Are the differences between men and women biological or social?

It is often said that men and women are totally different. I remembered that even there was a book called 'Men are from Mars, and women are from Venus'. They have different characteristics and abilities. However, the question is that whether the differences come from biological or social causes. In my opinion, both biological and social reasons make the differences between men and women.

First of all, we can see that men and women are biologically different. Not only do they have a different body and appearance, but also feelings and characteristics. Genarally, for example, women are more sensitive than men. They consider one's feeling as the most essential thing in realitionship with people. To take another example, men tend to concentrate on one work, while women are able to do various jobs at the same time. We can see that these examples are more related to biological factors rather than social factors. What I mean is that these differences are not an ability or a habit which can be acquired by experience.

However, social situations also make the differences between the both sexes. It is true that people have such a stereotype of gender. For instance, 'Boys should play with a toy car, but girls should play with a doll' or 'Men should be tough, while women should be elegant'. In other words, they emphasize manhood and womanhood. For this reason, people educated their sons and daughters in different ways, and this leads to the difference between men and women.

To conclude, the reason for the differences between men and women is both biological and social. However, I would like to say that the important thing is not distinguishing charateristics between both sexes, but understanding each other.
