These benefits include but are not limited to increased territory quality, increased parental care, and protection from predators. There is much support for maintenance of mate choice by direct benefits [5] and this approach offers the least controversial model to explain discriminate mating. [6]
Female guppies tend to exhibit mate-choice copying by employing visual observation of a demonstrator female's mate choice.. Mate-choice copying requires a highly developed form of social recognition by which the observer (i.e. copier) female recognizes the demonstrator (i.e. chooser) female when mating with a target male and later recognizes the target male to mate with it.

Human mate choice, an aspect of sexual selection in humans, depends on a variety of factors, such as ecology, demography, access to resources, rank/social standing, genes, and parasite stress. While there are a few common mating systems seen among humans, the amount of variation in mating strategies is relatively large.
Sexual selection creates colourful differences between sexes in Goldie's bird-of-paradise.Male above; female below. Painting by John Gerrard Keulemans.. Sexual selection is a mechanism of evolution in which members of one 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 ...
European pied flycatcher Ronald Fisher in 1912. The sexy son hypothesis in evolutionary biology and sexual selection, proposed by Patrick J. Weatherhead and Raleigh J. Robertson of Queen's University in Kingston, Ontario in 1979, [1] states that a female's ideal mate choice among potential mates is one whose genes will produce males with the best chance of reproductive success.
Sexual selection is a biological way one sex chooses a mate for the best reproductive success. Most compete with others of the same sex for the best mate to contribute their genome for future generations. This has shaped human evolution for many years, but reasons why humans choose their mates are not fully understood.
The number of childfree women is at a record high: 48 percent of women between the ages of 18 and 44 don’t have kids, according to 2014 Census numbers. The Huffington Post and YouGov asked 124 women why they choose to be childfree.
On the other hand, there was no evidence of MHC-based mate choice in the same study of 200 couples from South Amerindian tribes. [23] Other studies have approached mate choice based on odor preference. In one study done by Wedekind et al., women were asked to smell male axillary odors collected on T-shirts worn by different males.
