"Changes our DNA" as said above by MagentaStudios, is too vague. If the
change is a methylation pattern of DNA in a somatic cell and no
parallel change exists in a germ line cell that could be passed to
offspring then this is not going to be akin to what people think of
when the term Lamarckian is used. There must be a way for epigenetic
(epigenomic?) change to impact the germline to qualify. Otherwise it's
just another developmental change that stays in the individual affected
and goes no further.
