When you find yourself, as I did a few days ago, spending a morning watching the absurdly long phalluses of ducks being coaxed from their nether regions, you can find yourself wondering how your life ended up this way. Fortunately, there is a higher goal to such weirdness. The phalluses of ducks are just the tip of an evolutionary iceberg. The female ducks have their own kinkiness, too. It’s all part of a fierce avian battle of the sexes.

For the latest, see my article in tomorrow’s New York Times. The paper on which it is based appears in the open-access journal PLOS One.

Here’s a story that should be getting lots of press but apparently isn’t: a new study indicates that plants don’t release lots of methane gas.

You may perhaps recall a lot of attention paid to methane from plants back in January 2006. A team of scientists (mostly from the Max Planck Institute for Nuclear Physics)reported in Nature that they had found evidence that plants release huge amounts of the gas–perhaps accounting for ten to thirty percent of all the methane found in the atmosphere.

Among the many obligations keeping me away from the blog is the nearly-completed overhaul of my web site, carlzimmer.com. Along with information on my books and talks, the site also has an archive of the past few years of my articles. I’ve made my way back to 2001, and I am continuing to push back further. It’s a strange experience to look back over many dozens of stories that all seemed rather cutting-edge at the time. In some cases, they’ve been outstripped so starkly by later research that they seem almost like time capsules now. In other cases, further research hasn’t really pushed the boundary of knowledge much more.

It’s getting harder and harder to remember what it was like to write about science in the pre-Web 2.0 days. Back then (i.e., 2004), I’d come across an intriguing paper, I’d interview the authors, I’d get comments–supportive or nasty–from other experts in the field, and then publish an article distilling everything I’d learned. It would take months or years for the authors to follow up on their work or for other scientists to publish their own papers attacking or supporting the original research.

Trace your genealogy back 25 million years, and you’ll meet long-tailed monkey-like primates living in trees. Those primates were not just the ancestors of ourselves, but of all the other apes–chimpanzees, bonobos, gorillas, orangutans, and gibbons–along with the monkeys of the Eastern Hemisphere, such as baboons and langurs. By comparing ourselves to these other primates, scientists can get clues to our evolution over the past 25 million years. Until now, most of those clues have come from fossils and studies on the behavior and physiology of apes and monkeys. But in the past few years scientists have begun to pore over a new record: the one that is inscribed in our genome and the genomes of other apes and monkeys.
