What kind of flora and fauna might the first humans to arrive to the continent later on, wherever they might be from, might encounter? What would be the consequences of a mostly uninhabited Western hemisphere?
No tomatoes means no pizza, which automatically makes the world several times worse.First thought: mammoths! Second thought: no crops such as tomatoes, pineapples etc but especially maize.
Assuming discovery happens as otl, I wonder if it means Vinland survives. The Norse had problems with the natives, and iirc attacks by the natives destroyed their settlement. Without those, maybe Vinland could have been permanent.
Not to mention the Dena migration.Kind of nitpicky, but there were likely 3, and possibly 4 or more, different migrations to America, and only one of those three (albeit seemingly the most significant) was by Beringia.
Even if you somehow stop people from crossing over from Beringia, that would just mean that the continent would be settled by the (likely) earlier coastal migration. This would have enormous butterflies and result in the American civilizations being genetically, linguistically, and culturally unrecognizable to what we know, but there would still be people there and they would probably be of a similar population and probably basically similar status to Native Americans as we know them. If you eliminate this one too, then you're still left with the migration of Thule peoples circa 5,000 years ago. They would find a virgin field and settle the entire continent by the time the Europeans got a handle on things, though the butterflies would be in some sense even more extreme since the shorter timeframe will result in radically different societies in addition to the above.
Eliminating all of these, most of all the Inuit migration, seems improbable.
I doubt that pre-agricultural native Americans had such a huge impact on forests.The butterflies are massive here, because an 'empty America' scenario would have significant effects in the Earth's climate in the long term (as Native Americans deforested much of Northern America IOTL).
So we could not expect that IOTL History would run in the same way in the rest of the World.
But that's still "through" Beringia given it was coastal migrations, if he's talking about post-LGM migrations(given he said "earlier")I’m assuming he’s referring to the more recent discoveries that human settlement in the americas occurred in several stages, some of them involved coastal people sailing along the coast of Eastern Siberia into Alaska
Yep. One case of this is the Willamette Valley in Oregon where the natives (Kalapuyan-speakers) routinely set fires to maintain an oak savanna and smoke out deer and other game. Almost all of them died in epidemics or forced relocation to reservations in the mid-19th century, and by the end of the 19th century locals noted how much the local forests had expanded.They had it, same as aboriginal Australians.
People tend to underestimate the great impact of the human in the environment, even at a Neolithic level.
Exactly, this happened in many places (not only in the Americas, but in other parts of the planet).Yep.

But this occurred nearly everywhere like California, the fringes of the Great Plains, Eastern North America--humans using fire to encourage preferred plants and drive out game is an extremely old tradition.
As I understand it, the coastal migration did not go "through" Beringia, as the southern coastline of Beringia was glaciated and impassable at the time. Rather they went "by" it, and didn't physically cross it. They likely originated in Siberia proper or the Kurils before commencing their coastal migration.But that's still "through" Beringia given it was coastal migrations, if he's talking about post-LGM migrations(given he said "earlier")
