This fully-resourced lesson describes how natural selection results in species with anatomical, behavioural and physiological adaptations. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the fourth part of point 4.4 of the AQA A-level Biology specification and make continual links to the earlier parts of this topic including evolution and genetics.
A quick quiz competition at the start of the lesson introduces the different types of adaptation and a series of tasks are used to ensure that the students can distinguish between anatomical, behavioural and physiological adaptations. The Marram grass is used to test their understanding further, before a step by step guide describes how the lignified cells prevent a loss of turgidity. Moving forwards, the students are challenged to explain how the other adaptations of this grass help it to survive in its environment. A series of exam-style questions on the Mangrove family will challenge them to make links to other topics such as osmosis and the mark schemes are displayed to allow them to assess their understanding. The final part of the lesson focuses on the adaptations of the anteater but this time links are made to the upcoming topic of taxonomy so that students are prepared for this lesson on species and classification hierarchy.

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 * 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 7 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 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
