Implicating gibbon → ape
Link to implication

Reason:

Gibbons (also known as lesser apes) are apes in the family Hylobatidae.

Also suggest implicating:

• lar_gibbon -> gibbon

Should we make a distinction between apes and lesser/great apes? Ditto with monkeys and old world/new world monkeys.

Regardless of whether we decide on using greater and lesser ape tags or not, the blonde furred lar_gibbon should definitely imply gibbon. It's one of the more well known of the gibbons.

Might also be wise to implicate siamang to gibbon, as it seems to be the only gibbon species whose common name isn't "* gibbon", even if it is currently unused.
