Context:
Humans from the Clovis culture used characteristic
stone points (brown) and rod-shaped bone tools.
The remains of a young boy, ceremonially buried some 12,600 years ago in Montana, have revealed the ancestry of one of the earliest populations in the Americas, known as the Clovis culture.
Published in this issue of
Nature, the boy’s genome sequence shows that today’s indigenous groups spanning North and South America are all descended from a single population that trekked across the Bering land bridge from Asia (
M. Rasmussen et al. Nature 506, 225–229; 2014). The analysis also points to an early split between the ancestors of the Clovis people and a second group, whose DNA lives on in populations in Canada and Greenland (see
