Study Uncovers , What Makes Fingerprints , Infinitely Unique.
'Science' reports that no two fingerprints
are ever the same, even in the case of identical
twins, and a new study aims to understand why.
According to the study, three families
of signaling molecules all interact
to create each unique fingerprint.
It is a great example of how
minor fluctuations … can generate
endless variations in a pattern, Roel Nusse, developmental biologist
at Stanford Medicine, via 'Science'.
'Science' reports that the uneven surfaces of fingers assist
with gripping and are not only found in humans, but also
in other climbing species like koalas and chimpanzees.

Those uneven surfaces of fingerprints
are what allow us to distinguish
the differences between textures.
Our fingerprints also form relatively
early during fetal development, beginning to
take shape around the 13th week of gestation. .
In a paper published in 'Cell,' scientists found that three
signaling pathways work together to control the formation
of primary ridges that develop into our fingerprints.

The individual uniqueness [of fingerprints]
comes from minute elements of the pattern.
Turing patterns readily produce
this type of fine-scale pattern, Denis Headon, geneticist at the University
of Edinburgh, via 'Science'.

Turing patterns occur in nature when overlapping
chemical activities give rise to complex patterns,
like stripes and spots in animal fur or on tropical fish.

'Science' reports that the results found that the overall
shape of the fingerprint pattern is dependent on the
anatomy of the finger and the timing of ridge formation
