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.
