    Direct exchange of meat for sex has not been observed. The benefit of gaining stones without a fight is clear, but the female is not always willing to copulate to avoid a fight. When the females arrive, sometimes a few weeks later, they go right back to their mates from the previous year. But the well-dressed animals share many common features with other birds, particularly when it comes to mating. The discs could be exchanged by the monkeys for various treats.

    There are about 18 species of penguins , and though their mating behaviors are "fundamentally similar," each species has its own quirks, said penguin researcher Emma Marks of the University of Auckland in New Zealand. But researchers are still studying the phenomenon, and a consensus has not yet been reached; it is assumed that either the female is baiting, or that the male deliberately chooses to misinterpret the gesture, as coercive sexual copulation is common among these penguins. The researcher took steps to prevent any possibility of coins being traded for sex after his suspicions were aroused. The ritual helps the birds get to know one another, and learn their respective calls so that they can always find each other. In species that don't build nests, the adults incubate by balancing the eggs on their feet. A study conducted by the Max Planck Institute for Evolutionary Anthropology in Leipzig , Germany , and published online in the Public Library of Science , attempted to support the meat-for-sex behaviour hypothesis, according to which, in early human societies the best male hunters had the maximum number of sexual partners. Sometimes copulation doesn't occur, but the female still takes a stone. The data show that when extrapair copulation occurs at the male's nesting site, the female takes one or more stones; but when the extrapair copulation occurs at the female's nesting site, the male never takes a stone. But both males and females steal stones: A female will check out the quality of her old flame's nest by inspecting it, getting in it and lying down. Courtship complete, the pair then mates. This would provide a female penguin with another male penguin should their current mate die. Clearly a male who has copulated with a female benefits his progeny when she takes a stone. The researchers speculate about the possible genetic fitness advantages and disadvantages of the practice, and aren't altogether sure that the female copulates mainly in order to obtain a stone. In Emperor penguins, the male takes care of his egg for two months straight, relying on the warmth of his fellow penguin papas to survive the cold as his fat reserves dwindle. Breeding usually takes place during the Antarctic summer October through February , though some species do mate in the winter. After the female lays one or two eggs, the male will take the first incubation shift. In an actual study the researchers speculate that the female has bent over to grab a stone and the male has misinterpreted the gesture—she hasn't changed her mind or performed a trick. According to Hunter's observation, the number of prostitute penguins was very low, and she approximated this as "only a few percent". The male penguins, the study speculates, were engaged in sex with the prostitute females only for sexual satisfaction. She will do the same for neighboring nests, though this can sometimes lead to trouble. Unable to study early humans, researchers studied chimpanzees. Direct exchange of meat for sex has not been observed. These prostitutes have sex with unattached males and take a pebble from the male's nest after having sex. During one chaotic incident, a researcher observed what appeared to be a monkey exchanging a disc for sex. The BBC further reported Hunter as saying that the female penguins probably didn't engage in prostitution only for stones. The monkey that was paid for sex immediately traded the silver disc for a grape.
