    Animal seduction in eight stages

    Animal seduction in eight stages

    When we know that the panda naturally produces nearly a thousand perfumes, that the song of the lark knows hundreds of variations and that many insects offer gifts to their sweetheart, the question arises: what can we learn about nature? drag? Eight things to know. 

    1. The male seduces, the female chooses

    In most animal species, it is the male who sings, dances or fights to attract the attention of the female, who will then choose the most beautiful, the most talented or the strongest male available. Why ? To sum up, two strategies clash: quantity versus quality. On the one hand, "males want to copulate as much as possible to ensure their offspring", summarizes the ethologist and primatologist Daniel Paquette. And females, they seek to select the best genes. "Because they carry babies, their reproductive strategy can not be to have them as much as possible. They aim rather at the quality of the offspring. "

    2. That the best singers (and dancers) win

    The lark can sing for 40 minutes without stopping. While doing its courtship, the albatross adopts more than 20 different postures. No, it does not belong at all to the coquetry. In fact, singing or dancing requires unsuspected strength and energy. This is precisely what the female judges and evaluates here: which of her contenders has the most power and vigor? Which will bequeath the best genes to his offspring? Certainly not the poor dancers! "Dance is a weapon of massive seduction! ", Says the scientist and humorist Boucar Diouf, who wrote a book on the subject (For a reason X or Y). A weapon that is so successful in humans, he says.

    "It's been proven that a guy with a guitar on his back has a lot more luck with girls than a comedian who tells jokes! That, the cicada understood it! "

    3. Beware of poisoned gifts

    Just like singing or dancing, it is not (for) their beautiful eyes that males offer gifts to females. In fact, when a marine bird deposits a small fish at the foot of its sweet, or when a gull regurgitates his last meal, it is rather to demonstrate his qualities as a fisherman, his ability to feed the female and possibly his young. But not all males are so well intentioned. Some species of flies wrap their gifts with silk. "They save time: while the female unwraps the gift, they can mate longer! ", Illustrates the author Jean-Baptiste de Panafieu, who has just published Séduire as a doe, an essay on the subject. And there is worse: others offer outright empty packages, to enjoy free of the female during unpacking ...

    4. The benefit of being a good handyman

    In some species, especially in birds, do-it-yourself males are the most popular females. Always according to the logic that it is necessary to choose the best genitor and the best protector, in the tits, in particular, "there is really a very thorough observation of the female when the male makes his nest, continues Jean-Baptiste de Panafieu. It is necessary that the construction is beautiful and solid to attract the female ". "The female will lay if the nest pleases her. And if the nest really pleases her, she will also hatch the little ones. If not ? She leaves them to the male and goes elsewhere ... "

    5. The success of experienced females

    In general, females prefer older males because they are stronger, more experienced and more able to protect them. But in some cases, it is rather the males that favor experienced females. "Chimpanzee males prefer older females because they are more experienced as mothers and more sexually experienced," says animal behavior specialist Daniel Paquette (to whom we owe what chimpanzees taught me), pointing out by the way, unlike humans, female chimpanzees do not go through menopause.

    6. Everything is in nature

    An example ? In Australian black swans, 20% of pairs are composed of two males. "And they will manage to get young, either by seducing a female and chasing after the laying, takes Jean-Baptiste de Panafieu, or by spiking eggs to straight couples. Better: the little ones here will have a better life expectancy because they will be protected by two males. On the European coastline, some bird species are squarely "trouples", consisting of pairs of two females and one male, mating with each other and producing more than the average size.

    7. Unfaithful one day...

    Birds have long been thought to be examples of monogamy. In some species of seabirds (including seagulls), we see pairs forming, having pups, dealing with them together, and lasting until death. However, recent DNA research has shown that the reality was different. For some, "up to half of the children are from an unofficial father," laughs Jean-Baptiste de Panafieu. And this extramaritality is not exclusive to birds, far from it. In marmots, one in three is "illegitimate".

    The final word

    Of course, the parallels with the human species are easy, fast and above all fun to do. "Anthropomorphism, to make you smile, is acceptable," says Boucar Diouf. But do not try to draw here great lessons of life. "It is always extremely dangerous to draw parallels between the animal and human worlds," concludes the director general of the National Institute of Scientific Research (INRS), biologist and ethologist Luc-Alain Giraldeau. In his book Dans l'oeil du pigeon, he defends precisely this thesis. Because beyond the courtship displays, there are also animal practices that are definitely less rosy.

    "It's not glamorous, it's not romantic, but in nature, there are also plenty of animals where males take females forcibly."

    The best (or worst) example is certainly that of the bedbug. Imagine that madam does not have a "genital opening". Sir, conversely, as a reproductive organ, has a "dagger". To fertilize it, he must literally pierce it. Less romantic than that, you die...
