The theory of evolution by natural selection, proposed by Charles Darwin and Alfred Russel Wallace, transformed the way we understand the natural world. Through careful observations, made over many years, they each realised that animals and plants that are particularly well suited to their environment are the most likely to survive, and so pass these characteristics on to the next generation. Gradually, over many generations, these characteristics – such as long necks, warm fur, being able to see well in the dark etc – become more common in a population, and a species changes over time.
