They predicted a greater proportion of siblicides of in-law siblings will be perpetrated by beatings, relative to the proportion of siblicides of full siblings. This difference did not reach statistical significance although it was in the predicted direction. They found, as predicted, that a significantly greater proportion of… 
The Evolutionary Psychology of Sibling Conflict and Siblicide
Conflict between siblings is common, not only in humans, but also in a wide variety of other species. It is also an unsurprising phenomenon, as offspring compete for dominance as well as food
Evolutionary Perspectives on the Nature of Sibling Conflict: the Impact of Sex, Relatedness, and Co-residence
Our siblings can be our closest allies and yet are often our first rivals. What factors influence the nature of these relationships, and are there certain aspects that make our siblings more likely
Genetic Relatedness, Emotional Closeness and Physical Aggression: A Comparison of Full and Half Sibling Experiences
TLDR
No effect of genetic relatedness was found in Study 1 when participants’ ratings of emotional closeness were compared; participants also reported significantly higher levels of conflict with full siblings than with half siblings; and findings were contrary to the prediction from Hamilton’s rule.
