Cannot direct evolution

Can direct evolution

Example: Body weight, knowledge, sense of humor, etc

Example: Color of eye, color of skin, hair type , etc.

Traits acquired during the lifetime of an individual do not reflect in the reproductive tissues

Changes in the non-reproductive tissues are not passed on to the DNA of the germ cells and  therefore not inherited by the next generation.

Example: The change in body weight of beetles due to starvation is not passed onto the next generation since it does not make any change in the germ cells of the beetle.
