====== Natural Selection and Evolution Demonstrations ===== Natural selection is the process by which traits that improve survival and reproduction become more common in populations over time, leading to evolution. This category explains how variation, competition, and inheritance shape the diversity of life. Studying natural selection and evolution provides a framework for understanding both the history of life and the adaptation of species to their environments.\\ ---- struct table ---- schema: demo cols: page, materials, difficulty, safety, summary header: "Demonstration", "Materials", "Difficulty", "Safety", "Summary" filter: categories~Natural Selection and Evolution filter: page~demonstrations:% sort: title csv: 0 ---- **Materials**\\ ★☆☆ Easy to get from supermarket or hardware store\\ ★★☆ Available in most school laboratories or specialist stores\\ ★★★ Requires materials not commonly found in school laboratories\\ **Difficulty**\\ ★☆☆ Can be easily done by most teenagers\\ ★★☆ Available in most school laboratories or specialist stores\\ ★★★ Requires a more experienced teacher\\ **Safety**\\ ★☆☆ Minimal safety procedures required\\ ★★☆ Some safety precautions required to perform safely\\ ★★★ Only to be attempted with adequate safety procedures and trained staff\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\
