It's not that easy to find good examples of "naturally muscular" people. I remember to have seen a photo in an old book of a rather muscular Inuit from the early 20th century who could be a good comparison for early humans.
This is wild. Roman glass beads were discovered in Bali, transported 2000 years ago by traders from India. Products from the Roman Empire almost made it to Australia!
Wait, did any pre-agricultural humans understand sexual reproduction? Is it actually self-evident that sex makes babies? Maybe the insight only happened when people started breeding animals and planting seeds. Who was the first person to figure out the birds and the bees?
Many Australian tribes thought babies resulted from reincarnation rather than sex. One tribe described how a tiny spirit would meet a woman, throw a small club at a her big toe and enter her body through the wound. (Mathews, 1900)
@h2ner
Mungo Man who lived in Australia 40 kya also had severe tooth wear. His left molars were worn down almost to the root. Researchers think he processed plant fibers with his teeth in order to make rope or netting
Interpersonal and intertribal conflict was common in Australia. In a study of crania from southeast Australia, 58% of the females and 37% of the males had fractures, the majority of which were severely traumatic. Arm fractures were also common (from parrying blows)
Spot the difference
Australians were once surrounded by Southeast Asian Negritos, Papuans, Melanesians and Tasmanians
Why wasn't their hair the same???
I just passed 600 followers. Welcome, everyone!
Before colonization, there was about 600 tribes in Australia. Most tribes consisted of bands of around 25 people. These bands shared a common tribal language and culture but lacked political unity
Tasmanian & Australian hunters used their toes. A man would drag his spear through the grass to appear unarmed and then flip it into his hand at the last moment. The same technique was also used to kill humans
Most boomerangs were weapons for hunting and fighting. They were meant to deliver the deadliest blow possible and not return

Another reminder that archaeologists have been studying drowned continental shelf sites for 40+ years, unlike some Internet clowns would have you believe.
3. "If you actually count your ancestors, if you're of non-African descent, how many of them were Neanderthals say, 70,000 years ago, it's not going to be 2%. It's going to be 10-20%, which is a lot"

The Australian belief that nobody "just died" had profound implications:
Funerals often involved discerning whose sorcery was "responsible" for the death. Once identified, an avenging party would target the "murderer" or, in some cases, the first person encountered in the

Some researchers believe that brow ridges evolved to shield our eyes from the sun. In addition to projecting brows, people in Australia often had deeply-set eyes
Biological samples are the sole genetic record of the unadmixed Tasmanian people. The remains, often collected by dubious means, are now being repatriated, cremated and buried. No complete DNA analysis has been done and time is running out
There are about 984,000 Indigenous people in Australia (3.8% of the population)
The community is growing rapidly. In the 1970's there was only 100,000 members (1% of the population) but 20 years later the number had tripled to 300,000 (2% of the population) 🧵
People in Australia enjoyed life
They played games, sang, danced and made art. Strong friendships were common. Children were showered with love and kindness and almost never punished
Basedow (1925) said "Happiness seems the essence of their existence" and "Some of the men have
Many Australian tribes also believed Europeans were their dead. A famous case is William Buckley, a runaway convict. The Wathaurong people found him carrying a spear he'd found on a grave, and thought he was the dead man. Buckley lived with them for 32 years

This young woman used her husband's skull as a drinking vessel. The practice of carrying water in human skulls was limited to southeast Australia. (Blandowski, 1862)
Dingoes were sometimes used for hunting and warmth but feral ones were eaten. Desert tribes also raided dingo dens and ate the puppies. Sometimes puppies were spared and raised by the women, especially those with unusual markings. (Tindale, 1974)
Wombats were highly-prized in southeast Australia. To kill one in its burrow, 4 men spent 2-3 days digging multiple shafts, each 15-20 ft deep and 3 ft wide. With only sticks and animal-skin buckets, it was a tiring task that yielded at most 20 pounds of meat. (Blandowski, 1862)
In Australia, cannibalism was both an act of love and an act of hatred. It depends on who you asked. Some tribes ate the flesh of their loved ones. Others tribes only ate the flesh of slain enemies. (Howitt, 1904)
@haravayin_hogh
Great thread. A lot of technological changes happened on the mainland after 8kya and never reached Tasmania. There were probably genetic changes too, which might explain why the wavy hair of southern Australians (L) differs from the wooly hair of Tasmanians (R)
Wow. A recent paper suggests modern humans migrated from Africa ~125kya and then L3 mtDNA carriers went BACK to Africa ~70kya
It'd explain the pre-70ka AMH fossils in Asia and why the M & N lineages in Southeast Asia are older than those nearer Africa
(Cabrera et al. 2018)
In southeast Australia, some tribes wore mummified hands as charms. Often two were used: one hanging on the chest, another on the back. If an enemy approached from behind, the back hand would scratch or pinch the wearer. If the danger was in front, the chest hand scratched
After European colonization, feral cats invaded Australia's deserts, endangering many native species. In response, tribes such as the Pintupi began eating the cats (which they found delicious)
Film by Malcolm Douglas, 1989
I’m not sure. My impression is that some “modern” genes were flowing from Africa and some into it. Also the entire concept of “modern human” is on shaky ground. There doesn’t seem to be an accepted definition, whether cultural, genetic or anatomical
As Weidenreich proposed, a trellis may be the more accurate model
Humans were sharing genes between Eurasia and Africa for hundreds of thousands of years prior to the OOA bottleneck 50-70kya
Adaptive genes spread far and wide, increasing brain size from South Africa to Java
"TWO MEN KILLING WHO HAD KILLED HIS WIFE AND EATED HER (SHE CAN BE SEEN IN HIS STOMACH) AFTER MEN HAD KILLED HIM THEY MADE BIG FIRE TO BURN HIM"

Australian tribes had complex rules on food rights. Here's how a Ngarigo hunter would divide a koala bear:
Self: left ribs
Father: right hind leg
Mother: left hind leg
Elder brother: right forearm
Younger brother: left forearm
Elder sister: backbone
Younger sister: liver
Fore people of the Eastern Highlands, Papua New Guinea. The tribe suffered from a fatal neurological disease called kuru. The condition was caused by prions and transmitted through the mortuary practice of eating the brains of deceased family members
In the Queensland rainforest, people were incredibly short. But in other areas of Australia, such as the northwest, there were reported heights of 6'5" and even 7 feet

Wild news
The multiple Denisovan lineages that admixed with Oceanians are deeply diverged from the original Denisova 3 lineage but this new Denisovan lineage from the SAME cave is even MORE divergent and includes DNA from previously-unknown Neanderthals!
WHAT’S GOING ON???
Interesting story based on conference presentation reporting new 200 ka Denisova genome: “The DNA analysis revealed the male Denisovan had inherited 5% of his genome from an ancient, previously unknown population of Neanderthals.”
Censorship is happening in Australia too for similar reasons
The notorious policeman William Willshire once forced 3 women to travel through a mens-only gap near Alice Springs. The women covered their eyes but were later killed for violating the law

I find amazing that we have photographic evidence of how they were used in a real scenario to work wood. A real window to the past. I always thought it was weird they were used bare handed, but I was wrong.

Excellent analysis of ancient Asian genes. There's strong evidence that Australians and Papuans have DNA from a "deep Papuan ghost" population. Perhaps that's one source of their unique, robust morphology
I'm only an expert in the sense of "obsessively curious guy who is unable to sleep until he figures out what was going on in Australia over the past 50,000 years"
New paper!
Dingoes appeared sometime between 5000-3500 years ago. But who brought them? The connection to Asian dogs fits with either Austronesian farmers or Toalean hunter-gatherers from Sulawesi (my personal favorite)
All that's certain is Australia was never the same

Around 4000 years ago, Australia experienced a major cultural shift. Stone axes, bifacial points, mill-stones, adzes and microliths proliferated (UL, UR). The Dingo appeared (LL) and the Thylacine vanished (LR)
I believe the hunter-gatherer-warriors of ancient Australia would feel humiliated by how they're portrayed today
Attempts to sugarcoat their past is demeaning and stupid. My goal is to learn how they lived, where they came from and what they can teach us about humanity

This zigzag engraving may be the oldest-known work of art. It was found in Java and is ~500,000 years old. Interestingly, the oldest figurative art (a 51,000 year-old painting of people & animals) was recently discovered on the nearby island of Sulawesi
Torres Strait headhunters used bamboo knives during raids on nearby islands and Australia. The razor-sharp blades dulled after each beheading, so they were notched and a new edge formed. Notch count indicated heads taken
Major find: An arm bone from a Homo floresiensis adult who was only 100cm (3' 3") tall. The 700ka bone is from a shorter, more archaic population than the more recent Liang Bua hobbits (who were replaced by sapiens ~50kya). According to the authors, these new finds support the

I admit it feels counterintuitive. The idea seems foundational to our society and sense of identity. But I'd argue that even today the idea isn't fully accepted. Billions of humans still believe that a baby's "spirit" or "soul" is reincarnated or created by a god at conception

Rock art from the northwest coast of Australia (~10,000 years old). Intriguingly, modern tribes still wear similar headdresses on Murray Lake, Papua New Guinea
US soldiers stationed in Papua New Guinea during WWII left behind comic books. One featuring the superhero, The Phantom, captured the imagination of a remote jungle tribe. They integrated the character into their mythology as a demi-god, and now paint him on their shields.
250,000 years would be impressive. Some scientists think humans first arrived in Australia ~130,000 years ago but it's a minority opinion. Also genetics tells us that any people who arrived earlier than ~50,000 years ago were replaced by late waves of migrants
A proclamation board designed by George Frankland, the Surveyor General of Van Diemen's Land (now Tasmania). The goal was to convey the government's commitment to peace and equal treatment under the law. Around 100 copies were made.
In 1829, Frankland wrote to Governor Arthur:
Most Aboriginal Australians have some European ancestry (unlike these two women). Recent photos were used as training data so most AI images reflect this. However, even before European admixture, some people in the central desert did have blond hair (especially as children)

There are almost no depictions of Australian prehistory. Love seeing a new one!
And everything seems probable: fishing, ground ochre, hand-held flakes, simple spears, ornaments, lack of clothes. I suspect their hair was curlier (like Tasmanians) but it's as good a guess as any
