variation within species? 4.4.4.3 Evidence for evolution comes from the study of fossils that show how much or how little different organisms have changed as life developed on Earth. Evolution of bacteria can be observed happening in a much shorter time because they reproduce so fast. Bacteria that cause disease evolve by natural selection when exposed to antibiotics; this gives rise to a resistant strain. Describe the evidence for the theory of evolution by natural selection. Define the term ‘fossil’. Explain what we should do to slow down the rate of development of resistant strains of bacteria. Describe the impact of antibiotic resistance 1 Discuss the evidence we have to support Darwin’s theory and present in a suitable format. Observe fossils or pictures of fossils eg images of a range of trilobites. What factors may have caused the changes visible in the form of the fossils? How much do these observations contribute to the theory of evolution? Discuss how fossils provide evidence for evolution. Students design a presentation for primary schools to show why it is important not to use antibiotics routinely and how they can prevent the spread of infection. Explain how bacteria can become resistant to antibiotics. Explain how antibiotic resistance has impacted on Students produce tables of results from graphs which show antibiotic resistance in bacteria and the impact of antibiotic restriction on resistance. Why did Fleming, Forey and Chain share the 1945 Nobel Prize for Medicine? Use data from antibiotic timeline to plot a graph of year of introduction vs year resistance developed. Calculate the average time between introduction and resistance developing.
