If two faces can be exactly similar, why two fingerprint can’t
be similar
Our fingerprint started to develop at the age of around 10
weeks
You get your own fingerprint around 4 month
age
Middle layer of skin, Basal layer grows faster during this time
Basal layer strains against its neighbor for
space as it grows faster. Pressure causes skin to
fold
epidermis
Basal layer
Dermis
These folds are random
Folds in skin
First faint line appear on skin because of folding of skin
Fetus touches its surroundings
and those simple touches
also help to create
fingerprint patterns
Random pattern of folds on skin changes with every
touch
Difference in activity of fetus, condition inside the womb causes
the difference in fingerprint
No match
Even twins in same womb don’t do same activities, neither their skin folds in same pattern
Fingerprints don’t change
with age
Because this folds go deep into dermis
No proper fingerprint because of rare genetic condition
•Adermatoglyphia
•Dermatopathia pigmentosa reticularis
