Donner Party were American pioneers who became snowbound in the 19th century in the Sierra Nevada. It's been said by researchers, scientists, and archeologists that the Donner Party resorted to cannibalism to survive, and according to their personal journals, this was evident from the writings.
"27th.--Still in camp; no fire; Patrick Dolin died.""On the twenty-seventh they took the flesh from the bodies of the dead; and on that, and the two following days they remained in camp drying the meat, and preparing to pursue their journey."
"29th.--Nor food for five days; a portion of the company eat human flesh. "
Now, however, a biological anthropologist at Appalachian State University, and her team produced thin sections from the hearth bones and examined them under high magnification in order to measure each basic structural unit and link the bones to particular animals.
"What we have demonstrated is that there is no evidence for cannibalism," said Robbins. "If the Donner Party did resort to cannibalism, the bones were treated in a different way (such as buried), or they were placed on the hearth last and could have since eroded."
