Ancient DNA Linked To Living Descendants In Genetic Study

What if you could trace your ancestry back to around 5,000 years ago? Researchers were able to do just that in a fascinating new DNA study, which found adirect genetic link between the ancient remains of Native Americans and their living relatives.

“It’s very exciting to be able to have¬†scientific proof that corroborates what our ancestors¬†have been telling us for generations,”¬†study co-author and participant Joycelynn Mitchell¬†said in a written statement. “It’s very amazing how fast technology is moving to be able to prove this kind of link with our past.”

In the study, U.S. and Canadian researchers used mitochondrial genome (mitogenome) sequencing to analyze DNA inherited exclusively through mothers. Looking at the mitogenome is cheap, easier to sequence than nuclear DNA, and skirts around the problem that European men mixed with Native American women.

The researchers collected¬†DNA from 60 living indigenous people¬†belonging to the Tsimshian, Haida and Nisga’a tribes in the northern coast of British Columbia. The tribes’ oral histories and archaeological sites indicate they have lived in the region for generations, which made them good candidates for tracing their lineage back so many years.

Complete mitogenomes were extracted from the remains of four¬†Mid-Holocene individuals¬†found in British Columbia’s Lucy Islands and Dodge Island, and then that information was compared to the DNA of the study participants.

What was found? The research team discovered one of the living individuals carried this same “mitogenomic signature” as a young adult female who lived on Dodge Island 2,500 years ago — which also matched the mitogenome of the remains of a woman who lived in the Lucy Islands 5,500 years ago. Wow.

Three other living participants had mitogenomes that linked back to the remains of another individual found on Dodge Island, who may have lived around 5,000 years ago.

‚ÄúThis is the beginning of the golden era for ancient DNA research because we can do so much now that we couldn’t do a few years ago because of advances in sequencing technologies,‚ÄĚ study co-author¬†Dr. Ripan Malhi, an anthropology professor¬†at the University of Illinois and Institute for Genomic Biology professor, said in a written statement. ‚ÄúWe‚Äôre just starting to get an idea of the mitogenomic diversity in the Americas, in the living individuals as well as the ancient individuals.‚ÄĚ

The new study was published online on June 3, 2013 in the journal PLoSONE.

Kuwait has Highest BMI in the World

From the Daily Mail (UK)

The countries which contain the heaviest and lightest citizens can be revealed today.

This extraordinary graphic shows the average body mass index values for adults around the globe – with some surprising results.

With its wealthy society and love of fast food outlets, many would place the U.S. at the top of the list.

But it is pipped to first place in the body mass index chart by Kuwait. The Arab state has an average body mass index of 27.5 for men and 31.4 for women.

This beats America in second place which averages 26.5 for men and 29 for women.

From UPI:

Mexico is world fattest nation, United States No. 2

UNITED NATIONS, July 10 (UPI) —¬†Officials at the U.N. Food and Agricultural Organization say Mexico with a 32.8 percent adult obesity rate is the most overweight of the industrialized nations.

Previously, the United States with an adult obesity rate of 31.8 percent was the world’s fattest nation. Last year, the percentage of U.S. adults overweight went down slightly.

A report by the FAO said Mexico’s widely available inexpensive junk food and penetration of U.S. fast-food chains combined with a more sedentary lifestyle all contributed to Mexico’s bulging waistline.

About 70 percent of Mexican adults are overweight, while childhood obesity tripled in a decade and about a third of teenagers are overweight as well, the Global Post said.

Weight-related diabetes claims 1-of-6 one of Mexican adults — or 70,000 people a year — suffering from the disease each year, the report said.
