  Archaeologists have discovered the world’s oldest known cave painting: a life-sized (艺术作品)与真人[实物]一样大的 picture of a wild pig that was made at least 45,500 years ago in Indonesia.


  The finding, described in the journal Science Advances on Wednesday, provides the earliest evidence of human settlement of the region.

  周三发表在《科学进展》(Science Advances)杂志上的这项发现,提供了该地区有人类定居的最早证据。

  Co-author Maxime Aubert, of Australia’s Griffith University, told AFP it was found on the island of Sulawesi in 2017 by doctoral student 博士生 Basran Burhan, as part of surveys the team was carrying out with Indonesian authorities.


  The Leang Tedongnge cave is located in a remote valley enclosed 围绕 by sheer limestone cliffs 石灰岩悬崖, about an hour’s walk from the nearest road.

  Leang tedonggge洞位于一个偏远的山谷,四周都是陡峭的石灰岩悬崖,距离最近的公路步行约一小时。

  It is only accessible 容易到达的 during the dry season because of flooding during the wet season – and members of the isolated 孤立的;分离的;绝缘的;单独的 Bugis community told the team it had never before been seen by westerners.


  Measuring 136cm by 54cm (53in by 21in), the Sulawesi warty pig was painted using dark red ochre 赭色 pigment and has a short crest of upright hair, as well as a pair of horn-like facial warts 疣 characteristic of adult males of the species.


  There are two hand prints above the pig’s hindquarters, and it appears to be facing two other pigs that are only partially preserved, as part of a narrative scene.


  “The pig appears to be observing a fight or social interaction between two other warty pigs 疣猪,” said co-author Adam Brumm.


  Humans have hunted Sulawesi warty pigs for tens of thousands of years, and they are a key feature of the region’s prehistoric artwork, particularly during the ice age.


  Aubert, a dating specialist 年代测定专家, identified a calcite deposit 方解石沉积层 that had formed on top of the painting, then used uranium-series isotope dating to confidently say the deposit 沉积层 was 45,500 years old.


  同位素地质年代学(isotope chronology)又称同位素年代学,是同位素地质学分支之一。利用自然界放射性衰变规律研究测定各种地质体的形成时代的同位素记时方法。

  This makes the painting at least that age, “but it could be much older because the dating that we’re using only dates the calcite on top of it”, he explained.


  “The people who made it were fully modern, they were just like us, they had all of the capacity and the tools to do any painting that they liked,” he added.


  The previously oldest dated rock art painting was found by the same team in Sulawesi. It depicted a group of part-human, part-animal figures 半人半兽的人物  hunting mammals, and was found to be at least 43,900 years old.


  Cave paintings such as these also help fill in gaps about our understanding of early human migrations.


  It is known that people reached Australia 65,000 years ago, but they would probably have had to cross the islands of Indonesia, known as “Wallacea”.


  This site now represents the oldest evidence of humans in Wallacea, but it is hoped further research will help show people were in the region much earlier, which would resolve the Australia settlement puzzle.


  The team believes the artwork was made by Homo sapiens 智人(现代人的学名), as opposed to now extinct human species like Denisovans, but cannot say this for certain.


  To make handprints 手印, the artists would have had to place their hands on a surface then spit pigment 颜料 over it, and the team are hoping to try to extract DNA samples from residual saliva.
