Researchers have been studying the discriminating potential of human scent for over three decades. A 1988 experiment demonstrated that a dog could distinguish identical twins living apart and exposed to different environmental conditions by their scent alone. This is a feat that could not be accomplished using DNA evidence, as identical twins share the same genetic code.

Wow. 

Now all we have to do is have a scent capturing device for crime scenes and we don’t need DNA if it’s not available.

Fascinating stuff, imho.
