Yes exactly. Humans have different capabilities. Humans are different. Humans possesses the most complex nervous system on earth. Humans are 'smarter', 'more intelligent', 'more emotional', whatever words you want to use. Our nervous system is what makes us different to other animals.
The origins of consciousness and cognition is actually my central field of study. I serve on the editorial board of one central publication in the field and essentially referee for most of the other main players. It's actually a very contentious subject even among those doing the principle research on the matter, much less the lay public who may have other social, religious concerns wrapped up in it. Two conferences I regularly attend and present at are the ASSC:
http://www.theassc.org/, and the biennial Tucson conference:

But after 15+ years of arguing over it, I don't think I've made much headway on my position. The debate essentially boils down to a "continuity versus discontinuity" perspective, a term coined by Kathleen Gibson, an anthopologist and colleague of of one of my early mentors.

Sorry, I think the article may behind a paywall, but the gist of it is that the human brain and all other mammalian brains are remarkably similar in structure, with no unique structures or pathways distinguishing humans from any other mammal, let alone primates. Yet, our experience and patently obvious capacity for technological progress relative to even our closest primate ancestor put me squarely in the "discontinous" camp. However, you'd be surprised at the high volume of tenured professors and published scholars that continue to vociferously argue that we are none other than marginally smarter apes whose intelligence falls along a linear or "continuous" graph with all other mammal/primates according to gross brain volume (a measure known as the encephalization quotient (EQ).
So that's one reason I've stayed out of these discussions thus far, it's just very hard to sway opinion on this matter. It's going to take some extremely compelling study or model to even make a dent in public, even scientific opinion, and that might not even do much.
