Sister

A sister is the female offspring of one's parent.

Overview

The term sister comes from Old Norse systir which itself derives from Proto-Germanic *swestēr, both of whom have the same meaning, i.e. sister. Some studies have found that sisters display more traits indicating jealousy around their siblings than their male counterparts, brothers. In some cultures, sisters are afforded a role of being under the protection by male siblings, especially older brothers from issues ranging from bullies or sexual advances by womanizers.

Studies

Various studies have shown that an older sister is likely to give a varied gender role to their younger siblings as well as being more likely to develop a close bond with their younger siblings. Older sisters are more likely to play with their younger siblings. Younger siblings display a more needy behavior when in close proximity to their older sister and are more likely to be tolerant of an older sisters bad behavior. Boys with only an older sister are more likely to display stereotypically male behavior, and such masculine boys increased their masculine behavior with the more sisters they have. The reverse is true for young boys with several sisters, as they tend to be feminine, however they outgrow this by the time they approach pubescence. Boys with older sisters were less likely to be delinquent or have Emotional and behavioral disorders. A younger sister is less likely to be scolded by older siblings than a younger brother. The most common recreational activity between older brother/younger sister pairs was art drawing. Some studies also found a correlation between having an older sister and constructive discussions about safe sexual practises.

Cain and Abel

Cain and Abel (Hebrew: הֶבֶל ,קַיִן Qayin, Heḇel; Arabic: قابيل، هابيل‎ Qabeel, Habeel) were, according to the Book of Genesis, two sons of Adam and Eve. Cain is described as a crop farmer and his younger brother Abel as a shepherd. Cain was the first human born and Abel was the first human to die. Cain committed the first murder by killing Abel. Interpretations of Genesis 4 by ancient and modern commentators have typically assumed that the motives were jealousy and anger. The story of Cain and Abel is found in the Christian Bible, Jewish Torah and Muslim Quran.

Genesis narrative

Hebrew Bible version:

²Then she also gave birth to his brother Abel. Now Abel became a shepherd of a flock, but Cain cultivated the land. ³In the course of time Cain presented some of the land's produce as an offering to the Lord. ⁴And Abel also presented [an offering] – some of the firstborn of his flock and their fat portions. The Lord had regard for Abel and his offering, ⁵but He did not have regard for Cain and his offering. Cain was furious, and he was downcast.
