A professor and his team are excavating a burial site at the Upward Sun River in central Alaska. Painstakingly removing soil, they come across something striking: the remains of two infants. Since this site dates back 11,500 years, they’re looking at human skeletons from the earliest North American settlers. And as it turns out, these tiny bones hold a stunning secret about America’s past.
Now, the two sets of bones, which were uncovered in 2013, come from a baby who died around six to 12 weeks after birth, and an infant who was apparently still-born. And it seems the two children were buried together. In fact, these two sets of remains likely belonged to girls who were cousins. Furthermore, they were only discovered after another infant’s remains were found back in 2010.
