1. Sexual selection

   Sexual selection is a mode of natural selection in which members of one biological sex choose mates of the other sex to mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual selection). These two forms of selection mean that some individuals have greater reproductive success than others within a population, for example because they are more attractive or prefer more attractive partners to produce offspring. Successful males benefit from frequent mating and monopolizing access to one or more fertile females. Females can maximise the return on the energy they invest in reproduction by selecting and mating with the best males. The concept was first articulated by Charles Darwin who wrote of a "second agency" other than natural selection, in which competition between mate candidates could lead to speciation. The theory was given a mathematical basis by Ronald Fisher in the early 20th century. Sexual selection can lead males to extreme efforts to demonstrate their fitness to be chosen by females, producing sexual dimorphism in secondary sexual characteristics, such as the ornate plumage of birds-of-paradise and peafowl, or the antlers of deer. This is caused by a positive feedback mechanism known as a Fisherian runaway, where the passing-on of the desire for a trait in one sex is as important as having the trait in the other sex in producing the runaway effect. Although the sexy son hypothesis indicates that females would prefer male offspring, Fisher's principle explains why the sex ratio is most often 1:1. Sexual selection is widely distributed in the animal kingdom, and is also found in plants and fungi.

1. Sexual selection

   Sexual selection is a mode of natural selection in which some individuals outreproduce others of a population because they are better at securing mates. The concept was introduced by Charles Darwin in his 1859 book On the Origin of Species, is a significant element of his theory of natural selection. The sexual form of selection His sexual selection examples include ornate peacock feathers, birds of Paradise, the antlers of stag, and the manes of lions. Darwin greatly expands his initial three-page treatment of Sexual Selection in the 1871 book The Descent of Man and Selection in Relation to Sex. This 900-page, two-volume work includes 70 pages on sexual selection in human evolution, and 500 pages on sexual selection in other animals. In summary, while natural selection results from the struggle to survive, sexual selection emerges from the struggle to reproduce.

2. Wang Min:

   The well-preserved tail feathers in this new fossil bird provide great new information about how sexual selection has shaped the avian tail from their earliest stage, the complexity we see in Yuanchuavis's feathers is related to one of the reasons we hypothesize why living birds are so incredibly diverse, because they can separate themselves into different species just by differences in plumage and differences in song.
