But here I stop—short of any deterministic speculation that attributes specific behaviors to the possession of specific altruist or opportunist genes… - Stephen Jay Gould

I am not unmindful of the journalist's quip that yesterday's paper wraps today's garbage. I am also not unmindful of the outrages visited upon our forests to publish redundant and incoherent collections of essays; for, like Dr. Seuss' Lorax, I like to think that I speak for the trees. Beyond vanity, my only excuses for a collection of these essays lie in the observation that many people like (and as many people despise) them, and that they seem to cohere about a common theme—Darwin's evolutionary perspective as an antidote to our cosmic arrogance.

Nearly anyone in this line of work would take a bullet for the last pregnant dodo. But should we not admire the person who, when faced with an overwhelmingly sad reality beyond personal blame or control, strives valiantly to rescue whatever can be salvaged, rather than retreating to the nearest corner to weep or assign fault?

The contingency of history (both for life in general and for the cultures of Homo sapiens) and human free will (in the factual rather than theological sense) are conjoined concepts, and no better evidence can be produced than the “experimental” production of markedly different solutions in identical environments.
