Archaeologist and anthropologist Timothy Taylor explains how a long - vanished artifact explain human organic evolution and led to “ survival of the weakest . ”
You start out your Word of God The Artificial anthropoid by claim that Darwin was amiss . In what way ?
Darwin is one of my fighter , but I believe he was wrong in seeing human evolution as a effect of the same outgrowth that report for other evolution in the biological Earth – peculiarly when it come to the size of our cranium .
So you are saying that technology came before humans ?
The archaeological record show knap pit tool technologies earlier than 2.5 million eld ago . That ’s the smoke gun . The oldest fogey specimen of the genus Homo is at most 2.2 million years old . That ’s a gap of more than 300,000 years – more than the full length of clock time that Homo sapiens has been on the major planet . This suggests that early hominins called australopithecine were responsible for for the stone putz .
Is it potential that we just do n’t have a genus Homo fossil , but they really were around ?
Some researchers are holding out for an early specimen of genus Homo . I ’m trying to free us to suppose that we had Lucy Stone tools first and that those tools create a significant part of our word . The tools caused the genus Homo to come forth .
How do we know the chip stone were used as puppet ?
If you require to kill something or to fight yourself , you do n’t need a chipped stone tool – you’re able to just peck up a rock and throw it . With chipped stone , something else is going on , something called “ entailment ” : using one affair to make another . You ’re using some object to chip the Harlan Fisk Stone into a particular soma with the intention of using it for something else . There ’s an functional chemical chain – one dick entails another .
What were these puppet used for ?
Upright distaff hominins walking the savannah had a real trouble : their babies could n’t cling to them the way a chimp baby could cling to its mother . Carrying an infant would have been the highest waste pipe on energy for a hominin female person – higher than lactation . So what did they do ? I believe they figured out how to carry their newborns using a loop of animal tissue . grounds of the sling has n’t live on , but in the same direction that we infer lung and organs from the castanets of fossils that come through , it is from the stone putz that we can infer the bits that do n’t last : thing made from sinew , Sir Henry Wood , leather and grasses .
How did the slings mold our evolution ?
Once you have slingshot to hold babies , you have break a glass roof – it does n’t matter whether the infant is helpless for a mean solar day , a month or a year . you may have ever more helpless young and that , as far as I can see , is how encephalisation took place in the genus Homo . We used technology to wrick ourselves into kangaroos . Our children are bear more and more underdeveloped because they can continue to get outside the womb – they become an extra - uterine fetus in the sling . This means their mind can uphold to develop after birth , solving the smart bipedal paradox . In that sense engineering science comes before the ascent to Homo . Our mental capacity expansion only really engage off half a million years after the first stone peter . And they continued to acquire within an increasingly technical environment .
You compose in the Holy Writ that this led to a “ natural selection of the unaccented ” . What does this mean ?
Technology grant us to cumulate biological deficit : we lost our sharp fingernails because we had cutting tools , we lost our arduous jaw musculature thanks to Harlan Fiske Stone tools . These changes deoxidize our basic aggressiveness , increased manual sleight and made males and females more similar . biologic deficits continue today . For example , New human eyesight is on intermediate worse than that of world 10,000 year ago .
Unlike other creature , we do n’t adjust to environments – we conform environment to us . We just pass a tip where more people on the satellite live on in city than not . We are extended through our applied science . We now have it away that Neanderthals were symbolic creative thinker , belike made art , had exquisite shaft and big brain . Does that mean they were smart ?
Evidence shows that over the last 30,000 old age there has been an overall decrease in brain size and the trend seems to be continuing . That ’s because we can outsource our intelligence information . I do n’t need to remember as much as a Neanderthal because I have a data processor . I do n’t need such a dangerous and expensive - to - assert biology any more . I would argue that human being are conk to continue to get less biologically thinking .
If you said to me , you’re able to either have your toe hack off or your whole program library destroyed , with no chance of ever accessing those works again , I ’d say “ take my toes ” – because I can more easily compensate for that departure . Of course , you could get into a grisly argument over how much of my biology I ’d give up before I ’d say , “ OK , take the Goethe ! ”
Is human applied science really any different from , say , a bird ’s nest , a wanderer ’s connection or a beaver ’s decameter ?
Some biologists argue that human culture and engineering is simply an file name extension of biological behaviour and in that sentience humanity are like hermit crab or spiders . That ’s an idea known as “ niche adaptation ” . I see human technology as different because of the feeling of deduction . A bit of philosophers and social anthropologists have fence that the realm of artifice has its own logic – an thought that traces back to Kant ’s idea of the self-direction of the esthetical realm . Philosophy , nontextual matter history and paleoanthropology have to all arrive together for us to empathise who we are .
The point is , the realm of artificial things – that is , engineering – has a unlike productive pattern than the Darwinian pattern of descent with modification . citizenry like to argue that you could apply Darwinian natural selection to , say , industrial design . That led Richard Dawkins to propose and Susan Blackmore to develop the “ meme ” idea – ethnic analogues of genes that are not biological but they are still replicators and conform to the canonic logic of biological evolution .
I would contend that memes only do n’t make signified . And the understanding is that when you look at an stilted target like a death chair , for instance , there is no cardinal rule that defines it . There is no way to cast a definite philosophic boundary and say , here are the characteristics that are both necessary and sufficient to define a chair . The chair ’s meaning is lingual and symbolic – a chair is a chair because we intend for it to be a chair and we expend it in a particular way . stilted objects are defined in terms of intention and entailment – and that hit stilted things very different from biological thing .
People like Ray Kurzweil talk about an impending uniqueness , when technology will go on at such a rapid step that it will become level-headed and the world will become qualitatively different . Do you agree ?
I am sympathetic to Kurzweil ’s estimate because he is saying that tidings is becoming technological and I ’m enounce , that ’s how it ’s been from the head start . That ’s what it is to be human . And in that good sense , there ’s nothing scary in his imaginativeness of contrived intelligence service . I do n’t see any star sign of intentionality in car word now . I ’m not tell it will never happen , but I suppose it ’s a lot further away than Kurzweil tell .
Will computers finally be capable to develop their own computers that are even smarter than them , creating a sudden acceleration that leaves the biological behind and impart us as a kind of pond trash while the robots take over ? That scenario mean a sharp division between humans and our technology , and I do n’t think such a part exist . humanity are hokey emulator – we are biology plus technology . We are the first creatures to exist in that link , not purely Darwinian entities . Kurzweil says that the technological realm can not be deoxidise to the biological , so there we check .
At the end of the book , you note that there is no “ back to nature ” solution to climate alteration . Does that intend our specie was doomed from the start ?
The point is , we were never fully biologic entity , so there is no “ nature ” to go back to , for us . expect , you might ask , what about masses who “ live in nature ” , mass like the Aborigines in Tasmania ? In fact , the Tasmanians used technology to adjust and hold out and they might have done that for maybe another 40,000 years . The return is that their character of engineering – non - entailed – is not the style humans will live in the final scenario . Ultimately we take major progress – because even without climate alteration , the sun is eventually drop dead to blow up .
Now , you might retrieve that ’s a ludicrously long time away , but that ’s the variety of ridiculous timescale palaeoanthropologists call back about . I look back 4 million years and see our emergence and our organic evolution and then I look frontwards 4 million eld because those are the timescales I ’m used to . And in the long running play , homo will go nonextant if we ca n’t get off this planet . The only way out , ultimately , is up . The Tasmanians did n’t have the sort of technology that would lead them there , but we do .
