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.

“出非洲说”是主流学说,也有“出东亚说”。

现代人类走出非洲是六万年前开始,并不是一次而已

还有来自姆大陆说。。。。。
晚春就是牛
智人出走在大约距今12万5千年到六万年间离开非洲大陆

有说20万年前出走非洲,也有说6万年的。我在网上查了一下,基因出走理论那个乱呀,各说各话,可见逻辑混乱。

线粒体夏娃,Y染色体亚当,都是靠不住的,只是一种可能性,不过可能性可能较高而已。根据基因的多样化程度来判定,本身不可靠。

20万年前智人母亲才出生,智人在非洲混了十四万年才开始出走非洲

现在基因技术已经可以很快找出DNA核苷酸排列次序,然后用电脑高速比较可以得出智人如何迁移的

维基百科:DNA亲子鉴定,否定亲子关系的准确率几近100%,肯定亲子关系的准确率可达到99.99%。

玩文字游戏?维基百科说的是全文?
郭大平
也就是说,DNA 鉴定亲子的准确率,怎么也达不到100%。那么,根据基因鉴定,得出世人都来自非洲父母,其准确率就更堪忧了

因为首先“四万年前”这个数字就是错的!
波粒子3
99.99%的准确率被你说成准确率堪忧,数学是从体育老师学的?
哪一枝杏花
人类有没有DNA是从狗身上来的?或者海豚?
波粒子3
答案没有这么简单,物种经过上亿年的进化,DNA进化的不一样
