Weapon

In biology, a weapon is a trait that is used by animals to compete with other individuals for resources.[3] Most commonly, the term refers to structures that males to fight other males off for access to mates.[4] A mate is won in battle either by a male chasing off a fellow competitor or killing it off, usually leaving the victor as the only option for the female to reproduce with.[5] However, because stronger organisms, whether mentally or physically, are usually favored in combat, this also leads to the evolution of stronger organisms in species that use combat as a way to secure mates, via intrasexual selection.[6] Examples of weapons include: antlers, horns, and ossicones.

Since Darwin's publication The Descent of Man, extensive research has been done on the presence of agonistic behavior and the usage of animal weaponry by different species.[7] Weaponry displays in animals have been found to increase their likelihood of survival in different ways, such as when interacting with other individuals or trying to find another mate.[8] Weaponry in animals consist of any specialized morphology that is present within an organisms to aid in its advantage against rivals.[7] These specialized structures have different functions for animals such as competition for resources and mates, protection from predators, and much more. With the evolution of weaponry, many hypotheses have been produced by researchers to possibly explain the mechanisms behind its rapid diversification within species.[9] 

Occurrence

The horn-like projections of a chameleon are used to fight other males on tree trunks.

Weapons are common among many genera of animals. Among vertebrates, they are most often found in mammals and fish, and are also known to occur in reptiles, though far less commonly in that class. Many species of dinosaur, an extinct clade of vertebrates, also possessed weapons. Arthropods, such as arachnids and crabs, also have species that wield weapons, and they are extraordinarily widespread among insects. [10]

In mammals, weapons are common and take a number of diverse forms. They are most common among the ungulates.[10] Antlers, complex and unique weapons that are an extension of an animal's skull, are found only among male deer, ungulates who are even-toed ruminants.[11] Rhinoceroses are even-toed ungulates which have horns made of keratin; both sexes use these horns in contests with other individuals of the same species.[12] Walruses and elephants, non-ungulates, both possess elongated tusks. Apart from mammals, the only other group of land vertebrates that shows widespread adoption of weapons are the chameleons, who possess horn-like structures for fighting over access to mates.[10]

Some species of fish have weapons, though these traits are not as widespread as in mammals. Sawfish are named for their long rostrum, which can be used to inflict damage on other fish.[13] Unicornfish may also use their strange horn-like forehead protection as a weapon, although the general use of this and many similar structures in fish are still somewhat enigmatic. [10] Male salmon notably feature intraspecific competition for mates, and they use their elongated and toothy jaw to fight other males, both over access to females and over access to breeding sites.[10][14][15]

The horns of a rhinoceros beetle are an example of one of the many weapons insects possess.

Weapons are very widespread among insects, having been observed in nearly every major taxonomic group.[10] Insects possess a huge variety of weapons, often with entirely different uses and modes of action. Rhinoceros beetles, like the mammal they are named for, have large horns which they famously use to fight for mates.[16][17] Harlequin beetles have legs that are longer than their entire body, using which they protect a suitable spot for a female to lay eggs. They also posses strong mandibles to bite other males, which can include removing their legs.[18] Camel crickets use spines on their tibias for two reasons; (1) to fight other males for access to females, and (2) to pin mates as a form of coercion.[4][19] Among arthropods that are not insects, male fiddler crabs have large claws that comprise half their body mass and are used to attract mates elaborate waving displays with the claw.[20] They are also, though somewhat less commonly, used as a weapon to directly attack other males.[21][10]

Evolution

Animal weaponry is capable of drastic and rapid diversification in form with species within the same clade having distinctly different weaponry.[9] One hypothesized mechanism for this is the gradual change in weaponry function from physical agonistic behavior to weaponry display resulting in potentially more elaborate weapons present.[9] Another possible mechanism is the presence of male-male combat, with diverging lineages of animals expanding into different habitats and then fighting under different conditions. Changes in the physical contest between species in different environments may potentially drive the evolution in modified weaponry.[9]

Competition

Agonistic behaviors amongst animals for resources have been studied by many researchers, and specifically the interaction of weapons during these exchanges of behavior.[7] Not only the presence of weaponry, but also specific characteristics of the weaponry itself can have an effect on the outcome of competition in determining the winners and losers from an intraspecies competition.[9] The display of weaponry has been found to be favored in animals that frequently engage in contest as a mechanism to decrease the costs of aggression.[9] Displays are considered any behavior that is used to show a species' fighting ability without any physical contact. This behavior allows for rivals to have the chance to assess the weaponry that is present to determine whether to engage in physical agonistic behavior or not.[7]

Selection

Darwin's idea of sexual selection has been a main focus on weaponry and antagonist interactions between animals, with males that present the largest weapons having the highest probability of winning.[22] Sexual selection has been credited by previous researchers as the main influence of nature's extravagant weaponry for the purpose of attractive females.[9] During agonistic interactions, there is the potential risk of weaponry lost resulting in a possible decrease in an individual's fighting ability and overall fitness.[22]

Female Weaponry

Since Darwin's The Descent of Man and The origin of species, research has been heavily focused on weaponry in male animals, potentially leaving out females and their possible mechanisms behind present weaponry.[23] Presence of weapons in females, and female-female competition has been seen in many species for better fitness of both sexual and social selection.[24][23] Social selection, first hypothesized by Mary Jane West-Eberhard, is a broader term that includes both sexual and non sexual behaviors to increase an individual's fitness.[23] For example, research has suggested that horns present in female bovids, may have evolved from competition for resources such as food.[24]
