"...among the joyous, heartless, ever-juvenile eternities, Pip saw the multitudinous, God-omnipresent, coral insects, that out of the firmament of waters, heaved the colossal orbs. He saw God's foot upon the treadle of the loom, and spoke it; and therefore his shipmates called him mad."

They say that history is written by the winners, but if that's true, then natural history is written by those who can write. Our ancestors split from the ancestors of chimpanzees some 6 or 7 million years ago, and since then they've given rise to perhaps twenty known species of hominids (and potentially many more waiting to be discovered). Today only our own species survives, and only ours has acquired the intelligence to learn things about the distant past--such as the fact that we are the product of evolution. Our survival and our intelligence sometimes blur together, with the result that a lot of the research on human evolution (and most of the popular accounts of it) revolve around what makes our own lineage unique and successful. All the other branches of homind dynasty become our foil--the losers who, through their extinctions, reveal what is most glorious about ourselves. As a way of thinking, this is both unfair and foolish. We become satisfied with our own false assumptions about other hominids, and may miss some lessons they have for us. Exhibit A: our ancient thick-headed cousin Paranthropus.

I can already see the grim look many Americans will have as they chew on their Christmas roast tomorrow. They'll be thinking about yesterday's report that a cow in Washington state tested positive for mad cow disease. There's some comfort in knowing that so far it's just a single cow, and that American cattle are regularly screened for bovine spongiform encephalitis. The grimmest look this Christmas may be on the faces of McDonald's shareholders and cattle ranchers. A single Canadian cow that test positive wreaked havoc on the entire beef industry up north. But this Christmas also brings a fascinating discovery about the bizarre agents that cause disorders such as mad cow disease: they may actually record our memories.

Evolution isn't simply about the genes you gain. It's also about the genes you lose.

I will never figure out the publishing world. My new book, Soul Made Flesh officially publishes on January 6, 2004. But Amazon and Powell's both say they've got it now and can get it to customers in 1-2 days. I...

Just before the winter solstice brings autumn to an end, here's a chance to blog about the great evolutionary biologist--and student of fall foliage--William Hamilton. Hamilton, who died in 2000, has never reached the household-name status of other evolutionary biologists...

Here's a new development in the search I described last week for the genes that make us uniquely human. Science's Michael Balter reports on a new study about a gene that's crucial for making big brains. Mutant versions of the...

Darwin's spirit lives on in everything from the Human Genome Project to medicine to conservation biology--the three topics I covered in my post on Friday. It also lives on in brain scans. While Darwin is best known for The Origin...

In a post last month, I pointed out how aerospace engineers can learn a lot from looking at the fossils of ancient flying reptiles. Today's issue of Nature contains a variation on that theme: ancient swimming reptiles can teach geneticists...

Two decades ago, a neuroscientist named Benjamin Libet published a classic experiment on conscious will. He had his subjects rest a finger on a button as they stared at a specially designed clock. It had only one hand, which swept...
