Staff Report

Two historic shipwreck sites could be designated as National Marine Sanctuaries under a proposal outlined by President Barack Obama at an international ocean conference today.

In a press release, the National Oceanic and Atmospheric Administration said it’s the first time since 2000 that the agency has identified new sites for that designation. NOAA is taking public comment on the proposal. Continue reading

Study finds evidence of prehistoric salmon fishing in Alaska

‘We now know that salmon have been consumed by North American humans at least 11,500 years ago …’

Staff Report

Digging deep into the remains of an ancient kitchen, archaeologists say that early residents of North America likely fished for salmon starting at the end of the last ice age, just as they started colonizing the continent.

The study, published this week in the Proceedings of the National Academy of Sciences, is the earliest known evidence that Ice Age humans in North America used salmon as a food source and shows that those settlers were not just big game hunters. Continue reading

Study sheds light on earliest migrations of Native Americans


New study confirms Bering Land Bridge migration theory.

Northern and southern Native American populations diverged between 11,500 and 14,500 years ago …

Staff Report

FRISCO — Scientists say they’re a lot closer to pinpointing how and when the first Native Americans came to the Americas, and how they spread across two continents.

The findings came from a detailed analysis of genetic material from 31 living Native Americans, Siberians and people from around the Pacific Ocean, and the genomes of 23 ancient individuals from North and South America, spanning a time between 200 and 6,000 years ago. Continue reading

Conservation groups seek ban on new fracking around Chaco Canyon

More fracking threatens public health, historic treasures

Staff Report

FRISCO — Oil and gas drilling in the vicinity of the treasured Chaco Culture National Historical Park poses an imminent risk to irreplaceable resources, conservation groups said as the moved to block the federal government from approving any more permits.

Continued drilling threatens public health, clean air and water, and Navajo communities in the region, the groups said as they called on a federal judge to issue an injunction on oil and gas development in the Greater Chaco region. Continue reading

Findings may require re-evaluation of how the Americas were colonized by humans

Staff Report

FRISCO — Thor Heyerdahl’s 1947 Kon-Tiki voyage showed that people could have sailed from South America to the South Pacific islands even without modern instrumentation, and now, a new genetic study shows that it might have been a two way street.

Genomic evidence suggests that people may have been traveling from Easter Island to the Americas long before European explorers arrived at the remote oceanic outpost, and that they had significant contact with Native American populations, as early as 1300 AD.

Along with establishing genetic links, the study suggests that historians and anthropologists might need to take a fresh look at some of their most basic ideas about how humans spread around the globe. Continue reading

Archaeology: Tracking Buddha’s birthday

New research in Nepal may help pinpoint origins of Buddhism

Staff Report

FRISCO — A well-known historical site in Nepal may gain even more significance after archeologists found evidence linking the site of the temple with the birth of Buddha in the sixth century B.C.

Most historical records link Buddhism’s origins with the fifth or sixth century B.C. But according to the researchers working at this site, their findings are the first to link the life of Buddha with a specific century.

The excavations were conducted at the sacred Maya Devi Temple at Lumbini, Nepal, a UNESCO World Heritage site long identified as the birthplace of the Buddha. As the archaeologists dug deeper, they found the remains of a previously unknown sixth-century B.C. timber structure under a series of brick temples. Laid out on the same design as those above it, the timber structure contains an open space in the center that links to the nativity story of the Buddha himself. Continue reading

Study sheds new light on ancestral human movement patterns leading to colonization of the Mediterranean region

By Summit Voice

FRISCO — Scientists have long speculated that humans migrated across the Sahara region of Africa to populate the Mediterranean region, but the exact movement corridor has remained a mystery.

A new study, led by researchers with the University of Hull, shows there may have been three ancient river systems that created a viable route about 100,000 years ago. Continue reading
