Only 3% of mammalian species are socially monogamous, although up to 15% of primate species are. [10] [16] Social monogamy has also been observed in reptiles, fish, and insects. Sexual monogamy is also rare among animals. Many socially monogamous species engage in extra-pair copulations, making them sexually non-monogamous. For example, while ...

In this mating system, female guppies prefer to mate with males with more orange body-coloration. However, outside of a mating context, both sexes prefer animate orange objects, which suggests that preference originally evolved in another context, like foraging.

Animals feature, too, with swans, dogs and horses making appearances as fully-formed or disassembled suggestions of creatures. Engman returned to them because the way they rendered was beautiful ...

[1] Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. [2]
