For Jack Sepkoski (19481999),
who brought me one of the greatest possible joys
a teacher can ever earn or experience:
to be surpassed by his students.
Offspring should not predecease their parents,
and students should outlive their teachers.

but Jack was born to set the order of lifes history right
and he did!

P REFACE
In the fall of 1973, I received a call from Alan Ternes, editor of Natural History magazine. He asked me if I would like to write columns on a monthly basis, and he told me that folks actually get paid for such activities. (Until that day, I had published only in technical journals.) The idea intrigued me, and I said that Id try three or four. Now, 290 monthly essays later (with never a deadline missed), I look only a little way forward to the last item of this extended seriesto be written, as number 300 exactly, for the millennial issue of January 2001. One really should follow the honorable principle of quitting while still ahead, a rare form of dignity chosen by such admirable men as Michael Jordan and Joe DiMaggio, my personal hero and mentor from childhood. (Joe died, as I put this book together, full of years and in maximal style and grace, after setting one last recordfor number of times in receiving last rites and then rallying.) Our millennial transition may represent an arbitrary imposition of human decisions upon natures true cycles, but what grander symbol for calling a halt and moving on could possibly cross the path of a mans lifetime? This ninth volume of essays will therefore be the penultimate book in a series that shall close by honoring the same decimal preference lying behind our millennial transition.
If this series has finally found a distinctive voice, I have learned this mode of speech in the most gradual, accumulating, and largely unconscious manner against my deepest personal beliefs in punctuational change and the uniquely directive power (despite an entirely accidental origin) of human reason in evolution. I suppose I had read a bit of Montaigne in English 101, and I surely could spell the word, but I had no inkling about the definitions and traditions of the essay as a literary genre when Alan Ternes called me cold on that fine autumn day.
I began the series with quite conventional notions about writing science for general consumption. I believed, as almost all scientists do (by passively imbibing a professional ethos, not by active thought or decision), that nature speaks directly to unprejudiced observers, and that accessible writing for nonscientists therefore required clarity, suppression of professional jargon, and an ability to convey the excitement of fascinating facts and interesting theories. If I supposed that I might bring something distinctive to previous efforts in this vein, I managed to formulate only two vague personal precepts: first, I would try to portray all subjects at the same conceptual depth that I would utilize in professional articles (that is, no dumbing down of ideas to accompany necessary clarification of language); second, I would use my humanistic and historical interests as a user friendly bridge to bring readers into the accessible world of science.
Over the years, however, this mere device (the humanistic bridge) became an explicit centrality, a feature that I permitted myself to accept (and regard as a source of comfort and pride rather than an idiosyncrasy to downplay or even to hide) only when I finally realized that I had been writing essays, not mere columns, all alongand that nearly five hundred years of tradition had established and validated (indeed, had explicitly defined) the essay as a genre dedicated to personal musing and experience, used as a gracious entre, or at least an intriguing hook, for discussion of general and universal issues. (Scientists are subtly trained to define the personal as a maximally dangerous snare of subjectivity and therefore to eschew the first person singular in favor of the passive voice in all technical writing. Some scientific editors will automatically blue-pencil the dreaded
