Researchers at University of Maryland in United States have found that a protein known as Foxp2 was responsible for making women more talkative than men.
According to recent claims, women tend to talk about 20,000 words in a day, over 13,000 words more than men. However it seems as if women are built that way after researchers found that they had higher levels of Foxp2 protein, also known as the language protein, in their brains compared to men.
AdvertisementThe researchers conducted the study in a group of rats, where they separated the mother from her four-day old pups and found that male pups were twice as vocal in calling out for their mothers compared to female pups and when they were reunited with their mother, she tended to make fuss about her sons first.
On testing the part of the brain associated with vocal calls, the researchers found that the male pups had higher levels of Foxp2 protein compared to female pups, a scenario that is reversed among humans.
"Based on our observations, we postulate higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex", lead researcher Margaret McCarthy said. The study has been published in the Journal of Neuroscience.
