Analysis of animal genes found evidence that, after humans had diverged from other apes, interspecies mating nonetheless occurred regularly enough to change certain genes in the new gene pool. [163] Researchers found that the X chromosomes of humans and chimps may have diverged around 1.2 million years after the other chromosomes.
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [1] [2] This is an aspect of mating.
The articles in this category are primarily about mating in animals, although a few of them (such as mating in yeast and mating in fungi) are about other types of organisms. Wikimedia Commons has media related to Mating .
Photographers have captured two male humpback whales having sex, in what experts say is the first time the species has been documented exhibiting sexual activity of any kind.
For animals, mating strategies include random mating, disassortative mating, assortative mating, or a mating pool. In some birds, it includes behaviors such as nest-building and feeding offspring. The human practice of mating and artificially inseminating domesticated animals is part of animal husbandry.
Sexual coercion among animals is the use of violence, threats, harassment, and other tactics to help them forcefully copulate. [1] Such behavior has been compared to sexual assault, including rape, among humans. [2] In nature, males and females usually differ in reproductive fitness optima. [3]
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. [4]
Given that the utilization of alternative mating strategies has been shown to fluctuate over time, it has been suggested that frequency or negative frequency-dependent selection is the mechanism through which alternative mating strategies are maintained in animal populations.
