Sometimes you wonder just by watching what "important" issues solve the most lucid minds of the planet. We offer you an interesting selection of weird and silly questions, which once wondered science.
1. "As a male turkey will respond to the severed head of a female?"
In 1965, researchers at the University of Pennsylvania Martin Shein and Edgar Hale began to experiment to find out whether the turkey is needed for a complete set of mating females, or rather one single head.
For this, they have made several models of turkey and slipped them turkeys. Those substitute and did not see them as any normal turkey would do with a normal female. After that, the scientists cut models with legs, wings and tail, but the turkey is also not at all embarrassed.
Scientists gradually cut from a piece of artificial turkeys, until finally, not left alone head. But even in such a model is not lost for turkeys sex appeal.
After that, scientists have moved on to the next part of the experiment, in which the turkeys offered to mate with females of real beheaded. The result was the same.
2. "Can I get a turtle yawn, yawn if the muzzle in front of her?"
Everyone knows that yawning is contagious. One yawn - even in the office, even though the bus - and started a chain reaction. And this happens not only with people - try to experiment with your dog. A group of scientists interested in this phenomenon and decided to whatever was to find out whether it applies to turtles.
To start should teach at least one tortoise to yawn on command, so you can check the response to the yawn it from other turtles. Therefore, Dr. Anna Wilkinson of the University of Lincoln (England) currently selected red-turtle and spent six months on what to teach her yawn.
The learning process was as follows: Uilkilson spent hours putting to his ward a red cardboard, and as soon as she opened her mouth and made a movement similar to a yawn, betrayed her a piece of lettuce. After a few months the turtle has learned to open her mouth and no salad, just the sight of a red cardboard.
Then they hoisted the reptile to the yawning of her relatives, and ... nothing happened. It was found that yawning for turtles is not contagious. It turned out that this is more a social phenomenon is not peculiar to the animals' lower order ».
Commenting on the results of his investigation, Wilkinson noted that any information about the social behavior of reptiles can be useful to save the endangered species.
3. "As the voice of the monkey sounds under the influence of helium?"
In order to answer this vital question for mankind, an expert on primates at the University of Kyoto (Japan) Takeshi Nishimura planted gibbon in helium-filled chamber. The result? Instead, this kind of peculiar cry from the gibbon was to leave something like a groan of death frightened ghost.
Although, in fairness it should be noted that this experiment was not so meaningless as it may seem. Nishimura was trying to understand the mechanism by which the sound of gibbons recovered, and it turned out that the system works for them, much the same as ours, but we specialize in speaking, and they - on singing.
4. "What happens if the lodge male dolphin from a human female?"
In 1965, researcher John Lilly dolphins and his team conducted an experiment in which over 10 weeks dolphins taught the basics of human language, including the concepts of colors and numbers. Training took place with the help of games with special cards.
Lilly considered that the establishment of an ideal contact is best to experiment to isolate the male dolphin from neighbors, put him in a separate pool with a person of the opposite sex. The latter was chosen as student Maggie Hou. She lived in a room where all the furniture was half flooded to Peter dolphin could swim to it at any time.
In general, Peter Maggie came to the heart, if not more.
At first the dolphin behaved like a perfect gentleman, expressing their feelings through an offering in the form of frozen fish. But Maggie did not take seriously courting that Peter, as it turned out, it is not suited. He began to bite the girl, and even beat the means available to it to bruises - to make it clear on their unique sexual harassment.
Scientists became concerned and decided from time to time send hot dolphin females the corresponding species. But nothing they did not work, because Peter appeared in the one-woman man and decided that no matter what the favor of Maggie.
As a result, for the sake of the experiment, Maggie agreed to stimulate the penis when the dolphin foot, and when the hand in exchange for Peter to take part in a number of important experiments.
After the experiment Maggie wrote a very indecent report.
Lilly considered this study a great success, as did Peter mastered a few basic linguistic concepts.
5. "Can chimps to know each other on the ass?"
Fortunately, unlike the first experiment, with turkeys, to answer this question, scientists had not occurred to cut off the chimps ass. This time it was much more humane - Franz de Uaal and Jennifer Pokorny made a lot of photos depicting the fifth point of the different chimpanzees.
Then they took away the six most smyshlёnyh chimpanzees and showed them the pictures, among which they would find familiar. And monkeys mastered! This, according to scientists, shows that chimpanzees, like humans, are able to get an idea about the entire body as a whole - unlike cats, for example, which can enthusiastically chasing its own tail.
6. "What is man will face if to make him cut the head off a rat?"
In 1924, a graduate student named Carney Landis had a very strange experiment. He scored volunteers painted on their faces a few lines, the better to observe how the expression will change, and forced to do things that were supposed to disgust: iron frog, considered pornographic pictures ... all that stuff. And he is currently shooting their faces.
In the final, he gave all the white rat and asked to cut the animal's head. Amazingly, most of the subjects completed the task. Over a third of people who refused, did scientists themselves.
As a result, Landis found out only that there is some universal for all the grimaces of disgust. Here are some of these pictures:
Pay attention to the child in the photograph 7 and 9. The boy is only 13 years old; he was careless enough to appeal to the lab where Landis worked as doctors suspected that his heart condition is partly psychological roots. Perhaps Landis just wanted to see if science is to grow from an ordinary boy's poor health of the serial killer.
