The Peopling of Indonesia

I am republishing this post because I have significantly reworked the genetics of the Indonesians. Instead of being mostly Austronesians from Taiwan, I now say they are mostly related to an ancient Melanesian Dai group from SE China that came 10-20,000 years ago. This group imposed itself on the original people, who were Papuans.

Later, Austronesians came through, leaving languages but only some genes. The Indonesian type was formerly generalized throughout SE Asia from 2-4,000 years ago and is known as an Ancient SE Asian. This type is primarily Mongoloid but has strong Australoid elements.

The breakdown of Indonesians is approximately 70% Ancient Dai (Melanesian), 15% Austronesians from Taiwan (probably mostly Paiwan and Ami) and 15% Papuan.

The ancient Dai appear to have undergone the same progression towards Mongoloid as occurred with Melanesians throughout Inland SE Asia. In island SE Asia (Melanesia) and the East of Indonesia, this progression was much less complete, so people still have strong Melanesian elements. The degree to which some Melanesians resemble Negritos is rather striking.

To sum up, the new data indicates that most Indonesians are not related primarily to Taiwanese aborigines as originally thought. Instead they are related to Daics from far SE China who left their homeland during post-glacial flooding that occurred after 18,000 years ago. Only 20% of the Indonesian line comes from recent (past 4,000 years) Taiwanese aborigine immigrants.


The prehistory of Indonesia is an interesting question, but it is little studied.


Typical Indonesian men. The one on the left looks very Chinese, or Filipino. The one on the right looks a little different. Indonesians are dark, but the place is right on the equator, so this is to be expected.


Human sites have been found as far back as 33,000 years in the far east Maluku Islands (or Moluccan Islands), but these people are normally referred to as Melanesians. Actually, I think that they were Papuans. Very early man, Homo Erectus, has been found in the islands dating way back.

A multiregional theory has been suggested for the evolution of man in Indonesia, China and maybe other areas. This theory has been rejected, however there may be some continuity in China with older forms dating back 120,000 years or so. The Chinese, the Japanese and now the Indonesians all want to say they came from a different monkey.

The theory is also very popular with White Nationalists who are extremely insulted by the idea of being descended from African Blacks. In Indonesia and China, these ideas have more to do with the spread of idiotically antiscientific nationalist-based theories than anything else.

In Indonesia, the nation's top archaeologist deliberately destroyed bones of Homo Florensis recently in spite over the rejection of his pet theory, that the Homo Erectus relative that lived in modern times are just modern humans who are microencephalic. This theory seems crazy, but is making the rounds in peer-reviewed journals nevertheless.

Nationalism and science has never worked well, with some particularly gruesome results especially in the past century. Florensis is a tiny midget of an early man who is a different species from us. They may have lived up until 600 years ago but the hard evidence so far shows they lived until 13,000 years ago at the latest. I believe they lived until the arrival of the Europeans. It is possible some may yet exist to this day.

There are a lot of questions about whether or not Florensis and locals bred in. Some of the locals are very short and some even think they may have Florensis like features, though the question of inter-species breeding makes little sense. Locals say that the Little People are their ancestors.

The Little People would come to their villages and hide in the forest watching them. Locals would leave food for the Little People in baskets and the Little People would come when no one was around and take the food - they were described as very shy. It is amazing that such a primitive man could live in such proximity to modern Homo without genocidal results.

In the past, contacts between more modern civilizations and more primitive ones usually had genocidal results. Examples include Indonesia, Australia, New Zealand, Japan, Korea, Africa, the Americas, Siberia, and probably other places.

Before Florensis, there is Java Man, who dates back possibly to 2 million years. It is due to the prominence of Java Man that the Indonesian "scientists" have indulged in their childish and petty behavior. Actually, the Indonesian case above is more complicated than that - the destroyer of the skulls is the grand old man of Indonesian archeology and he cannot be touched.

There are a number of younger archaeologists there who think the man is an old fool, which he is, but no can do a thing about him.

The question of Homo Erectus being put aside, we now turn to the development of modern Homo in Indonesia. Here, very little is known for some reason, but we do have that 33,000 yr old find in the Malukus. These people are called Melanesians for lack of a better word, but it also appears that there were cultural contacts with Australians across the straights. I believe that a better term for these early people is Papuans.

At this time, Melanesians were probably generalized all throughout SE Asia.

Sometime around 10-15,000 years ago, these Papuans populate most of the Mulukus. The nature of the aforementioned contacts with the Australians, genetic or otherwise, is not known, but that such early modern man had such excellent boats is stunning. Much is made by racists of the primitiveness and low IQ's of Aborigines.

However, we should note the profound cultural achievement it took to make those boats to get to Australia in the first place. But we had great boats when we first left the African Horn at Somalia and Djibouti, went to Yemen and moved along the coast all the say to SE Asia, stopping along the way in Iran, Yemen, India, Pakistan, Sri Lanka, Burma, Thailand, Indonesia, New Guinea, Melanesia and Australia.

There is a chain of Negritos in every one of these places, probably the last remainders of the first modern men that left Africa 60-70,000 years. In Australia, the Negritos went to Aborigine Major Race; in Papua, they went to the Papuan Major Race, in Melanesia to the Melanesian Minor Race. However, recent data suggests that the Melanesian race is extremely diverse, so it may have to be re-evaluated.

Some analyses show Melanesians clustering fairly close to Papuans, yet others show Papuans as a vast major race, tied with Aborigines as the most diverse on Earth after Africans. They are also some of the furthest away from Africans.

Whites are more closely related to Africans than Papuans are, yet everyone from Afrocentrists to White Nationalists wants to say Papuans are Black people. In the North, they went on to form the early basis for all members of the Asian Macro-race today.

The standard history is that some unknown Melanesians, about which we know little, were the original inhabitants of Indonesia. Recent research sheds some light on the genesis of these Melanesians.

Turner
, a specialist in teeth, using dental morphological traits, hypothesized that two migrations originated from central China about 20-30,000 YBP (years before present).

One group, the Sinodonts, expanded northward into China, Siberia and across the Bering land bridge to the New World. The second group, the Sundadonts, moved southward into Southeast Asia and Indonesia, and later through Melanesia, Micronesia, and Polynesia.

This is probably the group that gave rise to the Melanesians.

But the picture is more complicated than that.

Indonesians were settled independently by ancient Dai. These Dai came from from Hainan and Guangxi in far southern China about 10-20,000 YBP. They may have left due to rising sea levels that flooded their lands. The ancient Dai must have looked like Melanesians.

The people most closely resembling the ancient Dai are the Taiwan aborigines. It is true that the Indonesians do not much resemble the Taiwan aborigines genetically, and their genetic structure in general is quite a bit different from Filipinos.

However, this study does not explain how Indonesians came to speak Austronesian languages obviously derived ultimately from Taiwan.

It is clear to me that when the Austronesians pushed through Indonesia several thousand years ago, the locals adopted the Austronesian tongues of the Austronesian colonizers, abandoning whatever tongues they were speaking at the time (I figure Papuan languages).

Recent tests indicate that the Indonesians derive 71% from the ancient Dai, 14% from the Taiwan aborigines (Austronesians) and 15% from Papuans. This study looks at Y chromosomes. 10-20,000 years ago, these ancient Dai went from Hainan and Guangxi (their homeland) to Taiwan to become the Taiwan aborigines and also on to Indonesia in two separate waves.

They probably genetically swamped and colonized the native peoples, who were probably Papuans.

Today, only the Malukus identify as Melanesians, despite the fact that there are Melanesians on Alor and in other places. On Timor, Sumba and Flores, there are people who are at least part-Melanesian who do not really identify as Melanesian. Some of these people are up to 80% Melanesian, as in Alor.

The standard history of the rest of the islands, such as Sulawesi, Sumatra, Bali is that Austronesians came 4,000 years ago and pushed the native Melanesians to the east. However, this standard history must be wrong. Instead of pushing Melanesians east, they bred in with them.

Most Indonesian is an example of a race that used be common all through SE Asia, including Vietnam - the Ancient SE Asian Race. This race was widespread throughout SE Asia 2-4,000 years ago. It is a Mongoloid with considerable Australoid admixture.


Tsunami victims in Aceh on Sumatra. They are quite dark as you can see, but that is probably a pigmentation process to enable females to store folic acid for pregnancy in order to give birth to viable infants. Protection against sunburn is an interesting theory, but sunburn, even melanoma, does not kill you.

They are members of the Island SE Asian Race, along with the Balinese pictured below. Like the Balinese, they may have an origin in part with the Paiwan aborigines of Taiwan.


The Sumba and probably all of the other Lesser Sunda Islands are inhabited by people who are a mixture between Austronesians from Taiwan and native Melanesians - Ancient SE Asians, as described above. Timor also has Papuans and Polynesians. Early man arrived on Timor as early as 40,000 years ago. These people must have been Papuans.

The Mulukus such as Babar and Ambon are inhabited by mixtures of Austronesians from Taiwan, Papuans in the case of Ambon and Melanesians in the case of Babar.

4,000 YBP, the Austronesians arrived in Indonesia from Taiwan. Mostly, these were the Ami, but there is a possibility that other Taiwanese aborigines were also, in particular, the Paiwan.

These were the Austronesians, the greatest mariners of all time, who settled Philippines, Indonesia, coastal New Guinea, Melanesia, Micronesia and Polynesia. There are even said to have moved into mainland SE Asia, particularly Malaysia. In that case, they probably went to Sumatra first and then moved across the water to Malaysia.


These Indonesian Muslim women praying look very much like Malays. It is not known where they are from. They may be members of the Malay Race found on Java and Borneo in Indonesia described at the end of the post.


They even seem to be a major component of the Vietnamese. Everywhere they went, the Austronesians brought a cultural revolution with them, often upgrading existing cultures, certainly so in the case of New Guinea.

Austronesians arrived in Indonesia at least 4,000 years ago by boat, probably from the Philippines, where they already probably had a mature settlement. However, the Austronesian show up in Timor as early as 5,000 years ago, so 4,000 years BP may be too late.

Next, at least on Timor, and probably throughout Indonesia, a wave of proto-Malays moved through. A group settled Bali 5,000 years ago who may have been proto-Malays. Proto-Malays are also important in the settlement of the Philippines and Malaysia.

The proto-Malays who settled in the Philippines were said to be short and very hairy. The hairiness is odd for people living in a hot climate. If this description is true, I suggest that the proto-Malay may have been an Ainu-like people, the proto-NE Asians. A Southern origin is possible for the Ainu. The pre-Ainu, the Jomon, are said to have origins in Thailand 18,000 years ago. They got on boats and sailed to Japan.

These hairy proto-Malays may have been related to the pre-Jomon in Thailand long ago. Proto-Malays show up in the Philippines over 5000 years BP, before the arrival of the Austronesians. The proto-Malays who settled the Philippines and Indonesia are said to have had an origin in South China and inland SE Asia.

However, in Malaysia, the proto-Malay are said to have been created in Malaysia 3000 years ago as Austronesians bred in with existing Senoi, an Australoid or Negrito like people. The Proto-Malays are poorly understood, and some of what is said about them is contradictory.

Austronesians show up in Sulawesi, Java, the Mulukus and Borneo 3,500 years ago. Austronesians moved from Borneo to Sumatra 2,500 years ago, and from there up into Malaysia to become a component of the Malay Race.


A beautiful woman on Samosir Island on Sumatra. She may be a Toba Batak, who are members of the Micronesian Race. Unless I am hallucinating, I think that many Micronesians look something like this. A possible explanation is that the Batak are the remains of those Austronesian-Melanesian mixes who populated Polynesia and then left Polynesia to populate Micronesia, but the situation is quite confused.

In the background is one of the famous Toba Batak bark houses. She is in traditional dress. Note the resemblance to a Filipina.

The Batak, like the Sea Dayak of northern Borneo and the Nesiot and Igorot of the Philippines, are linked to the first Austronesian wave out of Taiwan 5,000 years ago. This group is also linked to the Paiwan tribe on Taiwan.


A cultural revolution in Indonesia called Đông Sơn was paralleled by similar developments throughout SE Asia. This culture was centered in the Red River Valley of northern Vietnam and northward in southern Kwangzi and Kwangtung of China, while being generalized throughout Indonesia, showing up about 3,000 years ago. Originally, the Đông Sơn were said to be Austronesians, but the latest thinking is that this is an ancient Tai group.

Wet-rice cultivation spread throughout the islands with Đông Sơn, but the native Melanesians were already engaging in wet-rice cultivation an incredible 10,000 years ago, making Indonesia one of the earliest sites for agriculture on Earth.

The Đông Sơn culture was developing in Vietnam from 2,200-2,800 YBP.

The Đông Sơn kept buffaloes and pigs, fished, grew rice and, in a clue to their Austronesian nature, sailed in long dugout canoes. An Iron Age people, they utilized metallurgy to make fine bronze objects, including drums and figurines.

Racially, the Đông Sơn peoples belonged to Indonesian or Ancient Southeast Asian group - a Southern Mongoloid with strong Australoid elements (Cuong, 1996).

Đông Sơn also had elements of Dai culture from Yunnan and Laos, Khmer culture of Cambodia, Tibeto-Burman culture, and the prehistoric Plain of Jars culture in Laos. So all of these elements from mainland SE Asia and Southern China went into the stew that became Indonesian culture.

Now, Indonesians are members of either the SE Asian Major Race, the Oceanian Major Race or the Papuan Major Race. For the most part, they seem to be some sort of a mixture between ancient Daic Melanesians and Austronesian Chinese (Taiwanese).

Haplogroups C, E and F in Figure 1 here, seem to have a southern origin. These strains are apparent on a minor scale in Java, Borneo and Sulawesi. But in Southern Borneo, they reach levels up to 40%. Haplogroups G, H and L are also associated with Taiwan, the Philippines and to a lesser extent South China.

L is clearly the Ami of Taiwan but G and H are less well-understood. This paper suggests that they have a southern (Melanesian) genesis, but that does not make much sense. H is present at high levels in the Taiwanese Atayal, Bunum and Paiwan, and G is present at high levels in the Bunum and the Paiwan. G is at even higher levels in Javans.


Some beautiful, typical, Indonesian women with the usual phenotype. Note the resemblance with Thais, Filipinas, and possibly Khmers. I believe that these women may be Balinese, but correct me if I am wrong. If so, they are members of the Island SE Asian Race that may have its origins in the Paiwan aborigines of Taiwan.


On a principle coordinates map here (Figure 4), Indonesians cluster close to Filipinos, the Ami of Taiwan and Southern Chinese.

That paper, referenced in the several paragraphs above, may be downloaded on this site here.

Indonesians today constitute several races. Papuans and Melanesians were mentioned above. The Toba Batak are Micronesians, but how they ended up in northern Sumatra is a mystery.

Indonesians on Java and northern Borneo are members of the Malay Race, also found in Malaysia. Indonesians from Sumatra, Bali and the Sea Dayak of northern Borneo, along with the Paiwan aborigines from Taiwan, are members of the Island SE Asian Race.

The Sea Dayak are also linked anthropologically with the first wave of Austronesians out of Taiwan 5,000 years ago, along with the Nesiot and Igorot in the Philippines. The suggestion is that the first wave of Austronesians may have been related to the Paiwan tribe.

This clustering is odd, and suggests that the Paiwan, in addition to the Ami, may have been among the Austronesian seafarers who populated Indonesia.


Click to view details. Map showing the Paiwan, Atayal, Bunum and Ami aborigines of Taiwan. The Paiwan seem to have a relationship with the Sea Dayak of North Borneo, the Balinese, and the Sumatrans. This indicates that the Paiwan, located on the lower right on the map, may have helped to settle Indonesia as Austronesians along with the Ami who are usually associated with Austronesians. Note that both the Paiwan and the Ami were properly positioned to colonize island SE Asia.


The Indonesians of Sulawesi, the Lesser Sundas and Borneo are members of the mainstream Indonesian Race.
