How do natural selection and sexual selection differ in their roles in shaping the evolution of species?

Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
