Previously documented genetic contributions were confirmed from two ancient groups. The first was Japan’s indigenous culture of hunter-gatherers dating to roughly 15,000 years ago, the start of what is called the Jomon Period. The second was a population of Northeast Asian origins who arrived at about 900 BC, bringing wet-rice farming during the subsequent Yayoi Period.

Modern Japanese possess approximately 13% and 16% genetic ancestry from those two groups, respectively, the researchers determined.

But 71% of their ancestry was found to come from a third ancient population with East Asian origins that arrived at roughly 300 AD.

These migrants appear to have had ancestry mainly resembling the Han people who make up most of China’s population.

At precisely this period Japan also suddenly got writing and its architecture/cultural traits, which all happen to closely resemble Chinese culture. i.e the islands were colonized by Chinese settlers. The aboriginal natives were exterminated/bred out.

Japan is rightful Chinese clay.

And even with all those genetic similarities, you will have a hard time finding two groups of people who hate each other more than these two. If one wants to point fingers, if would be easy to point to the Japanese as the villans of this story but life is always more complicated than that.

Genetics means nothing compared to social and cultural elements, Igor. I imagine that most people in the former Republics of Yugoslavia have very similar genetic background, what difference did that make?

Remove foreign influences and we're best friends. We call all croats/serbs/bosniaks 'nasi' or 'our people' when abroad. It's all foreign imported animosity propped up by foreign empires. Division and conquest. Bosnia and Croatia are now controlled by Brussels. Serbia remains independent.

There was a major influx of Han Chinese migrants from mainland China during the Kofun period from the 3rd to the 7th centuries. One Kofun sample from the period (KOFUN) carried Y-DNA haplogroup O3a2, which is a major Han lineage, covering 35% of the Han Chinese population today. However, the frequency of this Chinese haplogroup is 19%-24% in the modern Japanese population, while the Jomon D1b lineage makes up 25%-55% in Japanese males. The study probably overestimated the demographic impact of the Han migration due to its limitations, thus underestimating the Jomon genetic heritage.

Our initial screening focused on 14 ancient skeletal remains excavated from six archaeological sites across the archipelago (see note S1). High levels of endogenous human DNA were preserved in 12 of these samples (Table 1), which were then further shotgun-sequenced to higher coverage, ranging from 0.88× to 7.51× (Fig. 1 and table S1). Nine of the 12 samples are associated with the Jomon culture, representing the west and central parts of the archipelago and four different stages of the Jomon period (Initial, Early, Middle, and Late Jomon) (Fig. 1). The remaining three samples date to ~1.3 ka ago, falling within the Kofun period. We confirm that all newly sequenced genomes show postmortem damage patterns (fig. S1) and a low level of modern human contamination (<2.15%) (Table 1 and table S2). Our kinship analysis confirms that all pairs of individuals are unrelated (fig. S2). Mitochondrial haplogroups for all Jomon individuals belong to the N9b or M7a clades, which are strongly associated with this population (11–14, 22) and rare outside of Japan today (23). The three Jomon males (table S3) belong to the Y chromosome haplogroup D1b1, which is present in modern Japanese populations but almost absent in other East Asians (24). In contrast, the Kofun individuals all belong to mitochondrial haplogroups that are common in present-day East Asians (25), while the single Kofun male has the O3a2c Y chromosome haplogroup, which is also found throughout East Asia, particularly in mainland China (26).

Is that a resemblance in the same way Wikipedia https://en.wikipedia.org/wiki/Genetic_h ... ast_Asians says East Asians and sometimes claims SEA are closely related to Han?
