Exploring Natural Selection Concepts

The video explores natural selection, starting with an introduction to how traits are determined by genes and how some traits provide survival advantages. It explains artificial selection using dog breeds and selective breeding in agriculture. Natural selection is demonstrated with mice adapting to their environment, and examples include giraffes and bacteria. Darwin's finches illustrate natural selection, and career paths in studying these processes are discussed. An activity to model natural selection is also presented.
