Abstract
Previous dating research indicated that the Indonesian island of Sulawesi is host to some of the oldest known rock art1,2,3. That work was based on solution uranium-series (U-series) analysis of calcite deposits overlying rock art in the limestone caves of Maros-Pangkep, South Sulawesi1,2,3. Here we use a novel application of this approach—laser-ablation U-series imaging—to re-date some of the earliest cave art in this karst area and to determine the age of stylistically similar motifs at other Maros-Pangkep sites. This method provides enhanced spatial accuracy, resulting in older minimum ages for previously dated art. We show that a hunting scene from Leang Bulu’ Sipong 4, which was originally dated using the previous approach to a minimum of 43,900 thousand years ago (ka)3, has a minimum age of 50.2 ± 2.2 ka, and so is at least 4,040 years older than thought. Using the imaging approach, we also assign a minimum age of 53.5 ± 2.3 ka to a newly described cave art scene at Leang Karampuang. Painted at least 51,200 years ago, this narrative composition, which depicts human-like figures interacting with a pig, is now the earliest known surviving example of representational art, and visual storytelling, in the world3. Our findings show that figurative portrayals of anthropomorphic figures and animals have a deeper origin in the history of modern human (Homo sapiens) image-making than recognized to date, as does their representation in composed scenes.

有說20萬年前出走非洲,也有說6萬年的。我在網上查了一下,基因出走理論那個亂呀,各說各話,可見邏輯混亂。 -郭大平- 給 郭大平 發送悄悄話 郭大平 的博客首頁 (0 bytes) () 09/05/2024 postreply 11:21:16

線粒體夏娃,Y染色體亞當,都是靠不住的,隻是一種可能性,不過可能性可能較高而已。根據基因的多樣化程度來判定,本身不可靠。 -郭大平- 給 郭大平 發送悄悄話 郭大平 的博客首頁 (0 bytes) () 09/05/2024 postreply 11:23:45

也就是說,DNA 鑒定親子的準確率,怎麽也達不到100%。那麽,根據基因鑒定,得出世人都來自非洲父母,其準確率就更堪憂了 -郭大平- 給 郭大平 發送悄悄話 郭大平 的博客首頁 (0 bytes) () 09/05/2024 postreply 12:14:08
