First Americans Lived on Bering Land Bridge for Thousands of Years - Scientific American

First Americans Lived on Bering Land Bridge for Thousands of Years - Scientific American | The origin of Native Americans | Scoop.it
Genetic evidence supports a theory that ancestors of Native Americans lived for 15,000 years on the Bering Land Bridge between Asia and North America until the last ice age ended
Jeffrey Kromer's insight:

Evidence shows that humans left Siberia around 30,000 years ago and did not appear in North America until 15,000 years ago. This suggest that humans stayed on the "Land Bridge" for nearly 15,000 years. This article goes into depth about where the Native Americans were for 15,000 years. It was written by Scott Armstrong Elias and published by The Conversation.

Native Americans migrated to the New World in three waves, Harvard-led DNA analysis shows

Native Americans migrated to the New World in three waves, Harvard-led DNA analysis shows | The origin of Native Americans | Scoop.it
An exhaustive study of DNA taken from dozens of Native American groups is helping to settle a question that has long divided scientists: When people arrived in the Americas more than 15,000 years ago, the Harvard-led research shows, they came in successive waves, not all at once. The analysis published Wednesday reveals that while one population of “First Americans” crossed a land bridge from Siberia, giving rise to most Native Americans, there were at least two other migrations.
Jeffrey Kromer's insight:

To do this research, Scientists looked at multiple spots in the genome of all of the people, where it is common for the DNA to differ. They used the information gathered from this research to show which groups stayed together and which split up. This article goes into depth about when certain groups got to the Americas and how they got there and was written by Carolyn Y. Johnson and published on boston.com.

Other Migration Theories
Jeffrey Kromer's insight:

From 2008 on, evidence has shown that a group of present-day humans migrated to North America from Siberia using a "Land Bridge". However, this was not the only Migration. This article goes into depth about recent findings and other migration theories. It was published on nps.gov.

"Great Surprise"—Native Americans Have West Eurasian Origins - National Geographic

"Great Surprise"—Native Americans Have West Eurasian Origins - National Geographic | The origin of Native Americans | Scoop.it
Nearly one-third of Native American genes come from west Eurasian peoples with ties to the Middle East and Europe, according to the oldest human genome yet sequenced, a new study says.
Jeffrey Kromer's insight:

The bone of a 24,000 year old Siberian has generated the oldest genome of present-day humans ever. The DNA had shown several characteristics unique to Native Americans. This article goes into depth about the ancestry of the first people of the Americas and was written by Brian Handwerk and published by National Geographic.
