Environments without oxygen are excellent for the preservation of soft parts: no oxidation, no decay by aerobic bacteria. Such conditions are common on earth, particularly in stagnant basins. But the very conditions that promote preservation also decree that few organisms, if any, make their natural home in such places.

A project like the Burgess revision has potentially flashy and predictably less noticeable aspects. Both are necessary. A conventional reporter will convey only the hot ideas and the startling facts — Hallucigenia gets ink, the Burgess trilobites get ignored.

But the Burgess oddballs mean little in isolation. When placed in an entire fauna, filled with conventional elements as well, they suggest a new view of life. The conventional creatures must be documented with just as much love, and just as assiduously — for they are every bit as important to the total picture.

I suggest that the true Darwinian spirit might salvage our depleted world by denying a favorite theme of Western arrogance — that we are meant to have control and dominion over the earth and its life because we are the loftiest product of a preordained process.
