The Theory of Evolution and Natural Selection Explained

The video explains the theory of evolution by natural selection, proposed by Charles Darwin. It describes how species evolve from simple life forms over billions of years. The process involves genetic variation within a population, where certain traits provide a survival advantage, leading to natural selection. Over time, these advantageous traits become more common, potentially resulting in new species if populations become too different to interbreed. The video uses examples of insects to illustrate these concepts and concludes with a recap of the key points.
