Why Humans Are Exceptional

Biologist Ann Gauger holds the heretical opinion, at least it's heretical in today's cockeyed culture, that among all life forms, human beings are exceptional. Here's a quick summary of some of the traits she lists as making us not just different from other mammals but radically, qualitatively different:

We have specific traits that are well outside the norm, so far outside the norm that some scientists see the gaps as unbridgeable. These include abstract thought, foresight, speech, art, music, sociality, theory of mind, manipulation of the material world, charity, wickedness, and religion.

There may be others I haven’t thought of. We see rudiments of these things in animals, but human abilities are orders of magnitude higher than animals (or lower in the case of wickedness). Our specific abilities are greater than are necessary for survival, so unless they are linked to other traits why should we have a Mozart or an Einstein or a Galileo? What we do as scientists is pretty esoteric, right? Is there a selective advantage to any of it?

Maybe at low levels, but being Shakespeare or understanding the molecular dynamics of ribosomes or however you would describe your work is purely gratuitous.

In other words, it's hard to see how or why natural selection would have sorted out from among our primordial ancestors a few who possessed the capacity to do calculus.

One of the most inexplicable uniquely human traits is our capacity for language. Gauger quotes the late psychologist David Premack who challenged anyone to:

...reconstruct the scenario that would confer selective fitness on recursiveness. Language evolved, it is conjectured, at a time when humans or proto-humans were hunting mastodons…Would it be a great advantage for one of our ancestors squatting alongside the embers, to be able to remark, ‘Beware of the short beast whose front hoof Bob cracked when, having forgotten his own spear back at camp, he got in a glancing blow with the dull spear he borrowed from Jack’?

Human language is an embarrassment for evolutionary theory because it is vastly more powerful than one can account for in terms of selective fitness. A semantic language with simple mapping rules of a kind one might suppose that the chimpanzee would have, appears to confer all the advantages one normally associates with discussions of mastodon hunting or the like.

For discussions of that kind, syntactical classes, structure-dependent rules, recursion and the rest, are overly powerful devices, absurdly so.

Gauger also cites an abstract from a scientific article on language evolution at the website Scorched Earth which concludes that there's simply no evolutionary explanation for human language:

We argue ... that the richness of [speculations about how language evolved] is accompanied by a poverty of evidence, with essentially no explanation of how and why our linguistic computations and representations evolved.

We show that, to date,

(1) studies of nonhuman animals provide virtually no relevant parallels to human linguistic communication, and none to the underlying biological capacity;

(2) the fossil and archaeological evidence does not inform our understanding of the computations and representations of our earliest ancestors, leaving details of origins and selective pressure unresolved;

(3) our understanding of the genetics of language is so impoverished that there is little hope of connecting genes to linguistic processes any time soon;

(4) all modeling attempts have made unfounded assumptions, and have provided no empirical tests, thus leaving any insights into language's origins unverifiable.

Based on the current state of evidence, we submit that the most fundamental questions about the origins and evolution of our linguistic capacity remain as mysterious as ever, with considerable uncertainty about the discovery of either relevant or conclusive evidence that can adjudicate among the many open hypotheses.

So, there is no plausible naturalistic explanation for how language arose in human beings, just as there's no plausible naturalistic explanation for the origin of life, or the origin of human consciousness, the origin of biological information or even for biological processes like meiosis, mitosis, metamorphosis, or sexual reproduction.

Nor can naturalism provide us with a satisfactory scientific account of cosmic fine-tuning or moral obligation.

When confronted with the most fundamental ontological questions naturalism simply shrugs its shoulders, and yet we're told by some that naturalism is nevertheless the most rational position to hold. Its chief competitor, the belief that there's an intelligent mind underlying the cosmos and all that it contains, we're told, is mere superstition.

We might be forgiven for suspecting that between these two worldview alternatives - unconscious, purposeless forces or an intelligent purposeful mind - the latter is actually the more rational explanation for the phenomena Gauger lists and the former is the more superstitious.
