Experiences of an individual during its life time are in the somatic cells of the body. That is, in non-reproductive tissues that cannot be passed to the next generation. Thus, they cannot contribute directly in evolution.
For inheritance of traits over generations and involvement in direct evolution, they must be passed to the DNA of the germ cells (reproductive tissues). The characteristics of DNA are passed to the progeny and also can play direct role in evolution.
