-Since their origin nearly 770 million years ago, animals have undergone extensive diversification and evolved dramatically different body plans. Describe some of the major steps in animal evolution and the body plans associated with different levels of animal complexity. (Include examples of animal that exhibit the body plans you describe.)
-The arthropods, including insects, are the most successful animal lineage. Discuss aspects of the arthropod body that seem to have led to such success. What aspects of insect biology and morphology make them the most successful group within the arthropod lineage?
-Echinoderms have been a successful lineage since their appearance in the Cambrian period, though as adults are arranged differently from many of their close relatives. Describe ways in which echinoderms differ from other deuterostome animals?
-Filtering food from water is a common feeding strategy seen in many different animal lineages. Compare and contrast filter feeding strategies (feeding structures, means of collecting food, etc.) of animals from three different phyla.
-One feature of plants that we talked a lot about is their life cycle that includes alternation of generations. What is alternation of generations? How did this basic feature of the life cycle change as plant diversified and became more successful in the terrestrial environment?
-One could argue that eukaryotic life is dependent on prokaryotic life and always has been. In what ways can the origin and success of eukaryotic life forms be attributed to the actions and capabilities of prokaryotic life?
In your own words please no citations and copying from the internet please, double spaced and up to 3/4 to 1 page, please get straight to the point and less on background
