There are now several examples of modifications of an individual’s appearance and behavior by the environment, and of those modifications affecting the individual’s genes, usually by attaching methyl bases to specific nucleotides in the DNA sequence. This is a form of environmentally induced epigenetic modification.
SAN BERNARDINO – In a tiny cemetery that serves as the final stop for hundreds of once-destitute people, college students are spending another summer trying to solve the mysteries of anonymous death in a hectic world.
The basic goal is simple – to connect names to bodies.
(CNN) —Since the days when George Washington was enamored with Sally Fairfax, presidents have contended with rumors of extramarital affairs, but without proof, the shadow of a doubt has worked in their favor.
Then along came DNA testing. It has tossed uncertainty out the window, most recently with the help of a former president’s grandniece who spoke to CNN’s “New Day” on Friday.
Images of skeletons from the Lajia site in the Qinghai province of China are captivating. Painstaking excavation and pedestaling of the bones reveals adults and children in a 4,000-year-old embrace. But while these images have gotten media attention today, the archaeological site has been excavated since 1999 by archaeologists primarily from the Institute of Archaeology at the Chinese Academy of Social Sciences and the Qinghai Provincial Institute of Antiquity and Archaeology.
Ancestral humans carried 40.7 million more DNA base pairs than people do today, researchers report online August 6 in Science. That’s enough DNA to build a small chromosome, says study coauthor Evan Eichler, an evolutionary geneticist at the University of Washington in Seattle.
SEOUL, South Korea — Amid a backlog of requests from aging war survivors, the Korean Red Cross is dramatically expanding its collection of genetic material from South Koreans separated from their families during the Korean War.
Genetic studies of living Native Americans and ancient remains are revising our theories about America’s first inhabitants.
In a letter sent to the U.S. Army Corps of Engineers on June 23 Washington Governor Jay Inslee requested that the remains of The Ancient One, or Kennewick Man, be turned over to Native American tribes.
NEW YORK — An ancient skeleton found nearly 20 years ago in a river in Washington is related to Native Americans, says a DNA study that could help resolve a long-running dispute over its ancestry and custody.
Valognes (France) (AFP) – British researchers on Monday began collecting the DNA of residents from Normandy in northern France in search of Viking heritage, but the project has raised concerns amongst some local anti-racism activists.
For centuries, archaeologists have reconstructed the early history of Europe by digging up ancient settlements and examining the items that their inhabitants left behind. More recently, researchers have been scrutinizing something even more revealing than pots, chariots and swords: DNA.
Genes from 5,000 years ago show that the Europeans of that crucial historical era were predominantly light-skinned — and mostly lactose-intolerant.
The findings, based on a rough analysis of genetic material extracted from the teeth of 101 ancient humans, provide snapshots of how mass migrations changed Europe’s peoples during the Bronze Age, which lasted from around the year 3000 B.C. to 1000 B.C.
Revolutionary new methods for extracting, purifying, and sequencing ever-more-ancient DNA have opened an unprecedented window into the history of life on Earth.
Scientists in India will compare DNA from the bones of six 700-year-old skeletons to the DNA of living descendants of the Ahom royals to see if the old bones belong to the ancestors of the Ahom royal family or to looters who died while plundering the tombs at the famous Charaideo Maidam site in Assam, the burial site of kings and queens of the Ahom kingdom.
Skeletons from Peru caves plot course for a single migration to the continent.
