No, temperature and nutrition doesnt change the DNA - but it can change 
the growth rate of the fingers and affect the way the genes are 
expressed. If you're interested in the effects of the environment versus 
the effects of the genes on an organism, well, you can join in on the 
debate (: People have been arguing about it for a long time. Do a google 
search for "nature versus nurture" and it will come up with a stack of 
info.
