According to Brinkman, as the brain evolved, one side became specialised for fine control of movement (necessary for producing speech) and along with this evolution came righthand preference.

根据Brinkman，认的大脑发展，一面变得专门很好的控制行(产生语言能力的需要)并且沿着这种发展成惯用右手偏好。

Dr Brinkman, a brain researcher at the Australian National University in Canberra, has suggested that evolution of speech went with right-handed preference.
