Mystery of Native Americans’ arrival

first_imgThe Americas’ first human settlers arrived in a complex series of migrations, pushing over the ancient land bridge from Asia at least three times but moving in both directions, with at least one group scrapping it all and bringing themselves and their genetic signature back home to Asia.Research conducted by an international team led by scientists from Harvard University and University College London illuminates the roots of today’s Native Americans through genetic analysis and by comparison with native groups in Siberia.The results, published in the July 11 issue of the journal Nature, examined genetic data from 52 Native American groups and 17 Siberian groups, and helped settle a debate among anthropologists over whether the Americas were settled just once or several times.The results not only show that multiple waves of settlers arrived on the continents’ shores from Asia, but that some groups reversed direction. In addition to those that headed home to Asia, another that made it to South America migrated back north to Central America.The work made no findings about the timing of settlement, but prior research indicates that the first humans reached North America some 15,000 years ago when the massive glaciers of the last ice age locked up enough water to lower sea levels and expose a 1,000-mile-wide land bridge between Siberia and Alaska.The current research, led by David Reich, professor of genetics at Harvard Medical School, and by Andres Ruiz-Linares of University College London, shows that the majority of the genetic signature of today’s Native Americans comes from an initial migration during which people, termed “First Americans” by the researchers, pushed south along the Pacific Coast from Alaska to the tip of South America.The second migration was smaller geographically but had a large impact on the native people of the far north. Today’s Aleut-Inuit populations owe about half of their genetic background to this second migration.The third migration contributed about 10 percent of the genetic background of Canada’s Chipewyan people, concentrated today around Hudson Bay.“The Americas are, of course, an important region of the world,” said Reich. “The native peoples of America have a fascinating and contentious history. It’s very important to understand how people first got here and how people dispersed within the Americas.”The return of some Native Americans to Asia was revealed only as researchers struggled to understand their data, Reich said. Early results clearly indicated the migration of First Americans along the coast to South America, but the results for North America were more complex. As researchers struggled to decipher the data, they traced their confusion to a false assumption: that the DNA signature from Asia was purely ancestral and contained no later recombination with Native American genes.Once they took that possibility into consideration, it became clear there had been at least three migrations from Asia to America and at least one back to Asia, contributing Native American genes to the Naukan and Chukchi people of northeastern Siberia.The four-year study involved 64 researchers from institutions around the world. Key to the work, Reich said, was access to genetic information on native peoples collected over many years by senior author Ruiz-Linares.In conducting the research, scientists studied more than 300,000 genetic changes called single-nucleotide polymorphisms, which are isolated changes in the molecules that make up DNA’s long, twisting structure.The work was further complicated by multiple genetic changes in native peoples since 1492, when the continents’ conquest and settlement by Europeans began, followed by the arrival of African slaves and of later immigrants. Using techniques refined in earlier research, Reich said researchers were able to isolate and study portions of the genome known to be of Native American origin.Though the research has settled one important question, the work is far from done, Reich said. Further investigation, particularly of native people of northern North America where sampling was thin, can further enrich the picture of the hemisphere’s original inhabitants.“No picture of human history is complete. The harder you look at it, the more there is to find,” Reich said. “What we’ve shown is that there were at least three streams of gene flow from Asia, but there could easily — perhaps are likely to have been — more. There’s just some that we can’t detect.”last_img read more

‘Lawyers Caught in Jury Tampering Will Be Jailed’

first_img— Judge Nancy Sammy threatensIn her efforts to regain public confidence in the Judicial Branch, the assigned Criminal Court ‘C’ Judge Nancy Sammy has threatened to imprison any lawyer that would contact a potential juror and attempt to influence the juror’s thoughts about how a case before her should end.Judge Sammy’s strongly worded statement comes in the face of public concern that most of the cases tried by jury at that court have usually ended at the Supreme Court as a result of alleged jury tampering, an accusation which has created a dark cloud over the image of the country’s justice system.Jury tampering, a legal expert explained to the Daily Observer,  is the crime of attempting to influence a jury through other means than the evidence presented in court, such as conversations about the case outside the court, offering bribes, making threats or asking acquaintances to interfere with a juror.“A person commits the crime of jury tampering if, with intent to influence a juror’s vote, opinion, decision or other action in the case, he attempts directly or indirectly to communicate with a juror other than as part of the proceedings in the trial of the case,” the expert noted.However, Judge Sammy, who is the first female to preside over the Criminal Court ‘C’ warned that lawyers who will be practicing before her court, Criminal Court ‘C’, should be mindful that she would not tolerate any attempt at jury tampering.The criminal court judge further warned that “if any of you lawyers engage in jury tempering and you are caught, be assured that you will not go scot-free”, she added, “because we will ensure that you be drastically dealt with in conformity with the law, so be warned.”The Criminal Court ‘C’ is one of the courts that has been plagued with charges of  jury tampering and where the Supreme Court has been constrained to disband those jurors based on jury tampering.One of the cases is that which involved former Managing Director of the National Port Authority (NPA), Matilda Parker and her Comptroller Christina Paelay, in which Associate Justice Jamesetta Wolokolie, then Chamber Justice, was constrained to disband the jury due to accusation of jury tampering.In that case, the government lawyers charged that jurors in the case were tampered with, following the discovery of a letter that was addressed to two of the sequestrated jurors, Melvin Neowan and Kebbeh Kollie. The two jurors denied the allegation.However, Parker and Paelay managed to win the charges against them due to government’s continued failure to try the matter.It is against this backdrop that Judge Sammy vowed not to tolerate any attempt of jury tampering by lawyers practicing before her court.Judge Sammy highlighted these concerns when she recently delivered her charge during the opening of the November 2019 Term of Criminal Courts, A, B, C and D for Montserrado County.During her deliberation, Judge Sammy said: “Some politicians might try to use our courts as platforms to promote themselves by interfering in judicial decisions, and so you have to take judicial notice of that fact.”Judge Sammy reminded her colleagues that they should not allow themselves to be pressured, coerced, or to let their courts to be used as a platform by politicians to promote themselves, stressing, “Please do not allow any politician to interfere in judicial decisions you will make.”However, she said that if cases are brought before them as judges that would cause conflict of interest, then in such situation, she advised, “the most appropriate thing to do is to recuse yourself as a sitting judge from hearing such cases.”She said that it is important to do so, “because as dispensers of justice, we cannot allow ourselves to be caught in situations that would embarrass us and the entire judiciary.”The female judge (Sammy) then noted that though she and others are relatively new to the judgeship, “a core value we have upheld is to resist outside influence, and to be prompt and expeditious in handling matters that come  before us.”In a nutshell, she maintained, “we shall work diligently during this term to ensure that the law takes its course in clear, precision-driven terms and in a fearless manner.”Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) – Advertisement – Criminal Court ‘C’ Judge Judge Nancy Sammy last_img read more

Whittier council raises fence height for homeowners along Greenway Trail

first_imgWHITTIER – The City Council has agreed to allow homeowners along the Greenway Trail taller fences as a way of providing more privacy and making up for the trees chopped down in some areas 13 months ago. The council voted 4-1 Tuesday to approve the first reading of the ordinance that raises the maximum height from 8 to 10 feet. “This is another opportunity to help residents along the trail,” Councilman Joe Vinatieri said. “We will have people going east and west all times of the day. We will have a lot more looky-loos looking into the back yard than before.” The problem is that the 4.5-mile long trail is at a higher grade than homes in some areas. And to make it worse, trees, which provided privacy for some homeowners near Palm Park, were cut down in September 2006. 165Let’s talk business.Catch up on the business news closest to you with our daily newsletter.
