23andMe父系祖源科普内容更新

我的父系祖源在23andme上的测试结果为O-JST002611,最近登陆的时候,发现介绍的科普页面有了变化,并且提到
Your haplogroup is common in the Massim groups of Papua New Guinea.

Your haplogroup is prevalent among Massim ethnic groups, including the populations of Airara, Nomanby, the eastern tip of the mainland, the Trobriand Islands, Gawa, Woodlark, the Laughland Islands, and western Calvados. Whiel Papua New Guinea has been inhabited for over 50,000 years, the Massim may have arrived in the last 2,000 years. Today, these populations remain connected through a traditional island trading system called the Kula Ring. Under this exchange system, residents ensure that goods that are only available on some islands, but that are vitally needed in other islands, are shared among the island populations. Only Massim men participate in the Kula exchange system, and it is common for men to be away from home for months at a time when trading with men from other islands.

而之前的页面是用的中国汉族来介绍的,我简单的Google了一下并没有找到相关的内容,所以我以为是个bug,并给客服提交了一个ticket,过了几天客服回复如下
Thanks for contacting the 23andMe Team. In the last several years, scientists have sequenced thousands of Y chromosomes, so we recently updated the paternal haplogroup assignments for 23andMe customers to reflect the ISOGG 2016 reference tree. At this time, the information in your Haplogroups report reflects the most up to date information available.
I appreciate you taking the time to provide feedback about the information included in this report. I have forwarded your comments to our ancestry team to be received.

Please feel free to let us know if you have any additional questions or suggestions.


简而言之是我们没错。

因为我不是学分子生物学的,所以想在这里确认一下这个巴布亚新几内亚的Massim groups真的也有很多人的父系祖源是O-JST002611吗?





多谢了。

注意这句话:While Papua New Guinea has been inhabited for over 50,000 years, the Massim may have arrived in the last 2,000 years.
如果是2kya之内才到的巴新,那可以算作是晚近移民了。
另外,以前很多人对马来-波利尼西亚人父系中存在少量002611成分感到不解,现在也有确定的答案了。

2# baiyueren 多谢回复,我也觉得有少量的002611也没啥好奇怪的,不过它也说“Your haplogroup is prevalent among Massim ethnic groups”,这个prevalent给我一种比例不低的感觉,所以我才觉得这个可能是个bug。
