Innate behaviors usually involve basic life functions, such as finding food or caring for offspring.

An example is seen in the yellow-rumped honeyguide, a bird whose males defend beehives because the females feed on their wax. The dorsal light reaction is a special case (telotaxis) in which movement occurs at a constant 90° angle to a light source.

​ 5. More commonly, reflex arcs also include an association neuron spliced between the sensory and motor neurons. An example of intersexual selection is when female peacocks choose to mate with the male with the brightest plumage. All of these behaviors involve some sort of communication between population members.

If at any point, the display is performed incorrectly or a proper response is not given, the mating ritual is abandoned and the mating attempt will be unsuccessful. Comparative psychology is an extension of work done in human and behavioral psychology.

Khan Academy is a 501(c)(3) nonprofit organization. The most basic unit of innate behavior is a simple reflex arc.

Thus, there is reciprocity in the behavior. Unlike simple reflexes, FAPs may involve a whole-body response and often require a threshold level of internal readiness (drive). However, these behaviors may not be truly defined as altruism in these cases because the actor is actually increasing its own fitness either directly (through its own offspring) or indirectly (through the inclusive fitness it gains through relatives that share genes with it).

Over time, natural selection can lead to surprisingly intricate and sophisticated behavior such as the dance language of honey bees or the courtship rituals of dance flies.

These are not the same as the communication we associate with language, which has been observed only in humans and perhaps in some species of primates and cetaceans. What is clear, though, is that heritable behaviors that improve the chances of passing on one’s genes or a portion of one’s genes are favored by natural selection and will be retained in future generations as long as those behaviors convey a fitness advantage. One explanation for altruistic-type behaviors is found in the genetics of natural selection. To test this reflex, a doctor taps the tendon below your kneecap with a rubber hammer. But a study of courtship in other dance flies reveals that males use a nuptial gift as a way to divert a female’s aggressive behavior long enough for insemination to occur. Feeding behaviors that maximize energy gain and minimize energy expenditure are called optimal foraging behaviors, and these are favored by natural section. Innate Behaviors: Movement and Migration Innate or instinctual behaviors rely on response to stimuli. Just like physical traits, innate behaviors are phylogenetic adaptations that have an evolutionary history.

Harem mating structures are a type of polygynous system where certain males dominate mating while controlling a territory with resources. The idea that behaviors evolved as a result of the pressures of natural selection is not new. The popular 2005 documentary March of the Penguins followed the 62-mile migration of emperor penguins through Antarctica to bring food back to their breeding site and to their young. A fixed action pattern is a series of movements elicited by a stimulus such that even when the stimulus is removed, the pattern goes on to completion. Over time, natural selection can lead to surprisingly intricate and sophisticated behavior such as the dance language of honey bees or the courtship rituals of dance flies. For example, baby monkeys and apes (including humans) will grasp things with their feet and/or hands. Polygynous mating refers to one male mating with multiple females.

Emperor penguins migrate miles in harsh conditions to bring food back for their young.

Many of these rituals use up considerable energy but result in the selection of the healthiest, strongest, and/or most dominant individuals for mating.
