No. Although recently a new field of reseach has sprung up in biology: epigenetics, the study of heritable changes that are not transmitted through RNA/DNA, this has little to do with Lamarck's theory.
Lamarck thought that evolution could be effected by changes in the body, rather that strictly by the survival (or rather the death) of offsprings.
