Identifying People By Odor As Effective As Fingerprinting
A study has found that everybody has a unique body odor, like their fingerprints, that could be used as an unique identifier. The study showed that a persons unique odor stayed the same even if they varied their diet with strong smelling foods such as garlic and spices. "These findings indicate that biologically-based odorprints, like fingerprints, could be a reliable way to identify individuals," said Monell chemist Jae Kwak. I would have thought that hundreds of years of dogs tracking people would have proved this, but it's nice to know that science has figured it out officially now.
the idea that fingerprints are unique is stupid, especially for anyone who is actually in law enforcement or forensics. you need 12 count it TWELVE different points of matching to even get a fingerprint submitted for evidence. so if this odor is just as effective that means its pretty much a scare tactic as much as "we got your fingerprints at the scene!" is
Do identical twins put off the same odor?
In Berlin, Germany during the cold war era, the Stasi (Big Brother Police) knew this! They could track individuals with smell. In fact they have a room FILLED with little jars of every citizens' personal smell! I've been there and seen the rooms. They had special dogs trained for this too. They would open the jar and let the dog smell some... then go out into the city and find this person, they had a good success rate too which is kind of surprising. They would even track people by spraying different pheromones on their target.
