Did comrades that our body time after time always adapt and evolve? from generation to generation human face various types of diseases and trying to adapt to survive. The next generation is born tend to be more resistant to certain types of diseases after beaten up and mass extinction due to disease outbreaks. For example, the Mystery of the black plague more strongly to the evolution of human disease in the future. What is the black plague? Sedahsyat what the black plague? What is the black plague due to the body? This disease is a terrible plague in the 14th century can be healthier and live longer. But after this epidemic through human body evolved to become stronger. Analysis of the bones in the necropolis London showed a smaller risk of developing the disease.
Black pestilence, plague bacterium Yersinia pestis caused, invaded Europe in 1347-1351. In the span of just four years, the number of people that died 75 million to 200 million people - almost half of the population of Europe at that time - as a result of the outbreak. The victim died within days after contracting. Patients experience fever, swollen lymph nodes, rash, and vomiting blood. The name was taken from the appearance of the plague of black spots on the skin of a dead body.
Sharon Dewitte, biological anthropologist from the University of South Carolina, said the person's immune system is stronger Europe after the outbreak occurred. For years before the black plague happen, only 10 percent of Europeans who lived past the age of 70 years. Hundreds of years after the plague had passed, more than 20 percent of the European population lives beyond the age of 70 years.
"This is obviously related to the adaptation of the body," said Dewitte, as quoted by LiveScience, Friday, May 9, 2014.
Researchers previously believed the black plague kill anyone. But research shows that outbreak Dewitte has similarities with symptoms of other diseases: kill the elderly and those in poor health. Effects that plague immunity genes leave a trace on the descent of black plague victims or survivors. Descendants of the survivors of the plague could live longer.
To determine differences in human immunity due to the black plague, Dewitte examine human remains in Human Bioarkeologi Center, Museum of London. A total of 464 burial framework derived from three 11th-century and 12th before an outbreak occurs. 133 Sedangnkan framework derived from a funeral in the 14th century and the 16th. The framework was derived from people with diverse age and socio-economic backgrounds.
Dewitte report published in the journal PLoS One, May 7, 2014, shows the effects of a long life is a plague that claimed many older people and vulnerable people. With nearly half the population of Europe died from plague, the survivors have more resources and a lot of food to survive.
"Documentation of history suggests an improvement of nutrition, especially on the poor," said Dewitte. "They eat more meat, fish, and bread quality."
Black is a big outbreak of pestilence in the 14th century, unlike the current HIV or Ebola. Figuring out the response of the population to increase knowledge about the disease outbreak and human interaction.
The bacterium Yersinia pestis has now mutated and still cause deadly infectious diseases. But the pandemic level is not as high as it did in the Middle Ages. "Outbreaks like the black plague affect demography and human biology," said Dewitte.
