Neanderthal DNA Lives On in Modern Humans

Study: Neanderthal DNA Lives On in Modern Humans

By Jennifer Pinkowski, courtesy of TIME 

A decade after scientists first cracked the human genome, researchers announced in the May 7 issue of Science that they have done the same for Neanderthals, the species of hominid that existed from roughly 400,000 to 30,000 years ago, when their closest relatives, early modern humans, may have driven them to extinction.

Led by ancient-DNA expert Svante Pääbo of Germany’s Max Planck Institute for Evolutionary Anthropology, scientists reconstructed about 60% of the Neanderthal genome by analyzing tiny chains of ancient DNA extracted from bone fragments of three female Neanderthals excavated in the late 1970s and early ’80s from a cave in Croatia. The bones are 38,000 to 44,000 years old. 

The genetic information turned up some intriguing findings, indicating, for instance, that at some point after early modern humans migrated out of Africa, they mingled and mated with Neanderthals, possibly in the Middle East or North Africa as much as 80,000 years ago. If that is the case, it occurred significantly earlier than scientists who support the interbreeding hypothesis would have expected.

Comparisons with DNA from modern humans show that some Neanderthal DNA has survived to the present. Moreover, by analyzing ancient DNA alongside modern samples, the team was able to identify a handful of genetic changes that evolved in modern humans sometime after their ancestors and Neanderthals diverged, 440,000 to 270,000 years ago. 

The process of sequencing was painstaking. Among the challenges were eliminating bacterial and fungal DNA, which accounted for 97% of the genetic material in the samples, and guarding against contamination from the researchers, whose DNA might be mistaken for Neanderthals’. Plus, the DNA was so fragmented that the chains were often no longer than 40 or 50 base pairs. "We used half a gram of bones to produce the 3 billion base pairs," Pääbo said in a May 5 press conference. "I really thought until six or seven years ago that it would remain impossible, at least for my lifetime, to sequence the entire genome." New sequencing technologies made it feasible, he said. 

Researchers compared the Neanderthal genome with the genomes of five living people: one San from southern Africa, one Yoruba from West Africa, one Papua New Guinean, one Han Chinese and one French person. Scientists discovered that 1% to 4% of the latter three DNA samples is shared with Neanderthals…

Not So Fast: China Will Not Allow Use Of Yuan As Bargaining Chip To Resolve Trade War

Courtesy of ZeroHedge. View original post here.

With market optimism brimming that it's just a matter of days, if not hours, before the US and China reach a truce in the ongoing trade war - even though there have been countless accurate analyses in recent weeks explaining why an actual trade deal is impossible since the object of contention is not trade at all but China's creeping technological dominance, something which Beijing will never voluntarily concede - Beijing has poured cold water over expectations of an imminent deal when China's Ministry of Foreign Affairs said on Wednesday that Chi...

Are Bank Stocks Ready to Right-Side the Bull Market?

Courtesy of Chris Kimble.

The bank sector is a good indicator of the health of the broader stock market.

Bulls like to see the banks in a leadership role because it indicates that the economy is doing well. But when they begin to lose momentum and underperform, it often leads to pullbacks and corrections.

As you can see in today’s chart, the Bank Index (BKX) began to stumble well before the recent correction. And that bearish divergence was a warning to market bulls – similar to the 2015-2016 setup.

On the other hand, the recent rally has given bulls an opportunity to right-side th...

While no immediate catalyst (headline or technical level) is clear, increasing chatter over institutional investors dipping their toes in the space have prompted an extension of the positive trend.
