Evolution of human Intelligence Feb. 23rd, 2013 @ 10:18 PM Reply

Please read all of the bellow before posting.
I was thinking... sense the creation and advancement of organized societies, has the rate in which traits of increased intelligence spread among the human population Increased? Causing an increase of the speed of evolution of human Intelligence?

For the first generation of humans "survival of the fittest" was much more relevant than it is for humans now. Humans would have to be instinctual, healthy, fit and relativity smart to survive at all. When the first civilization was established, did it become easier for more intellectual humans, who may of lacked in other attributes, to survive and spread their genes? Does education positively affect the intelligence of a person's offspring? (To really get a solid answer you would have to do advanced studies in the field of epigenetics, but I think it will be proven soon.) Would this mean that as a civilization advanced, so did the evolution in intelligence of it's population?
Then again, societies also make it easier with people of lesser traits to survive as well...
Are there just too many variables that makes this assumption too simple to be true?

Now you may think intelligence is not at all gene related, but in order for evolution to be the cause of increased intelligence in animals, it has to be. If you disagree that the theory of evolution is correct then there really isn't much to talk about. Also this was just a thought I had, I didn't really research it much before posting. It's all theory.

I'm not sure, but I think Humanity's intelligence as a whole had been around the same with a few changes here and there such as certain trees of DNA dieing out, but the reason they weren't quick to invent as present-day Humanity is today, is, well, franly, they honestly didn't know about the wonders stuff like Iron and medicine could bring to Civilization, most people didn't even know about these resources back before they existed. Humanity back was also worried more about staying alive and passing their genes rather than spending several hundred years trying to figure out the outlines of Mathmatics. We weren't ready for it yet.... or something along those lines.

I am concerned that human intelligence may be a fleeting harmonic in evolutionary patterns because it threatens its own sustainability. One of many examples: as time goes on, weaponized technology is becoming easier and easier to create and possess. This is inevitable with the progression of human intelligence.

As far as we know, we are the only planet with intelligent life. I think that since we can't find intelligence anywhere else in the cosmos that it's important that we take care of it, and spreading life to further reaches should probably be our #1 priority until we can guarantee life's protection from self destruction.

In the long run though, we will probably learn that life is an agent of entropy and that ultimately our existence will bring the universe to a quicker demise. Maybe intelligent life will be around to be pissed off about that.

Intelligence is incredibly good for survival, so id be pretty certain that the people who had evolved to have higher intelligence spread really fast and survived a lot better. It probabably happened relatively fast too.

Well this could go ether way, the spread of life throughout the universe would or destruction of life by its own hands, but honestly I doubt earth will actually be destroyed by human war. Like someone is actually going to decide to destroy the planet and them-self in the name of war?

In the long run though, we will probably learn that life is an agent of entropy and that ultimately our existence will bring the universe to a quicker demise. Maybe intelligent life will be around to be pissed off about that.

The human brain has remained relatively unchanged in the last 1000 years. 1000 years is nothing on the scale of evolution.

For the first generation of humans "survival of the fittest" was much more relevant than it is for humans now. Humans would have to be instinctual, healthy, fit and relativity smart to survive at all. When the first civilization was established, did it become easier for more intellectual humans, who may of lacked in other attributes, to survive and spread their genes? Does education positively affect the intelligence of a person's offspring? (To really get a solid answer you would have to do advanced studies in the field of epigenetics, but I think it will be proven soon.) Would this mean that as a civilization advanced, so did the evolution in intelligence of it's population?

We've reached a point where survival of the fittest is almost entirely irrelevant. This could theoretically put a halt to human evolution.

The intelligence of the average human could still rise or fall. it would all go down to non-natural-selection factors. Such as: is it more likely for a mutation to occur which lowers someone's intelligence or raises it? Is there, on average, a mismatch between the intelligence of mating pairs? Do external factors such as radiation and disease genetically or non-genetically lower intelligence?

Are there just too many variables that makes this assumption too simple to be true?

Probably not.

In terms of survival and being in tune with Nature, we are very dumb now and have regressed.

Wild dogs and wolves are two different things

Wild dogs are pretty much domestic dogs that have lived in the woods for a few generations

A really weak wolf with blunt teeth

And even if it was a wolf, there are still lots of people who can take a wolf 1-on-1

Really depends on the kind of wolf and the person doing it though.

Wolves or dingos would makes sense. A wild/stray dog I'd just rub its belly and give food.

Dingoes really aren't very large, plenty of other domesticated breeds are more dangerous.

Intelligence primarily facilitates social constructions likely to be universal, and moreover you'd have to prove differences resulted from selection instead of founder effects, drift and the like. I wouldn't worry about it.

^ Actually the process of evolution is fact

You're thinking of evolution as the causative mechanism for human existence

A couple of thousand years mean nothing to Mother Evolution. We're not that different from our cave men ancestors 4000 years ago, genetically speaking of course.

I'm not so sure. Evolution happens trough mutations but they can be very subtle. Mutations happen instantly to one creature. It just takes very long for a "helpful" mutation to spread in a population Humans breed much much faster then they did back in the day. Unique genes can now be spread all over the planet and with incredible speed. (compared to the past)
I mean imagine back then, how many populations where mostly inbred? Evolution is a process that starts with the individual. Human inventions and life style could really have a an effect on this.
And epigenetics points to the explanation that our actions in life actually directly effect the genes of our offspring. Which means public education and resources for information such as the internet, could actually cause the next generation to be smarter.
I'm not saying its causing us to naturally become super intelligent, just a slight increase in the speed of which the genes for intelligence will spread..

The overall speed of everything seems to be increasing constantly, as is human efficiency, but as for intelligence? Have we really become smarter? The way we live seems to contradict that theory.

Couldn't agree more. If modern society ever collapses, people are going to die like flies, especially in the cities. Even if there were natural resources enough to tend to everyone the smarter individuals, those who have adapted well to modern day life, wouldn't know what to do with them.
