Lloyd Warner's book 'A Black Civilization' is a comprehensive ethnography of the Murngin (Yolngu) people of northern Australia. Published in 1937, it's one of the v few detailed accounts of Aboriginal warfare amongst other topics. A thread:
He opens with a stark declaration that the Murngin couldn't exist without warfare, that it is essential to the structure of their society.
One of the primary reasons for this is the polygynous basis of sex relations. Each married man has an average of three and a half wives, leaving a reservoir of unattached young men. These guys are the fodder for social violence and are the primary victims and aggressors.
This brutal imbalance is often theorised to be a evolutionary mechanism behind sex relations, but it's rare to see it so clearly demonstrated.
"warfare, then, is one of the mechanisms on which polygyny is based"
Causes of warfare are pinned down to four major reasons - blood revenge, theft of a woman, black magic and improperly gazing upon the clan totem.
"the idea underlying most Murngin warfare is that the same injury should be inflicted upon the enemy group that one's own group has suffered"
A socially accepted form of death was for women who spied upon sacred male rituals or who polluted the production of emblems and totemic objects with their presence. Noone objected to such offences being punished lethally, even across clan lines.
The six kinds of Murngin warfare - a camp fight, secret murder, night raid, open fight, pitched battle and ceremonial fight. Also a kind of 'women's combat' which apparently isn't one of the main six.
The arms and weapons of the Murngin.
The camp fight or Nirimaoi, usually a result of adultery or cuckolding. Sounds like a classic bar scrap, lots of bravado and posturing and rarely ends in death.
The secret murder, the 'Narrup', is usually a surprise attack on a sleeping person. Despite one person doing the slaying, the whole clan is held responsible and an older man assumed to be the 'pusher' or agitator.
The 'Maringo' or 'death adder' night raid is a lethal extra-clan attack, intended to avenge a death. A ritual procedure involving the dead man's relics is performed at camp before the men use a 'snake' formation to attack their enemy.
The 'Milwerangel' or general fight has no great ceremonial basis, but rather a quick skirmish.
The 'Gaingar' is a more serious and organised form of pitched battle. These occur after a hysteria of emotion has been reached after tit for tat killings and a resolution is needed to prevent further deaths.
Finally, the 'Makarata', or ceremonial peace making fight is a blend of highly controlled ritual, dance and machismo, but directed towards placating emotions with minimal bloodshed.

*Haiti Update April 2025* - the international Kenyan led forces have failed to dislodge the gangs now running the capital, cholera outbreaks have been noted, gang rape is rife and the homicide rate continues to increase.
Rival gangs are looking to spread outside of Port-au-Prince, targeting prisons, roads and buses for kidnapping operations. There's something surreal about the fact that a gang faction called 'Taliban' has a stronghold in a suburb of Port-au-Prince called Canaan.
Politically Haiti is currently ruled by an unelected council, since it has been unable to commence elections and there are no legitimate politicians left to rule. The hope is that new elections will be run in Nov 2025, but the gangs are seeking to destabilise this situation.
Around AD 1500 this six month old child was buried under a pile of flat stones and sealskins, in the shadow of a large cliff at Qilakitsoq, Greenland. Centuries later experts determined he was likely buried alive, on the body of his mother 🧵
Qilakitsoq is in eastern Greenland, and was occupied by the Thule Inuit, who arrived circa AD 1250. They pushed out the original Dorset Culture people, and named the site Qilakitsoq, meaning 'that which has little sky', a reference to the high cliffs.
In 1972 a pair of brothers out grouse hunting stumbled upon a burial site in the cliffs.
Somewhere between 500-800 million people rely on cassava root as their main source of carbohydrate. Incredibly it looks like many of them suffer from chronic cyanide poisoning as a result of improper preparation
The quantity of cyanide depends on the cultivar, growing conditions and differences between the root and leaves of the tuber. The amount ranges from 15-1000mg cyanide per kilo of root.
Turning raw cassava root into a safe and edible food requires careful processing to reduce the cyanogenic glycosides. A combination of crushing/fermenting, plus drying seems best - some simple methods like boiling do very little to detoxify the root.
A thread on the Pacific Dwarf mythology that accompanied the Austronesian expansion - the Primordial Little People Type-Tale
The dominant hypothesis as to why many Austronesian-Polynesian cultures have a foundational little-people story, is that when the proto-Austronesians arrived in Taiwan they found a short statured Palaeolithic people already living there.
This theory was recently strengthened by the discovery of 'negrito-like' human remains in Taiwan, dating back around 6000 years. The skull shows many similarities to other Negrito and African San peoples.
In 2016 the British Dental Journal identified a new child protection issue - the sub Saharan practice of gouging out the healthy tooth buds of children, euphemistically called 'Infant Oral Mutilation' (IOM) 🧵
IOM is the practice of removing erupting infant teeth in order to prevent ill physical and spiritual health - the buds are believed to be tooth worms or bad spirits which cause diarrhea and fevers. The cure is to remove the primary teeth.
The teeth are extracted in an extremely crude and painful manner, using bike spokes, penknives, hot nails, fingernails, razor blades etc, without anaesthetic and with the high risk of blood loss and subsequent infection, including passing on HIV or hepatitis B.

The British authors survey both the European and Aboriginal inhabitants, considering the former to be a "sub-type of the British race... far more assertive, self-confident, ruthless"
"The Sturdy Stock They Raise On Australian Farms" - the authors mention the low birth rate in the cities, but praise the outdoor Australian lifestyle, as well as pointing to new technologies replacing older rural livelihoods.
