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…

Are Commodities Sending Global Macro Message To Investors?

Courtesy of Chris Kimble.

Commodities are becoming a hot topic… and an important investing theme. With the US Dollar coming back to life, commodities have pulled back. And that pullback now has the “equal weight” complex in trouble.

Below is a chart of the Thomson Reuters Equal Weight Commodity Index. The green shaded area represents a 20-year rising channel (point 1).  Within that channel, however, commodities have formed a multi-year downtrend (point 2 – marked in red).

Using the all-time high and the early 2016 low, we can identify key Fibonacci levels. One level is the 23.6% Fib, which proved to be stiff resistance (point 3), marking a bearish reversal as well.

Currently, the Commodity Index is attempting to break 20-year channel support (point 4).

Investors should watch for ...

It has been soundly demonstrated that the President of the United States has a knowledge vacuum in proper presidential decorum, diplomacy, and accepted norms of behavior.

Tesla's Board Throws Elon Musk Under The Bus

One of the key questions to emerge from Elon Musk's going private "funding secured" fiasco, is where was the board before, during and after the series of torrid tweets sent out by the Tesla CEO in the past two weeks.  In an overnight NYT article, we finally get a fairly clear picture of what was going on through the heads of the company's board of directors, and it's not pretty.

While we urge readers to skim the full piece here, below ...

There Are 3 Main Theories That Explain Trump's Approach to Putin and Russia-Which One Makes the Most Sense?

Thom Hartmann suggests that the "Manchurian Candidate theory" is the least likely explanation for Trump's pro-Russia behavior in "There Are 3 Main Theories That Explain Trump’s Approach to Putin and Russia—Which One Makes the Most Sense?"

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
