Natural Selection Examples

This resource introduces natural selection and three key examples of rapid changes in species brought about by evolution: bacterial resistance to antibiotics, pesticide resistance in insects, and the peppered moth before, during and after the industrial revolution. I use the first slide to introduce the process of natural selection. I then use an incredibly useful resource, available for download from TES on “sticky dogs”, which I get the class to evaluate. I then introduce the peppered moth example, before getting the students to complete the 6 mark past paper question to time. We go through the mark scheme to this question together before I introduce bacterial resistance and pesticide resistance. The students then complete the tasks set on the final slide.
