It is shown that the energy required in order to articulate manual and oral gestures at a given rate varies in proportion with the fifth power of linear body size, while the energy supply varies with its second power. This provides for a better understanding of the differences in peripheralness observed in the formant frequencies of vowels in speech articulated more or less forcefully by men, w...

Over time, the genetic and molecular attributes of these patterni...
