Where Science Meets Society

For First Nations peoples, effects of European contact recorded in genome

A study of the genomes of 25 individuals who lived 1,000 to 6,000 years ago on the north coast of present-day British Columbia, and 25 of their descendants who still live in the region today, opens a new window on the catastrophic consequences of European colonization for indigenous peoples in that part of the world.

The study is reported in the journal Nature Communications.

Genomes Tell Story of Native American Biological Origins

The first human inhabitants of the Americas lived in a time thousands of years before the first written records, and the story of their transcontinental migration is the subject of ongoing debate and active research.  A study by multi-institutional, international collaboration of researchers, published this week in Science (DOI: 10.1126/science.aab3884) presents strong evidence, gleaned from ancient and modern DNA samples, that the ancestry of all Native Americans can be traced

Monkey Droppings Complement Field Observations, Researchers Report

In South American rainforests, researchers can tell one saddle-back tamarin from another, but what’s more difficult, is to see what the squirrel-sized monkeys are putting in their mouths. Researchers are beginning to rely on their droppings to find out what bugs and other invertebrates the monkeys munch on. 

Genetic study resolves speculation about first people in Americas

Genetic study helps resolve years of speculation about first people in the Americas

A new study could help resolve a longstanding debate about the origins of the first people to inhabit the Americas, researchers report in the journal Science. The study relies on genetic information extracted from the tooth of an adolescent girl who fell into a sinkhole in the Yucatan 12,000 to 13,000 years ago.
