I suspect that the vast majority of our intelligence is not emerging from our evolved state as Homo sapiens on its own, but lies in our preservation of knowledge that we built on through history.
What if we removed that preset knowledge?
A young human specimen that was separated from civilization at a young age and was raised by wild animals. One of these supposedly died in captivity after being rescued, without developing signs of a civilized human, and one other managed to learn to speak but with intense help of other civilized humans.
Now say that you remove all traces of humanity from Earth, or find a very similar planet but where humans never developed. Maybe travel in time and make sure for humans or any other humanoid creatures to be extinct up to this point. The point is, a replica of this world but without humans in its history.
Now lets say you drop young human children all around the world, among pacts of all sorts of animals, preferably primates or at least mammals. This is a generation zero. Lets say enough of these groups of these humans survive all around the world to ensure that some will come to reproduce together to secure future generations.
How long will it take for them to reach the current state of technology? For their world to look something like this?
What are their actual odds of them coming to join together in their own groups and separate themselves from their initial animal groups, rather than just going extinct? (Based on the number of younglings we decide to spawn and their relative ages)
I suppose that we are basically the same as the Homo sapiens that emerged 200,000 years ago? Which would make the history repeat itself and we would slowly discover new technologies and develop language?
But these "spawned babies" are not born in the wild as the first humans of our species,
(Lets suppose they grew in a laboratory on a interstellar/timetravelling spacecraft, in tubes that simulate a friendly environment for their growth until mature enough to have at least some chance to survive this scenario as individuals in a pact of unknown animals, whatever scenario suits you to start the generation zero going)
And I'm not sure but I think this does not matter in the long run.
I think that it should be no different from the moment that we as a species appeared in our history for the first time. Only difference would be that there would be some time before humans join in their own pacts and abandon their surrogate animal parents, but that should be resolved before the end of generation zero if we don't want them to go extinct? Can you give me reasons to support or reject this conclusion?
Which makes you think, what if all the previous species of humanoids were just tests dropped on this planets like this, but later wiped out so that the final model of humanoids, homo sapiens, can start inhabiting this planet? Or those tests of extinct humanoids were purposely built that way to make us think evolution took place, when instead, we are just an experiment of an advanced alien race.
I'm looking for any ideas, arguments or propositions that can help work out this scenario.
