Researchers Say Humans Didn’t Wipe Out the Neanderthals

new xmen neanderthals

I thought the idea that humans killed off the Neanderthals was already losing currency. And now a paper published in the journal Molecular Biology and Evolution casts more doubt on that particular hypothesis.

i09′s Alasdair Wilkins summarizes:

A team of Spanish and Swedish researchers say that new DNA evidence paints a far grimmer view of the state of Neanderthals. Their analysis suggests the Neanderthal population had crashed 50,000 years ago, and a relatively small band of survivors then recolonized central and western Europe before their final end 20,000 years later. In a statement, Love Dalén of the Swedish Museum of Natural History explained what they discovered:

Instead the paper’s authors suggest climate change had a greater impact on neanderthals than previously thought.

Alasdair Wilkins writes: “This also raises the question of just how humans would have really fared against a Neanderthal population at full strength. I’m sensing some pretty serious alternate history fodder here…”

Uncontacted Tribe in South America Goes Missing

 Uncontacted Tribe in South America Goes Missing

Bad news. Remember that uncontacted South American tribe? (Covered here and here.) They’ve gone missing after narco traffickers wiped out the guard post protecting the tribe. Observers fear the worst.

The Brazilian guard post protecting the uncontacted Indians who were filmed from the air earlier this year has been over-run by heavily-armed men, suspected to be drug-traffickers. It has been ransacked and vital equipment destroyed.

Fears are now mounting for the welfare of the Indians after workers from FUNAI (the government’s Indian Affairs Department) found one of the traffickers’ rucksacks with a broken arrow inside. A rapid survey by government officials has shown no trace of the Indians, who made worldwide headlines in February.

Humanity’s Next Evolution May Be Mental, Not Biological

  • Posted on February 28, 2011 at 12:24 pm

Mark Changizi, author of the upcoming book Harnessed: How Language and Music Mimicked Nature and Transformed Man, writes:

Where are we humans going, as a species? If science fiction is any guide, we will genetically evolve like in X-Men, become genetically engineered as in Gattaca, or become cybernetically enhanced like General Grievous in Star Wars. [...]

Simply put, none of these scenarios are plausible for the immediate future. [...]

We have already been transformed via harnessing beyond what we once were. We’re already Human 2.0, not the Human 1.0, or Homo sapiens, that natural selection made us. We Human 2.0’s have, among many powers, three that are central to who we take ourselves to be today: writing, speech, and music (the latter perhaps being the pinnacle of the arts). Yet these three capabilities, despite having all the hallmarks of design, were not a result of natural selection, nor were they the result of genetic engineering or cybernetic enhancement to our brains. Instead, and as I argue in both The Vision Revolution and my forthcoming Harnessed, these are powers we acquired by virtue of harnessing, or neuronal recycling.

In this transition from Human 1.0 to 2.0, we didn’t directly do the harnessing. Rather, it was an emergent, evolutionary property of our behavior, our nascent culture, that bent and shaped writing to be right for our visual system, speech just so for our auditory system, and music a match for our auditory and evocative mechanisms. [...]

The road to Human 3.0 and beyond will, I believe, be largely due to ever more instances of this kind of harnessing. And although we cannot easily anticipate the new powers we will thereby gain, we should not underestimate the potential magnitude of the possible changes. After all, the change from Human 1.0 to 2.0 is nothing short of universe-rattling: It transformed a clever ape into a world-ruling technological philosopher.

Seed: THE NEXT GIANT LEAP IN HUMAN EVOLUTION MAY NOT COME FROM NEW FIELDS LIKE GENETIC ENGINEERING OR ARTIFICIAL INTELLIGENCE, BUT RATHER FROM APPRECIATING OUR ANCIENT BRAINS

neanderthal New Evidence Suggests Neanderthals Cooked and Ate Vegetables

Researchers in the US have found grains of cooked plant material in the teeth of the remains.

The study is the first to confirm that the Neanderthal diet was not confined to meat and was more sophisticated than previously thought.

The research has been published in the Proceedings of the National Academy of Sciences.

The popular image of Neanderthals as great meat eaters is one that has up until now been backed by some circumstantial evidence. Chemical analysis of their bones suggested they ate little or no vegetables.

New Interview with Cyborg Anthropologist Amber Case

cyborg anthropology New Interview with Cyborg Anthropologist Amber Case

Cyborganthropology.com, Cases website dedicated to the subject, identifies three categories of human-machine combo: “cybernetic organism”; “hybrid of machine and organism”; and “creature of both fiction and lived social reality.

“Case believes its the increasingly mobile internet and its ability to act as an extension of the brain—to store and share unique information with increasing automation and independence—thats turning more and more people cyborg. As Case says, shes not talking about Terminator, shes talking about the Facebook wall and the Twitter stream; how these technologies give us the ability to create an external version of our personalities with which others can interact in our physical absence.

She borrows the term “second self,” originally coined by sociologist Sherry Turkle, to describe this unique digital existence.”When people first went online, they had avatars and fake names and silly pictures and would play around with… multiple identities and it wasnt a big deal,” explains Case. “It was fun, it was play. Now, peoples identities are tied. You sign up to Facebook with your real name.

“Not only does the modern internet user create a second self thats more closely related to the person behind the machine, but their relationships with their computing devices are becoming more intimate. An integral aspect of Cases cyborg studies is to track these changes.

Why War? Biological vs. Cultural Explanations

  • Posted on November 11, 2010 at 7:24 pm

Fighting

John Horgan, writing for Scientific American, asks the big question: why do humans wage war? He’s previously rejected the “demonic males” theory, and has found Margaret Meade theory more satisfactory:

Many scholars solve this problem by combining Darwin with gloomy old Thomas Malthus. “No matter where we happen to live on Earth, we eventually outstrip the environment,” the Harvard archaeologist Steven LeBlanc asserts in Constant Battles: Why We Fight (Saint Martin’s Griffin, 2004). “This has always led to competition as a means of survival, and warfare has been the inevitable consequence of our ecological-demographic propensities.” Note the words “always” and “inevitable.” [...]

The best answer I’ve found comes from Margaret Mead, who as I mentioned in a recent post is often disparaged by genophilic researchers such as Wrangham. Mead proposed her theory of war in her 1940 essay “Warfare Is Only an Invention—Not a Biological Necessity.” She dismissed the notion that war is the inevitable consequence of our “basic, competitive, aggressive, warring human nature.” This theory is contradicted, she noted, by the simple fact that not all societies wage war. War has never been observed among a Himalayan people called the Lepchas or among the Eskimos. In fact, neither of these groups, when questioned by early ethnographers, was even aware of the concept of war.

In discussing the Eskimos Mead distinguished between individual and group violence. Eskimos were “not a mild and meek people,” she noted. They engaged in “fights, theft of wives, murder, cannibalism,” often provoked by fear of starvation. “The personality necessary for war, the circumstances necessary to goad men to desperation are present, but there is no war.”

Mead next addressed the claim that war springs from “the development of the state, the struggle for land and natural resources of class societies springing, not from the nature of man, but from the nature of history.” Here Mead seems to invoke Marx as well as Malthus. Just as the biological theory is contradicted by simple societies that don’t fight, Mead wrote, so the theory of “sociological inevitability” is contradicted by simple societies that do fight. Hunter–gatherers on the Andaman Islands “represent an exceedingly low level of society,” but they have been observed waging wars, in which “tiny army met tiny army in open battle.”

Amber Case

Grinding interviews cyborg anthropologist, and one of the most influential women in tech, Amber Case:

Reality is boring. Waiting in line at the DMV suck. Real life takes time. Digital life is more instantaneous. In real life, the time and space between goals and accomplishments is often large. For some, it is physically impossible to achieve certain things, like purchasing a Ferrari or rising above middle management in their career path. Online gaming, especially sites like Farmville step in to take care of that void. Whereas one doesn’t have the money, time or room for a real garden, Farmville provides one without the back aching labor. All reality is replaced by small icons, and time is compressed so that goals and accomplishments are right next to one another. Everything has a point value and a reward. When real life takes so long to reward someone, online gaming is often a better and more enjoyable alternative.

In the future, hybrid reality, or life which is both a game and real, might blot out the mild dystopia that we all live in. Or it will make us more intolerable of the space between reality. And for those who spend a lot of time in reality, Foursquare is a good add-on for making the mundane exciting. To be crass, one might say that Foursquare is kind of like dogs pissing on fire hydrants and having other dogs come along and sniff them to see who’s been there. The dog with the most potent urine is mayor of the fire hydrant.

Westerners vs. the World: We are the WEIRD ones

  • Posted on September 17, 2010 at 11:56 am

Joseph Heinrich conducts behavioural economics experiments in the countryside of southern Chile

The article, titled “The weirdest people in the world?”, appears in the current issue of the journal Brain and Behavioral Sciences. Dr. Henrich and co-authors Steven Heine and Ara Norenzayan argue that life-long members of societies that are Western, educated, industrialized, rich, democratic — people who are WEIRD — see the world in ways that are alien from the rest of the human family. The UBC trio have come to the controversial conclusion that, say, the Machiguenga are not psychological outliers among humanity. We are. [...]

Others punish participants perceived as too altruistic in co-operation games, but very few in the English-speaking West would ever dream of penalizing the generous. Westerners tend to group objects based on resemblance (notebooks and magazines go together, for example) while Chinese test subjects prefer function (grouping, say, a notebook with a pencil). Privileged Westerners, uniquely, define themselves by their personal characteristics as opposed to their roles in society. [...]

The paper argues that either many studies’ conclusions have to be retested on non-WEIRD cultural groups — a daunting proposition in terms of resources — or they must be understood to offer insight only into the minds of rich, educated Westerners.

Ancient Nubians Drank Antibiotic Beer?

ancient brew

A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer.

A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer. The finding is the strongest evidence yet that the art of making antibiotics, which officially dates to the discovery of penicillin in 1928, was common practice nearly 2,000 years ago.
The research, led by Emory anthropologist George Armelagos and medicinal chemist Mark Nelson of Paratek Pharmaceuticals, Inc., is published in the American Journal of Physical Anthropology.

“We tend to associate drugs that cure diseases with modern medicine,” Armelagos says. “But it’s becoming increasingly clear that this prehistoric population was using empirical evidence to develop therapeutic agents. I have no doubt that they knew what they were doing.”

How Technology Made Us Humans

  • Posted on August 31, 2010 at 4:01 pm

comingman How Technology Made Us Humans
The Man of Year Million

In his book, “The Artificial Ape,” anthropologist and archaeologist Timothy Taylor makes the startling claim that we did not make tools, tools made us.

He reminds us that the oldest stone tools we’ve found are 2.5 million years old. But the genus to which we belong, Homo, is only 2.2 million years old, at least according to the current fossil record. Our species, Homo sapiens, has been around for less time than the gap between tool creation and our genus.

In a fascinating interview with New Scientist, Taylor believes “earlier hominids called australopithecines were responsible for the stone tools . . . The tools caused the genus Homo to emerge.”

How does that reverse the human-technology equation? Taylor believes that the creation of tools – in his example a sling to carry an infant – is “how encephalisation took place in the genus Homo.” The creation of technology to take care of infants allowed them to be born more helpless. In other words, the development of initial tech allowed evolutionary forces to shape us in a particular fashion. In fact, perhaps forced them to do so.

ReadWriteWeb: How Technology Made Us Humans

Will our brains shrink due to our external ones? Not necessarily. The current trend is a demand for more and more intelligent and educated people to operate and program those machines. Even though I’d like to see computers get easier to operate and program, I would still expect see a demand for humans to do increasingly complex work with them.

Medieval Cyborgs – Artificial Memory as Mindware Upgrade

  • Posted on July 26, 2010 at 8:20 pm

Fuckin' RIFTS

Abstract:

The philosopher and cognitive scientist Andy Clark has argued that humans have always been ‘natural-born cyborgs,’ that is, they have always collaborated and merged with non-biological props and aids in order to find better environments for thinking. These ‘mindware’ upgrades (I borrow the term ‘mindware’ from Clark, 2001) extend beyond the fusions of the organic and technological that posthumanist theory imagines as our future. Moreover, these external aids do not remain external to our minds; they interact with them to effect profound changes in their internal architecture. Medieval artificial memory systems provide evidence for just this kind of cognitive interaction. But because medieval people conceived of their relationship to technology in fundamentally different ways, we need also to attend to larger epistemic frameworks when we analyze historically contingent forms of mindware upgrade. What cultural history adds to our understanding of embedded cognition is not only a recognition of our cyborg past but a historicized understanding of human reality.
