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?
Which group of Chordata maintains the vertebrate characteristics throughout life?
Cephalochordata
Urochordata
Tigers
Chondrichthyes
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. Use library and Internet resources to research the natural history of these unique invertebrate chordates. What do they eat? How do they capture food?
