A pair of baby skeletons in Alaska are more than 11,500 years old and offer new hints about the death rituals of early people in North America, researchers said Monday. The bodies “represent the earliest known human remains from the North American subarctic,” said the study in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal. The infants were found buried 15 inches (40 centimeters) beneath another child’s cremated remains, in a circular pit that also held spear points with decorated antler shafts. An analysis of bones and teeth at the Upward Sun River site in central Alaska revealed that one died shortly after birth and the other was a late-term fetus, researchers from the University of Alaska,
