Mother Gives Birth to Baby Can Substitute Neanderthals?

In a controversial interview, a distinguished professor of genetics at Harvard stated “women who have an adventurous spirit high” could someday become a surrogate mother (surrogate mother) to Neanderthal cloning babies.
Besides saying that cloning will be possible Neanderthal baby, George Church told the magazine Der Spiegel that use stem cells to create a Neanderthal could have significant benefits for the community. “The first thing you should do is sort the Neanderthal genome, and it’s actually been done,” said Church.
“The next step is cutting the genome into, say, 10,000 pieces, and then … collect all the pieces are in human stem cells, which will allow you to finally make a clone Neanderthals, “he told Der Spiegel Church.
The scientists completed the first sequence of the Neanderthal genome in 2010, found genetic evidence suggests that the ancestors of modern humans successfully interbred with Neanderthals, at least sometimes it happens. Recent research suggests a Neanderthal DNA making up 1 to 4 percent of modern Eurasian human genome.
The benefit, according to the Church, including increased genetic diversity. “The bad thing for the community is the diversity of the low,” said Church. “If you become a monoculture, you have a great risk of extinction. Therefore the re-creation of the Neanderthals would be a major effort to avoid social risks. “
In his book “regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves” (Basic Books, 2012), Church wrote, “If people become comfortable with cloning and see the value in true human diversity, the whole thing can be cloned Neanderthal by chimpanzees as mothers replacement – or by women who are adventurous high. “
Church said in another interview that he is not advocating for the birth of a baby from a surrogate mother Neanderthals in the near future, but people have begun to discuss the idea today that we’re ready for the future. However, other scientists say the idea is not only problematic in terms of ethics, but it is scientifically impossible to do in the future.
Ethics of human cloning
Not everyone agrees with interest Church in cloned Neanderthal, given the ethical issues involved.
“I think it is unfair to put people … into a situation that makes them feel humiliated and scared, “says biologist ethicist Bernard E. Rollin of Colorado State University in Fort Collins told The Independent newspaper.
There is also the possibility of Neanderthal infants will lack contemporary immunity against infectious diseases, and therefore would not be likely to survive, according to the Independent. Neanderthal man closest genetic relatives are unknown, died about 30,000 years ago. However, recent research suggests that Neanderthals and other extinct humans might have endowed Denisovan as some people with strong immune systems.
