Sibling rivalry stems back to ancient biblical times with the story of Cain and Abel—two brothers in competition with each other for their father’s approval. Their story is rife with emotion, love, hate, and jealousy. It ultimately ends with pain and tragedy. The story of Cain and Abel highlights some of the unique aspects that set sibling relationships apart from all others. It’s a bond forged by both biology and circumstance.
