Story

The narrative of this ancient life

The Jomon Period is one of the most fascinating epochs in the prehistoric era of Japan and is characterized by a unique combination of cultural, technological, and environmental developments. Spanning from approximately 14,000 BCE to 300 BCE, the Jomon Period is named after the intricate cord-marked or \jomon" patterns found on the pottery of the time, marking one of the earliest instances of pottery production in the world.

Chronological Overview

  1. Incipient Jomon (ca. 14,000–8000 BCE):

    • Environmental Context: The end of the last Ice Age brought significant climatic changes to the Japanese archipelago, leading to more temperate and stable environmental conditions suitable for plant and animal life.
    • Lifestyle: Communities lived primarily as hunter-gatherers with a reliance on fishing, exploiting the rich marine resources along the coasts, rivers, and lakes.
  2. Initial Jomon (ca. 8000–5000 BCE):

    • Technological Advancements: The development of pottery for storage and cooking becomes more common. Early Jomon pottery features simple designs but indicates a deep understanding of material properties and firing techniques.
  3. Early Jomon (ca. 5000–2500 BCE):

    • Social Developments: As settlements grew in size, there is evidence of increased social organization. Settlements typically formed near water sources and abundant food supplies.
    • Pottery: Pottery becomes more decorative and intricate, with characteristic cord-marking patterns. The shapes varied from deep bowls to shallow vessels, indicating diversified usage.
  4. Middle Jomon (ca. 2500–1500 BCE):

    • Population Growth: There is a peak in population density, suggesting a more sedentary lifestyle with semi-permanent villages.
    • Cultural Artifacts: The period witnesses an explosion in artistic expression, including elaborately decorated pottery and clay figurines known as "dogu," believed to have ritual or religious significance.
  5. Late Jomon (ca. 1500–1000 BCE):

    • Environmental Challenges: A slight cooling of the climate may have led to changes in vegetation and the availability of certain animal species, causing shifts in settlement patterns and resource procurement strategies.
    • Innovations and Trade: Increased interaction with neighboring regions, particularly with cultures on the Korean Peninsula, leads to cultural exchanges and technological innovations such as improved fishing tools and techniques.
  6. Final Jomon (ca. 1000–300 BCE):

    • Transition Phase: The transition towards more agriculture-based communities begins, setting the stage for the subsequent Yayoi period.
    • Cultural Continuity: Despite external influences, Jomon culture maintains continuity and influences the developing cultural landscape of the Yayoi period.

Cultural Aspects

  • Subsistence and Diet: The Jomon people had a diversified diet that included marine and terrestrial resources. They gathered nuts, seeds, and fruits; hunted deer and boar; and caught fish and shellfish, which are evidenced by shell middens.

  • Habitation: Jomon settlements typically consisted of pit dwellings with thatched roofs, organized in circular or horseshoe configurations. These settings were often strategically chosen for resource availability and protection from the elements.

  • Art and Spirituality: The Jomon were not merely survivalists; they exhibited a complex spiritual life, possibly evidenced by ritualistic patterns in their ceramics and enigmatic dogu figurines, which are interpreted to have shamanistic or fertility purposes.

  • Pottery and Craftsmanship: Jomon pottery is notable for its artistry and variety. It serves as a durable record of their cultural practices and aesthetic preferences. The cord markings on the pottery vary from region to region, indicating diverse cultural expressions within the broad Jomon culture.

Legacy

The Jomon Period significantly influenced Japan's cultural and historical trajectory. The technological and artistic achievements of the Jomon people laid the groundwork for future advancements in Japanese societies. The period's end did not mean a sudden disappearance of its influences but rather a gradual evolution into more agriculturally focused societies in the Yayoi Period, integrating previous hunter-gatherer practices.

In modern Japan, the Jomon legacy is celebrated and studied for its contribution to understanding prehistoric human life, adaptability, and resilience in varying environmental conditions. The rich archaeological record continues to provide insight into the social, technological, and artistic intricacies of the Jomon people."

Genomic insights into the formation of human populations in East Asia

Authors Wang CC, Yeh HY, Popov AN
Abstract

The deep population history of East Asia remains poorly understood owing to a lack of ancient DNA data and sparse sampling of present-day people1,2. Here we report genome-wide data from 166 East Asian individuals dating to between 6000 BC and AD 1000 and 46 present-day groups. Hunter-gatherers from Japan, the Amur River Basin, and people of Neolithic and Iron Age Taiwan and the Tibetan Plateau are linked by a deeply splitting lineage that probably reflects a coastal migration during the Late Pleistocene epoch. We also follow expansions during the subsequent Holocene epoch from four regions. First, hunter-gatherers from Mongolia and the Amur River Basin have ancestry shared by individuals who speak Mongolic and Tungusic languages, but do not carry ancestry characteristic of farmers from the West Liao River region (around 3000 BC), which contradicts theories that the expansion of these farmers spread the Mongolic and Tungusic proto-languages. Second, farmers from the Yellow River Basin (around 3000 BC) probably spread Sino-Tibetan languages, as their ancestry dispersed both to Tibet-where it forms approximately 84% of the gene pool in some groups-and to the Central Plain, where it has contributed around 59-84% to modern Han Chinese groups. Third, people from Taiwan from around 1300 BC to AD 800 derived approximately 75% of their ancestry from a lineage that is widespread in modern individuals who speak Austronesian, Tai-Kadai and Austroasiatic languages, and that we hypothesize derives from farmers of the Yangtze River Valley. Ancient people from Taiwan also derived about 25% of their ancestry from a northern lineage that is related to, but different from, farmers of the Yellow River Basin, which suggests an additional north-to-south expansion. Fourth, ancestry from Yamnaya Steppe pastoralists arrived in western Mongolia after around 3000 BC but was displaced by previously established lineages even while it persisted in western China, as would be expected if this ancestry was associated with the spread of proto-Tocharian Indo-European languages. Two later gene flows affected western Mongolia: migrants after around 2000 BC with Yamnaya and European farmer ancestry, and episodic influences of later groups with ancestry from Turan.
