First of all deer are plenty smart the way they are and we dont need to allow evolution to let them get any smarter.

Second areas that produce huge deer consitently (Iowa, Illinois, Kansas, Texas etc.) do so because of huge ginormaous pieces of land that see next to no hunting pressure, not QDM.

If i had a 3000 acre ranch in texas, I could shoot spikes and forks and there would still be trophy deer because there is no way I could shoot all the bucks by myself, several would survive to 3.5+.
If you live in one of those states, you have no idea what hunting pressure is, hunt in WI, PA, MI or NY then we'll talk.
