@antioxidants87 I also don't see how you're reading my comments as me being mad, I'm just trying to explain the concept of correlation to you - you're implying that muscle size has nothing to do with muscle strength. Look at the lifts for different weight divisions in weightlifting - it correlates with body/muscle mass. I know you can train to lift large weights without increasing muscle mass much, that doesn't mean it has 0 to do with it.
@antioxidants87 It's a fairly weak correlation between the two (0.25), so it's not everything. Yes a bodybuilder has trouble doing pullups but they have to lift far more weight doing a pull up than you or I. Lifting the same amount of weight (by bench pressing etc.) they'll most likely dominate (especially if you take large sample sizes).
I don't have a PhD, and I don't see why you're so intent on calling me stupid - I actually agree with you on a lot of points.
Brain size does not only contribute to intelligence. Are ability to see colors? Take up a hell of a lot of neurons to make. Larger muscle mass? More neurons. Having larger brains does is quality but that quality is not always intelligence. But you are pulling that out of your ass.
Are you retarded? I was talking about humans (repeated it two times), not rats vs. chimps. Slight variation of humans' brain size doesn't affect intelligence.
Nope, brain size in healthy humans doesn't correlate with IQ at all, there are Einsteins with extremely small brain volumes and extremely high brain volumes. I don't have to prove you anything nor disprove your retarded analogies, because you're nothing to me.
@alexgrinkov You can't just make claims like that without proof, when there are many studies to the contrary. You seem to fail to grasp the concept of correlations - they aren't a hard rule (unless correlation is 1.00) and may fail to predict two individuals relative IQ when someone with a smaller brain has higher IQ. But when you start comparing large groups of smaller brained people to large groups of larger brained people, the correlations predictions are more accurate.

@alexgrinkov Also why the hostile tone? You seem to have disdain for those who think differently to you - you must have tons of friends acting like that.
@alexgrinkov You are fundamentally incorrect, the same phenomena can be found within cows and sheep post domestication. The decrease in conflict and independence required to survive reduces brain size. The brain does not use all of its matter but has unused space to allow the mind to adapt to new hostile changes as an independent. Also IQ tests do not measure adaptability of the brain, but a comparison between individuals. IQ tests have not been stable and do not capture pre IQ test results.
Not surprising when we drink flouride and are exposed to various other neurotoxins everyday, and a quarter of the population is on psychotropic drugs, many of which have been linked to brain atrophy (shrinkage) - Kids with ADHD for example have statistically significantly smaller brains than average after years of amphetamine/methylphenidate use. The mental health movement is probably the leading cause of mental problems.
U tard. Intelligence is determine in the frontal lobe of Humans. I believe we shrink in other parts of the brain because we grow to be more smaller. Nothing to do with intelligence. The last sentence is probably pulled from your ass
@SgtThom Since the mental health movement has started medicating people with anti-depressants (especially SSRIs) and anti-psychotics the number of hospitalised mental patients has skyrocketed. The correlations are uncanny.
It looks like our overall brain size may have decreased, but by the looks of those early skulls, our frontal lobe has increased in size. A well developed frontal lobe is the key to intelligence.
antlantis survivor !The antlantis survivors they have the new realm of the High european land. Their normal man are ready to be kings of all bronze age and to build the news civilisations. Today, their laws of blood are dead and 50 % of all american are Big and ulgy!
sorry, I'm doing the best I can with the contents of my dumb,diminished, delicate paper thin pate, maybe I'll start wearing a helmet in case I slip on the grass and risk cracking it open like an egg--then again I don't think they make helmets that small--maybe I'll make one out of a pen cap-
So what if they had bigger brains. That doesnt mean there smarter then us. That just means our brains are more evolved. Think of it like computers. Back in the 60's they had computers as big as my house but yet my iphone is more high tec and come do more then thos computers. I willing to bet that the human brain is the same way.
Pred123424, actually, it does mean they were smarter than us, on average. This was in Discover magazine. There is a 0.40 correlation between brain size and intelligence, which is significant.
The first computers had vacuum tubes. Today's computers have transistors burned into silicon chips. The comparison is not valid.
They had larger brains because life was so challenging. Today you don't hunt, skin a deer, make your clothes or light fires to stay warm, life is less challenging.
@pred123424 It could mean that we needed less and less intelligence as our lives became more controlled and mechanical. Humans had a lot of "better" things (stronger jaws, tougher overall frame, etc.) that weren't needed anymore. Anything not needed is a waste of energy, so the individuals with less of it would have a bit more energy for reproduction...over whole populations, many generations, the "strong, but unneeded" traits disappear.
There is a simplistic argument for high efficiency engines, but somehow steam and pnumatic drive engines have been replaced with super heat chucking technology of internal combustion and always always chucking the heat. What ever happened to the steam engine? Couldn't it be modern. We are led to believe it is a "bad technology" for engines, but the truth is that it is heat recycling and hidden from common knowledge, or banished in all forms. If you wear a suit; status will only all the "quo".
Here's an intelligence based puzzle. (it's my own) Given that planets are spherical; are the likely to be solid or hollow. We are conditioned to believe they are solid, but the logic of gravity and mass seems to say they are all hollow piles of space debris. Including Earth. You can be absolutely correct in "common knowledge" but totally wrong in truth. We all kind of believe what we're told to believe on matters as "common knowledge" dictates. The "solid" argment is an angry argument.
i hate to say it, but life has become a more competitive and therefore less given to thought and more consideration is given to taking pleasure by giving pain or punishment to others. It's hierarchal in structure; You don't have to be smart if you are in a position to be cruel. Cruelty is a critical factor in survival success, hence smaller brains. No need for intelligence when being cruel. When the ability to be cruel is a measure of survival then brains will become smaller.
@hypnofan35 I've read that kindness and altruism is actually a fairly modern trait in the animal kingdom. The minority of humans are psycho/socio paths. In reptiles, amphibians, etc. psycho/socio pathy is the norm.
@karokeizhere It's not conclusive. Our brains are smaller, but he doesn't mention that they also have more involutions...more cortex (surface), which means it might balance out or it could be one way or the other. Also, language has become more important than having a brain set up for a great sense of smell (for example)...so there could be differences in what their brains were good at compared to ours.
@newguy33X i don;t know, it's probably size to body ratio, reason why our brain is goanna be chimpanzee size is because people are getting shorter. The human hobbit has a small brain because she;s a hobbit.
@BeamSurfer I'm not sure what you're refering to. Brain to body ratio is generally correlated with intelligence, but a brain can have lots of connections and surface area and be small and end up much more complex than a larger, but lower-surface area/connections brain. There's a range of nerve cell sizes (generally), like human cells in general, that can function normally. The person with the biggest brain in the world doesn't necessarily have the smartest brain. People are shorter? Hobbits?
@newguy33X Humans aren't getting shorter, btw. Americans (at least) have been getting taller over the past 200 years. Most scientists attribute that to the modern diet.
Also, you might say that the human brain is becoming more advanced, but that still doesn't explain why it would have to get smaller.
Many large old computers are much less powerful than new small ones. Do we form more engrams per cubic centimeter than our ancestors? Do we have reduced olfactory capability that requires less brain capacity? Are our brains evolving to sometimes perform quantum computing? And if so, might it take less cranial volume to perform? Do emotions integrated and embedded in computing systems simplify computation? Maybe I should watch the whole show.
we are not getting dumber as every kid gets better results as the last year groups so that proves that we are getting more clever at least that is the truth in my country
@ThomsonFly12331 this is not true, what is actually happening is the education is getting easier. The government tells the board of education they want to see more kids getting better results so instead of improving education they just make the tests easier so it seems to give better results. look at how drippy the 19-25 year olds are nowadays......it is embarrassing

brain size has nothing to do with man's intelligence. there was a documented incident of a man whose head was severely injured due to an accident. the man survived and what was left was only 10% of his brain. it was an amazing fact that, still, the man had the same mental capacity as before!
You'll note he didn't mention anything about mental capability. This data is demonstrating the continued evolution of human beings as a change in brain volume and skull thickness. Brain volume is not the only factor in how intelligent a population or indeed a single brain is.
