Michael worked as a fingerprint specialist at Scotland Yard for most of his working life.

Fingerprint evidence linking criminals to crime scenes has played a fundamental role in convictions in Britain since the first forensic laboratory was set up in Scotland Yard in 1901.

“No two fingerprints are ever exactly alike in every detail, even two impressions recorded immediately after each other from the same finger.

“It requires an expert examiner to determine whether a print taken from crime scene and one taken from a subject are likely to have originated from the same finger.”    Mike Silverman

Dermal ridges cover the palms and fingers of some animals, and these ridges form patterns known as fingerprints. The fingerprints of humans are unique; no individual person has exactly the same fingerprints as any other human. Perhaps unsurprisingly, unique fingerprints occur in most other primates, and sometimes occur in even more distantly related animals, such as koalas.
