Defying the old adage promoted in 1992 bestseller 'Men are from Mars, Women are from Venus', a new book has claimed that the two genders are actually from the same planet.
The difference between men and women is down to the way they were brough up, claim scientists
In fact it is nurture, rather than nature, that has the largest effect on skills, attributes and personalities.
Thus, boys aren't born with better map reading and parking skills and girls don't come into the world able to multi-task and communicate better.
Instead, we are steered towards gender-defined skills by parents and teachers.
According to the book, titled 'Delusions of Gender', by Cordelia Fine, a Melbourne University psychologist, there are no major neurological differences.
There may be slight variations in the brains of women and men but the wiring is soft, not hard.
And Dr Lise Eliot, of Chicago Medical School, agrees.
"Children don't inherit intellectual differences. They learn them. They are a result of what we expect a boy or a girl to be," the Daily Mail quoted him as saying.
"Yes, boys and girls, men and women, are different. But most of those differences are far smaller than the Men are from Mars, Women are from Venus stereotypes suggest," Eliot told the New Scientist.
