These species are actually changing, but in what ways?
Are we ultimately harming the species through selective breeding for a single genetic trait (large antlers)?
I would also stake the farm on it that if you compared a whitetail skeleton (or it's closest forefather)from 1 Million years ago
Anything over the course of time changes.
Are we harming the species, well I'm not, but if your referring to the selective breeding farms, Only time will tell
So my question is are there any cases of whitetails pertaining to your original question. No! Evolution, which I believe Does not exist, Would theoretically have to happen over the course of years and years and years! So their could be no cases to the fact we have no knowledge of the living breathing species of whitetail before the last thousand years.
There is no possible answer to the originall question
How are Whitetails evolving? ... And if they are changing, how fast are they evolving?
Are they getting taller? Faster?Are their brains getting bigger? Are their senses becoming more keen? Is selective breeding (whitetail farming) having an impact? Is Vomolfaction a newly-developed characteristic?
