So nothing scientific makes us different, that's fair enough. Something I can get behind. But there's an implication in there that we're not different which is patently not the case.
The properties that emerged from the tiny tweak our particular strand of ribonucleic ticker tape received made us very different. According to biology we are 97(ish) percent identical to mice. So why didn't mice develop the atom bomb?
You're a snowflake. Get over it
Actually, the implication is that we're no more different from all the other animals than any given species is different from all the other animals.
There is no big defining difference that sets us apart and makes us special. Our difference is the sum total of many traits that, in combination, characterize our species. The fact that we are the only highly technological species at this time sets us apart from the animals as much as the bat being the only flying mammal at this time sets bats apart from the animals. My point is that the man/animal dichotomy is false, and it's an unproductive way of thinking about our species and its relationship with all the other animals, and our shared environment.
