There was a doctor at Auburn University. He directed a deer study project that may still be going. He was/is one of the most knowledgeable guys in the field of deer and deer biology I have ever run across.
In 1995, a plantation with which I was associated was one of the places he studied. That year, I killed a relatively large buck-large in terms of both antlers and body weight. The doctor came to age him. The buck had an 18”-spread, I commented that we seldom kill a wide-racked buck and we killed about 400-deer a year. His reply was that we were hunting thick swamp deer and deer in the thick swamp seldom had wide racks because they had adapted traveling in the thick cover.
That is the basis for my original statement. I stand by it. But…as swamps and other forms of thick cover are logged and cleared; and as sub-species inter-breed and move, this is less of a hard fact.
Antlers are governed by genetics-age-nutrition. As I stated, we can impact age and nutrition. Only evolution impacts genetics. In every specie, there are anomalies-animals that defy the norm. A wide-racked buck from the deep swamp. An albino etc. But all warm-blooded animals are impacted by the three rules I stated previously. They impact body characteristics. Why would we then suppose there is not a similar connection to antlers?
That is my final statement on this subject.
