Here’s this week’s practice question, we’ll be posting the answer tomorrow. Choose the option that best answers the question. Good luck!
Intelligent people are often said to have big brains. This should not be taken literally. If brain size were the cause of intelligence, we should expect elephants to be the planet’s smartest creatures. Rather, our intelligence is a result of the dense and complex neural network of the human brain. The disproportionately large human brain is no accident, however: the constancy of cell size means that a certain cranial capacity is necessary. Indeed, a large cranial volume is paramount to allow for an advanced neural network to develop. Brain size should thus be considered a prerequisite for intelligence rather than its cause.
