It's an age-old dispute: Men are from Mars. Women are from Venus. Males and females show different behaviors almost from birth. Researchers say these behaviors are due to basic differences in brain structure and activity. Studies show men are better at hitting targets and solving math problems while women are better at memorizing words and recognizing faces. Why the difference?

这是一个自古就存在的争论：男人来自火星，女人来自金星。男人和女人几乎自出生起就有不同的行为。研究人员表示，这些行为是由大脑结构和大脑活动的基本差异所引起的。研究显示男人较擅长于射中标靶和解决数学问题，而女人则比较擅长记忆文字和辨识脸孔。为什么会有这种差异呢？
