I haven't read the whole article yet, but it seems that there are few "big" surprises. It basically confirms what we already knew about the relationships between mainland Asians (including South, Northeast and Southeast ones), Oceanians, Americans and West Eurasians. Split times between populations are too recent IMHO (only 34K between West and East Eurasian, incl. Oceanians) and Africans (Yoruba)/non-Africans (~60K on average).

They have found low levels of Denisovan DNA in most of the studied Asian populations (interestingly, some IE-speakers from India have substantially lower levels than other Indians) that are higher in some SE Asian and Oceanian populations (this has already been described in a couple of recent studies).

It's a pity we have so few Australian genomes... I'd love to read a genome project on Oceanians. It seems that the genomic history of that region is very complex.

There are many studies that show the Sunda land had many R* people settlement that got submerged from 25K ybp to 5k ybp.

Philippines...my paternal line P1 and maternal M7 are from the Cebu and Negros Island areas. Amazing to think that they were alive when Sunda still existed.

Hi All,

I am Malay from Singapore.

My paternal line is M1 while maternal line is R22.

Haplogroup M to M4
Possible time of origin: 8,200 [3,800–20,600] years BP (Kayser 2003)
Possible place of origin: Southeast Asia - Melanesia
Ancestor: M-P256

Haplogroup R22 is a branch on the maternal tree of human kind. Its age is between 23,900 and 38,900 years (Behar et al., 2012b).
National Geographic Geno 2.0 Text
Haplogroup: R22
Age: To Be Determined
Origin: Southeast Asia
Blurb: This point in your ancestors’ journey took place in Southeast Asia. Today, this lineage is most common in Indonesia. It is also present at low frequencies in Thailand.
