The left hemisphere of the human brain is

largely responsible for language. Men are more likely

to suffer speech disorders if the left side of

their brain is damaged, women if the front part of

their brain is damaged.

Men are better at solving maths problems, but women are better with straight arithmetic. Women

are better at tests involving words and manual

dexterity. Men are better at rotating objects in space.

Professional musicians have left hemispheres

that are better developed in terms of processing sounds, compared to those of non-musicians.

The brain of our early ancestors, who lived

50,000 or even 400,000 years ago, are not noticeably different in terms of size or outward complexity.
