I'm a little confused because it's been proven that some places in the world have people with bigger skulls and bigger brains than other parts of the world.
Why is this and does this mean that the theory of evolution is true? also does this mean that some parts of teh world are more smarter than others? pls clarify as i'm really confused

No, the size of the skull and intelligence are not related. We only use a fraction of our brain, if we used it all, imagine how smart we could be.

What you are describing sounds like phrenology, which is a pseudoscience that says the structure of the skull determines a person's character and mental capacity. There's no evidence of this at all.
Brain size basically doesn't matter for intelligence. How do you define and accurately measuring intelligence among animals, particularly among humans with different educational and cultural backgrounds? Also, there is the functional diversity and connectional complexity of the brain to consider.
So, the answer is no - intelligence is not measured by brain size (unless there is some pathology like microcephaly). It also does not validate any sort of evolutionary theory - one race is not "smarter" than another race.

All these answers are ideologically skewed. This is not the social science section, people. Brain size to intelligence is mildly correlated at approximately 0.04%. Not large, but significant. Homo erectus had a 900cm^3 brain to our 1400cm^3 brain, at about same body to brain ratio. This nonsense about Einstein having a small brain, is just that; nonsense. In reality his visio-spacial area was much enlarged. Brains are expensive, though, so a smaller brain that was intelligent as a larger brain would be more efficient.

Sometimes brain weight divided by body weight is used as a rough mesure of intelligence. But, larger people generally have larger brains, but the ratio is the same as for smaller people with smaller brains. One important thing in intelligence seems to be the height and depth of the gyri and sulci in the brain.

that's likewise a shown reality that IQ has surely no longer something to do with intelligence, or a persons' skill and determination to achieve success. many human beings in this international have particularly extreme IQ rankings and fail miserably in all factors of existence. As a former instructor, i'd rather have a baby in my classification who's what's seen "extreme functioning" and especially inspired, than a baby with an particularly extreme IQ. i hit upon your question to be racist and ignorant. to assert that African-human beings have a multiple head length is ridiculous. everybody has a multiple head length than yet another. to assert that a low IQ makes someone liable to a existence of crime is likewise a tragic fact. I taught many pupils with and IQ below ninety and not one regarded "destined" to be a criminal- it became particularly the option. They were sweet-natured, threat free beings.

Intelligence is not related to brain size. And skull size is not really related to proving or disproving evolution.
Intelligence is caused by thinking, learning, and doing. People who don't do those things, no matter how big their heads, will be dummies.

according to research the size of the brain has no real effect on intelligence...from the research done so far there are no real clear answers but the most "intelligent" (whatever that is) people have had normal or less than normal sized heads and brains.*

no actually what it matters is that your furrows in your brain the foldings of your brain-namely gyri & sulcus, gyri is upword foldings & sulcus is the downword flodings. It increases your capacity to hold things & memorise. Normally every human beings is having a cranial capacity of 1.6 litres. so nothing to worry about it. If you develop your mentality you can over come those specifications easily

not at all. einstein had a really small brain actually. brain size had nothing to do with intelligence.

No. Intelligence is not correlated with the head size.
