Today's Daily Mail runs a story which tells how recent studies prove what we already suspected: younger sons are more rebellious than their conservative older brothers.

The newspaper uses Second Testament Bible story The Prodigal Son to illustrate the point.  But there are more biblical exceptions to this rule, than examples that prove it: Jacob and Esau, Cain and Abel, Joseph and all his older brothers. 

Which other younger brothers are actually the heroes of the story and are there any more examples in the bible that prove the rule?
