After a shower/bath/swimming/washing dishes etc,etc...?

It seems a great scientific topic around here!

The water is to blame... it gets into the callus of the skin, softens and enlarges it. The skin on your fingertips is esp. thin so the effect is most noticeable, but it happens everywhere on your body.

What I want to know is why those wrikles so resemble

a brain coral.

What's the smiliarity of pattern here and why ??

The science of pattern formation deals with the visible, (statistically) orderly outcomes of self-organisation and the common principles behind similar patterns.

In developmental biology, pattern formation refers to the generation of complex organizations of cell fates in space and time.

WOW ! This is interesting stuff, RD thanks for that link. [

Wiki says
"Pattern formation is controlled by genes" so I guess here is a quite visible example what we have in common with brain corals.

ps: I find your quoted sentence fascinating. Biology meets physics.
Oh I wish sometimes I could go back to studying full time.....
