Further Investigations: Evidence of Common Ancestry and Diversity

  1. Public awareness about invertebrates is often limited. Brainstorm ideas to increase public knowledge and appreciation for invertebrates. Emphasize their importance to humans as well as their diversity. Present your ideas to the class.
  2. The phylogenetic tree of major phyla presented in Fig. 3.4 illustrates the evolutionary relationships between different phyla within kingdom Animalia. Use library and Internet resources to investigate how scientists build such phylogenetic trees. How do phylogenetic trees improve our understanding of the evolution of animals? How has our understanding of animal evolution changed with recent technological advances?
