宠物可以将人类DNA转移到表面 协助犯罪调查 Pets can transfer human DNA to surfaces, aiding crime investigations.

根据Flinders大学和维多利亚警察局2026年的一项研究,家庭宠物,特别是狗和猫,可以通过短暂互动,作为刑事调查中的沉默证人,转移人类DNA。 Household pets, especially dogs and cats, can transfer human DNA through brief interactions, acting as silent witnesses in criminal investigations, according to a 2026 study by Flinders University and Victoria Police. 研究发现,宠物可以携带非所有者的DNA,包括嫌疑人的DNA,并将其传播到表面,有可能将个人与从未接触过的犯罪现场联系起来。 The research found that pets can carry DNA from non-owners, including suspects, and spread it to surfaces, potentially linking individuals to crime scenes they never touched. 受控制的实验证实DNA从模拟罪犯转移到宠物,然后转移到环境,强调宠物是可能的生物病媒。 Controlled experiments confirmed DNA transfer from mock offenders to pets and then to environments, highlighting pets as possible biological vectors. 调查结果表明宠物可提供关键的法医线索,特别是在缺乏直接证据的情况下,敦促调查人员在犯罪现场分析中考虑动物。 The findings suggest pets may offer crucial forensic leads, especially when direct evidence is lacking, urging investigators to consider animals in crime scene analysis.
