"According to the World Wildlife Fund, without human interference, one species would naturally go extinct every 27 years. But humankind has pushed the rate of extinction to a species every hour.
"No one seems to have noticed that, even at the lower 'natural' rate, at least one new species must have evolved every 27 years for us to exist. Where are the new ones? 'Evolvo Think' is such marvelous stuff. Things only need to be said, making sense isn't required." Tom Willis, ed. CSA News, 12(1):4.
BACK COVERThe back cover is a Hubble Space Telescope photo of comet Hale-Bopp which promises to be quite a bright comet early next year. The comet recently flared, ejecting some nebulous matter (like a tail) which is the large ball to upper left on the picture at right. The photo below shows how the comet looked when it first appeared.
