Jeremiah asked the Naked Scientists:

What is the function of the marks which are the human palm (on the face of the hand)?

What do you think?

Easy.  To have our future predicted by wonderful gipsies!  [] [] []

They're just the crease marks formed from when you close your hand

But babies have them too, and some genetic conditions - like trisomy 21 - are associated with a single palmar crease, so it cannot be that simple. There must be a developmental reason for their presence.

Interesting. Maybe its to do with grip, like fingerprints
