Pioneering flier Amelia Earhart disappeared over the Pacific Ocean in 1937 , and we ’ve been wondering about her fate ever since . A re - examination of a forensic analysis do in 1941 depict that bone found on a distant south Pacific island belonged to Earhart — a conclusion reached with a showy 99 percent number attached to it . doubter , on the other mitt , say the Modern depth psychology turn out nothing .
To chop-chop recap , Earhart was the first distaff flyer to fly alone across the Atlantic , but she cryptically melt in 1937 while flying over the Pacific with her navigator , Fred Noonan . Speculation emerged that her carpenter’s plane crash into the water , or the duo became stranded on an island , but trial impression has been lacking .
Richard L. Jantz , a forensic anthropologist at the University of Tennessee - Knoxville , trust Earhart became marooned , and he read he has the bones to try out it — or least , a forensic analysis of bones discovered on Nikumaroro island back in 1940 . You see , these “ Nikumaroro Bones , ” as they ’re ring , no longer exist . They ’re gone . go away . disappear without a touch . But before they went overlook , the bone were analyzed in 1941 by a doctor name D. W. Hoodless , who concluded that the bones — consist of a skull , lower jaw ( with no teeth ) , half a pelvis , and various arm and pegleg bones — belong to a scant , stocky , center - aged male , and not Amelia Earhart . [ A detailed account of the find and testing of the Nikumaroro bones can be found inthis 2016 Forbes clause ]
Jantz ’s young Forensic Anthropology bailiwick , titled “ Amelia Earhart and the Nikumaroro Bones : A 1941 Analysis versus Modern Quantitative Techniques , ” is precisely that — a re - depth psychology and inquiring of former - timey forensic technique using the modish that forensic science has to extend .
“ Forensic anthropology was not well developed in the former 20th hundred , ” writes Jantz in his newfangled newspaper . “ There are many example of erroneous judgement by anthropologists of the period . We can concur that Hoodless may have done as well as most analyst of the time could have done , but this does not mean his analytic thinking was right . ”
Among the various “ modern quantitative techniques ” used in the new analysis , Jantz used a software system computer program called Fordisc , which he himself co - developed . Fordisc , which is used by forensic scientist around the world , use “ statistical method acting to figure sexual urge , ancestry , and stature from skeletal measurement . ” The updated analysis “ reveal that Earhart is more like to the Nikumaroro bone than 99 % of mortal in a large character reference sample distribution , ” writes Jantz . “ This powerfully support the close that the Nikumaroro off-white belonged to Amelia Earhart . ”
In addition to this , Jantz compared the bone length with what ’s known about Earhart ’s forcible proportions . For case , the length of her humerus and forearm were infer from honest-to-goodness exposure of the pioneering pilot burner , and her inseam distance and waist circuit were forecast by valuate a duo of Earhart ’s trouser kept at Perdue University .
“ The fact remains that if the ivory are those of a thick male , he would have had bone lengths very similar to Amelia Earhart ’s , which is a low - chance event , ” conclude Jantz in the subject area . “ Until definitive grounds is presented that the remains are not those of Amelia Earhart , the most convincing literary argument is that they are hers . ”
It is not enough , he says , to say the bone belonged to a a compact male without specifying who that stocky male person might have been . “ This presents us with an untestable surmisal , not to mention uncritically set aside the prior data of Earhart ’s presence , ” he writes . That “ prior information ” include a piece of skid found near the remains , along with an empty sextant boxwood and a Benedictine bottle , both of which could have been included in Earhart ’s supplying .
“ I work out with Dr. Jantz for three age help him assemble the data for his study , so I ’m not surprised at the results — although the 99 percent certainty that the castaway was Amelia was a pleasant surprise , ” Ric Gillespie , Executive Director of TIGHAR , told Gizmodo . He say this subject field is the “ icing on the cake ” his team has been broil for the retiring 30 year . Gillespie and his colleague have been scouring Nikumaroro island in search of grounds that could finally show that Earhart was marooned there . “ Multiple lines of scientific grounds — radio propagation psychoanalysis , forensic tomography of historical photos , leave archival documents , archaeological discoveries , all channelize to the same conclusion , ” he said .
Kristina Killgrove , a biological anthropologist , is not so sure about the new interpretation .
“ base on the data point available , Jantz notes that he can not turn out Earhart as being a match for the Nikumaroro bone measurement data , ” she tell Gizmodo . “ This does not , of trend , have in mind that those bones are hers , although he seems to be positive they are based on statistic . ”
The new study does not make up the secret , says Killgrove , because no one know where the genuine os are . She points to this telling passage in Jantz ’s novel sketch :
If the skeleton were useable , it would presumptively be a relatively straightforward task to make a plus identification , or a authoritative ejection . Unfortunately , all we have are the meager datum in Hoodless ’s report and a premortem record gleaned from photographs and clothing . From the information uncommitted , we can at least offer an assessment of how well the bones fit what we can reconstruct of Amelia Earhart . Because the reconstructions are now quantitative , probability can also be gauge .
Without an available skeleton , argues Killgrove , the mystery will never be work .
“ What I would like people to know about this study is that it does not confirm the remains are hers — and that in fact there are no remains anymore , ” she told Gizmodo . “ Jantz has determined statistically that the near explanation for the measurement data is that they fit Earhart . But he also notes in the conclusion that it is unacceptable to test any other hypothesis . So the hypothesis that the bones are Earhart ’s can not be disapprove — but there are also no alternative hypotheses that can be tested . ”
Indeed , much of Jantz ’s psychoanalysis sound circumstantial , and without entree to the Nikumaroro off-white we ca n’t ever be 100 percent certain they belonged to Earhart . What ’s more , Jantz ’s analysis is heavy dependant on Hoodless ’ “ meagerly ” data — which Jantz used to counteract Hoodless ’s assessment and bolster his own hypothesis . certainly , the bones may belong to Earhart , but the mystery story is far from figure out .
