This describes the daily life of innumerable animals which do little
else besides chewing. Why do you want the word "heavy" before the
"chewing". The diet of male gorillas appears to be mostly leaves,
rather than stalks. Female gorillas don't need such massive jaws
although they have an identical diet. The difference in jaw size
and structure has to come from some difference in role, or in
general morphology.

Let's have a little more thought and a little less abuse.
