Amazonian tribal warfare sheds light on modern violence, anthropologist says

3

In the tribal societies of the Amazon forest, violent conflict accounted for 30 percent of all deaths before contact with Europeans, according to a recent study by University of Missouri anthropologist Robert Walker. Understanding the reasons behind those altercations in the Amazon sheds light on the instinctual motivations that continue to drive human groups to violence, as well as the ways culture influences the intensity and frequency of violence.


“The same reasons – revenge, honor, territory and jealousy over women – that fueled deadly conflicts in the Amazon continue to drive violence in today’s world,” said Walker, lead author and assistant professor of anthropology in MU’s College of Arts and Science. “Humans’ evolutionary history of violent conflict among rival groups goes back to our primate ancestors. It takes a great deal of social training and institutional control to resist our instincts and solve disputes with words instead of weapons. Fortunately, people have developed ways to channel those instincts away from actual deadly conflict. For example, sports and video games often involve the same impulses to defeat a rival group.”

Walker examined records of 1,145 violent deaths in 44 societies in the Amazon River basin of South America by reviewing 11 previous anthropological studies. He analyzed the deaths on a case-by-case basis to determine what cultural factors influenced the body counts. Internal raids among tribes with similar languages and cultures were found to be more frequent, but with fewer fatalities, when compared to the less frequent, but deadlier, external raids on tribes of different language groups.

  1. Yes, humans do not need to learn violence, but some humans seem to have a hard time learning peace. 

    Religion is no small instigator of this lack of learning as it can be a rationalization for all the other instigators, including  jealousy over women.

  2. The article ends with the conclusion :

    “The spread of Christianity and the imposition of legal structures..reduced the deadly raids.”

    We don’t know which of the two had the greatest impact. Two variables lumped together. Pity!

    The article ends with the conclusion :

    It would be interesting to know to what extent this includes killing by outsiders.

    The issue of  “imposition of legal structures”, (and illegal structures) by force and indifferent or corrupt governments, is well known in dispossessing native tribes of their land and rights.

    Yasuni – The Most Biodiverse Forest on Earth

    Yasuni Rainforest Campaign works with the Waorani people, scientists, non-profit environmental and human rights groups in Ecuador, the U.S. and around the world, and lawyers, in order to protect the biodiversity of Yasuní and the rights and culture of the indigneous people who live there.

    We have scored major victories against the oil companies, and are leading the fight to turn the tide of history for ecologically sustainable future for this region and its people. Working with the world’s leading scientists, including Jane Goodall and E.O. Wilson, local and international NGO’s and the native Waorani, Save America’s Forests stopped the giant Brazilian oil company Petrobras from building an oil
    road into Yasuní.

    Working in 2006 with the Waorani, we also got the Ecuadorian government to draw the boundary of the “no extraction zone” (Zona Intangible) to include major oil deposits in the southern portion of Yasuní.

    This prevents these oil deposits from being developed, and will protect the forest and the indigenous people in this area of Yasuní.
    Now we are working to stop illegal logging and new oil projects by Petrobras, Sinopec, Andes Petroleum, and other threats to Yasuni and the Waorani.
