Whether mankind is really that different from other creatures on the planet is a debate as common as a late night conversation. Apparently the DNA of humans and dung beetles are 90% similar. There seem to be ways for apes, whales, and Golden Retrievers to communicate. And with the benefit of retrospect, one can trace a family tree from the earliest hominids to modern man on a poster in a sixth grade science fair.
But the common arguments focus on our construction, bill of materials, and certain skills... the hardware, if you can bear the metaphor. But the software -- essentially what happens on that hardware -- seems to have some unique characteristics in humans. Specifically, it appears that to be human means you are creative, and you make promises. And as I hope to explain below, if only humans can make promises, only humans can make commitments to the actions required to secure the well-being of another... in more common terms, only human beings can love. And finally, if humans are uniquely creative, then only humans can discern a sense of purpose. It is this combination of creativity, promise, love, and purpose that then are the fuel for our sense of what ought to be. I believe it is why one ponders can reasonably ponder whether humans are the only truly moral creatures.
I must say that I'm not the first to have thought these things. Apparently Frederich Nietzsche, in his work on the Genealogy of Morals, stumbled into the same question of making promises. He argued that to survive, humans need to be able to forget, but that unlike cattle, they do remember and make commitments. I liked the way Sunny Auyang's explained this in her book, Mind in Everyday Life and Cognitive Science:
Nietzsche (1874) observed that it is possible to live and live happily without memory, like grazing cattle blissfully oblivious of the past or future, but to live without forgetfulness is as impossible as to live without sleep. The strength of forgetfulness makes more remarkable the genealogy of morals, which culminates in the autonomous and responsible individual with the right to make promises. Only animals with logos can promise. A promise is a choice made in the present. It implies not merely the the passive inability to forget an utterance, but the active memory that must hold through all the vicissitudes between the initial "I will" and its final discharge Our full-blown mental capacity manifests itself in the will to remember, the confidence to promise, and the assurance to foresee one's own ability to stick to his freely given words. As Nietzsche (1887:II.1) wrote: "To breed an animal with the right to make promise -- is not this the paradoxical task that nature has set itself in the case of man? Is it not the real problem regarding man?"
To paraphrase Timothy Keller, in his book, The Meaning of Marriage, consider this: To stand at the altar and make the wedding vows is not simply to say, "I love you today and I'm willing to say that in front of my mother-in-law and a few hundred others." Rather it is to intentionally promise to love regardless of circumstances. It is something I will do in the future. It is a promise that includes the calculus of intent (I will) and capability (I can) and desire (I want to). But interestingly, at least in traditional marriage, I will and I can have a future tense orientation, and I want to is in a present tense. It is to say, I want to now, and I will in the future regardless of whether I want to then. That is the nature of a promise and it appears that only humans can do this.
Stuart Briscoe, has often repeated this definition of love. "To love is to be preoccupied with the well-being of another regardless of their position or response." This definition eliminates a sentimental love that is blind to reality because it is aware of the other's position and response. Though it is not in the definition itself, the implication is that we make promises, perhaps implicitly, to act in a way that benefits another. Note that it is not reciprocal... I will regardless of whether you. What makes it compelling is its unconditional nature and how starkly it stands in contrast with a simple conditioned response that will behave lovingly when it is suitable. Love intends. Furthermore, it intends to be durable.
From the concept of promise, let's move to creativity:

Andy Crouch's book, Culture Making: Recovering our Creative Calling, makes roughly this argument: If you look at the apes, they've been eating bananas for millenia in the same way: peel of the skin, swallow the insides. But mankind has developed thousands of alternative banana-eating approaches from Bananas Foster to peanut butter and banana sandwiches. (My analogy, not Crouch's.) Crouch suggests this, if in the beginning God created, and if God created mankind in his own image (Gen 1:26), then mankind was created to be creative. (By the way, this is not the main point of Crouch's book. His main point is really that we can have either a posture of creativity in a way that is consistent with our creation, or we can have a posture of critique in a way that is consistent with our cultures, and he urges us to the former.)
Leslie Newbigin, former Bishop of the Church of South India (and contemporary of CS Lewis) in his book, Foolishness to the Greeks: Gospel and Western Culture, argues that modern constructions of how things work miss the point of why they work. He uses the analogy of a speaker at a podium. With all of the mechanics and software of modern technology, one could build a machine that could reproduce the motions of the tongue, lips, lungs and vocal chords and nearly reproduce the actions of the speaker. But the purpose of the speech would still be a mystery. To understand the actions of mankind requires that one understand his purposes. Viktor Frankl, in his writing, Man's Search for Meaning, recounts his time caring for others as a Nazi prisoner. He observed that man can endure hardships of every kind -- deprivation of food, sleep, rest, relationship -- but once a person loses purpose or hope, they will die within 48 hours. The awareness of purpose, and its cousin hope is an essential element of what it means to be human.
Of course, for Christians, of which I am one, the catalog of the last half dozen paragraphs, resonates like a kind of modern echo of the texts of the Old and New Testaments. God is portrayed as a covenant maker (promise), creator (creativity), agape-er (love), and the ultimate source of purpose. It is not my intent to write an argument for the veracity of the scriptures; others have done a more complete job here than I will. Rather, I argue that these scriptural descriptions of God -- promise, other-focused love, creativity, and purpose -- are the building blocks of the uniqueness of humankind. One can observe them objectively, describe them metaphorically, experience them personally, and connect them historically and theologically. But it is impossible to reproduce them outside of mankind.
In fact, the argument that mankind is more than just an incremental evolutionary step away from other creatures may be the best we can do when our tools are those of a biologist. But the demonstrated nature of humans is dramatically distinct in its foundation. To explore the distinction can be an adventure. To ignore it is willful deception.
