Where we come from? human origin of dispute (map)

The origins of mankind, there are two concepts: the origins of the human family and the origins of modern people. For one section of the common ancestor of about 700 years ago to 500 million years ago roots in Africa, the academic community is at present no less controversial.

For that the origin of modern humans exist two hypotheses, many scientists supports the "origin" in Africa, Africa is the home of modern man; a small number of scientists are supporting "in evolutionary said," that is, think that modern man is at the origin of the Eurasian non-respective.

Modern African origins of the view that the ancestors of modern people dates back to about 15 million years ago of a woman in Africa "Eve". The original Asian continent were all cold glaciers, natural elimination, the descendants of the "Eve" started by the African continent to the other continents of the world, migration within 5-6 years ago came to China, accrue multiply, and at the same time in all parts of the evolvement of the cave man is truly modern sense of the human race.

In 1987, the United States scientists Wallace and Wilson were led by two laboratory detection of mitochondrial DNA in the genetic material found that people today can be traced back to their ancestors to about 15 million years ago lived in Africa for a woman. After the start of the modern human part from the African continent to the world the other continents migration and at the same time the evolution of mankind by burrowing into real modern sense of the human race. This point of view this as an international academic argument of "focus".

On 7 March 2005 on Science magazine, published articles, Cambridge University's three researchers to modern humans from the African continent to the world the other continents migration of geographical location and the corresponding population study of gene analysis. Find the distance from Ethiopia (African and Eastern countries) and the Ethiopian room showed very little genetic variability. Modern humans began from the African continent to the world the other continents migration route, gene diversity characteristic manifestations not obvious, not a large number of gene disruption. This inference, which further proves that modern humans originated in Africa "said."

For "out of Africa," said one of the two key issues are migratory route. Two independent research team through the human mitochondrial DNA studies have found that the ancestors of modern humans as early as possible along the Indian Ocean coastline "out of Africa", and then move to the world, and its movement speed far beyond earlier estimates. The traditional doctrine that modern human ancestors might be moved to the Middle East and Central Asia region, and then to other parts of Asia and Europe, etc.

Another key issue is out of Africa. At first, scientists reasoned time in about 10 years ago, but after scientists a new round of analysis determined that the fossil is about the history of the Wannian 19.5 than it previously presumed earlier 6.5 million years. Genetic studies have speculated that Homo (i.e. people) should come from approximately 20 million years ago, but this new study results coincided with genetic research results.

Scientists believe that the revision of time so that the "modern humans originated in Africa" theory is more persuasive. Date of early modern ahead of time so that these people have more time to develop their cultural property, so they spread from the African continent to Asia and Europe.

Highly educated women sell egg money troubles and bad unknown

United States girls love for money to sell eggs back pain, there is no exact results

Someone from the egg donation in the pleasure of helping others, and some that are just for the sake of money. From ordinary thousands of dollars to the elite of 10 million u.s. dollars, these seemingly easy to get high returns for the young United States girls more of bikers. In addition to the contributions which have to put up with some pain, donors also face the risk of what kind of physical, psychological and social ethics at the individuals faced with what kind of pressure, yet scientists give exact results.

Jamie · Gallen Blech feeling is not very comfortable, but also no appetite to eat, because the previous morning her in the Hospital made a small operation of assisted reproduction, doctor spent 45 minutes from her ovaries extracted 66 eggs.

Although some physical endurance, but Ghar Blech think this just own a small price to pay, a couple from Boston to buy eggs paid her $ enough to let her 1.5 endure suffering. This is the QAR Blech 3 years the 4th best selling eggs, then she also intends to mid-July to New Jersey and then sell a eggs.

Section no. 000 donors

Ghar Blech in order to pay tuition to sell eggs, her fourth best selling the eggs of the remuneration is 1.5 million there is a saying more appealing, Ghar Blech is done to help others, this has fathered two children of the soldier's wife, hope those unhappy family can enjoy the happiness of childbearing. To some extent, this is, indeed, she frequently sell out the motive of the egg cell. In addition to? Ghar Blech to bank loans 1.4 million to pay tuition, she is in the United States well-known pure network University Phoenix University Ryerson. There are also people who rent, living expenses, these are also she had to sell eggs.

Ghar Blech selling eggs of remuneration in the "business" was relatively high, and the general price is around us $ 5000. Ghar Blech live in the United States of Michigan and the sale of eggs in Michigan is not legitimate, so she came to Massachusetts.

In the decision to purchase the QAR Blech eggs before the couple have been through del Blech from babies to teenagers to adults, each growth stage of the photo, they even look at Ghar Blech two children photos. 27-year-old GAL Blech 1.72 m in height, with a pair of green eyes and a natural blonde, looks fairly fine complexion, but ultimately the buyer choose Ghar Blech is because she's selling eggs prior experience, her first three selling eggs out of the doctor every time at least 40 eggs, this figure is generally sold twice the number of eggs, and Ghar Blech egg let three buyers are successful birth to healthy children, these experiences allow buyer is movable. It is also precisely because these good records, Ghar Blech price from $ 5000 to 8000 US dollars, it is up to us $ 1.5 million.

Ghar Blech and she is nursing sister University is planning to create an intermediary company, recruited other selling eggs ', the company came forward to find buyers and make contact. Currently, the two sisters have friends in recruitment to the part of those who are willing to sell eggs, she both also ambitious to find more like-minded persons.

Answer the questions who know their fate forecast formula of "death"

According to the associated press reported 14 United States researchers launched a prediction of the so-called "death" of testing services to answer to some questions you answer, you can know your "destiny". This service an airless and immediately had a great controversy.

San Francisco elderly Affairs Medical Center of Dr Lee on 11701 over 50 years of United States persons survey conducted extensive research, and health characteristics of the participants continued to track the last 4 years, design has the ability to predict the probability of death in 4 years "formula".　　Dr Lee said that the test of accuracy up to 81%. Prediction of the "death", the researchers for over 50 years of age in the crowd design 12 issues, by answering 12 questions, this answer to get score, and then set of formulas, you can know the odds of 4 years from the death.

Over a hundred-year-old's life and struggle of super human science

Cambridge genetics Department of Geriatrics biologists Aubrey de Grey (Aubrey de Grey) wearing dirty jeans with a pair of blue eyes, a long red complex beard, seems to be the core of Frankenstein. 　　　　But in the last year, this self-taught scholars to its theory on human aging aroused great attention. Mr. de Grey, 30 years later, human life has the potential to significantly extended. He said: "with drug efficacy, we must be like today treat many diseases, solving the problem of aging. "He believes today's many people may live to be 150 years old, or even longer. It's a bold prediction is based under the leadership of Mr. de Grey's a research project: "artificial control slow aging project". The research project to identify the seven and aging-related molecules or cells from damage, each "has the potential to solve through technical means, these technical means there's now exists, there is a positive development. "In the scientific community, de Grey has obsessed with suspicion. He is a pioneer or a nerd? is too naive or EVTA? but one thing is clear: his theory whether people agree that he's the man everyone is difficult to ignore. Chicago School of public health, epidemiology Professor Jay • aoshima ansky (Jay Olshansky) admitted: "I'm Aubrey fanatic admirers. We need him. I don't agree with his conclusions, but from the scientific terms, this doesn't matter, this can contribute to the advancement of the discipline. "De Mr. grey areas in other concerns are important. He became a new political movement in the United Kingdom the "spokesman". This political movement known as the "super human doctrine" (transhumanism), nowadays the Atlantic is getting more and more support. 　　　　The main credo of the campaign is the scientific and technological progress can give people free from disease and aging, let us live longer, healthier lives. "Super human doctrine" in the most basic form, is to promote we embrace new technologies, such as increasing intellectual drugs, surgical facelift and gene therapy, these new technologies can enhance our physical and mental ability, and let our "good good" is on the increase. Belong to the "super human doctrine" of some Futurists is even more extreme. For example, has recently published a new book "exceptional and not far away" (The Singularity is Near) Ray • Kurzweil (Ray Kurzweil) said, "ultimately, we will blend in with the technology ... To 2140, US intelligence in the capacity of non-biological parts will be the biological capacity of billions of times part. "These prophecies in the conservative religious and cultural community stirred up strong response, they think that super human is human nature. This prophecy as the freedom the leftist parties of bounce, they warned super human chauvinism may affect human equality and human rights. 　　　　United States scholar Francis • Francis Fukuyama (Francis Fukuyama) of the "super human" described as "the world's most dangerous idea". However, the human self improvement technique is starting from science fiction to go into the lab, and ultimately into the market, these response is no longer enough. 　　　　"Super human doctrine" is the driving force behind the progress that want to expand an existing pharmaceutical health care models, to enable mankind to live longer, healthier and more fulfilling. If these technologies are strict management, and truly allow public discussion, they have every reason to receive extensive support from the public. If you have a choice, most of us are willing to take this opportunity to live a longer, more than often say "life septuagenarians", even if we have to eat a wide variety of new drugs. Facelift for explosive growth illustrates that attitudes with each passing day. 　　　　These new technologies have to be tolerated by the people, but now it is in the TV show and fashion magazines, cosmetic surgery. 　　　　The key question is who can make the human self improvement and life extension ideas become mainstream? politicians and business leaders are trying to address the rising cost of pensions and health care, so you can understand that they may go to daydream a everyone can live 100 years old (but will also work) of the world. De Grey is Mr. himself as a champion of social reform movement, he must juggle callsign, let us start with the "support aging trance" awoke, not because of the State of impediment to seize the opportunities of longevity, etc. His arguments are not unreasonable. If politics is not to improve the quality of life, a longer life, then what is? super humans who have helped us a favor, to help us define a faction of political struggle, and this struggle has not begun.

The human body is a spontaneous combustion is still difficult to mysteries

The so-called human phenomenon of spontaneous combustion, refers to a person's physical contact with the outside world at the end of the race itself to ignition. This strange phenomenon, the oldest found in seventeenth-century medical reports. To the 20th century, there were 200 incidents occur.

At the beginning of the 19th century, some people think that this kind of disaster just befall those excessive alcohol obesity and women living alone. But the numerous examples prove that later, the approximate number of men and women victims of gender equality, age from infants to 114-year-old has a variety of age groups, and there are a lot of cases is no fire place themselves without burning.

Earlier most sufficient evidence that one of the spontaneous events, the human body by Bartok forest in 1673, made a record. That was a poor women in Paris, one night went home to bed after a night of spontaneous combustion. The next morning she was found only in the head and fingers left over from the other parts of the body burning to the ground. According to this spontaneous events from France who Maurer in 1800 published its first articles about the human body to spontaneous combustion.

After a short time, France, United Kingdom, intended to facilitate had caused a sensation of spontaneous combustion in the human body. A recent comparison of influential 1976 27 December, from the Al Leah Herald "reported by La Goss, a family of seven, six members of the burned to death, became the most difficult to explain the mystery. Report says: "the field investigation showed that the wood room all objects intact, even the bedding also neatly on the bed, but they burnt the severity of the deceased, the room should not in all."

Although a lot of police, fire brigade, arson cases expert, pathologists have made a lot of evidence, but at present there is no reasonable arguments to justify human physiology is spontaneous or even reduced to ashes. In accordance with the general terms, the body's organs and tissues and bones only 900-1000 degrees Celsius of hypertension may crematoria burned to ashes, and its own incredible combustion. In addition it has been suggested other spontaneous factors, such as Meteor, lightning, explosion, in Atomic laser beam, magnetic energy, etc., but these kind of conditions we can play a role in formation of spontaneous combustion, there is no explanation. In short, the human body to spontaneous combustion phenomena is still a difficult puzzle.

"Heart" of the driver to the poet's heart with memory function

United States scientists study found that the human heart and maybe some kind of "thinking and memory function"! this is what many patients receiving a heart transplant surgery personality change, inherited the heart donor personality. According to statistics, every 10 cases accepted for heart surgery patients, there is one character change occurs.

"Heart" drivers become poet

It is reported that United States 40-year-old retired truck driver Jim · Clark has never been an unhappy person, he never gave the wife Maggie wrote a letter, since he was 15 he left school, grammar errors. So when the last day, Jim suddenly sit on the table and began to write a line to his wife love poems, expression and emotion, he felt a shock. Original, JEM in half a year ago has just received a heart transplant surgery, he was convinced that his poem "quirks" comes from the heart of the transplantations, because the donor family loves writing poetry.

Heart memory cells work

Mathematical Association of United States California heart experts also believe that the heart is not a "pump", they have recently found a way to have a long-term and short-term memory of neurons is indeed in heart, and a small but complex nervous system. "Memory" of the heart with perspective is still not recognized by the mainstream medical profession, but many accept the heart transplant patients are convinced that there is no theory can explain in their possession of a series of strange things.

A pregnant belly twins fratricidal helpless killed a PO-a

According to the United Kingdom the mail on Sunday reported 19, conceives twins of United Kingdom Nottinghamshire 26-year-old woman Sarah-gelatt was the doctor informed, a rare disorder leading to her belly of a fetus is slowly killing another fetus. Sarah either combine the two fetuses with abortion, or risking abortion one tire, save another fetus.

Painful Sarah decided to accept the operation, kill a fetus that rescuing another fetus. It is reported that the Sara there are already 4 months pregnant, she encountered is the rare "twins reverse artery reperfusion syndrome", this means her womb of one embryo congenital organ disorders, there is no chance of survival, but it is still growing, the health of the fetus from the body to draw blood. If Sarah continued pregnancy, then the two fetuses have no chance of survival.

It is reported that on 21 February, the United Kingdom Birmingham women's hospital physician through a keyhole surgery "," end the patient's pregnancy, fetal surgery may result in the Sala fetal health also abortion. According to experts, the termination of pregnancy for fetal will still remain in the Sala of the uterus, but the doctor said that, if the operation is successful, the killed the fetus will not affect the other healthy fetal life. It is reported that the "twin reversed arterial perfusion syndrome" only occurs in pregnant women with twins, this disease is so rare, each 35000 pregnancy may appear only in a case. (Clancy)
