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…

Depression Coming or Is the Bottom Already In? Joe Friday Says Your Answer Lies Here!

Courtesy of Chris Kimble

Are we headed towards a Depression or is the worst already behind us? In today’s world, comparisons to the great depression are easy to find.

Are the Depression concerns well founded or are the declines of late already pricing in a bottom?

In my humble opinion, this chart and the upcoming price action of this index will go miles and miles towards telling us if we are headed towards very tough times or if the huge declines of late are actually in a bottoming process.

This chart looks at the Thomson Reuters Equal Weighted Commodity Index on a monthly basis over the past 54 years. The index has been heading south, reflecting weakness in demand for basi...

Anyone holding bitcoin would have watched the market with alarm in recent weeks. The virtual currency, whose price other cryptocurrencies like ethereum and litecoin largely follow, plummeted from more than US$10,000 (£8,206) in mid-February to briefly below US$4,000 on March 13. Despite recovering to the mid-US$6,000s at the time of writin...
