AncientDNA(aDNA) reveals five streams of migration into Micronesia and matrilocality (patterns of marriage in which the groom resides with the bride’s parents) in early Pacific seafarers. Those new insights, revealed in a June 30 article in Science, were gleaned from research involving four co-authors with University ofHawaiʻiat Mānoa ties:

Prior to this study, the inhabiting of this vast region had been a mystery. “I am so proud that we have contributed to a better understanding of the bioarchaeology and archaeology of Micronesia, including the Mariana Islands and Pohnpei, the Pacific and beyond,” said Pietrusewsky.
The work reveals five previously undocumented migrations into Micronesia, and suggests that approximately 3,500 to 3,200 years ago early inhabitants of Remote Oceania, including Guam and the Northern Mariana Islands, had matrilocal population structures where migrants joining new communities were almost always men. The practice is different from patrilocal societies where women are the ones to leave their own community. Patrilocal residence is the most typical pattern found in modern human cultures worldwide.
The five migrations detected included:
Three from East Asia.
One from Polynesia.
One from the northern fringes of mainland New Guinea.
The results come from a genome-wide analysis on 164 ancient individuals from 2,800 to 300 years ago, as well as 112 modern individuals.
“An interesting finding was that, unlike the pre-contact and modern people of Central Micronesia, the present-day Indigenous people of the Mariana Islands derive nearly all their pre-European-contact ancestry from two of the East-Asian-associated migrations—making this one of the few places in Remote Oceania without Papuan ancestry,” said Pietrusewsky.
Future research will hopefully involve modern and a DNA from other Pacific island communities that have an interest in learning more about biological origins, family structure and social customs of their ancestors.
DNA Analysis of Ancient Micronesians Has Unexpected Result
Far out in the remote Pacific Ocean, the 2,000 islands of Micronesia were only peopled about 3,500 years ago, archaeological evidence shows. Now we find it didn't happen quite as had been assumed

NASHVILLE, Tenn. (WKRN) – Tennesseans have been fascinated by caves for centuries. And long before that, when Native Americans inhabited the rolling landscape, they too traversed the deep dark rock masses leaving meaningful messages uncovered thousands of years later.
“There are these hidden treasures and gems everywhere,” said Jan Simek who has a long list of accolades to his name, including Distinguished Professor of Anthropology at the University of Tennessee.
He’s also the man who led the team that uncovered hundreds of images of prehistoric cave art. “Tennessee, Alabama, Kentucky in particular, but Georgia as well, is one of the richest areas for caves anywhere in North America,” Simek said.ADVERTISING
Nestled in these undisclosed locations are images both carved and painted on rock walls miles inground. “We’ve been in thousands, in order to find the few hundred,” explained Simek.
One, in particular, discovered within the Cumberland Plateau which cuts across Tennessee between Chattanooga and Nashville was drawn 6,000 years ago – the oldest to date in North America.
“6,000 years ago, people were hunting and gathering. They were fishing. They were highly mobile,” said Sarah Sherwood, a Professor of Archaeology at the University of the South at Sewanee, who’s part of Simek’s team.

She explained the reaction to cave art is still the same. “There are lots of oohs that go on among all of us when you first see it. It’s just so exciting.”
Also along the treacherous trails are artifacts of those who traveled before. “We see the cane river torches that people used scattered all over the place, gourds that they used to pick things up with, basketry,” Simek said.
Images of animals, figures, and symbols meant to record tribal events and spiritual transformations.
“Red is the color of life of birth, black is the color of death. And so it sets off the relationship between what we find in caves, which is related to the underworld, and what we find on the bluff tops, which is related to the celestial realm, the upper world,” explained Simek.
All of which were important to indigenous people and their circle of life.
“This experience has sort of heightened your curiosity and your creativity, about the way people were living in the past,” Sherwood said. “It gives them much more of a three-dimensional life, like our own in terms of spirituality and connections to a place, and to family, and to our kin, our ancestors.”
People can experience this wonder up close in Clarksville.
“That is Dunbar Cave, north of Nashville,” Simek said. “Where a very large archaeological site had accumulated in the mouth of that cave. We know it that goes back 10,000 years.”
The site is also home to significant Prehistoric Native American cave art. Another stop on their journey to new discovery as they continue to preserve the past.
“I think we’ll all keep doing it,” Sherwood says with an infectious laugh, “as long as our knees will hold up.”
