DNA Analysis of Micronesians


Micronesia is defined as a country and has been a much-ballyhooed friend in need for Israel at the United Nations. It actually consists of roughly 2,000 small islands spread over a vast region in the Pacific. 

Micronesia should not to be confused with the neighboring nations of Polynesia or Melanesia, which also consist of small islands in the Pacific. Now, a new study casts light on the origin of early Micronesians and it is more complicated than had been assumed.

It had been thought that Micronesians shared origins with southwest Pacific peoples, and that Micronesians likely stemmed from a single origin. 

Now, analysis of ancient and modern Micronesian DNA has detected five separate waves of migration to Micronesia in antiquity: three streams from eastern Asia, one from Polynesia, and one of people related to mainland Papua New Guineans, Yue-Chen Liu and David Reich of Harvard Medical School reported with colleagues last week in Science.

The three streams of “first remote Oceanian” migration into Micronesia included a previously unknown lineage, the team adds.

The study is based on genomic analysis of 164 people who lived 2,800 to 500 years ago at five sites around Micronesia, and 112 genomes of present-day people from the same areas.  READ MORE...
