(erupted in 1883). The region is known for its instability due to volcano formations and other volcanic and tectonic activities as well as climate changes; resulted in lowlands drowned occasionally under shallow seas, the formation of islands, the connection and disconnection of islands through narrow land-bridges, etc.
The Indonesian archipelago nearly reached its present form in the
Aru Islands
were separated from the Australia mainland. The rise of sea surface created isolated areas that separated plants, animals and hominid species, causing further evolution and specification.
Human migration
Homo erectus
In 2007 analysis of cut marks on two bovid bones found in
Ngandong alongside more advanced tools, re-dated in 2011 to between 550,000 and 143,000 years old.[3][4] In 1977 another Homo erectus skull was discovered at Sambungmacan.[5]
Homo floresiensis
In 2003, on the island of
island dwarfism. Homo floresiensis was first dated to relatively recent time periods - as recent as 14,000 years ago,[7] however re-examination of the sediments has revised these dates and these hominins have been shown to have been present in Indonesia since at least 700,000 years ago, until about 60–50,000 years ago.[8] In 2010 stone tools were discovered on Flores dating from 1 million years ago, which is the oldest evidence anywhere in the world that early man had the technology to make sea crossings at this very early time.[9][failed verification

Homo sapiens
The archipelago was formed during the thaw after the latest
Homo sapiens reached the region by around 45,000 years ago.[10] In 2011 evidence was uncovered in neighbouring East Timor, showing that 42,000 years ago these early settlers had high-level maritime skills, and by implication the technology needed to make ocean crossings to reach Australia and other islands, as they were catching and consuming large numbers of big deep-sea fish such as tuna.[11]
Earliest migration
Early Homo sapiens reached the archipelago between 60,000 and 45,000 years ago. Many but not all
Aeta). The descendants of the pre-Austronesian inhabitants of the Indonesian Archipelago are still the majority in the eastern portion of the region, in islands such as New Guinea, the Maluku and East Nusa Tenggara. Genetic studies show that in Western Papua there was significant genetic admixture between Negritos, Australo-Melanesians and Austronesians.[14]
Rock art
Approximately 40,000 years ago, early humans produced prehistoric rock art motifs in volcanic caves on the island of Sulawesi. This means that humans at both extremes of the Pleistocene Eurasian world, Europe and Indonesia, were producing rock art during the same time period.[15] The most notable rock art sites in Indonesia are the Maros-Pangkep rock art sites at the caves in South Sulawesi province. There are two distinct styles of art within these caves, both dated to the Pleistocene period. The first consists of human hand stencils, made by spraying wet pigment spit from the mouth, around human hands that were pressed against the cave wall surfaces. The second is a less common style of cave art, characterized by images drawn of larger, naturalistic profile paintings of wild land mammals that were endemic to the island during the Pleistocene period, such as miniature buffalos and warty pigs.[16]
Other than Altamira, the Maros cave art is one of the most extensive sites of cave rock art in the world. These Indonesian prehistoric cave paintings might be the oldest cave art in the world. This find has challenged the established interpretation that Europe was the birthplace of prehistoric rock art.[17]
On 11 December 2019, a team of researchers led by Dr. Maxime Aubert announced the discovery of the oldest hunting scenes in prehistoric art in the world which is more than 44,000 years old from the limestone cave of Leang Bulu’ Sipong 4. Archaeologists determined the age of the depiction of hunting a pig and buffalo thanks to the calcite ‘popcorn’, different isotope levels of radioactive uranium and thorium.[18][19][20][21]
On 16 March 2020, a team of archaeologists led by Griffith University has uncovered the first known examples of ‘portable art’, which are probably 14,000 - 26,000 years old, from a limestone cave named Leang Bulu Bettue in Sulawesi and published in the academic journal Nature Human Behaviour. While one of the stones contained an anoa (water buffalo) and what may be a flower, star or eye, another depicted an astronomic rays of light.[22][23][24]
In January 2021, archaeologists announced the discovery of at least 45,500 years old cave art in Leang Tedongnge cave. According to the journal Science Advances, cave painting of warty pig is the earliest evidence of human settlement of the region. Adult male pig, measuring 136 cm x 54 cm, was depicted with horn-like facial warts and two hand prints above its hindquarters. According to co-author Adam Brumm, there are two other pigs that are partly preserved and it appears, the wart pig was observing a fight between two of them.[25][26][27][28]
Prehistoric jewelry
Ornaments made from bones and teeth of
Ailurops ursinus) marsupial, was unearthed from limestone caves in Sulawesi. These jewellery was ingeniously manufactured from the teeth of the primitive pigs and bones of marsupials, estimated dated to between 22,000 and 30,000 years ago.[29]
Austroasiatic migration and admixture
Indochina swayed the demographics of the archipelago.[12] Scientists suggest that there were two major migratory flows into the archipelago that were ancestral to modern Indonesians. First, Austroasiatic speakers arrived around 6,300-5,000 years ago, and then, Austronesian speakers arrived around 4,000 years ago.[13][12][30]
The Austroasiatic and Austronesian languages may have originally come from a larger common language family, the Austric languages. The language may have been spoken by Yunnan people of Southern China before breaking into the two previously mentioned language families.[13] However, this is a controversial hypothesis that not all linguists agree with.
Austroasiatic people spread via Indochina, from Yunnan in Southern China to Vietnam and Cambodia, then to the Malay Peninsula before finally arriving in Sumatra, Borneo and Java. Genetic studies show that Javanese, Sundanese and Balinese people have significant proportion of Austroasiatic ancestry.[31]
Genome studies show that several ethnic groups in western Indonesian archipelago have significant
Austroasiatic genome markers, despite none of these groups speaking Austroasiatic languages. Thus this could mean, that there was either once a substantial Austroasiatic presence in Island Southeast Asia, or Austronesian speakers migrated to and through the mainland. The substantial presence of Austroasiatic ancestry in western Indonesian archipelago suggests that the western branch of Austroasiatic migration from Indochina might have taken place in pre-Neolithic era. The contesting suggestion argues for Austroasiatic-Austronesian admixture — which probably took place in the Malay Peninsula or southern Vietnam, intermixing there before continuing to western Indonesia.[14]
Austronesian migration and expansion
Austronesian speakers came to Indonesian archipelago circa 4,000 years ago.[13] Both Austroasiatic and Austronesian branched from Southern China. However, unlike Austroasiatic people that spread south through the continent, the Austronesian group developed in Taiwan and spread by island hopping throughout the region.
Austronesian people sailed through the region and performed island-hopping — from Taiwan south through the Philippines Archipelago - and reached the central Indonesian archipelago. From there they expanded to western Indonesia and eastern Indonesia, where they met earlier inhabitant Australoid people. In addition, the western branch arrived in Borneo, Java and Sumatra where it met the Austroasiatic migrants, in addition to the existing Australoid population.[13]
Austronesian soon become the dominant group replacing the Australoid population, that today remains significantly only in the Eastern region. On the other hand, Austronesian successfully influenced the Austroasiatic speakers, so finally all of the population in the Western Indonesian archipelago became Austronesian speakers,[13] despite some ethnic groups (Javanese, Sundanese, and Balinese) showing significant Austroasiatic genetic markers. Genome studies discovered that the inhabitants of central and eastern Indonesian archipelago have a significant Austronesian ancestry.[14]
Around 2,000 BCE there was an expansion of seafaring Austronesians from Asia, who spread throughout Maritime Southeast Asia all the way to Oceania and in later period reached Madagascar. Austronesian people form the majority of the modern population of Indonesia.[32]
Chronology
Paleolithic
Homo erectus were known to utilise simple coarse
Ngandong. Cut mark analysis of Pleistocene mammalian fossils documents 18 cut marks inflicted by tools of thick clamshell flakes on two bovid bones created during butchery at the Pucangan Formation in Sangiran between 1.6 and 1.5 million years ago. These cut marks document the use of the first tools in Sangiran and the oldest evidence of shell tool use in the world.[33]
Neolithic
The polished stone tools of Neolithic culture, such as polished stone axes and stone hoes, were developed by the Austronesian people in the Indonesian archipelago. Also during the Neolithic period, large stone structures of the megalithic culture flourished in archipelago.
Megalithic
The
Austronesian megalith cultures both past and present. Several megalith sites and structures are also found across Indonesia. Menhirs, dolmens, stone tables, ancestral stone statues, and step pyramid structure called Punden Berundak were discovered in various sites in Java, Sumatra, Sulawesi, and the Lesser Sunda Islands
. These megalith cultures remained preserved, isolated and undisturbed well into the late 19th century.
Bronze Age
Nusa Tenggara. The artefacts from this period are Nekara bronze drums
discovered throughout Indonesian archipelago, and also ceremonial bronze axe.

Belief system
Early Indonesians were
ancestral spirits of the dead, as they believed their souls or life force could still help the living. The reverence for ancestral spirits is still widespread among Indonesian native ethnicities; such as among Nias people, Batak, Dayak, Toraja, and Papuans. These reverence among others are evident through the harvest festivals that often invoked the nature spirits and agriculture deities, to the elaborate burial rituals and processions of the deceased elders to preparing and sending them to the realm of ancestors. The prehistoric spirit of ancestors or nature that possess supernatural abilities is identified as hyang
in Java and Bali, and still revered in Balinese Hinduism.
Way of life
The human livelihood of prehistoric Indonesia ranges from simple forest hunter-gatherer equipped with stone tools to elaborated agriculture society with grain cultivation, domesticated animals, with weaving and pottery industry.
Ideal agricultural conditions, and the mastering of wet-field rice cultivation as early as the 8th century BCE,[36] allowed villages, towns, and small kingdoms to flourish by the 1st century CE. These kingdoms (little more than collections of villages subservient to petty chieftains) evolved with their own ethnic and tribal religions. Java's hot and even temperature, abundant rain and volcanic soil, was perfect for wet rice cultivation. Such agriculture required a well-organised society in contrast to dry-field rice, which is a much simpler form of cultivation that doesn't require an elaborate social structure to support it.
Buni culture clay pottery was flourished in coastal northern West Java and Banten around 400 BCE to 100 CE.[37] Buni culture was probably the predecessor of Tarumanagara kingdom, one of the earliest Hindu kingdom in Indonesia that produces numerous inscriptions, marked the beginning of historical period in Java.
