In 2012 , the creative person Heather Dewey - Hagborgexhibited a workthat foreshadow a terrifying future : She extracted deoxyribonucleic acid from discarded hairs , gum and cigarette butts and used it to predict what those anonymous strangers might look like . The traces of ourselves that we are constantly leaving behind , she think , could let loose an era of biological surveillance in which little more than a hair could reveal a person ’s identity and locating .
Last workweek , the biotech firm Human Longevitypublished a paperclaiming that it can do just that . The paper has reach off an inter - science warfare .
Human Longevity , headed by famous genomics expert J. Craig Venter , lay claim that just by see at your DNA , it can craft a evenhandedly accurate model of your typeface . Human Longevity was working with safe deoxyribonucleic acid grounds than one would likely find on a coffin nail tail — using whole - genome sequencing , phenotyping and statistical clay sculpture , the company looked at 1,061 hoi polloi ’s DNA . About 70 percent of the time , they receive that their algorithm could aright identify the right person from a lineup of 20 photo of an ethnically - mixed chemical group .
Using genomic data , they foretell human face shape , eye color , pilus color and even what a person ’s voice might go like . The paper noted the potentially huge effectual and ethical implications of the work . If someone could really determine what you bet like from a DNA sample , it would mean that no deoxyribonucleic acid test would ever be truly private . Not to cite that police could plunk someone out of a lineup using little more than a free fall of stemma .
Criticism of the paper was swift . Columbia scientist and chief scientific ship’s officer of the family tree website MyHeritage.com Yaniv Erlich offered his ownrebuttal , argue that the paper used improper system of measurement and proficiency and “ does not really identify anyone . ” Erlichshot backthat the anticipation of his own grimace Venter tweeted looked more like Bradley Cooper .
Others speedily pile on . Skeptics pointed out that it seemed like the method really relies on traits like race and sexual practice to make photograph of medium fount , something that could be done using far simpler DNA tests . Indeed , when used to pick a specific lily-white European Isle of Man out of a lineup of 20 other exchangeable - looking men , it was right only 11 pct of the time .
4/ For the phonograph recording , I ’m with@erlichyaon this one . To show recognition from DNA , you have to … you have sex , actually identify someone .

The rebuttal paper inspired arebuttal to the rebuttalfrom Venter , who lay claim there were “ no major flaw ” in his work .
depend at the simulacrum , it ’s true that while the facial predictions bear resemblance to their owner , they do n’t seem quite accurate enough to clean someone ’s face out of a crowd .

But already , some companies are assign like dick to mold in the real humankind . A companionship called Parabon Nano - Labshas been work with policefor eld to avail clear cases by predicting the physical appearing and blood line of an unknown person via DNA . That technology , though , is little more than a high - tech interpretation of the composite criminal defendant sketch .
Venter ’s visual modality is likely inevitable . Certain evident characteristics , like eye colour , are call phenotype , and phenotypes are mostly determined by your deoxyribonucleic acid . The problem for now is that we have n’t quite picture how to read and understand all of that information . The science behind the applied science will in all likelihood have to improve before you could really pick someone out of a crowd base on genes alone .
In the meantime , for now you probably do n’t have to vex about a cigarette butt shove off your natural covering .
