Every human being, has traits which he does not get from his society.
Australian elders can teach a boy to throw a boomerang, but they can not permanently alter his chocolate skin by smearing paint on it.
Skin color and other physical traits are inherited not socially but by biological hereditary.
An Australian child brought up by a white rancher tends sheep instead of throwing boomerangs at kangaroos; he may learn to write, as do white children, and to drive an automobile.
But no matter how much he associates with whites the color of his skin, the shape of his skull and the width of his nose remains unaffected because they can come to him only from his parents.
Thus, every human being has a social and a racial (biological) inheritance.
The two may be in some measure related, but they are different.
