Explain one significance of an increase in the cranial capacity in the home sapiens
The size of the cranium is secondary to the real significant increase, that of neural density. The amount of neurons and neural capacity per cubic measurement denotes the intelligence potential. More neurons tends to equal more intelligence. The cranial capacity concept simply says that in a given example, with no difference in neural density, the larger the brain the better. Think of it this way....in an LED flashlight, the first models were one low powered LED that gave one small amount of light. To upgrade that for more light/more intelligence, if you had the same exact LED bulb or the same neural density, you simply added more of the same LED's for more light/more intelligence. The increase in the power of LED's, the increase in neural density, made incredibly bright LED flashlights possible. One LED today can easily give more light than a hundred of the old ones. That's why humans, with relatively small brains, can be far more intelligent than other animals even though the animals might have much larger brains. We have a higher neural density. But if all else is equal, the larger the brain, the more intelligent the creature....so cranial capacity can usually denote potential intelligence.
