Within the subphylum Urochordata is a group called the appendicularians (or larvaceans; class Appendicularia). This relatively obscure group of organisms plays an important role in the global carbon cycle and other biogeochemical processes in the ocean.
