Someone below mentions bird poop, but could a fish egg survive the human (or a dogs) digestive system as well?

#22An alternative vector: "cloud seeding" ( https://www.theguardian.com/science/2004/sep/09/science.rese... ) Charles Fort collected numerous data for his famous "The Book of the Damned" https://en.wikipedia.org/wiki/The_Book_of_the_Damned
It rained fish in my front yard in South Carolina back in the 80's, it's definitely a real phenomenon.

#23> That is the only possible explanation for how fish could have populated isolated mountain lakes isn't that a common question? "How do fish appear in landlocked lakes/ponds/etc"? After digging a pond and letting it fill with rainwater/groundwater, fish appear. I don't think its because people carried them there. (don't really know the common answer though)
Mountain lakes are completely different. There’s fish eggs being washed everywhere during rain storms. The eggs come from upstream and wash into random places.
This doesn't provide an answer for lakes.
But I always thought the explanation was eggs randomly getting stuck to bird feet. Or maybe a bird carries a fish with eggs up there and eats it or something. Inevitably it happens though...

How did they appear upstream?
There’s a stream in my back yard that doesn’t hold fish over the winter because it’s too shallow/cold. A large property near me has a pond that overflows into my stream. The fish survive in the deeper waters of the pond and spring rain usually washes fish eggs or even fish into my stream. They gather in the rocks in my backyard near the storm drain.
Alpine lakes are fed by snow met. There’s not going to be fish eggs on the snowpack that melts into the lake.

#26Yes. One thing that becomes very obvious if you go along "native" human villages in Africa is the reason civilization develops. When you look at villages that don't grow, but do the normal human thing. Grow, war (2 kinds: young vs old and village/tribe vs village/tribe), grow. It's not because of agriculture. They have agriculture (they grow maniok, and you don't need much. They have fire, weapons, ... Also the entir…
Great point until the end. None of your descriptions imply a lack of morality for living isolated from a greater civilization. If anything, such small societies inhabit a neutral position, in that they don't care, which is something you already stated. I think the only people arguing that the North Sentinelese are immoral are religious, for instance (hence why most attempts to visit are done by missions). The general…
Well, they sure are xenophobic.

I hate how much of historical science is performed this way. Speculation is not very scientific.

#28I wouldn't be so sure. Were there ever any ducks?

> 7000 years ago is the edge of recorded human civilization (well 8000 years The earliest pre-pottery Neolithic complexes are nearly 4000 years older than that.
Did they have writing and kept records that we've found? That's the "recorded" part.
In Norway, the oldest written records are barely 1000 years old.
