It does however get to the nit of your ignorance. The procedure you describe is the basis for much of The Origin Of the Species. The process/procedure is Selection, man made selection and thus not natural selection, and thus not evolution.

In the present if you observe carefully, it is used by dog breeders to produce yapping little psuedo-kids.
