DNA pulled from thin air identifies nearby animals

[We Never Know]

Clare collected 72 air samples from both outside and inside zoo buildings. She used polymerase chain reaction to amplify the scant genetic fragments left on the filters into enough DNA for sequencing. “We had to take a leap of faith that it was there because it wasn’t something you can measure,” she says. After sequencing the eDNA, she matched the snippets to known sequences in a database. The team identified 17 species kept at the zoo and others living near and around it, such as hedgehogs and deer. Some zoo animal DNA was found nearly 300 meters from the animals’ enclosures. She also detected airborne DNA likely from the meat of chicken, pig, cow, and horse fed to captive predators indoors. All told, the team detected 25 species of mammals and birds.

Did they find any human DNA?

Heh... good question.

Did they find any human DNA?

I thought about that too but it didn't mention any.

I was surprised and pleased to find this is a research report. Thanks for posting it.

The article said... airborne DNA likely from the meat of chicken, pig, cow, and horse fed to captive predators...
I don't think they fed the animals on human.

Perhaps they will look a little closer at cases where DNA evidence is used to prove a case.
