Patterns
have been noticed on people’s fingers
|
|
|
|
for
many years. In the mid 1600s, Marcello
|
|
|
|
Malpighi first described the patterns of ridges
|
|
|
|
and
pores on the tips on the fingers, as part of a
|
|
|
study
on the human skin.

In
1823, the physiologist Jan Evangelista
|
|
|
|
Purkinhe described whorls, ellipses and
|
|
|
|
triangles
formed by the lines of the ridges and
|
|
|
|
grooves
on the surface of the skin on the
|
|
|
|
fingers.
