Sample answer: Mutations frequently occur when genetic material is replicated, which happens when a virus reproduces. The faster a virus or cell reproduces, the more mutations occur.
Analysis and Interpretations 1. Explain why the homologous structures in Part I are evidence of evolutionary relationships. 2. Explain why analogous structures occur in nature. 3. Using your imagination, what parts of the human body might become vestigial in the next million years. Explain your reasoning. 4.
Learn about the theory of evolution and how it is supported by instances of direct observation, the existence of homologies and fossils, and certain biogeographical patterns.
What are the seven main areas that support evidence of the Theory of Evolution? Fossil Record, Biogeography, Homology and relatedness of form, Vestigial traits, developmental similarities, molecular genetics, observation of evolutionary change.
Proteins evolve through amino acid substitutions (called mutations), which allow species to diverge as their proteins become increasingly different. Species with few amino acid differences share
evolution and evolutionary relationships between organisms. Objective: By observing anatomical and physiological evidence, you will determine their significance in evolutionary theory.
How was the present-day theory of evolution developed? What is adaptation, and how does adaptation relate to natural selection? What are the differences between convergent and divergent evolution, and what are examples of each that support evolution by natural selection?
