The Theory of Sexual Selection suggests that traits evolve based on their ability to help individuals of a species secure mates and reproduce. This can lead to the development of exaggerated physical characteristics or behaviors that enhance an individual's mating success. These traits may not always contribute to survival but can increase reproductive success.

What are 4 factor Darwin's used for his theory of evolution?
Darwin's four main factors for his theory of evolution were variation, inheritance, selection, and time. Variation refers to the differences in traits among individuals in a population. Inheritance is the passing on of these traits from parent to offspring. Selection involves the process by which certain traits are favored in a given environment. Time is needed for these processes to occur over generations, leading to the gradual change in populations.
How does the process of natural selection differ from sexual selection in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms that drive evolution, but they differ in how they shape species. Natural selection is based on survival and reproduction, where individuals with advantageous traits are more likely to survive and pass on their genes. Sexual selection, on the other hand, is based on traits that increase an individual's chances of mating, such as elaborate displays or physical characteristics. While natural selection focuses on survival, sexual selection focuses on reproductive success and mate choice.

Why do you think Darwin was at first reluctant to pulish his theory if natural selection?
