This engaging lesson uses the example of resistant bacteria to describe the principles of natural selection in the evolution of populations. The PowerPoint and accompanying resources have been designed to cover the second part of specification point 4.4 of the AQA A-level Biology specification and also introduces adaptations so that students are prepared for this topic in the upcoming lessons.
President Trump’s error ridden speech about antibiotics is used at the beginning of the lesson to remind students that this is a treatment for bacterial infections and not viruses as he stated. Moving forwards, 2 quick quiz competitions are used to introduce MRSA and then to get the students to recognise that they can use this abbreviation to remind them to use mutation, reproduce, selection (and survive) and allele in their descriptions of evolution through natural selection. The main task of the lesson challenges the students to form a description that explains how this strain of bacteria developed resistance to methicillin to enable them to see the principles of natural selection. This can then be used when describing how the anatomy of the modern-day giraffe has evolved over time. The final part of the lesson introduces adaptations and convergent evolution and also links to the need for modern classification techniques.

Genetic diversity and adaptation (Topic 4.4 AQA A-level Biology)
The 4 lessons included in this mini-bundle are detailed and engaging and have been planned to cover the details of topic 4.4, genetic diversity and adaptation, as laid out in the AQA A-level biology specification. Each lesson is filled with tasks as well as current understanding checks and prior knowledge checks to encourage students to make links between the 4 lessons in this topic as well as across the earlier topics.

Topic 4: Genetic information, variation and relationships between organisms (AQA A-level Biology)
Every one of the lessons included in this bundle is detailed, engaging and fully-resourced, and has been written to cover the content as detailed in topic 4 of the AQA A-level Biology specification. The wide range of activities will maintain engagement whilst supporting the explanations of the content to allow the students to build a deep understanding of genetic information, variation and relationships between organisms. The following 17 lessons covering the 7 sub-topics are included in this bundle: 4.1: DNA, genes and chromosomes * DNA in prokaryotes and eukaryotes * Genes 4.2: DNA and protein synthesis * Genome, proteome and the structure of RNA * Transcription and splicing * Translation 4.3: Genetic diversity can arise as a result of mutation or during meiosis * The genetic code * Gene mutations * Chromosome mutations * Meiosis 4.4: Genetic diversity and adaptation * Genetic diversity * Natural selection * Directional and stabilising selection * Adaptations 4.5: Species and taxonomy * Species and taxonomy 4.6: Biodiversity within a community * Biodiversity within a community * Calculating an index of diversity * The balance between conservation and farming 4.7: Investigating diversity * Investigating diversity * Interpreting mean values and the standard deviation If you would like to sample the quality of the lessons in this bundle, then download the DNA in prokaryotes and eukaryotes, structure of RNA, gene mutations, natural selection and standard deviation lessons as these have been uploaded for free

Topics 4.4 - 4.7 (AQA A-level Biology)
These 9 lessons are highly detailed and are filled with a wide range of tasks that will engage the students whilst covering the following specification points in topics 4.4, 4.5, 4.6 and 4.7 of the AQA A-level Biology specification: 4.4 Genetic diversity as the number of different alleles of genes in a population and a factor enabling natural selection to occur The principles of natural selection in the evolution of populations Directional and stabilising selection Natural selection results in anatomical, physiological or behavioural adaptations 4.5 Two organisms belong to the same species if they are able to produce fertile offspring The taxonomic hierarchy comprising domain, kingdom, phylum, class, order, family, genus and species The use of the binomial name to identify species 4.6 Biodiversity can relate to a range of habitats Species richness Calculating an index of diversity The balance between conservation and farming 4.7 Investigating genetic diversity with, or between species, by comparing observable characteristics or nucleic acids and the structure of proteins Calculating and interpreting the mean and standard deviation If you download the natural selection and standard deviation lessons which have been shared for free then you will be able to see the quality of lessons included in this bundle
