The remains of some of the earliest modern humans to enter Asia have been discovered in a Laos cave, according to a study published Tuesday.
Excavations in the Tam Pa Ling cave over the past seven years revealed bone fragments belonging to early modern humans who inhabited the region some 86,000 years ago, and may have lived in the mountainous area for at least 68,000 years, according to Nature. The discovery pushes back the previous timeline on the exploration of humans, as these remains may be from some of the first humans to enter southeast Asia after leaving Africa...
A small piece of skull and a shin bone fragment were uncovered in the cave, and are believed to have been deposited during a flood event. Through analysis of herbivore teeth, electron spin resonance and uranium-series dating, the researchers compared the fragments to others found nearly a decade ago in the cave, and found them to be almost twice as old.
The bones also challenge the human migration hypothesis that homo sapiens left Africa and dispersed across the planet in a single rapid event, called the Marine Isotope Stage 5, Nature noted. This time period lasted from 130,000 to 80,000-years-ago, but the discoveries in Tam Pa Ling don't align with these theories. These humans apparently left wherever they were well before the Marine Isotope Stage 5 occurred.
The shape of the fossilized remains are also throwing a wrench in our historical understanding of early modern humans. The younger skull fragment, for example, has characteristics of both modern and archaic humans, whereas those dated to around 86,000-years-ago only have modern human characteristics.

Finger fossil puts people in Arabia at least 86,000 years ago
https://www.sciencenews.org/article/finger-fossil-puts-people-arabia-least-86000-years-ago
A single human finger bone from at least 86,000 years ago points to Arabia as a key destination for Stone Age excursions out of Africa that allowed people to rapidly spread across Asia.
Excavations at Al Wusta, a site in Saudi Arabia’s Nefud desert, produced this diminutive discovery. It’s the oldest known Homo sapiens fossil outside of Africa and the narrow strip of the Middle East that joins Africa with Asia, based on dating of the bone itself, says a team led by archaeologists Huw Groucutt and Michael Petraglia. This new find strengthens the idea that early human dispersals out of Africa began well before the traditional estimated departure time of 60,000 years ago and extended deep into Arabia, the scientists report April 9 in Nature Ecology & Evolution.
Early presence of Homo sapiens in Southeast Asia by 86–68 kyr at Tam Pà Ling, Northern Laos
Abstract
The timing of the first arrival of Homo sapiens in East Asia from Africa and the degree to which they interbred with or replaced local archaic populations is controversial. Previous discoveries from Tam Pà Ling cave (Laos) identified H. sapiens in Southeast Asia by at least 46 kyr. We report on a recently discovered frontal bone (TPL 6) and tibial fragment (TPL 7) found in the deepest layers of TPL. Bayesian modeling of luminescence dating of sediments and U-series and combined U-series-ESR dating of mammalian teeth reveals a depositional sequence spanning ~86 kyr. TPL 6 confirms the presence of H. sapiens by 70 ± 3 kyr, and TPL 7 extends this range to 77 ± 9 kyr, supporting an early dispersal of H. sapiens into Southeast Asia. Geometric morphometric analyses of TPL 6 suggest descent from a gracile immigrant population rather than evolution from or admixture with local archaic populations.
Introduction
Current genetic and fossil evidence points to an African origin of Homo sapiens around 300 kyr1,2. The number, timing, and route(s) of human dispersals out of Africa into Eurasia is intensely debated (see refs. 3,4,5,6 for review) with dispersal models falling into two broad categories: an early dispersal during Marine Isotope Stage (MIS) 5 (~130–80 kyr) and a late dispersal occurring in a post-MIS 5 time frame3. Genomic evidence strongly supports a single rapid dispersal of all ancestral non-African H. sapiens populations after 50–60 kyr, followed by a divergence of descendant groups westward into Europe and eastward into South Asia1,7,8. While there is some genetic evidence supporting a separate, early worldwide expansion of H. sapiens in present-day Australasian populations (i.e., Australians, New Guineans and Asian Negrito)9,10,11,12, recent genomic studies on ancient and extant humans suggest that if there was any genetic contribution of such early dispersals to present-day populations, it was not substantial, being less than 1%13,14,15,16,17,18.

Well, what happens if they find a new site, like a cave, with remains in it they hadn’t known about before?
Should they hide it? Ignore it?
I know you’re just joking, but some people don’t understand science is based on discovery. It should, indeed must, change as new things are discovered. Even if it throws the older believes on their tail.
This is why not studying Ivermectin and writing it off as horse paste during Covid was so anti-science, even if the propagandists gaslighted us that they were “scientists”.
They weren’t.
If modern humans predate archaic humans, then maybe we are the archaic humans.
Archaic humans can survive!!!
Modern humans is a foolish term that I hope dies out.
There’s no takeaway about a flood event. If there were an ability to leach away dating evidence, it wouldn’t be possible to RC date ancient shipwrecks.
There’s an agenda at work at both ends of the Asia/Africa debate.

If there was no functional government and laws, there was nothing to be “illegal” against.
I do not think africa was THE origin of man, just had the best preserved bones.
Governor Newsome ancestor raised taxes, so they moved to a low tax area headed by Ron DeSantis ancestor! 🤓
My guess is, given that for most of the last 2 million years, the oceans have been hundreds of feet lower, and it was warmer down there on what’s now the continental shelf, most of prehistory happened there. :^)
Always humans originated in Africa.
