...course, some people are naturally conservative; they avoid taking a position whenever possible. They just don't believe in going out on a limb when they don't know the genus of the tree. For these people, the vague generality must be partially junked and replaced by the artful equivocation, or the art of talking around the point...
...until 1975 that Rheumatologist Allen Steere, then at Yale, made sense of the malady. Steere investigated a group of children, in and around Lyme, Conn., who were suffering from a mysterious form of arthritis. He traced the outbreak to speck-size ticks of the genus Ixodes, carried mainly by mice and deer. In 1982 federal researchers isolated the culprit from the tick: a corkscrew-shaped bacterium, or spirochete, similar to the one that causes syphilis...

They just don't believe in going out on a limb, when they don't even know the genus of the tree.

...faster than they can be found and described. Naturalists have cataloged 1.6 million species, a small fraction of the estimated 4 million to 30 million that remain undiscovered. While most of these unknown species are insects, even a creature as garrulous and brightly colored as a parakeet of the genus Pyrrhura (its species name has not yet been assigned) eluded researchers until it was first sighted in Ecuador in 1980. "No one knows the diversity in the world, not even to the nearest order of magnitude," says Wilson. "We don't know for sure how many species there are, where...
