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…

Will COVID-19 Lead To A Gold Standard?

Authored by Alasdair Macleod via GoldMoney.com,

Even before the coronavirus sprang upon an unprepared China the credit cycle was tipping the world into recession. The coronavirus makes an existing situation immeasurably worse, shutting down China and disrupting global supply chains to the point where large swathes of global production simply cease.

The crisis is likely to be a wake-up call for complacent investors, who are content to buy benchmark bonds i...

Gold Rallies As Fear Take Center Stage

Courtesy of Technical Traders

Gold has rallied extensively from the lows near $1560 over the past 2 weeks.  At first, this rally didn’t catch too much attention with traders, but now the rally has reached new highs above $1613 and may attempt a move above $1750 as metals continue to reflect the fear in the global markets.

We’ve been warning our friends and followers of the real potential in precious metals for many months – actually since early 2018.  Our predictive modeling system suggests Gold will rally above $1650 very quickly, then possibly stall a bit before continuing higher to target the $1750 range.

The one thing all skilled traders must consider is the longer-term fear that is build...

Precious Metals Eyeing Breakout Despite US Dollar Strength

Courtesy of Chris Kimble

Gold and silver prices have been on the rise in early 2020 as investors turn to precious metals as geopolitical concerns and news of coronavirus hit the airwaves.

The rally in gold has been impressive, with prices surging past $1600 this week (note silver is nearing $18.50).

What’s been particularly impressive about the Gold rally is that it has unfolded despite strength in the US Dollar.

In today’s chart, we look at the ratio of Gold to the US Dollar Index. As you can see, this ratio has traded in a rising channel over the past 4 years.

The Gold/US Dollar ratio is currently attempting a breakout of this rising channel at (1).
