    Does anyone know any good books on the subject?

    None I wasn't arguing against that point.


    ...Well it requires intelligence and stamina if you're an illegal immigrant.

    Going by the Holy Bible, the first humans were created on October 9, 4115 BC. Of course people have gotten stupider since then. Most don't even know that date.

    The people of the bible were many times extremely smart and insightful.

    Its also valuable to add in this debate that most people from today would be considered severely handicapped and stupid 200 years ago, 100 years ago, 500 years ago, 1000 years ago.

    With a few exception, for example people with knowledge that is "timeless", example engineers, doctors, philosophers, astronomers and so fourth. Even though they would face severe handicaps back in the days, they would manage to adapt and adapt the people around them, unlike almost everyone else who would simply die, be killed or be considered retarded, helpless, invaluable, weak and so fourth.

    A person from 200, 2000 years ago would adapt much better to current times, and have a much more diverse intelligence basis to build on than people who live now, with special knowledge which is often dependent on certain type of equipment.

    you'd think that if brain size had something ot do with intelligence we'd all be ruled by elephants or whales

    I'm pretty sure that the brain size to body size ratio is a significant factor here. In the case of humans, body size has increased and brain size is decreasing. It may mean something.

    Previously, as humans evolved from less intelligent primates, brain size increased as humans became more intelligent.

    When comparing different species the ratio of brain weight to body weight does present a correlation with intelligence, though the actual brain weight has little or no effect. For example, the ratio of brain weight to body weight for fish is 1:5000; for reptiles it is about 1:1500; for birds, 1:220; for most mammals, 1:180, and for humans, 1:50.

    Within human population, studies have been conducted to determine whether there is a relationship between brain size and a number of cognitive measures. Studies have reported correlations that range from 0 to 0.6.[2] Some scientists prefer to look at more qualitative variables such to relate the size of measurable regions of known function. For example relating the size of the primary visual cortex to its corresponding functions, that of visual performance.[3][4].

    The brain is a metabolically expensive organ, and consumes about 25% of the body's metabolic energy in some species. Because of this fact, although larger brains are associated with higher intelligence, smaller brains might be advantageous from an evolutionary point of view if they are equal in intelligence to larger brains. Skull size correlates with brain size, but is not necessarily indicative.

    Brain size is a rudimentary indicator of the intelligence of a brain, and many other factors affect the intelligence of a brain. Higher ratios of brain to body mass may increase the amount of brain mass available for more complex cognitive tasks. Brain size in vertebrates may relate to social rather than mechanical skill. Cortical size relates directly to a pairbonding life style and among primates cerebral cortex size varies directly with the demands of living in a large complex social network.[5]

    Here is a list of some species, along with their rough average brain sizes:

    * Homo erectus: 980 cm³
    * Homo habilis: 750 cm³
    * Homo floresiensis: 380 cm³
    * Homo neanderthalensis: 1200-1750 cm³ skull capacity (10% greater than modern human average, when including juvenile cranial capacity)
    * Homo sapiens: 1350-1400 cm³[citation needed]
