In the majority of human beings, the apex of the heart (left ventricle) points towards the left side of the body. Sometimes however (approx. 1/12000 births), a person is born with a condition known as "Dextrocardia", in which the apex of the heart points to the right side of the body instead.
Is there an evolutionary reason as to why the human heart usually points to the left side as opposed to the right side of the body?
(Note: Please don't answer with, "because there is a notch in the left lung", because I will simply reply with, "is there an evolutionary reason for the apex of the heart AND the cardiac notch being on the left as opposed to the right side of the body")
