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…

Update (1100ET): At long last, Buzzfeed is finally going public, a crowning career accomplishment for founder and CEO Jonah Peretti.

As we reported earlier, Peretti confirmed on Thursday morning that Buzzfeed had agreed to merge with the obscure 890 5th Avenue Partners (yes, it's named after the fictional headquarters of the Avengers), which raised $250 million in an IPO earlier this year.

The SPAC is led by CEO Emiliano Calemzuk and executive chairman Adam Rothstein, and counts NBCUniversal ad sale chief Linda YAccarino, former Buzzfeed President Greg Coleman, Time W...

Will Bitcoin Crash the Stock Market?

When the S&P 500 fell in March last year, it brought Bitcoin down with it. So if stocks can bring down Bitcoin, it’s reasonable to ask if Bitcoin can bring down stocks.*

If you thought the Bitcoin run-up to 60k was emblematic of investor** euphoria, then you probably wondered what would happen if it were to come crashing down. Would that take other high-flying areas of the market down with it?

It might be premature, but as of now, the answer is no.

Crude Oil Cleared For Blast Off On This Dual Breakout?

Courtesy of Chris Kimble

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

The Suez Canal: A Critical Waterway Comes to a Halt

On March 23, 2021, a massive ship named Ever Given became lodged in the Suez Canal, completely blocking traffic in both directions. According to the Suez Canal Authority, the 1,312 foot long (400 m) container ship ran aground during a sandstorm that caused low visibility, impacting the ship’s navigation. The vessel is owned by Taiwanese shipping firm, Evergreen Marine.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
