Sorry to interrupt, dear, but women truly do talk more than guys (13,000 words a day more to be precise)

Ladies, the next time the man in your life complains you talk too much, muffle him with science.
Tell him – at length, of course – it is all because of the Foxp2 protein.
It has been claimed previously that women speak about 20,000 words a day – some 13,000 more than the average man.
It has been claimed that women speak about 20,000 words a day – 13,000 more than the average man – and scientists say a higher amount of the Foxp2 protein is the reason women are more chatty
But now scientists have found the key to explaining why women are the more talkative lovemaking.
A probe just published suggests that higher levels of the protein are found in the female brain.

US researchers found that those with more Foxp2, known as the ‘language protein’, in their brains were the chattier. Among humans that was women, but in rats it was the masculines.
The researchers set out to determine what might make masculine rats more vocal than their female box mates. They separated four-day-old pups from their mothers and counted the number of times they cried out.
Both masculine and female pups emitted hundreds of sobs, but the masculines called out twice as often. As a result, when the pups were put back in the same box as their mother, she fussed over her sons very first.
Researchers found the so-called ‘language protein’ that makes women more talkative also causes masculine rats to be more vocal than their female box mates
Tests on the parts of the brain known to be involved in vocal calls displayed the masculine pups to have up to twice as much Foxp2 protein as the females.
The researchers then ramped up its production in the brains of female pups and diminished it in masculines. This led to the female rats sobbing out more often and their mothers showcasing more interest to them.
The masculines in contrast, became less ‘talkative’, the Journal of Neuroscience reports. Next, the University of Maryland researchers tested samples from ten boys and ladies aged inbetween three and five.
This displayed the women to have thirty per cent more of the Foxp2 protein than the boys, in a brain area key to language in humans.
Researcher Margaret McCarthy said: ‘Based on our observations, we postulate higher levels of Foxp2 in chicks and higher levels of Foxp2 in masculine rats is an indication that Foxp2 protein levels are associated with the more communicative hook-up.’
Studies have shown that the female love of chit-chat embarks at a youthful age. Women learn to speak earlier and more quickly than boys. They produce their very first words and sentences earlier, have larger vocabularies and use a greater multitude of sentence types than boys of the same age.
However, Simon Fisher, one of the Oxford team who very first pinpointed the protein, cautioned against drawing big conclusions from a explore of such a puny number of children.
