 The Biodiversity, Evolution, and Disease section of Biology specifications covers the variety of life on Earth, how it is classified, and the importance of maintaining biodiversity. It includes methods of sampling and measuring biodiversity, adaptations of organisms, and the principles of natural selection and evolution. The section also explores the causes and prevention of disease, the immune response, and the development of immunity. Additionally, it examines the use of antibiotics and the impact of antibiotic resistance, as well as strategies for disease control and global health concerns. 

 The Classification & Evolution section of Biology specifications covers the principles of taxonomy and how organisms are classified into domains and kingdoms based on their characteristics. It explores different classification systems, such as the three-domain system, and the use of molecular evidence in classification. The section also examines the process of evolution through natural selection, including the role of genetic variation, adaptation, and speciation. Additionally, it looks at the evidence for evolution, including fossil records and molecular comparisons, as well as the impact of evolution on biodiversity and classification.
