This lesson covers evolution and the theory of natural selection as proposed by Charles Darwin. For AQA GCSE Biology, you need to understand how natural selection works, the evidence for evolution, and how evolution leads to the development of new species. You also need to know about antibiotic-resistant bacteria as a modern example of natural selection in action.
Evolution is the gradual change in the inherited characteristics of a population over many generations. This may result in the formation of new species — a process called speciation.
Evolution occurs through the process of natural selection, first described by Charles Darwin after his voyage on HMS Beagle to the Galapagos Islands in the 1830s.
Charles Darwin (1809-1882) proposed the theory of evolution by natural selection in his book On the Origin of Species (1859).
