In evolutionary psychology, people often speak of the four Fs which are said to be the four basic and most primal drives (motivations or instincts) that animals (including humans) are evolutionarily adapted to have, follow, and achieve: fighting, fleeing, feeding and mating (a more polite synonym of the word "fucking").

Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements.The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus.
The female fruit bat performs fellatio on a male fruit bat during copulation to increase overall copulation time. Although fellatio is a common human foreplay activity, it is less common among non-human animal species. At this point, it is unclear exactly what neurological forces motivate fruit bats to engage in fellatio during sex, although ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
Under natural conditions, sows will leave the herd and travel up to 6.5 km (4.0 mi) [6] a day prior to parturition in order to find the appropriate spot for a nest. [8] The sows will use their forelimbs and snouts in order to create excavated depressions within the ground and to gather/transport nesting materials. [9]
Sonograms of female copulatory vocalizations of a human female (top), female baboon (middle), and female gibbon (bottom), [19] with time being plotted on the x-axis and the pitch being represented on the y-axis. In non-human primates, copulatory vocalizations begin towards the end of the copulatory act or even after copulation. [2]

Vertebrate maternal behavior is a form of parental care that is specifically given to young animals by their mother in order to ensure the survival of the young. [1] Parental care is a form of altruism, which means that the behaviors involved often require a sacrifice that could put their own survival at risk. [1]
