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…

Why Genes Aren’t Destiny

TIME photoBy John Cloud, courtesy of TIME

The remote, snow-swept expanses of northern Sweden are an unlikely place to begin a story about cutting-edge genetic science. The kingdom’s northernmost county, Norrbotten, is nearly free of human life; an average of just six people live in each square mile. And yet this tiny population can reveal a lot about how genes work in our everyday lives.

Norrbotten is so isolated that in the 19th century, if the harvest was bad, people starved. The starving years were all the crueler for their unpredictability. For instance, 1800, 1812, 1821, 1836 and 1856 were years of total crop failure and extreme suffering. But in 1801, 1822, 1828, 1844 and 1863, the land spilled forth such abundance that the same people who had gone hungry in previous winters were able to gorge themselves for months.

In the 1980s, Dr. Lars Olov Bygren, a preventive-health specialist who is now at the prestigious Karolinska Institute in Stockholm, began to wonder what long-term effects the feast and famine years might have had on children growing up in Norrbotten in the 19th century — and not just on them but on their kids and grandkids as well. So he drew a random sample of 99 individuals born in the Overkalix parish of Norrbotten in 1905 and used historical records to trace their parents and grandparents back to birth. By analyzing meticulous agricultural records, Bygren and two colleagues determined how much food had been available to the parents and grandparents when they were young.

Around the time he started collecting the data, Bygren had become fascinated with research showing that conditions in the womb could affect your health not only when you were a fetus but well into adulthood. In 1986, for example, the Lancet published the first of two groundbreaking papers showing that if a pregnant woman ate poorly, her child would be at significantly higher than average risk for cardiovascular disease as an adult. Bygren wondered whether that effect could start even before pregnancy: Could parents’ experiences early in their lives somehow change the traits they passed to their offspring?

It was a heretical idea. After all, we have had a long-standing deal with biology:…

American Express bulls play calendar spread

Today’s tickers: AXP, JNPR, GE, XLF, JPM, WFC, DNA, COP & XOM

AXP – American Express Company – Shares of the global payments and travel company have rallied by 7% to $11.83, an upward move which is likely due to the news that AXP’s fourth quarter earnings were favorably revised yesterday because of an accounting error. Adjustments boosted earnings per share to 21 cents from the previously recorded 15 cents for the quarter, and net income for the year amounted to $2.7 billion up from $2.63 billion originally. Option traders welcomed the unexpected news and established bullish positions on AXP today. One indication of bullishness was the rash of put selling in the March contract. March 10 and 12.5 strikes were heavily sold. Juxtaposed with the near-term bullishness observed is one far-term optimist on AXP, who sees shares doubling by January 2011. In the January 2010 contract at the 20 strike price 10,000 calls were sold for 95 cents each. Using the 20 strike price in January 2011, 10,000 calls were purchased for 1.95 apiece. For this calendar spread to come good, shares would need to nearly double from the current level. We have to think that this spread is already or will be coupled with underlying stock with the risk that the investor is left deficient of shares in the event of a break through $20.00 ahead of expiration.

JNPR – Juniper Networks Inc. – Shares have remained relatively flat today, having fallen just 0.15% to $13.46. The assured and secure Internet Protocol networking solutions company caught our attention due to its high call-to-put ratio which is currently favoring calls 11 times to every single put in play. But, the majority of the calls traded today were sold, indicated an overall bearish picture of the stock. At the March 13 strike price, 3,300 in-the-money calls were sold for 88 cents apiece – perhaps profit taking by investors exiting existing positions at that strike. At the March 14 strike 3,500 calls were shed for 42 cents apiece. The same trend was observed in the April contract where the April 12 strike price had 4,000 calls sold for 1.96, the 13 strike price saw the sale of over 5,100 calls for a premium of 1.28, and the 14 strike had more than 3,600 calls sold for 80 cents per contract. Implied volatility has come off since yesterday reading of 60% to…

Trash Wars: Duterte Orders Tons Of Garbage Shipped Back To Canada Or Dumped In Territorial Waters

Outspoken Philippines President Rodrigo Duterte has ordered that containers carrying trash from Canada should be shipped back to the country. It is the latest chapter in a disagreement over more than 100 containers of trash that were shipped to the Philippines between 2013 and 2014, illegally, by a Canadian company. 

Canada had previously agreed to take the trash back, but has been slow in making arrangements for its return. Duterte threatened to leave the trash in Canadian waters if Ottawa refuses to take it back, according to Salvador Panelo, spokesman for the President. Quoted by RT, Panelo said Duterte was “upset” by Ot...

DAX (Germany) About To Send A Bearish Message To The S&P 500?

Is the DAX index from Germany about to send a bearish message to stocks in Europe and the States? Sure could!

This chart looks at the DAX over the past 9-years. It’s spent the majority of the past 8-years inside of rising channel (1), creating a series of higher lows and higher highs.

It looks to have created a “Double Top” as it was kissing the underside of the rising channel last year at (2).

After creating the potential double top, the DAX index has continued to create a series of lower highs, while experiencing a bearish divergence with the S...

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
