No one here is taking science seriously! :)
This could have major implications...for what I have no idea.
All it could mean is that the boffins (buffoons?) messed up the mouses vocal controls...one would think that the scientists have to explain the genetic encoding of speaking tissue, nerve control, cognitive functions, neologisms,and other features of speech...
Read the late Tom Wolfe’s last book, KINGDOM OF SPEECH for an interesting foray into linguistic research.
