Science moves forward by flow. One experiment leads to another. Observations accrue. What seem like side trips or even dead ends may bring a fuzzy picture further into focus. Yet science often seems as if it moves forward one bombshell at a time, marked by scientific papers and press conferences. I can’t think of a bigger contrast between the bombshell illusion and the flowing reality of science than the day in 2000 when President Clinton announced the completion of the first draft of the human genome on the White House lawn. He declared it “an epoch-making triumph of science and reason.”

Perhaps the notion of conservatives building an alternative to Wikipedia that includes many “scientific” entries based on creationist books aimed at seventh graders sounds like some bizarre hoax. For those who doubt, there’s now audio evidence.

National Public Radio ran a segment yesterday in which they interviewed the founder of Conservapedia, Andrew Schlalfly. The interviewer, Robert Siegel, got right to the point. He described Wikipedia’s entry on kangaroos, which includes details about extinct species of kangaroos known from fossils.

Dinosaurs had small genomes. At least some of them did–the ones that gave rise to birds. If you have access to Science, you can read my News Focus article on the new field of “dinogenomics.” As I mentioned last week, my web site carlzimmer.com is in serious overhaul, so as soon as it’s ready, I’ll post a copy of the article there, too.

But if you’re at all curious about the secret that pubic lice have been keeping for over three million years, the tale of a mysterious liaison between our ancestors and the ancestors of gorillas–read on.

Many parasites tend to stick close to their hosts. A parasitic wasp may wander through forests and fields to find a caterpillar from a single species of butterfly in which it will lay its eggs. Blood flukes taste the water of their ponds for molecules from human skin.

The Eastern Arc Mountains of Tanzania may not be terribly tall — only half the height of their famous neighbor, Mount Kilimanjaro. But to scientists who tally the planet’s biodiversity, they tower over the rest of the world. The forests that cover their flanks contain the highest density of endangered animals anywhere on earth.

“This is a really important place,” said Neil Burgess, an expert on the Eastern Arc Mountains at the University of Cambridge and the World Wildlife Fund. “Biologists who go there just keep finding more and more species.”
