West Africa’s Oldest Occupied Site Unearths 150,000 Years of History
西非最古老、被的址揭露了，15年的史。
1. 一自西非塞加，巴尼1近海岸之址，中石器代石器合的石核。 (援用自原文)
A core from the Middle Stone Age stone tool assemblage from the near-coastal site of Bargny 1.
A recent study reveals the oldest directly dated archaeological site in West Africa, extending the known timeframe of Middle Stone Age toolkits in the region to 150,000 years ago.
一最近的研究揭露了，於西非最古老、直接被定年代的考古址。址中，已知之中石器代工具包的(框)，延至15年前。
The findings highlight the long-term durability of core elements of Middle Stone Age toolkits in West Africa and suggest that the enduring cultural continuity may be due to stable behavioral adaptation to stable environmental conditions and potential isolation from other populations across Africa.
此些研究果了，西非中石器代工具包之石核成部分的期耐用性，且暗示持久的文化性可能是由於，定的境件及非洲各地，其他族群在性隔之定行方面的。
Evidence from West Africa about human evolution remains scarce, but recent research has indicated unique patterns of cultural change in comparison to other regions of the continent.
自西非，有人演化的仍然稀少。不，在非洲大其他地的比中，最近的研究已示了，文化化的多特模式。
A new article in the journal Nature Ecology and Evolution adds to our understanding with a study of the oldest directly dated archaeological site in West Africa. The site shows technological continuity spanning roughly 140,000 years and offers insights into the ecological stability of the region.
於《自然•生演化》的一篇新文，以一在西非最古老、直接被定年代的考古址研究，增添了我的理解。址展了，跨大14年之技上的性，提供了地生定性的洞察力。
Our species emerged in Africa around 300 thousand years ago and until around 30-60 thousand years ago typically used tools and tool-making techniques referred to as Middle Stone Age toolkits.
咱物大30年前，出於非洲。直到大3至6年前，有代表性地使用，被中石器代工具包的工具及工具造技。
Around that time, distinct Later Stone Age toolkits began to emerge in northern, eastern, and southern Africa. While recent evidence suggests Middle Stone Age toolkits persisted in West Africa much later, to around 10 thousand years ago, the antiquity of these technologies is poorly understood.
大在那期，特的後石器代工具包，始於非洲北部、部及南部出。管，最近的暗示，中石器代的工具包晚很多，大在1年前，才持存在於西非。不，有此些技的古器，人知。
2. 於巴尼1具有，西非最古老之中石器代工具包的15年沉物。
150-thousand-year-old sediments at Bargny 1 that contain West Africa’s oldest Middle Stone Age toolkits.
The new study, led by scientists from the Max Planck Institute of Geoanthropology, Université Cheikh Anta Diop de Dakar, University of Sheffield, and University of South Florida, extends the timeframe in which Middle Stone Age toolkits are known from West Africa to 150 thousand years ago, based on excavations from the near-coastal site of Bargny 1.
由德克斯普朗克地人研究所、塞加喀赫安塔迪普大、英菲德大及美南佛里大，科家的新研究，根自Bargny 1近海岸址的挖掘，中石器代工具包，西非已知的，延到15年前。
“The stone tool assemblage dating from 150 thousand years ago shows classic features of the Middle Stone Age, with the use of Levallois and discoidal reduction methods and the use of small retouched flake tools rather than larger implements,” says Dr. Khady Niang, lead author of the study.
研究首要撰文人，Khady Niang博士宣：「始於15年前的石器合示了，中石器代具有使用勒瓦瓦技裁方法，及使用小型修的片工具，而不是大器具的典型特色。」
The assemblage from Bargny 1 is closely comparable to those of a similar age from across the continent, and is the first site from West Africa dating to the Middle Pleistocene, prior to the onset of substantial technological regionalization elsewhere in Africa.”
自Bargny 1的合，自此大各地，相似年代的那些合是非常似的，且是西非溯至中更新世的第一址。是在非洲其他地，始性技域化之前。
The site itself is located close to the modern coastline, south of Dakar, Senegal. While no artifacts indicating direct human engagement with coastal resources were recovered at the site, study of the associated environments offers a wider perspective.
址本身，靠近塞加喀以南的代海岸。管，在址有，示人直接涉及沿海源的人工品。不，合了境的研究，提供了一更的洞察力。
“We found mangrove and brackish wetland plant microfossils associated with the site’s occupation,” adds Dr. Chris Kiahtipes of the University of South Florida, co-author on the study. “This is particularly interesting because it shows that the site was located near an estuary and demonstrates how important these habitats are to humans past and present.”
研究合撰人，南佛里大的Chris Kiahtipes博士附言：「我了，址期有之及水地植物的微化石。特引人感趣，因它示了，址位於一河口附近，且明了些息地，人去及在是多重要。」

自 Bargny 1的花粉，包括Avicennia(部)及Typha(底部)，明於去，址河口境的接近程度。刻度25微米。
Pollen from the Bargny 1 including Avicennia (top) and Typha (bottom), that demonstrate the proximity of the site to estuary environments in the past. Scale is 25 microns.
The study highlights the long-term durability of core elements of Middle Stone Age toolkits in West Africa without evidence for the appearance of specialized technological developments observed elsewhere.
研究了，於西非中石器代工具包之石核成部分的期耐用性，有在其他地被察到，出化技展的。
“Middle Stone Age populations adapted to a wide range of habitats and engaged with climatic changes across Africa. But in West Africa, we see considerable environmental stability over the past 150 thousand years,” adds Dr. Jimbob Blinkhorn.
Jimbob Blinkhorn附言：「中石器代的族群了泛的息地，且非洲各地的候化交。不，我了，在西非去15年，相大的境定性。
One explanation for the enduring cultural continuity we observe is that it was a stable behavioral adaptation to stable environmental conditions, whilst potential isolation from other populations across Africa may have led to demographic stability too. Ultimately, our study helps illustrate the persistent utility of Middle Stone Age technologies to inhabit the diverse habitats found across Africa.”
我察到之持久文化性的一解是，它是定之境件的定行，而非洲各地之其他族群的在隔，也可能曾致人口的定性。最，我的研究有助於明，中石器代之多技，在非洲各地被，存在於不同息地的持用性。」
