Wait, why couldn't the Indonesians migrate to Europe in a span of 20,000 years.

Wait, why couldn't the Indonesians migrate to Europe in a span of 20,000 years.
- mseepgood 2y agoGoogle Maps says it takes about 5 months on foot from Borneo to Lascaux. So it could have been the same person who left at New Year's and was back home by Christmas.
- tim333 2y agoPlus you'd need a boat. Borneo is about a hundred miles from the mainland.
- bleuarff 2y agoNot sure that was the case 50ky ago. That was during a glacial period, sea level was probably 100+m below current level.
- nkrisc 2y agoNo, not in the general timeframe being discussed. Most is SEA was connected by land to continental Asia. Even North America and Asia were connected by Beringia. It’s possible you could have even walked to Australia from Asia, though I might be mistaken about that.
- doitLP 2y agoSure with excellent roads and 99% of predators gone and most importantly, a reason to do it.
- aksss 2y agoPredators including the human variety.
- nkrisc 2y agoI’m not aware of studies involving radiocarbon dating of paved roads, so I can’t say conclusively, but I believe the leading hypothesis is that they didn’t exist 50,000 years ago.
- croisillon 2y agosome kind of exchange program for artists to residence in various places in the world, i like your hypothesis!
- dekhn 2y agoIt's not impossible, but the mainstream theories such as 'Out of Africa' and most anthropological evidence suggests that the flow was from Africa to Indonesia and Africa to Europe, and not "back from Indonesia". But see https://en.wikipedia.org/wiki/History_of_Indonesia https://en.wikipedia.org/wiki/History_of_Indonesia and https://en.wikipedia.org/wiki/Polynesia#History https://en.wikipedia.org/wiki/Polynesia#History and https://www.nytimes.com/2020/07/08/science/polynesian-ancestry.html https://www.nytimes.com/2020/07/08/science/polynesian-ancest... as well as https://en.wikipedia.org/wiki/Multiregional_origin_of_modern_humans https://en.wikipedia.org/wiki/Multiregional_origin_of_modern... Europe is mostly believed to have been settled via Africa, the Middle East, and Western Asia. https://en.wikipedia.org/wiki/Genetic_history_of_Europe https://en.wikipedia.org/wiki/Genetic_history_of_Europe (I am absolutely amazed by all the various humanity and technology origins. It's almost as if there is a direct path from the first person who used teeth and fingernails to pry a rock and fiber to make a spear to kill an animal and use its bones to make high quality tools for knapping stone, all the way to the lathe, which was the tool that bootstrapped the industrial revolution).
- lukebuehler 2y agoI've never heard of the idea that the lathe bootstrapped the industrial revolution. Can you say more, and any pointers to read?
- rdlw 2y agoThere's a great Machine Thinking video about the history of the lathe that makes this point: https://youtu.be/djB9oK6pkbA https://youtu.be/djB9oK6pkbA
- dekhn 2y agoI'm not sure there's any really good book that furthers this argument (possibly The Perfectionists or One Good Turn?) but it sort of becomes obvious when you read about Maudsley (https://en.wikipedia.org/wiki/Henry_Maudslay https://en.wikipedia.org/wiki/Henry_Maudslay and https://en.wikipedia.org/wiki/Screw-cutting_lathe https://en.wikipedia.org/wiki/Screw-cutting_lathe) and Wilkinson (https://en.wikipedia.org/wiki/John_Wilkinson_(industrialist) https://en.wikipedia.org/wiki/John_Wilkinson_(industrialist) and https://en.wikipedia.org/wiki/John_Wilkinson_(industrialist)#Cannon_boring_machine https://en.wikipedia.org/wiki/John_Wilkinson_(industrialist)... the cannon boring machine was what enabled the efficient steam engines which unlocked large mechanical shops (along with high quality cannons), while the lathe enabled precision machine tool making. I am sure many things had to happen around the same time for the revolution but IMHO the lathe was the true linchpin
