A right-hander finds it easier to draw faces of people and animals facing towards the left wherea s a left-hander finds it easier to draw faces towards the right. Both kind of face have been found in ancient painting.On the whole , the evidence seems to indicate that prehistoric people were either ambidextrous or about equally likely to be left or right handed.
