Tiny footprints, big discovery: Reptile tracks oldest ever found in Grand Canyon

Geologists have discovered that a set of 28 footprints left behind by a reptile-like creature 310 million years ago are the oldest ever to be found in Grand Canyon National Park.


Ancient DNA evidence reveals two unknown migrations from North to South America

A team has used genome-wide ancient DNA data to revise Central and South American history. Their analysis of DNA from 49 individuals spanning about 10,000 years in Belize, Brazil, the Central Andes, and southern South America has concluded that the majority of Central and South American ancestry arrived from at least three different streams of people entering from North America, all arising from one ancestral lineage of migrants who crossed the Bering Strait.


History of early settlement and survival in Andean highlands revealed by ancient genomes

A multi-center study of the genetic remains of people who settled thousands of years ago in the Andes Mountains of South America reveals a complex picture of human adaptation from early settlement, to a split about 9,000 years ago between high and lowland populations, to the devastating exposure to European disease in the 16th-century colonial period.


DNA of world's oldest natural mummy unlocks secrets of Ice Age tribes in the Americas

A wide ranging international study that genetically analysed the DNA of a series of famous and controversial ancient remains across North and South America has discovered that the Spirit Cave remains -- the world's oldest natural mummy - was a Native American. They were also able to dismiss a longstanding theory that a group called Paleoamericans existed in North America before Native Americans.


Ancient child's tooth reveals picture of Alaska's early inhabitants

Research on a newly rediscovered 9,000-year-old child's tooth has reshaped our understanding of Alaska's ancient people, their genetic background and their diets. The tooth is only the second known remnant of a population of early migrants known as Ancient Beringians. Combined with previous research, the find indicates that Ancient Beringians remained in Alaska for thousands of years after first migrating across the Bering Land Bridge that connected eastern Asia and Alaska.
