"About 700 years later, too lazy, people on earth generally fat, feet due to degradation has been unable to walk upright, everyone is like a bubble in the air, only mobile floating chair sitting, like the stalls in the chair a pile of flesh ... "This is a 2008 swept the world of American science fiction animated" Robot Story "scene depicted on the future of humanity, although there are some jokes and banter, but the film also revealed concerns about the future of humanity degraded.
Recently, some of the information from scientific research institutions show: humans are getting shorter, fat, and its skull capacity showing a downward trend, so some people began to worry about: grow shorter ugly stupid in the future will become humans can not escape the fate?
Natural selection has never been human failure
Many biologists believe With the continuous development of human society advanced medical technology and the improvement of social welfare measures, mankind no longer need for survival, struggling, cell phone case wholesale natural selection of evolutionary theory are no longer applicable, the human is no longer evolution.
But there are a lot of anthropological researchers oppose this view. Throughout the biosphere, natural selection has always been the objective existence of the human into the civilized society is still no exception, no matter how human technology and culture development, they always play a leading role in the chain of human evolution, can not eliminate the role of natural selection in the face of technology and culture, human natural selection process will be subject to some interference, but this is still the selection mechanism will quietly play a role in the Institute of Vertebrate Paleontology and Paleoanthropology, Research Associate, Lee Chun-cheap cell phone cases .
In recent years, some foreign researchers through the sample study found that the human is still evolving scientific and technological progress and cultural progress is still not rid humanity of the law of "natural selection" in complying with the laws of nature.
October 7, University of Montreal, Quebec, Canada Branch researchers said they Aoku De Island, 80 kilometers northeast of Quebec City, Canada, found evidence of human evolution.
Aoku De Island residents and ethnic structure of a single, similar levels of education, believe in the same kind of religion, is an ideal sample of the data analysis. Researchers access to registration records of the local church from 1799 to 1940, found that in 140 years, women's first child, aged about 26 years old to 22 years of age.
The exclusion of social and environmental impact factors, the researchers found, their first child early women by nature favor. Other sample studies have reached the same conclusion.
In addition, in the second half of 2009, the evolutionary biologist Professor Stephen Stearns of Yale University and his research team are also the U.S. National Academy of Sciences published studies have reported that through research, they found that body weight, height genetic characteristics still influence the number of children of women and children's health.
The researchers found: Compared with lean women with higher partial short little fat of female children born; fertility earlier, stop by the late, as well as blood pressure and cholesterol levels lower than women usually have a family. In addition, the characteristics of these favorable human reproduction will be transmitted to the daughter of these women, the daughters tend to have more children.
Obviously, natural selection is still quietly play a role
