The items you have presented as evidence are interesting and possibly indicative of the conclusions you have drawn, but not conclusively so.

Diet, environment, genetic predisposition, age... all factors that are easily identified as being related to the size of an animal and you seem to have ignored or excluded all except the one that leads to the conclusion you desire.
