It is widely accepted that the stereotype is indeed true: Women do tend to talk more than men. In fact, women speak an average of 20,000 words a day, as opposed to men, who speak an average of 7,000 words a day. Furthermore, it is widely known that women tend to develop language skills earlier than young boys. But what might account for this? According to a recent study, published in The Journal of Neuroscience, the brains of females "contain higher levels of a protein produced by a gene that's partially responsible for our ability to vocalize"(Miller, 2013). The protein, known as FOXP2, has been studied in the brains of rats. While female humans tend to have more of it in their brains than male humans, this protein tends to exist in higher concentrations in the brains of male rats than female rats. It is because of this protein, researchers believe, male rat pups, when separated from their mothers, emit twice as many vocalizations as female rats. In the case of humans, women have 30% more of the protein in their brains than males do.

The finding is important, but researchers wisely warn against any hasty generalizations based on this: "Scientists cautioned that we still have far to go in understanding how the gene might affect human speech, in conjunction with other brain functions. The co-discoverer of FOXP2 said it is impossible to draw "big conclusions about human sex differences" from one small study, according to ScienceNOW"(Miller, 2013).
