"The human found with the megafauna remains in Hoyo Negro could represent the oldest evidence of humans yet discovered in the Americas.
Archaeological and genetic data have long supported a northeast Asia origin for the populations that first settled North and South America. The so-called "First Americans" or Paleoindian peoples likely entered into these new lands sometime between 15,000 and 20,000 years ago.
Although a number of early archaeological sites have been excavated, only few sets of Paleoindian remains have been found. A detailed analysis of the human skeletal remains from Hoyo Negro can help us to better understand who these First Americans were and when they arrived here, which is one of the greatest mysteries in American archaeology."
