Chronicling the passage of whales has led me to an understanding that we, as a species, now sand at a crossroads. We can face the possibility of our own extinction and work to avert it, or we can flow the more traditional path of earths organisms and fall blindly over the edge. If there's one trait that characterised human beings, it's the will to survive. This, I believe, will motivate us to work with the natural world rather than opposite it, which is all we need to do to give the children of earth - of all species - the opportunity to thrive.

The zoologists who came from Germany to inseminate the elephantwore bicycle helmets and protective rubber suits.So as not to be soiled by effluvium and excrement,which will alchemize to produce laughter in the human species,how does that work biochemically is a questionto which I have not found an answer yet.

Perhaps if zoologists would contemplate the wide variations presented by many plants of indubitably one and the same species, and the still wider diversities of long cultivated races from an original stock, they would find more than one instructive parallel to the case of the longest domesticated of all species, man.

A multitude of harlequin lifeforms bobbed and twirled and played in the depths of the Atlantic. Pink cucumbers with thorny backs. Algae. Starfish. Annelids with simple brains and a hundred toes. Sponges—like yellow, swollen hands—sucked in water and pushed out oxygen. Most amusing were the mysterious buggers who had no likeness on the previous earth; tiny beasts with exotic exoskeletons engraved with deep grid-like patterns, snails with horns, and slithering plants that looked like magenta weeping willows.

The obsession with putting ourselves at the centre of everything is the bane not only of theologians but also of zoologists.

There are 2,500 kinds of sponges, all of them consist largely of holes.

Infant wart hogs resemble both sides of the family.

Whales are silly once every two years. The young are called short-heads or baby blimps. Many whale romances begin in Baffin's bay and end in Procter and Gamble's factory, Staten Island.

Places of confinement providing free food and medical care are called prisons.

The zoologist is delighted by the differences between animals, whereas the physiologist would like all animals to work in fundamentally the same way.

Have pity on them all, for it is we who are the real monsters.

We see, then, that even from the zoological point of view, which is the least interesting and—note this—not decisive, a being in such condition can never achieve a genuine equilibrium; we also see something that differs from the idea of challenge-response in Toynbee and, in my judgement, effectively constitutes human life: namely, that no surroundings or change of surroundings can in itself be described as an obstacle, a difficulty, and a challenge for man, but that the difficulty is always relative to the projects which man creates in his imagination, to what he customarily calls his ideals; in short, relative to what man wants to be. This affords us an idea of challenge-and-response which is much deeper and more decisive than the merely anecdotal, adventitious, and accidental idea which Toynbee proposes. In its light, all of human life appears to us as what it is permanently: a dramatic confrontation and struggle of man with the world and not a mere occasional maladjustment which is produced at certain moments.

Branches or types are characterized by the plan of their structure,Classes, by the manner in which that plan is executed, as far as ways and means are concerned, Orders, by the degrees of complication of that structure, Families, by their form, as far as determined by structure, Genera, by the details of the execution in special parts, andSpecies, by the relations of individuals to one another and to the world in which they live, as well as by the proportions of their parts, their ornamentation, etc.
