Different Features of human being of different regions (East, West, North and South)
Usually the people in the western region and northern region of the world are almost same they have the following features: white in color, big, tall etc.
Those living in the southern part of world are known as Negros, they are very black in color, with curly hair.
The people in eastern region of the world are not tall unlike those in the western region, are neither white like western people nor black like the Negros.
In these ways they are different from each other, moreover they have different food items, they speak different language
Types of languages
