- Adapting to artificial changes to environment/constraints requires a long time to evolve and that will be through countless generations. So, the example above needs to be thought of through large numbers instead of such a small sample. - Additionally, consider that you could perhaps fool a duckling to imprint upon someone/something else as his/her mother. This one example is not useful if one were to attempt to disprove that this imprinting behaviour evolved to help the ducklings stay with their mother in a vulnerable period. To me, this appears clear. However, I am not sure if I've articulated it in a way where you are able to also see where I am going with this. Cheers
