If you&#x27;re looking to say humans are categorically different from every other animal -- that is, that we have something <i>none</i> of them do -- then you&#x27;re operating with such a level of granularity that it&#x27;s necessary that you overlook small differentiating factors. The issue is not &quot;why are humans unique, just like every species is unique&quot; but &quot;why are humans unique in a way no other species is?&quot;<p>And if you take a human and ignore their facility for language, you will essentially have a regular ape. If you take away our capacity for culture and technology, you don&#x27;t have an animal that rules the world uncontested. Whatever other differences we have are moot in comparison. (Take Stephen Hawking as an example.)
