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…

"Tool Of Terror": This Killer Opioid Could Be Used As "Weapon Of Mass Destruction"

Courtesy of ZeroHedge. View original post here.

Fentanyl is so powerful that a few milligrams can be fatal. It would take about 40 pounds of fentanyl to kill everyone in New York City and 1,515 pounds to kill almost all Americans. This killer opioid is so potent, according to Bloomberg it could be used as a "weapon of mass destruction," adding that national security experts are becoming increasingly alarmed at the prospect of it being used in the next terror attack.

Regional Banks About To Send Important Message!

Courtesy of Chris Kimble.

Large and Regional banks have struggled this year, as both indices have declined nearly 15% in 2018.  These declines have taken place as interest rates have been moving higher, which historically is positive for banks.

The declines of late in Regional Bank ETF (KRE) has it testing 7-year rising support as well as the 2007 highs at (1).

The Power of the Pattern is of the opinion, what KRE does at (1), will send an important message to the banking industry and the broad markets.

Keep a close eye on KRE in the weeks ahead friends, this looks to be an important test of support!...

Nearly 170 years before the invention of Bitcoin, the journalist Charles Mackay noted the way whole communities could “fix their minds upon one object and go mad in its pursuit”. Millions of people, he wrote, “become simultaneously impressed with one delusion, and run after it, till their attention is caught by some new folly more captivating than the first”.

Weekly Market Recap Dec 09, 2018

Courtesy of Blain.

Bears are certainly showing the type of strength we haven’t seen in a long time.   A week ago at this time futures were surging on news of a “truce” for 90 days between China and the U.S. in their trade spat.  But the charts were still not saying lovely things despite a major rally the week prior.   And by Tuesday, darkness had descended back on the indexes, with another gut punch Friday.    A lot of emphasis was put on a long term Treasury yield dropping below a shorter term Treasury.

On Monday, the yield on five year government debt slid below the yield on three year debt, a phenomenon which has p...
