• Understand the evolutionary implications of gene duplication
• Understand the significance of highly conserved genes in speciation and diversity
• Understand the role of stop codons in imparting new traits
• Explain the morphological diversity of fish jaws
• Understand how ancestral genes develop new functions over time
