Yet Again, We Got It Wrong

Mothers have a tendency to be altruistic in regards with their offspring, with all of them. This is explained in Chapter 8 of The Selfish Gene, called the Battle of the Generations. But it also explains that, again because of our competitiveness, siblings will always be looking to be the favorite, the one with the most attention and affection. Therefore, it is normal that jealousy should arise. Perhaps the most famous story about brotherly jealousy is the one that precisely condemns it. Cain and Abel appear in the Old Testament as two brothers, one a shepherd and one a farmer. They were giving their offerings to God, Abel with his sheep and Cain with his fruit, and God seemed to prefer Abel´s gift over Cain´s. Jealous over the Father´s preference, he smashed Abel´s head until he was dead, and later denied it to God. He was heavily punished by his father, condemned to eternal wandering. But the importance of this story in Genesis is unbelievable. Almost the complete cause, it lead to the frowning upon anyone who does not have a healthy relationship with their sibling(s). But competition between us is, in fact, natural. Our animal instincts are again frowned upon by our strict society, proving even more that etiquette and social correctness are simple conventions invented to make our lives more complicated. So, once again, we got it wrong.
