Homosexuality and sexual Strange Things in the animal world
Some people believe that sex in the animal world contains not only on the sexual practices as "normal", but the truth is far from this belief, is found among animals in homosexual practices between males, and sex between females just as similar to homosexuality in humans, and during the next lines we will try to shed light on Some examples of animal species that have sex in ways that "abnormal" ...
Has provided a recent U.S. study by the University of California, amazing results on the causes of homosexuality in several species of animals and birds, could open the door to identify the causes of the phenomenon in humans as well, but some may cause a negative impact for homosexuals.
Although scientists know for decades, and there were cases of homosexuality in animals from different factions, including birds and reptiles, but it was confusing, as the reasons for the persistence of these practices is still unknown, especially as it does not lead to reproduction and breeding.
Among the assumptions that came out of school after a year-long research, that the abnormal practices of animal does not include access to a permanent partner, but that some animals do not exercise this kind of sex only in the absence of females, and if they return, these practices disappear.
Strange Things in the world of animal sex
For example, the lion at 50 intercourse in the day, when the female in the case of accept, and only 1% of the times lead to pregnancy.
The biologists noted that the Australian male frog is trying to have intercourse with anything is in their way, like a bottle, females and even dead fish, which may lead to death of fish at times.
The pygmy chimpanzee uses sex in order to maintain social ties in a clan, everyone is having sex with everyone, without exception, at all times, male with male, male with female, female with female, adults with young children, especially when the differences between members of the clan.
There is a kind of banana flies have semen container to a toxic substance to the extent that destroy the female completely, but its slow to cause the female to produce eggs fertilized to die later, thus making the male killer is the first and last in her life.
As some animals and insects have another effective way to prevent the mixing of "genealogy," a close female genital opening after the intercourse, so as to prevent occurrence of sexual intercourse before the last fertilize an egg.
For example .. Male rats household has its means a substance intended to be converted to a solid close when the female genital opening long enough to fertilize the egg when these mice are "Cork" rigidity to the extent that the affected mouse If one attempts to remove Altsekerp force.
A world where rape and violence ...
And some animals, nature, wild creatures have pawns and Gdedda toxic, when Spider Alakrbi like intercourse rape, above, holds the first female to meet, and withdrawn to his cave, and there are addresses on the back of the ground and rubbed her back until soft, then treat genital orifice in the same way to to open its means to put the semen and thrown to the outside.
The One type of lice to the way the heaviest males, the male member will hooked and thus beat him over the female, without specifying the place, Vijrgaha where you hit it it, and the sperm were looking away from the place of the egg.
It's the same when the type of worms that belong to the group "Onychophora", where the process of pollination is more brutal, puberty Mnoyate put on the back of the female which contains a special enzyme to carry out a hole in the skin of a woman in the back to open the way for sperm to enter the body female and the search for eggs.
Either when the female dog by clicking on the penis so as not to allow him to disengage after ejaculation, so as to give to the female to male Mnuyat chosen by the opportunity to reach the egg, this prevents the rest of the males to engage in a critical period at least, and thus preserve the egg has already been vaccinated Mnuyat of the dog they have chosen.
There is some kind of green locust, where the female from eating the tip of the penis during the process of pollination and before it's over, the male body just unable to continue to complete the process of pollination without the head, but the female need for more power during the process of the vaccine, which is paid to the use of Ras Mqahha.
And the world live without sex ...
Researchers reported that there is a kind of Amazonian ant has been abandoned with the evolution of sex and turning into a society of all females and reproduce this kind of ants, known as "Mikosiboros smithii" through the reproduction of queens for the production of genetically female matches.
The Professor Anna Himmler at the University of Arizona, that this type called "a world without sex", where he found that the genetic fingerprint of each ant identical and cloned from the Queen, pointing out that the study of these insects were found to be capable of sexual encounter.
Himmler explained that in insect societies are several types of beings, but this type of ants in the evolution of revolutionary unusual, saying she and her colleagues do not know what became of this type unisexual hundred percent, and how long it took to achieve this development.
Himmler and concluded that it will be further genetic experiments to determine how much of the time because of this revolutionary development is unusual, there is an advantage to a life without sex, explaining that doing so would "avoid the cost to produce the genetic male, double female products, thereby doubling each generation by one hundred percent ".
The diversity in the insect world produces generations are better able to resist disease, which does not occur in insect populations reproduced if there is a problem in one, it will move automatically to the other
Amusing tales of marriage
Female hyenas prefer not to consanguineous marriages
A recent scientific study confirmed that female hyenas prefer not to mention that you know is in marriage, where the hyena said, who leaves his flock lucky in love, because their female partner affect male strange mysterious about it that you know.
The researchers pointed out that the preference for male stranger help to avoid limiting the reproduction in a narrow range with each group of hyenas.
The researchers in their study, published in the journal "Nature" that males that have been observed to respond to female preference was to have the highest rate of success in breeding in the long run.
The researchers monitored the progress of eight breeding groups hyenas in the Ngorongoro Carter, a resident in Tanzania and then identified and genetically parents hyenas during the nascent period of ten years, and felt that the reason for the exodus of most of the male away from her group of origin is the preference of females to males who have joined the new group of migrants who are male from another group after the birth of female.
They said that unlike humans, female hyenas do not want to know the young to their father because he does not participate in the upbringing of his sons, and the female animal spotted hyena, which meet many of the male during its life.
M octopus paired in the dark
A recent scientific study showed that the process of mating said Australian octopus are often in the dark, so it does not know whether he was dealing with the LLC or female care only after the sensitive target.
Mating is achieved after the Sun octopus legs tucked into the body of the other, so I said courting male octopus error like that female but this meeting ends quickly and amicably, and the meeting between a male and female partner Octopus has prolonged for more than an hour and a half hours to make sure of the success of the enrichment process.
Birds "Goldfinch" is not only one pair
In the same context, a scientific team confirmed that 25% of female goldfinches not to just one pair, where tests confirmed the DNA of eggs and excreta in Bash, the different genes and genetic information, evidence of the presence of more than one type of influenza and scientists to explain females resort to cohabitation with more than a bird, the belief that this will help to fertilize the eggs well.
He pointed out that one of the scientists are not sure yet whether these boys of the same type or of other types.
Female nematodes turn to a male for breeding
U.S. scientists found that female nematodes change their sex before they reach the stage of the targets, where you expect if the female in the season that will live a prosperous season at the age of life and reproduction, they remain on the female sex, but if it becomes barren season to be stated.
Has a female nematode chromosomes of the two "X", while the male chromosomes and has one of it, if the female is felt that the season will be very prosperous after puberty, it would abandon its chromosome "X" for one to become a male, genetically, as the numbers of male worms is less than than females, and females can vaccinate themselves to have children if they can not achieve stated.
Insect cicada out after 17 years of marriage
More recently, plains, Virginia, American insect "cicada", known in English "Cicada", and lives of these insects in the ground and feed on the roots of trees, and out every 17 years to mating for a period of two weeks, then lay eggs before they die and perish.
The advantage of the life cycle of this insect as stated longer than the female that die as soon as the egg-laying
