  • I-Shou International School IB Biology 5.4 Evolution Assessment Statements 5.4.1 Define evolution. Evolution 5.4.2 Outline the evidence for evolution provided by the fossil record, selective breeding of domesticated animals and homologous structures. Define the following terms: Fossil Selective breeding Domesticated animal Homologous structures Outline how fossils are evidence for evolution. Outline how selective breeding of domesticated animals is evidence of evolution: The pentadactyl limb is an example of a homologous structure. Using the diagram, outline how it is evidence for evolution. (Diagram from: http://warforscience.wordpress.com/2009/12/) 1
  • I-Shou International School IB Biology 5.4.3 State that populations tend to produce more offspring than the environment can support. Define the following terms: Carrying capacity 5.4.4 Explain that the consequence of the potential overproduction of offspring is a struggle for survival. Define the following terms: Competition List 5 ways in which organisms must compete for survival. 1. 2. 4. 3. 5. Explain the consequence of competition for survival. 5.4.5 State that the members of a species show variation. Define the following terms: Variation Species Mutation In a named species, state two variants of a trait. 5.4.6 Explain how sexual reproduction promotes variation in a species. State three ways that sexual reproduction increases variation. 2
  • I-Shou International School IB Biology 1. 2. 3. State how mutations can cause genetic variation. Explain how sexual reproduction promotes variation in a species. 5.4.7 Explain how natural selection leads to evolution. Define the following terms: Natural selection Selective pressure Explain how natural selection can cause a population to change its genetic code over time. 3
  • I-Shou International School IB Biology 5.4.8 Explain two examples of evolution in response to environmental change; one must be antibiotic resistance in bacteria. Use the key terms environmental change, variation, survival, reproduction to annotate this diagram, explaining how antibiotic resistance has evolved. Original population: Source of variation: Environmental change: Effect on population: Selection for: Inheritance: (from i-biology.net) Explain how natural selection led to the evolution of the pepper moth as their environment changed. 4
