Evidence.
Not that I’m trying to overturn a paradigm. I’m just pointing to the absurdity of imagining that Australopithecus didn’t use weapons as part of their toolkit for wandering widely over the Earth. Dart twigged that from examining the Taung Child skull 99 years ago.
Yes, Dart thought his hominins used faunal remains as weapons. The trouble was, he couldn’t show any evidence for it.
The_Metatron wrote:Dart pointed to the use of humeri as clubs and horns as daggers (Dart & Craig 1959), rather than suggest as Oakley (1949) had that hominins may have manufactured tools from organic materials such as wood, which would not have survived in the archaeological record. Dart wanted direct material evidence to support his claim that A. afarensis was a hominin, and he provided this by claiming that shared with H. sapiens a predilection for flesh eating, hunting, and violence (Fig. 2.3) (Domínguez-Rodrigo 2002).
Ironically, it was an inability to verify that these faunal bones were used as tools that brought so much criticism from colleagues. Although infamous for his proposals of an early ‘Osteodontokeratic culture’, this idea had at least one precedent, put forward by Abbé Breuil at a conference in 1936. Describing a purported bone tool industry from the much later site of Zhoukoudien, Breuil had suggested that humans were ...surrounded by animals better armed by Nature than himself...What more natural than to rob them of these weapons to use against them? Ever a hunter, Man had around him the skeletal remains of his victims...Some of the completed longer bones made excellent clubs with handles not easily broken. (cited in Binford 1981, p.11)
Dart was aware of Breuil’s claims of a material culture involving bone weapons at Zhoukoudien, as well as Breuil’s claims of bone tool cultures at Cave of Hearths in South Africa (Dart & Craig 1959). Dart’s ideas were once again questioned by established academics, including Sherwood Washburn in Australopithecus: The Hunters or the Hunted? (Washburn 1957) on the basis of similar patterns at carnivore sites, with Dart’s theory ultimately disproven by C.K. Brain in his study of cave taphonomy (Brain 1980). Milks et al., 2018, pp. 43-44
… many of the observations made by Dart, such as the striking disproportions of skeletal parts in the fossil assemblage, had explanations different from those that Dart had proposed. For instance, my work (Brain 1981) showed that the disproportions were linked to the varied robusticity of skeletal parts: some bones are simply better able to survive destructive treatment than others. In fact, it is possible to predict which parts of a skeleton will survive any given destructive process and which will disappear. It is no longer necessary to invoke deliberate hominid selection of bones to account for disproportions in a fossil assemblage. Similarly, subsequent work on hyaenas (Maguire et al. 1980; Skinner et al. 1980), particularly the striped hyaena, Hyaena hyaena whose fossils are found in the Makapansgat assemblage, have shown that these scavengers do, in fact, accumulate large numbers of bones in their breeding lairs. It now seems highly probable that they were more important as bone-collectors at Makapansgat than hominids had been. Brain, 1997, p.82
However, it will always be to Raymond Dart's credit that he embarked on a pioneering taphonomic investigation years before the basic principles of cave taphonomy had been formulated. Brain, 1997, p. 83

Everyone know this, do they? That’s a bold assertion you’ve made, and not for the first time. It’s actually a pillar in your claim of spear use back into the Pliocene. A review of the literature before you ejaculate such nonsense would prevent this embarrassment. But, one of the things I noted about your posts is you don’t mind looking the fool. Repeatedly.
The_Metatron wrote: So, after a very brief search through the literature, I find this paper from 2021, in which we find:Together, our primary and extended analyses suggest that humans, or more precisely that estimated changes in human population levels, had little bearing on North American megafauna population levels, but that decreases in global temperature had an overall negative impact on megafauna population levels. (Stewart et al., p. 4)In summary, the results of our quantitative analyses are consistent with climate-driven declines in North America’s megafauna populations. Data quality issues aside (see Introduction), using the largest assembled database of directly dated megafauna, we found no through-time relationship between megafauna and human population levels. While this does not preclude humans from having had an impact—for example, by interrupting megafauna subpopulation connectivity or performing a coup de grâce on already impoverished megafauna populations—it does suggest that growing populations of “big-game” hunters were not the primary driving force behind megafauna declines and extinctions. Instead, we found a consistent positive correlation between megafauna population levels and the NGRIP climate proxy. In other words, decreases in global temperature correlate with decreases in mega- fauna population levels. (Stewart et al., 2021, p. 10)
In terms you may understand, humans, with their spears, did not “decimate the megafauna”. Climate shift did.
Enjoy your usual look.
Jayjay4547 wrote:The substantive issue is my rational explanation for that absurd denial: that the market place for human origin stories told in the name of science has been the site for building the origin story of man as a god; a conscious being who is a first cause, not made by anything prior.
The fossil record and the theory of evolution should provide the very worst context for building such an origin story but human ingenuity in story making seems be to equal to even that task.
Evidence that Fenrir denies is all about that context:
The agility of baboons in avoiding predation by leopards by climbing in trees.
The agility of leopards in hunting baboons in trees.
The aggression of baboons in mobbing a leopard on the ground.
The quick thinking of a leopard to assess its danger from baboon teeth and escape from a mobbing.
The agility of a gazelle in escaping from a leopard.
The short canines of Australopithecus, showing that they could not bite a leopard.
The short toes of Australopithecus showing that they did not have the agility of either leopard or baboon in a tree.
The thick legs of Australopithecus showing that they could not escape by running from a leopard.
The big hoof-less feet of Australopithecus showing that they could not kick a leopard
The use of sticks by chimpanzees against a leopard
The hugely effective use of spears by Australopithecus descendants.
There is an ugly and dangerous common thread in denying evidence like this: a contempt for Nature, and an overweening assertion of the uniqueness and effectiveness of human intelligence.
The Metatron wrote: No, the contempt is reserved for you, JJ. As for the singularly effective human intelligence, the proof is in the pudding, isn’t it? The only species that came close was h. neanderthalensis and they are gone, aren’t they? Who’s left? Us. Only us.
The_Metatron wrote: You know what it looks like? Australopithecines were on the menu. Looks like the species was able to survive by being able to move (bipedalism), and able to live in areas not favored by the big predators. You do know they didn’t have to achieve perfect success in predator avoidance as a species. Their species had to have a reproductive rate that exceeded their appearances on the menu. Here you are, displaying your ignorance in full bloom. Looks like the australopithecines won.
They didn’t use bone tools, even the likes of your hero Dart didn’t want to try to assert they made and used wooden weapons.

Shall we talk about that spear use now? I’ll make this easier for you. Here are some pictures:
Compared to a chimpanzee, with hands similar to A. Afarensis:
It isn’t a question of weight ratios, it’s a question of how they could grip it. Oh, Milks went on in her thesis to thoroughly test thrusting spears, throwing spears, and various grips. The sort of work I suggested you attempt. Too late, it’s already been done by your betters.
Here is a conundrum: how come Lucy was too stupid to make a simple wooden spear, when the bird brained Cape Penduline Tit can make a nest out of specialised material, with an entrance mouth glued shut using spider web, and a fake entrance to an adjacent fake empty nest, which will protect the chicks from a predating snake?

The_Metatron wrote:When you are surprised, when you have under two seconds to react to an attack as you suggest, you might have time to get your hands on the spear you didn’t know how to make. Then, it’s too late. If you are sprinting away from such an attack, your thrusting spear is useless to deter that attack.
The_Metatron wrote:Dart did claim a. Afarensis used bone tools. He was wrong. Washburn questioned it. Brain showed that hyenas make caches of bones, exactly like the ones Dart claimed were made entirely by australopithecines. Exactly. No bloodthirsty little cannibal australopithecines needed.

Cito di Pense wrote:Recent discussions have been steered toward picking and choosing data in attempts to show that hominins of several million years ago were somehow specially-equipped to combat predation sufficiently to avoid extinction. As noted by other posters, JJ's focus on predation is fixated on technology-as-guarantor even at such an early stage. No effort is made to show that escaping predation is the only necessity for survival.
Cito di Pense wrote:What a myopic bunch of tripe, because JJ's narrative assumes that the appearance of hominins is taken for granted or even as intended by cosmic forces, accompanying an obsession with the unrecognized genius of Raymond Dart. Packaged along with that is a bunch of nonsense about the "northern" vs. "southern" conception of hominid evolution. Not only do we have a creationist component, but a jingoistic one, as well.

That's you looking at adaptations through your god-goggles, so you talk about "means" (that is, designs). The behavior persists not because it was designed to thwart an enemy and it's not a learned behavior; it persists because its outcome is better reproductive success; offspring who inherit the genetic patterns that produce this behavior increase the chance their offspring will have it, too, by sexual reproduction.

You argue nothing with the dimwit and demonstrably inapt example you make of it. You practice apologetics. You persist in your dimwit mistake of treating the outcomes of adaptations as pieces of some grand design. Anything to banish chance. Your lame excuses are nothing but the rickety framework of a very determined and dogged creationist ideology.
