We do have our opposable thumbs and highly-developed vocal chords, and we know how to use them.
On top of that, the human species possesses the advantage of collective intelligence: especially since the Industrial Revolution, each member of our species performs a specialized task, which contributes to our species producing more and more crap.
To our detriment, we have high levels of anxiety, depression, ennuie, and other psychiatric illnesses of which more feral species seldom suffer, except when confined in a zoo.
After the next world war, though, we will revert to a feral state, and few (if any) of us will survive.
Individual octopi are probably more intelligent than individual humans, but lack our collectivist instinct.
Ants and bees have the collectivist instinct, but lack individual intelligence.
Whales have intelligence and collectivist instincts, but lack our opposable thumbs.
