Scientists have been able to collect and analyze detailed genetic data from human DNA from all these places, raising thorny ethical questions about consent, privacy and security when it comes to our biological information. Environmental DNA has been obtained from air, soil, sediment, water, permafrost, snow and ice cores and the techniques are primarily being used to help track and protect endangered animals. However, the ability to capture human DNA from the environment could have a range of unintended consequences — both inadvertent and malicious, they added. They termed this information “human genetic bycatch” and decided to study the phenomenon in greater depth. We cannot avoid shedding DNA in the public space,” Moreau, who was not involved in this study, said via email.
