humanity is "special"
We're the only animals with opposable thumbs
"Many non-human animals also have some kind of opposable thumb or toe."
You are right, interesting. Still, in your source it clearly states that the only animals to have "fully" opposable thumbs are humans, which still makes us special.
Similar arguments would claim many species to be equally special.
Elephants are the only living species with such long tusks. Kangaroos are the only animals fighting standing on their tail. Platypus are the only mammals laying eggs.
The argument is too complex. You can switch to list view.
