The survival and reproduction of insects that are resistant to Bt toxins is a clear example of natural selection. In this case, the selection pressure (the presence of the Bt toxin) is favoring the survival and reproduction of the resistant insects, leading to a shift in the frequencies of the resistant allele in the population. This is a well-known example of evolution in action, and it highlights the powerful role that natural selection can play in shaping the genetic makeup of populations over time.
