Since the tardy 1800s , we ’ve known that other character of human being once roamed our planet . At that time , scientists accredit that fogy unearthed in caves across Europe belonged to archaic humans now eff asNeanderthals . Over that time , our sympathy of Neanderthalshas undergone dramatic turmoil .

In the early 1900s , scientist conceived of Neanderthals as apelike and almost bestial . But in the preceding few decades , unambiguous evidence has indicated that our closest human congener mated with us at multiple points in prison term . artifact found at several sites suggestNeanderthals may even have had esthetical labor .

Ludovic Slimak , an adventurer and archaeologist at the Centre for Anthropobiology and Genomics of Toulouse in France , has been spellbound byarchaeologysince he was 5 and has spent more than 30 years hound for our closest human relation in caves on nearly every continent . He talk with Live Science about his unexampled ledger , " The Naked Neanderthal : A New Understanding of the Human Creature " ( Pegasus Books , 2024 ) , about why Neanderthals are not only another version ofHomo sapiens , what their mating with modern world tells us about our first and last coming upon with them , and what they unwrap about our own human nature .

Archaeologist Ludovic Slimak has spent 30 years studying Neanderthals.

Ludovic Slimak : I must have been maybe 18 years old . So very , very ahead of time , I spent a lot of time track this kind of human . I wrote my first book , " Naked Neanderthal , " after more than 30 eld of seeking for those creatures .

[ There ’s a ] certain perceptual experience of a Neanderthal like a beast , or since 20 to 40 years [ ago ] in Europe , we have another perception of Neanderthals like another " ourselves . " And I recollect , after working so many times on millions of Neanderthal tools , searching for them in caves everywhere , I think that all that was just ill-timed .

The important thing about this book is that , with my very accurate knowledge of these population , I use Neanderthals to endeavor to understand what we are — us , sapienson Earth . By defining " What is a Neanderthal ? " in fact , I created this mirror that allows us to sing about us , and to define us and to understand what we are and where finally we are going .

TG : The range of the Neanderthal when I was growing up was subhuman on some level . But in late years , we ’ve learned that Neanderthal man and humans mated at multiple points . Not only did they couple , but obviously those offspring went on to have children such thatour DNA has their DNA in it . How do you think that ’s changed our intellect of who they were ? Or does it ?

LS : We use the fact that — look , allsapienstoday , to different degrees , we all have a certain degree of Neanderthal DNA — and [ use it to say ] , " OK , so they did not vanish . We all come up together , and we created a novel humanness . "

And , in fact , that ’s not what it ’s saying , the DNA , at all . When you are searching for ancient DNA [ from 40,000 to 45,000 year ago ] … all these earlysapienshave recent Neanderthal DNA , and that ’s why we have [ Neanderthal DNA ] today . But when you reach and you test to extract DNA from the last Neanderthals , contemporary of these earlysapiens — let ’s say between 40,000 and 50,000 years ago — there ’s not a single Neanderthal withsapiensDNA .

And this is something incredibly important in term of cultural anthropology , because the exchange of gene is never a making love affair . In every traditional guild , it ’s the question of the identities we are move to build between two mathematical group , and that ’s what we call patrilocality .

When two populations are near to one another but they are very distinct — maybe they can have a different language and different traditions , they are in neighboring territory — they are going to exchange their char . That means that the women have the mobility ; that stand for that my sister will go into your radical …

Here we see a reconstruction of our human relative Homo naledi, which has a wider nose and larger brow than humans.

TG : They do to a place to splice and have kids , right ?

LS : … But if we do that , your baby will come into my group , and with that , we will become brothers , and we will come all together and become one big and more potent group . That ’s something universal in anthropology .

And we bang also by DNA that this question of patrilocality , the mobility of women , was also the same thing for Neanderthals .

But when we see what happen at the present moment of the contact , we see that allsapienshave Neanderthal DNA , and there ’s not a single Neanderthal withsapiensDNA.This is a major issue to interpret the extinction and the exact fundamental interaction between the two populations .

Your sister , your neandertal sister , will come with me among mysapiensgroup , but my babe wo n’t fall with you . It ’s very rare , but it happens when there ’s a entire war between two populations . And in that case , you regard that the other group are the transgressors of certain taboos and they are no recollective human race . You will drink down everybody , but you will keep the children , the woman with you .

I do n’t say that there was genocide at all here betweensapiensand Neanderthals . That could have happen in sealed region , but I do n’t call back that ’s the process of defunctness of Neanderthals .

What could have happened ? I think that , OK , they have exchanged their sisters . But the genetic differences between the two population were so important that then they must have strain and it did not bring . And we jazz by DNA that when these two universe met together and they had children — and these children , if they were male , they were sterile or they could n’t make it . And so I think that the population tried a lot to exchange and to have alliance between the populations , and that simply did not work on .

TG : So are you saying that all of the mating would have been between Neanderthalian women run toHomo sapiens’communities , suffer female children , and then those are the only children who passed on their genes ?

LS : It ’s very potential that we have a physical process that must work like that . But we also , of course , must keep in mind that our understanding , the economic value of ancient DNA , is very fond .

TG : Are there any artifact or discoveries that you think give clue about their finish ?

LS : The first thing we must realize is that the archeological data are very , very racy . If you ’re concerned to understand " Who were the Neanderthals ? " they pass on behind them jillion and 1000000 and millions of tools and weapon system and flint factor . In fact , we have too much data , and we are not able to analyze everything .

But the problem we had when working on all these millions of objects is that each clip , we do n’t really " see " Neanderthals .

Circular alignment of stones in the center of an image full of stones

I ’ll give you a very mere example so you could understand . You have a go at it that I set up the very firstHomo sapiensin Europe , continental Europe . I find stay that areolder than 54,000 years old , while we [ previously ] thought thatsapienscame 45,000 years [ ago to Europe ] .

We have there , also , thousands of objects that were abandoned by these very earlyHomo sapiens . When we take these tools , they are made of flint [ points ] , like the tools made by Neanderthals . When I analyze them , they are all the same . That means that if you saw a hundred of these points , and the 10,000 after that , they are all the same . If you take measuring rod at 1 - millimeter [ precision ] , they are all the same .

But when , now , you ’re dealing with Neanderthal tools and weapon , there ’s something very important . Each of these are telling . They are very dainty , like the craft of theHomo sapiens . Each of these objects are totally different . That means that each physical object is unique .

It ’s as if the artificer , the Neanderthal man , when he take away the flint , the in the buff fabric , the boulder , he began to craft . But before that , he looks at the morphology , he looks at the texture , he looks at the color — and , according to that , is going to change his projection . And every object will be unequaled . There ’s an incredible creativeness there .

So what did we have at the moment of contact ? It ’s not a supercreativeHomo sapiensthat encountered an inferior creature . We had what would have been the brush of us , a superefficient tool , with them , a supercreative animate being . This efficiency , the normativity , the uniformity is something major that definedHomo sapiens , and that ’s the message of my Holy Writ .

There ’s something unsafe amongHomo sapiens . I do n’t say that to say , " man sapiensis a very spoiled puppet on Earth . " The skirmish between the Neanderthal andsapienswas not the encounter between full and evil .

It ’s potential that we were so efficient … [ that ] by our simple presence on the same district , they have disappear like a moving ridge . We were , we are , not evil . We are just what we are , biologically .

We are still this über - efficient animal . And actually , what we see is that we are destroying our planet , not because we are malefic but because we are too efficient . We are destroying all the biodiversity not because we desire to ruin the planet but because we ca n’t do anything about our own style to be humans .

We can fight that . Our cultures can transform .

There ’s something in us which is very particular , which is very dangerous . But we can change it , and we can only change it if we realize it and if we put words on it .

For over a hundred we saw Neanderthals as inferior to Homo Sapiens . More recently , the pendulum swing the other agency and they are broadly regard as our relatives : not quite human , but like enough , and still not equal . Now , thanks to an on-going revolution in human palaeontology in which he has dally a central part , Ludovic Slimak shows us that they are something totally different – and they should be understood on their own terms rather than by compare them to ourselves . As he reveal in this sensational Word , the Neanderthals had their own history , their own rituals , their own customs . Their own intelligence information , very different from ours .
