We now know hexenbiest can be created. We also know hexenbiest can shape shift. It seems the wesen are a physical manifestation of your inner self. From Juliette results we see shape shifting can have residual effects. Putting this together,  hexenbiest where created using magic. The hexenbiest then cast shape shifting spells on people to bring out their inner beast. It was these creations the hexenbiest used for their wesen natural abilities. Such abilities would be eisbiber being great builders, blutbad being great hunters. The hexenbiest then needed to create grimms to control the wesen.

Just a darwin theory of wesen evolution.
