If you want it to be done automatically when you first adjust an image, you can turn on "Automatically stack new versions" in the Aperture preferences.
If you want to do this manually, you can select an image that's been adjusted, then go to the Photos menu, then click on New Version from Original.

Aperture never changes your original. It just adds the editing info as "Versions." You can create as many versions as you like and the original/Master always remains available.
However in the strongest possible terms I recommend backing up originals on to separate external drives before involving with Aperture. Any workflow (even though the folks who write manuals include such workflows) that does not back up originals before entering an images management app is just wrong. We have seen hundreds of "Aperture ate my images" type comments here. All kinds of things can happen, mostly user error when workflows are improperly set up.
