# Coalitionary Killing Has an Evolutionary History by Richard Wrangham > “However, current evidence supports the hypothesis that selection has favored a hunt-and-kill propensity in chimpanzees and humans, and that coalitional killing has a long history in the evolution of both species.” > **— Richard Wrangham**, *“Evolution of coalitionary killing,” 1999* ## Sources and Context - **Authored research abstract:** [Wrangham, “Evolution of coalitionary killing,” American Journal of Physical Anthropology, Supplement 29 (1999)](https://pubmed.ncbi.nlm.nih.gov/10601982/). This is his stated hypothesis and evaluation of evidence, not a settled universal explanation. The abstract specifies intergroup hostility and a sufficient power imbalance as proposed conditions and calls for further testing. ## Related Articles and Collections - **Collection:** [[collections/Machine Succession|Machine Succession]] - **Collection:** [[collections/Simple Reminders|Simple Reminders]] - **Article:** [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] - **Article:** [[articles/Walking the Beautiful Path Through the Greatest Transformation in Human History|Walking the Beautiful Path Through the Greatest Transformation in Human History]] - **Wiki map:** [[wiki/Coalitionary Aggression|Coalitionary Aggression]] ## Related Topics - [[wiki/Richard Wrangham|Richard Wrangham]] - [[wiki/Coalitionary Aggression|Coalitionary Aggression]] ## Share on Social Media ``` “However, current evidence supports the hypothesis that selection has favored a hunt-and-kill propensity in chimpanzees and humans, and that coalitional killing has a long history in the evolution of both species.” — Richard Wrangham, Evolution of coalitionary killing, 1999 https://bryantmcgill.com/simple-reminders-richard-wrangham-coalitionary-history ```
