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…

JPMorgan: Please Buy This Dip

After JPMorgan clocked in its most profitable year in history in 2019 largely on the back of the Fed's QE4 which - as we remind readers again - was triggered by JPMorgan itself, which sparked a repo market crisis after yanking money market and repo liquidity forcing the Fed to first launch repos and then T-Bill purchases, the bank is not only convinced that the good times will continue to roll after the most powerful market meltup in history in the past 4 months, but that the current melt down on the back of fears over a global viral pandemic, is overdone and will end soon, presenting its clients with another delightful opportunity to BTFD. ...

Retail investors are last in line for market leading research, no matter, the retail investor can profit from these secret sauce patterns..

Well not so secret now, the main point is you do not have to climb Mount Everest to be called a mountain climber, there are many other hills to climb to make your mark. Just like stocks.

You do not have to battle with the high frequency traders to win in the markets, there are long and slow methods to do just as well.

The Wuhan Wipeout - Could It Happen?

News is traveling fast about the Corona Virus that originated in Wuhan, China. Two new confirmed cases in the US, one in Europe and hundreds in China. As we learn more about thispotential pandemic outbreak, we are learning that China did very little to contain this problem from the start. Now, quarantining two cities and trying to control the potential
outbreak, may become a futile effort.

In most of Asia, the Chinese New Year is already in full swing.  Hong Kong, China, Singapore, Malaysia, India and a host of other countries are already starting to celebrate the 7 to 10 day long New Year.  Millions of people have already traveled hundreds of thousands of miles to visit family...

Bad News For Crude Oil Should Come From This Pattern, Says Joe Friday

It’s a good idea for investors to be aware of key indicators and inter-market relationships.

Perhaps it’s watching the US Dollar as an indicator for precious metals or emerging markets. Or watching interest rates for the economy. Experience, history, and relationships matter. And it’s good to simply add these to our tool-kit.

Today, we look at another relationship that has signaled numerous stock market tops and bottoms over the years, and especially the past several months, Crude Oil.

When crude oil tops or bottoms, it seems that ...
