Some Amazonian Native Americans descend partly from a Native American founding population that carried ancestry more closely related to indigenous Australians, New Guineans and Andaman Islanders than to any present-day Eurasians or Native Americans. This signature is not present to the same extent, or at all, in present-day Northern and Central Americans or in a 12,600-year-old Clovis-associated genome, suggesting a more diverse set of founding populations of the Americans than previously accepted.
[Quoting Pontus Skoglund]

The entire pre-Columbian literature of Mexico, a vast library of tens of thousands of codices, was carefully and systematically destroyed by the priests and friars who followed in the wake of the conquistadors. In November 1530, for example, Bishop Juan de Zumárraga, who had shortly before been apointed 'Protector of the Indians' by the Spanish crown, proceeded to 'protect' his flock by burning at the stake a Mexican aristocrat, the lord of the city of Texcoco, whom he accused of having worshipped the rain god. In the city's marketplace Zumárraga 'had a pyramid formed of the documents of Aztec history, knowledge and literature, their paintings, manuscripts, and hieroglyphic writings, all of which he committed to the flames while the natives cried and prayed.'
More than 30 years later, the holocaust of documents was still under way. In July 1562, in the main square of Mani (just south of modern Merida in the Yucatan), Bishop Diego de Landa burned thousands of Maya codices, story paintings, and hieroglyphs inscribed on rolled-up deer skins. He boasted of destroying countless 'idols' and 'altars,' all of which he described as 'works of the devil, designed by the evil one to delude the Indians and to prevent them from accepting Christianity.' Noting that the Maya 'used certain characters or letters, which they wrote in their books about the antiquities and their sciences' he informs us: 'We found a great number of books in these letters, and since they contained nothing but superstitions and falsehoods of the devil we burned them all, which they took most grievously and which gave them great pain.

The same solution — that Easter Island was once part of a much larger landmass — would also explain another, very different puzzle, namely the so-called Rongo Rongo script. It is unprecedented in human history for a sophisticated fully developed writing system to be invented and put into use by a small, isolated island community. Yet Easter Island does have its own script, examples of which, mostly incised on wooden boards, copies of copies of copies of much older lost originals, were collected in the nineteenth century and have found their way into a number of museums around the world. None remain on Easter Island itself and even in the period when they were collected no native Easter Islanders were able to read them.
