Before bows and arrows, hunters used spear throwers called atlatals


 

 

 

 

 

 

 

 

 

 

There is a 2025 book by Sam Kean titled Dinner with King Tut: How rogue archeologists are re-creating the sights, sounds, smells, and tastes of lost civilizations. I blogged about it in a post on January 26, 2026 titled What did Egyptian laborers who built the pyramids eat? That book has eleven chapters that cover the following dates:

 

Africa – 75,000 years ago

South America – 7500 BC

Turkey -6500s BC

Egypt – 2000s BC

Polynesia – 1000s BC

Rome – AD 100s

California – AD 500s

Viking Europe – AD 900s

Northern Alaska – AD 1000s

China – AD 1200s

Mexico – AD 1500s

 

Chapter 2, South America – 7500 BC, has a section starting on page 67 about a spear thrower (shown above) called an atlatal:

 

“The atlatl is a two-foot-long stick with a hook or spur on one side. The darts are wooden shafts with a stone point hafted to one end and a concave cup carved into the other. (Asana prefers shorter darts, a yard or so long, since they can double as spears in a pinch). To load an atlatl, you hold it at shoulder-height, parallel to the ground, and fit the cup end of the dart into the spur-hook. To fire the dart, you step forward and snap the atlatl down with your wrist. Imagine flicking paint off a paint-brush – same motion. Overall, your thigh and core generate the power, which gets channeled into the dart via the arm and snapped wrist.

 

To the uninitiated, the atlatl probably seems baroque. Why not just hurl a spear, instead of using a stick to fling it? A detailed answer would require a long digression into the physics of levers and rotational velocity, but the basic idea is this: the longer your arm, the faster you can throw something. (Think of those long plastic ball-throwers for playing with dogs.) Atlatals effectively lengthen your arm by a foot or two and therefore provide a huge speed boost: experts can fling the darts 80 mph, while spears alone top out around 50 mph. Speed is a major factor in a weapon’s penetration ability and knockdown power, so atlatl darts are pretty darn deadly.

 

Despite their obscurity nowadays, especially compared to spears or arrows, atlatls were probably the most widely used hunting weapon in prehistory, in climates from the tropics to the poles. As a result, there’s a serious contingent of atlatl enthusiasts within experimental archaeology.

 

I get to try atlatls myself during an undergraduate class that Mein Eren teaches. We meet at a frisbee golf course near campus, where he unloads several dozen atlatl darts from his pickup. Each is around six feet long and a bit less than an inch thick, and they’re fletched with fake feathers – neon, green, black-and-blue, crimson. I’m surprised how bendy they are, quite flexible. Atlatlists debate why that flexibility matters, but rigid darts simply don’t fly as straight or true: darts need spring.

 

The atlatls Eren hands out are pretty basic – wooden sticks with hooks. Most people throughout history used something similar, but the inhabitants of the treeless altiplano would have saved their wood for darts and made atlatals from the leg bones of vicunas. (I actually stumbled across one such bone on a walk in Peru. It was bleached white, and differed from traditional atlatls in that it had a kink in it. But when I whipped it downward with my wrist, it felt perfect.)”

 

And Chapter 7, California – AD 500s. has another topic starting on page 270:

 


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

“Bows and arrows were the single most complicated piece of technology in prehistoric times, incorporating nearly every material used by our ancestors – wood, stone, sinew, antler, resin, rope, feathers. And while atlatals long predated them, bows and arrows eventually replaced atlatals on nearly every continent. There are several reasons why.

 

The big advantage of atlatals is that their heavy darts pack quite a punch; you can really wallop game. But as megafauna went extinct on continent after continent, the importance of landing a big blow waned in tandem. Hunting smaller game requires stealth and precision, and bows and arrows allow you to hide in a blind and snipe at game instead of scaring them off with the big clumsy movement of an atlatl toss. You also stand still while shooting them, and can sight down an arrow and take aim, something that’s impossible with the side-armed atlatl. Arrows offer a superior rate of fire, too. With atlatals, you usually get one throw before an animal flees, but it’s possible to fire several arrows in quick succession. (Some Plains Indians could keep eight in the air at once). All in all, after the decline of the megafauna, arrows proved more superior in most hunting scenarios.

 

But as with all technological advances, the switch to bows and arrows was accompanied by social upheaval. For one thing, bows and arrows seemingly favored individuals over groups. When everyone used big, slow atlatals and got just one shot at game, hunting in groups was necessary to hedge bets. In contrast, the precision and stealth of bows and arrows encouraged solitary hunting. The group became less important.

 

Arrows might also have upended the relations between the sexes. Recall from Chapter 2 that women often throw atlatals better than men. Bows and arrows, however, tend to favor males. That’s partly because men are generally taller and generally have more upper body strength, bothof which provide an advantage when shooting bows. (Arm length and arm strength allow an archer to use a stiffer bow and pull the string back farther, generating more snap). That said, it wasn’t all biology; cultural factors favored males as well. However clumsy atlatals seem at first, people could master them reasonably quickly; children as young as seven can take down deer with them. Proficiency with arrows takes more practice; few children can reliably kill game with arrows until their mid-teens. And for whatever reason, most cultures in the ancient world – in Africa, in Asia, in Europe, in the Americas – denied young females the chance to develop this skill, shunting them off to gather plant food instead. As a result, bows and arrows became a male-dominated weapon.”

What did Egyptian laborers who built the pyramids eat?


 

 

 

 

 

 

 

 

 

 

 

 

There is a 2025 book by Sam Kean titled Dinner with King Tut: How rogue archeologists are re-creating the sights, sounds, smells, and tastes of lost civilizations. It has eleven chapters that discuss the following dates:

 

Africa – 75,000 years ago

South America – 7500 BC

Turkey -6500s BC

Egypt – 2000s BC

Polynesia – 1000s BC

Rome – AD 100s

California – AD 500s

Viking Europe – AD 900s

Northern Alaska – AD 1000s

China – AD 1200s

Mexico – AD 1500s

 

There is also an article by Sam Kean in Nautil Us on July 9, 2025 titled How to Make the Bread That Fueled the Pyramids. Similarly, beginning on page 128 of the book he says about Egypt in the 2000s BC:

 

“From the most wretched servant to the most exalted prince, people in ancient Egypt ate bread and drank beer with every meal. These staples were so vital to their diet that, in Egyptian hieroglyphs, the combined symbols for bread and beer actually meant meal or sustenance.

 

During pyramid construction, bakeries the size of football fields stood near the worker villages. Every morning, battalions of men and women would grind up bushels of emmer – the main grain eaten in Egypt – into flour on stone hand mills called querns. Still more bakers mixed and kneaded the dough, probably with their feet. To bake the bread, rather than waste time making thousands of mud ovens, crews used conical clay molds. They’d dig holes in the ground, fill them with glowing embers, drop the molds in upside-down, plop some dough in, then cap each mold with a second one and heap hot ash over the top. The endless rows of these devices made the lot behind the baking huts look like giant egg cartons.

 

Timing was critical. The glowing embers had to be ready the same time as the dough was, and the bread had to finish just as the construction crews and other laborers were lining up for meals. Given the immense scale, there was a factory feel to the operation, and someone like Amon was as much a foreman as a baker, equally concerned with workflow and worker training as he was flour quality or seasoning.

 

….Blackley shows me his replica mold. It’s scorched black and much heftier than I expect – fifteen inches across and probably twenty pounds.

 

As a treat, Blackley has also baked a loaf for me to sample. It’s a foot wide and sand colored with a springy crust. It consists of just a handful of ingredients – salt, yeast, coriander, emmer flour – and its blunted shape reminds me of NASA space capsules [like the Apollo] from the 1960s.  

 

….Beyond bread, Egyptian laborers were paid in beer as well – 1 1/3 gallons daily, roughly ten pints, which they happily sucked down given that temperatures on the hot sands could reach 130oF. (One scholar estimated that it took 231 million gallons of beer to build the largest pyramid). Even children drank beer, largely because the alcohol killed microbes and rendered it more sanitary than the water in rivers (a.k.a. their sewers). Egyptian doctors also prescribed beer as medicine to remedy coughs, constipation, swollen eyes, and upset stomachs.”

Superficial research in an article about fear of mass shootings


 

 

 

 

 

 

 

 

 

 

 

 

 

There is an article with superficial research by James Alan Fox at USA Today on January 14, 2026 titled There’s no mass shooting epidemic, but fear epidemic is real | Opinion. He says (as shown above) that:

 

“Although the frequent claims of a ‘mass shooting epidemic’ are more hyperbole than reality, there truly is an epidemic of fear fueled by the extensive media coverage afforded deadly attacks in schools, churches, restaurants and other public settings.

 

Indeed, the percentage of Americans indicating that public mass shootings are a significant source of worry has nearly tripled, from 16% in 2015 to 44% in 2025, based on the Chapman University Survey of American Fears." 

 

The first data point for fear of a random or mass shooting really should be from 2014 rather than 2015, and be 24.7% - which is 51 percent larger than the 16.4% that Prof. Fox uses. So his comparison would just be an increase of 79% rather than a near tripling.

 

 




  

 

 

And those are only two of eleven data points in those Chapman surveys, as is shown above. When you only use ~18% of the available data, you will get a grossly misleading picture of what really is going on.

 

There also is another article by James Alan Fox in the Journal of Contemporary Criminal Justice for July 31, 2023 (Volume 40, number 1) titled Trends in U. S. Mass Shootings: Facts, Fears, and Fatalities. Figure 2 in it is a vertical bar chart showing seven Chapman Survey data points from 2015 to 2022, but it also omits the 2014 data point and instead of listing 47.4% for 2019 (the very highest point!) it repeats the 41.5% from 2018. Also, he reports 28.1% for 2017 when the correct number in the detailed results instead is 30.8%. I discussed this problem in a blog post on October 4, 2017 titled What do the most Americans fear? The fourth Chapman Survey on American Fears, and being innumerate.

 

 

 


 

 

 

 

 

 

 

 

 

Is fear of a random or mass shooting the greatest fear in the Chapman surveys? No – corrupt government officials are. As shown above in a bar chart, fear of a random or mass shooting ranked from a low of #56 to a high of #22.

A free Reference Guide to American English Idioms


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Idioms are important in speechwriting. The Merriam-Webster Dictionary defines an idiom as carrying a figurative or non-literal meaning:

 

“an expression in the usage of a language that has a meaning that cannot be understood from the combined meanings of its elements (such as up in the air for ‘undecided’) or in its grammatically atypical use of words (such as give way for ‘retreat’).”

 

Having a dictionary or reference guide for idioms is very useful. There is a free 133 page pdf e-book by the Office of English Language Programs at the United States Department of State from 2010 titled IN THE LOOP: A Reference Guide to American English Idioms. You can download it either here or here.

Steeped in an excellent metaphor


 

 

 

 

 

 

 

 

 

 

 

 

 

There is a very serious, 9-page pdf article by Pragnesh Parmar and Gunvanti Rathod at Academic Forensic Pathology on January 13, 2026 titled The Tea-Steeping Metaphor: Origin, Application, Advantages, Disadvantages, and Impact on Forensic Medicine Teaching. I found it by searching PubMed Central. The article describes how:

 

“The ‘tea-steeping metaphor’ originates from a universally familiar process—brewing tea—where the infusion of flavor, color, and aroma is directly influenced by the duration of steeping and the conditions in which it occurs. This analogy has been increasingly embraced in educational literature to illustrate the pedagogical necessity of allowing learners adequate time and appropriate contexts to achieve deep, meaningful learning. The metaphor emphasizes that just as tea leaves gradually infuse water to create a robust brew, learners too require sustained engagement within conducive environments to fully internalize, reflect upon, and apply new knowledge.”

 

Four paragraphs describe advantages, which are:

Encourages Deep Learning

Supports Patience and Persistence

Promotes Reflective Practice

High Adaptability Across Contexts

 

And another three paragraphs describe disadvantages, which are:

Time-Intensive Nature

Risk of Over-Saturation

Dependence on Optimal Learning Conditions

 

On April 19, 2022 I blogged about How to do a better job of researching medical and health articles. In that post I mentioned PubMed Central, which is a database with 11.6 million articles compiled by the U. S.  National Library of Medicine.

Life in the Present is a wonderfully joyful little book of comics by Liz Climo


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

There is a 112-page book from 2024 by Liz Climo titled Life in the Present: a joyful collection of comics about living in the moment. As shown above (in my version), the cover has a hamster looking out from a window in a gift box. That comic is shown on page 84. Its first frame has the hamster reading a book and is captioned:

 

“True happiness comes when you live in the present.”

 

Four sections in it are titled:

 

Work (page 7)

Play (page 32)

Rest (page 60)

Reflect (page 85)

 

There is a post by Rafael Velez at the threadless blog on July 19, 2024 titled Liz Climo on Living in the Present: Comics, Joy, and Everyday Magic.

 

And three examples of dialogue in this book from her cartoons are:

 

Page 34

Bear (playing cards): I get so nervous making new friends. What if they’re grumpy? Or have nothing to say? What if they get on my nerves?

Rabbit (also playing cards): Do you ever wonder if anyone feels that way about you?

Bear (still playing cards): Oh, no, I’m a delight.

 

Page 58

Penguin: Let’s hang out sometime. What’s your number?

Turtle: 6.

Penguin: Just 6?

Turtle: Yeah, I’m really old.

 

Page 89

Weasel (reading text from shark): Everyone is scared of me, do you think it’s because I’m so brutally honest?

Weasel (replies): Nah, dude, it’s because you’re a shark.

 

Many other cartoon are shown in a series of seven collections over at boredpanda:

According to eight Chapman Surveys of American Fears, more adults fear sharks than fear public speaking – but neither is their top fear.


 

 

 

 

 

 

 

 

 

 

 

 

Way back on October 27, 2009 I blogged about an often-quoted old survey (where public speaking was the top fear) in a post titled The 14 Worst Human Fears in the 1977 Book of Lists: where did this data really come from? In that post I noted:

 

“The movie Jaws came out in 1975, so by next year I suspect that sharks were ‘top of mind’ and would have made any list of top ten fears.”

 


 

 

 

 

 

 

 

 

 

 

Finally, starting in 2017, the annual Chapman Survey of American Fears asked about Sharks. As shown above for eight surveys, more people fear them than fear Public Speaking.

 


 

 

 

 

 

 

 

 

 

 

But, as also is shown above, Corrupt Government Officials were the top fear in ten surveys, and Public Speaking only ranked from #26 to #59.
