Last October, a lawsuit was leveled against an evolution web site at UC Berkeley, based on the claim that government funds had been used to promote religious belief. I contributed the section on the history of biological thought. Judy Scotchmoor, the project’s coordinator, just dropped me an email letting me know that the judge has dismissed the case. One less frivolous lawsuit clogging the courts. I’ve got to run, but if I get more information later, I’ll update this post.

Pregnancy can be the most wonderful experience life has to offer. But it can also be dangerous. Around the world, an estimated 529,000 women a year die during pregnancy or childbirth. Ten million suffer injuries, infection or disability.

To David Haig, an evolutionary biologist at Harvard, these grim statistics raise a profound puzzle about pregnancy.

“Pregnancy is absolutely central to reproduction, and yet pregnancy doesn’t seem to work very well,” he said. “If you think about the heart or the kidney, they’re wonderful bits of engineering that work day in and day out for years and years. But pregnancy is associated with all sorts of medical problems. What’s the difference?”

Natural selection can favor genes that allow children to grow up healthy. But in order to grow up healthy, they need nurturing from their mothers, both before and after birth. If a baby’s development puts a strain on a mother, she may end up having fewer children. That means she may spread fewer copies of her genes to later generations . That creates conditions in which natural selection may also genes that allow mothers to restrain their children. Our particular way of having kids puts genes in conflict.

How do we know that we are kin to chimpanzees and howler monkeys and the other primates? For one thing, it’s by far the best explanation for the fossil record. For another, our DNA shows signs of kinship to other primates, much like the genetic markers that are shared by people from a particular ethnic group. There’s a third line of evidence that I find particularly fascinating: the viruses carried by humans and other apes.

It would be hard to imagine a better time for these two important books to appear. The science of global warming has been making dramatic headlines. NASA scientists recently reported that 2005 was the hottest year on record. Researchers studying the oldest core of Greenland ice yet extracted have also reported that there is more heat-trapping carbon dioxide in the atmosphere now than at any other point in the past 650,000 years. The vast majority of climate scientists agree that if we continue pumping greenhouse gases into the atmosphere the world’s temperature will climb significantly, and new computer models project a grim scenario of droughts and rising sea levels.
