Year 10 Term 2: Evolution Weeks 6-10 Check Date Revise assumed knowledge: SC4-14LW relates the structure and function of living things to their classification, survival and reproduction □ SC4-15LW explains how new biological evidence changes people’s understanding of the world LW4 The theory of evolution by natural selection explains the diversity of living things and is supported by a range of scientific evidence. (ACSSU185) 5LW4a. describe scientific evidence that present-day organisms have evolved from □ organisms in the past Explain the process of Lamark’s explanation of evolution, and identify its flaws Provide examples of evidence used by Darwin and other scientists during the development of the scientific theory of evolution Activity 2.1.1: Analysing beaks Oxford pg 62 Describe how the theory of plate tectonics can help explain the biogeography of the world Compare artificial and natural selection using examples. Activity 2.1.2: Sexual selection in humans Oxford pg 65 Checkpoint 2.1 Complete questions as homework, a mid-topic test or as a class activity. Use individual student scores to assign support, consolidate or extend checkpoint worksheets from the Teacher obook as required. Oxford pg 71 5LW4c.explain, using examples, how natural selection relates to changes in a population, e.g. in the development of resistance of bacteria to antibiotics and insects to pesticides 5LW4d.outline the roles of genes and environmental factors in the survival of organisms in a population □ □ □ □ □ □ □ □ Identify the four requirements of natural selection □ Natural selection Explores how natural genetic variation within populations provides some individuals with an advantage over others to survive their specific environmental conditions, leading to genetic change in populations over time. □ Activity 2.2.1: Generational change Activity 2.2.2: Selection challenge First hand investigation 2.2.1: Modelling the effects of natural selection Oxford pg 76-79 First-hand investigation: Modelling natural selection Modelling natural selection: Peppered moth interactive http://www.techapps.net/interactives/pepperMoths.swf Questions 2.2.1 Oxford pg 78 Describe how the environmental conditions of a species put pressure on individuals Explain why allele frequencies within a population can change over time Recall that genetic isolation is vital for speciation and list the three main isolating mechanisms □ □ □ □ □ □ □ □ Compare and contrast allopatric and sympatric speciation □ Speciation Discusses the conditions required for and the processes of the evolution of a new species from an existing population. Oxford pg 79-82 □ Evaluate the appropriateness of a scientific model and suggest improvements. Checkpoint 2.2 Complete questions as homework, a mid-topic test or as a class activity. Use individual student scores to assign support, consolidate or extend checkpoint worksheets from the Teacher obook as required. Oxford pg 83 5LW4b. relate the fossil record to the age of the Earth and the time over which life has been evolving Explain how the fossil record is evidence for evolution Reliable evidence Outlines how the sheer volume and similarity of information and data from fossils and historical artificial breeding makes them very reliable evidence for evolution. Oxford pg 84-85 Explain how fossils can be used to estimate the age of the Earth and how this is further evidence in support of evolution Analysing fossils Introduces some of the ways in which fossils are used to demonstrate evolution. Activity 2.3.1: Examining bones Activity 2.3.2: Examining fossils Explain how human-controlled artificial selection of domesticated species is evidence of evolution Explain how human-controlled artificial selection of domesticated species is evidence of evolution Summarise the main processes involved in the formation of fossils Identify that the age of the fossil is the same as the rock layer where it was found, and that the deeper the rock layer, the older it is Describe the importance of transitional fossils and ‘living fossils’ as evidence of evolution Compare and contrast divergent and convergent evolution Explain the differences between analogous and homologous structures Use specific examples to explain how comparative anatomy, embryology and comparative biochemistry can be used as evidence of evolution. Analysing the living Introduces methods of investigating evolution through living species, such as comparative anatomy, embryology and comparative biochemistry.
