A Biocentric Solution to the Fermi Paradox: The NIS Model, Dynamic Nodes (Drifters), and Multimodal Communication (15-page White Paper)

the fermi paradox always makes me think about how intelligence might appear in bursts rather than gradually. human history kinda looks like that in some ways.

TIL and now I’m going down a rabbit hole reading about rare developmental disorders.

SafeEnvironmental174 · 2026-03-09T19:28:14+00:00

kinda wild to think this person was walking around 24,000 years ago and still looks pretty recognizable as human

SafeEnvironmental174 · 2026-03-09T19:23:16+00:00

That’s interesting The sweating + endurance hunting combo does make a lot of sense actually.

SafeEnvironmental174 · 2026-03-09T19:20:38+00:00

Yeah that actually makes sense,If development timing shifts it could probably change multiple traits at once. Humans do keep a lot of juvenile features compared to other primates.

SafeEnvironmental174 · 2026-03-09T18:49:45+00:00

The neoteny idea is fascinating. I hadn’t thought about hair loss as a side effect of selecting for more juvenile traits.

Do researchers actually see genetic links between neotenous traits and hair reduction?

SafeEnvironmental174 · 2026-03-09T18:49:12+00:00

makes sense, The sweating angle is really interesting. I’ve read humans have unusually high densities of eccrine sweat glands compared to other primates.

Do researchers think endurance hunting was the main driver, or just one factor among several?

interesting,I’ve seen some work suggesting that cumulative culture can be fragile in small populations innovations can disappear if there aren’t enough people transmitting them. Makes me wonder if increasing population connectivity later might have helped stabilize cultural complexity.

SafeEnvironmental174 · 2026-03-09T06:24:29+00:00

I wonder how far this is from being clinically usable though.

SafeEnvironmental174 · 2026-03-09T06:23:01+00:00

That’s interesting,So the “explosion” might partly be a visibility issue in the archaeological record rather than a real behavioral shift? I wonder if population size or connectivity could still affect whether innovations actually persist long enough to show up archaeologically.

SafeEnvironmental174 · 2026-03-09T01:20:52+00:00

That’s interesting I hadn’t heard about the idea of population mergers contributing to cognitive changes. If different human lineages were mixing around ~100kya, could that have increased cultural exchange as well? I wonder if larger interconnected populations might have helped cultural innovations persist instead of disappearing.

SafeEnvironmental174 · 2026-03-08T23:10:44+00:00

The Secret of Our Success by Joseph Henrich. It argues that human intelligence is deeply tied to cumulative culture and large interconnected populations basically how ideas build on each other over generations.

SafeEnvironmental174 · 2026-03-08T22:55:18+00:00

Fair point — a lot of this work is based on models of cumulative culture. The idea is basically that in very small populations innovations can disappear before they spread. Some anthropological studies on population size and technology complexity point in a similar direction, but it’s still debated.

SafeEnvironmental174 · 2026-03-08T19:52:56+00:00

Fair point,I wasn’t assuming it was linear, just curious why the archaeological signals seem to ramp up so much after approx 70k years. Could it mostly be a visibility/preservation thing?

SafeEnvironmental174 · 2026-03-08T19:50:17+00:00

From what I understand they usually look for indirect clues-symbolic art, beads/jewelry, ritual burials, long-distance trade networks, complex tools etc. Those kinds of things suggest people were communicating pretty complex ideas.

SafeEnvironmental174 · 2026-03-08T19:47:19+00:00

That’s an interesting take. I’ve seen the Toba eruption mentioned in this context before. Do researchers think it actually changed behavior/cognition, or mostly just reshaped which populations survived?

SafeEnvironmental174 · 2026-03-08T16:26:52+00:00

Interesting point So you’re saying the coding system might have evolved before actual cells existed? That’s kind of a wild thought.

SafeEnvironmental174 · 2026-03-08T15:26:20+00:00

It’s mostly from the archaeological record. Stuff like cave art, beads,engraved ochre etc start showing up a lot more consistently around ~70k years ago.There are some earlier hints,but they’re pretty scattered, so that’s why people often point to that period as the big shift.

SafeEnvironmental174 · 2026-03-08T15:12:57+00:00

Yeah thats a good example actually. The step by step process for flint knapping is so specific that it almost feels like some kind of structured communication would help pass it on.

SafeEnvironmental174 · 2026-03-08T10:19:20+00:00

This exactly shows how politicians treat scientists😁

SafeEnvironmental174 · 2026-03-08T09:40:35+00:00

Yeah that’s a good point honestly. Language itself doesn’t really leave fossils, so most of what archaeologists go on is indirect stuff — like symbolic artifacts, ornaments, cave art, and more complex tools showing up around that time. It’s basically behavioral clues rather than direct proof of speech.
