Sexual selection
Sexual selection is a mechanism of evolution where individuals with certain traits are more likely to attract mates and reproduce. These traits can include physical characteristics, like bright plumage in birds or larger antlers in deer, as well as behaviors, like elaborate courtship displays. This process can lead to dramatic differences between the sexes (sexual dimorphism) and can enhance the chances of passing on genes. Essentially, it's a way for nature to favor traits that improve mating success, sometimes even at the cost of survival.

Sexual selection is a natural process where certain traits increase an individual's chances of attracting a mate and reproducing. It can lead to the development of features like elaborate plumage in birds or impressive antlers in deer. These traits may not necessarily enhance survival but play a crucial role in mate choice. For example, a peacock's vibrant feathers can attract peahens, while a strong male may fend off rivals. Sexual selection explains how certain characteristics evolve over generations, driven by preferences for attractiveness or dominance, shaping the diversity of life and behaviors in many species.
