Basically, one word: WOW.

"“About 2 percent of the ancestry of Amazonians today comes from this Australasian lineage that’s not present in the same way elsewhere in the Americas,” said Reich.

However, that doesn’t establish how much of their ancestry comes from Population Y. If Population Y were 100 percent Australasian, that would indeed mean they contributed 2 percent of the DNA of today’s Amazonians. But if Population Y mixed with other groups such as the First Americans before they reached the Americas, the amount of DNA they contributed to today’s Amazonians could be much higher—up to 85 percent.

To answer that question, researchers would need to sample DNA from the remains of a person who belonged to Population Y. Such DNA hasn’t been obtained yet. One place to look might be in the skeletons of early Native Americans whose skulls some researchers say have Australasian features. The majority of these skeletons were found in Brazil."
