That’s not how this works. If genes are physical objects—which they are—you can only transfer stuff that's actually physical and contained within them. In other words, whatever you're moving has to be smaller than the gene itself.

And why on earth should we assume that intense drives have to be physically massive? That’s just conflating two completely different categories, which brings us right back to the same old issue—mixing up apples and oranges. To get us past this specific hurdle so we can actually discuss the bigger picture, let's look at a concrete example. It’s pretty simple: if you're missing a single gene that’s supposed to regulate another one, you end up with an uncontrolled, overpowering drive. It’s a matter of regulation, not physical scale.

Look, I figured I should probably start opening up some threads about the stuff that’s been rattling around in my head lately... maybe it'll actually be useful for someone.

Look, I’ll keep this brief, but we really need to wrap our heads around how life, biological organisms, and intelligence actually function at a fundamental level. It all boils down to the creation of specific frameworks—systems designed so that a tiny, low-energy trigger can act as a switch, either releasing or channeling massive amounts of energy, or sometimes doing nothing at all. Think about it: a microscopic shift in electrical potential within just a few neurons is enough to be the deciding factor in whether a person decides to go out and dig a hole in their backyard or just sits on the couch and does absolutely nothing. You're looking at a massive divergence in physical reality triggered by a miniscule "tipping point." People love to talk about the butterfly effect like it's some chaotic accident, but that’s not quite right here. In the context of biology, this isn't some random cosmic fluke; evolution has meticulously engineered this into a sophisticated, high-level intelligence mechanism within the brain. It's an intentional, highly structured process.

It’s the exact same principle you see when you look at computer hardware, where these tiny, microscopic voltage fluctuations within a single chip can trigger massive, sweeping changes across the entire system. That is precisely the direction modern engineering is heading—we are constantly shrinking those thresholds, driving voltages lower and lower until it becomes incredibly easy to trip the proverbial wire.

You have to look at the bigger picture here. It’s like how a massive, complex neural network isn't just some random collection of wires; it's actually built upon this intricate, underlying web of low-energy, intermediary triggers that act as the fundamental bedrock for any kind of true intelligence. Think about it like a massive power grid in a place like Chicago—you can't talk about the lights flickering in a skyscraper without acknowledging the subtle, constant shifts in voltage happening deep within the substations that keep everything stabilized. Without that foundational layer of subtle interactions constantly feeding into the system, you wouldn't have the structural integrity required for high-level processing. It's all about those quiet, low-level inputs forming the base level for everything else to emerge from.

The whole process of thinking—of actually calculating and processing reality—is supposed to happen at these incredibly low energy levels. Ideally, you’d be doing it without using any energy at all. Now, I know that sounds impossible, but it remains the ultimate ideal we should be aiming for. Think about it: if you could achieve a state of pure thought, completely detached from energetic friction, the result would be so potent it could mobilize the entire energy of the universe to do whatever it wants. That’s what we’re talking about when we discuss that omnipotent, all-powerful God.

I honestly don't even know if I can put this into words effectively. For me, everything starts out as these abstract mental concepts—just raw, swirling ideas floating around in my head—long before they ever actually settle into actual language.

Just imagine for a second—and we’ve touched on this concept more than a few times before—that we actually managed to build some kind of "universal simulator." I'm talking about a machine designed to predict every single thing that's going to happen within, say, a contained space of maybe a hundred cubic meters. Inside this little bubble, you've got everything: people, AI, whatever else you throw in there. Now, let's assume this simulator is as high-end as it gets, operating at its absolute peak by using the fundamental laws of physics to map out and simulate things like wave-particle duality and all that complex behavior.
Look, if a high-level space simulator like that messes up—even by just a tiny fraction—when calculating those minute energy spikes that trigger the switches in intelligent neural networks, the whole thing falls apart. It’s like trying to predict a massive storm based on a faulty barometer; if you get those micro-calculations wrong, your entire forecast for the immediate future is going to be completely useless. One small error in the foundation and the whole prediction model becomes total fiction.
Instead of just assuming we’re digging a two-by-two hole in the backyard, you’d think someone could actually predict whether the atom in a person's gut stays put or decides to collapse onto the floor out of nowhere, leaving us wondering where the damn hole even came from. It sounds absurd, I know, but that’s the reality of it—a tiny little flicker of electricity in a single neuron is enough to flip the script entirely, making those hundred cubic meters look like a clear blue sky one second and solid ground the next.

If you strip away the human element—if you pull out the individual consciousness or that spark of raw intelligence from those hundred cubic meters of data—you’re basically left with a closed system. At that point, a simulator wouldn't just be guessing; it would be able to map out the immediate future with terrifying precision. It’s like taking the driver out of a high-performance car; once the unpredictable variable of human intuition is gone, the physics of the machine take over, and the trajectory becomes an absolute certainty.

That whole concept could actually serve as a foundation for digging into the nature of consciousness and free will itself. Think about it: just like a high-end computer simulation, the entire universe has to somehow derive the future from the present—or even better, collapse all those infinite potential futures down into one single, unfolding moment of "now." We don't have a clue how the cosmos manages that calculation, but it feels entirely plausible to me that there’s some underlying principle at play here. It’s like there are these tiny, low-energy triggers—think of them like the small spark needed to start a massive demolition charge—that possess a sort of structural priority when it comes to "rendering" the next moment. This mechanism might be exactly what gives rise to that qualitative experience of consciousness that every single one of us feels firsthand every second of our lives.

In any case, if you really step back and look at how life functions, the absolute fundamental truth is that tiny, microscopic material fluctuations are what trigger massive, downstream physical shifts. It’s like when you trace human action all the way back to its raw biological source; you eventually end up staring at a competition between maybe two neurons, where one has a current strength just 0.01 volts higher than the other, and that minuscule difference dictates everything that follows. Think about it: an entire life-altering decision, this whole complex process of weighing options and deliberating, is essentially boiled down in the brain to a mere 0.01V margin. That tiny spark then cascades outward, mobilizing something like 1,000 kWh of energy to dig a trench, build a skyscraper, or whatever else we do in this world.

And honestly, what I’m saying about those electrical differences applies perfectly to our genetics too. A single gene can work wonders. You don't need thousands of them by count or by mass to change the game. Genes act like biological switches; they usually have their own regulatory toggle sitting right next to them, and their whole existence is basically just flipping the switches of other genes on and off.

Kenneth Cruz67 said:Totally. But does that mean instincts and drives are actually passed down through our genes? I guess my own bad luck might be 😁

Of course not... none of those things are passed down through your genes. Instincts and drives are developed and cultivated throughout your life, which means you can learn to control them just as easily.

I mean, just think about it—if you were to place a newborn baby in water, they actually swim. How on earth did they learn to do that? They were just born, so there's no way they've learned, developed, or cultivated that skill yet. It makes me wonder if they inherited the ability to swim through their genes, or maybe it's just the basic physical preconditions that allow them to float and move at all?

Stereotypical movements and behaviors are actually pretty fascinating when you really dig into them. It’s pretty obvious they get passed down through genetics, but it makes you wonder about the mechanics—how exactly are these patterns encoded into our DNA, and what does the evolutionary trajectory even look like? If I recall correctly, the entire behavioral repertoire of reptiles, amphibians, fish, and insects is almost exclusively stereotypical. Mammals, however, seem to have this extra layer of complexity, a sort of neurological override that allows them to modify and train those primal centers that would otherwise just be stuck on autopilot with repetitive, instinctual actions.

Look, obviously the baby is trying to "swim," which is really just an attempt to stay afloat because when water gets in their throat, it's uncomfortable and they want to stop it. It’s more of a sensory reaction than some deep-seated survival instinct... I mean, clearly not every single baby makes it out of those situations, so they don't all "know" how to swim.
Actually, this exact baby example proves my point... some babies end up surviving specifically because they *don't* have an innate fear of water as a baseline instinct, and that's why they manage to pull through.

I have to say, I think that's a pretty poor example to use. Babies essentially spend their first nine months living in a fluid environment, so I guess they really do have plenty of time to pick things up. 😁

Amy Howard18 said:Following that logic, it would imply that early humans lived in plenty for ages, which is why their evolution would have stalled—a claim that flies in the face of actual history. On the flip side, it would suggest that modern times (our era of abundance) shouldn't coincide with our greatest period of advancement, which is exactly when it happened... it’s just completely inconsistent reasoning when you look at how history actually unfolds.

That line of thinking is basically just a variation of the idea that conflict and war are necessary drivers of evolutionary progress, and I couldn't disagree more.

We were coasting along for a while, just playing around, and then suddenly everything went south. We hit a wall. Why?
Why on earth would anyone climb down from a tree if they were perfectly happy up there? It makes zero sense. Truly.
Maybe climate change has been playing favorites, targeting the shrubs and the weeds while leaving the trees alone. It’s all a bit skewed, isn't it? Honestly, let's just head down there and see who's still standing when the dust settles. Then we can talk.

We’re living in a high-speed environment, and honestly, that just makes evolutionary shifts happen even faster. It’s all moving at breakneck speed. War, constant conflict, any kind of chaos or misfortune—it’s all part of that volatile landscape. Everything is shifting constantly.

I have always felt that organized warfare is probably a relatively recent development in our history, and honestly, I don't think it truly existed before then. Back in the day, people likely lived in such tiny, scattered groups that a clash between two small tribes wouldn't even qualify as a "war" in the way we understand it today. It seems to me that war only became this massive, defining factor once humans actually started claiming and marking out specific territories.

Sam Martinez9 said:I'm curious about your reasoning there. Could you elaborate on that thought process?

My point was that a baby born 100,000 years ago could be raised just like any child born today. Why? Because they are still *Homo sapiens*. Genetically speaking, they are identical to us. They possess all the biological predispositions required to integrate into our modern society—to use smartphones, computers, and so on. In the exact same way, a child born today possesses every genetic predisposition needed to thrive in the world of *Homo sapiens* from 100,000 years ago.

It works the same way whether you take a child born 4,000 years ago, 2,000 years ago, or even just a century ago; we could raise them just like any modern infant born in an American hospital today.

The genetic blueprint remains the same. What a child ultimately becomes depends entirely on the environment in which they are raised.

Not true.
Homo sapiens interbred with Neanderthals later on, so a baby born 100,000 years ago wouldn't share the exact same genetic predispositions as a modern-day child.

It makes me wonder, what exactly defines a war? How many people actually need to be involved for us to call it that? If two clans of maybe 30 people fight over food or land, does that count as war? If so, those kinds of clashes might have been happening for millions of years. Even mammals today, which are quite closely related to humans, engage in similar behaviors.

Since humans have such advanced brains, our social dynamics are incredibly complex. I guess if something is that complicated, it wouldn't just be about positive connections; it probably evolved to handle negative ones too. It might have developed to help us survive within a wide spectrum of social interactions, including the more violent ones.

Back then, the population was likely so small that fighting over resources or territory just wasn't worth the effort, I suppose. We see plenty of cave paintings depicting hunting scenes, but there aren't any showing warfare, and researchers haven't found skeletal remains or debris showing weapon injuries from that era.

Real, large-scale warfare seems to only emerge within the last 10,000 years. There are several mass graves out there, and the general theory is that conflicts arose because one group would attack another to seize their women 🕺

Amy Howard18 said:What you’re saying hits home because I've always found this part of human evolution absolutely mind-blowing. If you look at the current timeline, it feels like it took us millions of years just to realize we should climb down from the trees and start living on the ground. Then, we spent another 190,000 years just figuring out how to write things down about ourselves... yet, in just ten thousand years since then, we've managed to master nuclear energy and launch ourselves into space. It honestly sounds completely unrealistic... there's definitely something broken in that timeline!

I agree, it really is fascinating. The prevailing theory suggests the answer lies in sheer numbers and cooperation. For hundreds of thousands of years, humans were few and far between, scattered across the landscape, which made it impossible to collaborate or exchange complex ideas. It wasn't until the population hit a certain critical mass that civilization became possible—leading to the division of labor, contact with other groups, the exchange of concepts, wars, and trade. It's likely no coincidence that we are seeing our greatest advancements right now, precisely because we are also at our most populous stage in history.

Megan Gray32 said:I want to emphasize that second paragraph. This is something that genuinely gets under my skin—I can't quite tell if what you've provided is meant to be an explanation, a personal stance, or merely a theory you're describing as we talk, but these are thoughts that a wild animal—say, a tiger—would express with equal clarity if it possessed the gift of human speech.

That is precisely part of what haunts me—something that develops within a person and has absolutely nothing to do with humanity or being civilized, even before this whole discussion even began.

It is something entirely primal and raw, which manages to find its way into the modern world, persisting even through our most complex linguistic terminology.


I was so stunned by that I practically froze.

Also, I totally disagree with the idea that people don't feel the weight of power when they grab it. Or that those who *don't* feel the burden are just rare exceptions. Marcus Aurelius wasn't some freak occurrence. There have been plenty of people like that throughout history.

Is there any geological or climatic record in Earth's history that actually supports this idea? I mean, climate is almost always some kind of localized phenomenon, whereas this famous "descent from the trees" seemed to happen simultaneously across pretty much every location at once.

Dynamic circumstances are a constant through all of time and every era... you can't realistically measure the exact volume of that dynamism. Too much volatility can wipe out an individual entirely, which happens all the time in nature.
A war that pushes that level of intensity to its absolute limit would most likely just result in the extinction of the species.

Kenneth Cruz67 said:That’s actually why I was asking, because 😉

Quincy:
But if the question is whether instincts themselves are inherited, then I suppose the answer is a definite yes.
I guess I'm just wondering about the actual mechanisms behind that?

It isn't really about mechanisms. Bringing a mechanistic or reductionist mindset to this is like trying to understand a symphony by analyzing the chemical composition of the violin strings—it’s just the wrong lens to use. We're looking at the classic old debate regarding the whole versus its parts. Instincts emerge from the protein synthesis code, sure, but knowing the mechanism doesn't actually answer the underlying question. Essentially, the question itself is flawed.

Look, we’ve had massive climate shifts before. There's plenty of geological data and fossil evidence out there to prove it. Just do a quick Google search; you'll find some fascinating stuff. There are even great documentaries on the subject that lay out the theories and assumptions supporting those claims.
We also have to admit that these interpretations are simple, beautiful, elegant, and logical... it would be a real shame if they weren't true.

Someone always survives—at least, that's been the pattern so far. And the one who makes it through is either incredibly lucky or has an ace up their sleeve.

But there has never been a period of truly uniform global climate change that hit every single continent identically—at least none that we have records of—and humans seem to have been present across all parts of the planet (obviously not in equal numbers) since the beginning.
The flaw in your logic becomes pretty obvious when I ask this:
How did one Native American ancestor "just know" to migrate at almost the exact same time as his colleague in Africa? You can't claim it happened because the climate conditions in Australia and Africa were identical, because the geological and climate records for those two continents don't support that at all.

In the event of a nuclear holocaust—which is really the only realistic scenario if we ever face another major global conflict—nobody survives. Or rather, any survival on an evolutionary level would likely be reduced to a primitive state, perhaps even down to the very beginnings of life itself... from which a being called *Homo sapiens* might not necessarily re-evolve through a similar process.

The idea that a Native American ancestor just happened to decide to climb down in the US is fundamentally incorrect. If you actually look up human evolution on Wikipedia, you'll see how the timeline really worked out.

To put it simply: all humans share a common ancestor, and that ancestor lived in Africa. That's where the transition from the trees happened. Many years later, that ancestor's descendants migrated across the globe, spreading to every continent, including North America.

Okay, so maybe using Native Americans in the context of "descending from trees" isn't the best way to frame this... let me try to put it this way instead. Based on various DNA analyses, there were populations in many other parts of the world—take Asia, for example—who developed independently from the original African ancestor, and this evolutionary path happened during almost the exact same timeframe. Later on, those lineages, which had evolved autonomously in Asia, eventually migrated to Australia, and it was from those groups that the aforementioned Native Americans descended.
