The language of DNA is written in a four-letter alphabet. The four different chemical units of DNA (called nucleotides) create an incomprehensibly vast range of possibility codes. Consider a short sequence of 41 nucleotides. There are over 4.8 trillion trillion possible sequences it could take. In this vast universe of possibilities, how can natural selection hit on new DNA sequences that help life survive?

Cut-and-paste creationism?
Yesterday I pointed readers to a column attacking evolution by Jack Kemp on the web site Town Hall. Today a sharp-eyed commenter pointed out that it is almost entirely identical to a column from Phyllis Schlafly from August 16 on the Eagle Forum. I don’t know if these pages are going to be pulled down or otherwise altered if word gets out, so here’s a screengrab of Kemp and of Schlafly. It looks pretty much word for word identical to me. You be the judge…

Scoop up some dirt, and you’ll probably wind up with some slime mold. Many species go by the common name of slime mold, but the ones scientists know best belong to the genus Dictyostelium. They are amoebae, and for the most part they live the life of a rugged individualist. Each slime mold prowls through the soil, searching for bacteria which it engulfs and digests. After gorging itself sufficiently, it divides in two, and the new pair go their separate, bacteria-devouring ways.
From his latest column:
Liberals see the political value to teaching evolution in school, as it makes teachers and children think they are no more special than animals. Childhood joy and ambition can turn into depression as children learn to reject that they were created in the image of God.
He may not be in office any more, but this piece wins Kemp an honorary spot in the creationist-friendly political pantheon.

I’m happy to report that the eyes are back.
My third book, Evolution: The Triumph of an Idea, came out in 2001. It’s a survey of the history and cutting edge of evolutionary biology, from the origin of new species to mass extinctions, from the rise of complex life to the emergence of humans. The book explores evolutionary races between hosts and parasites, between males and females. It puts evolution in a historical context as well, showing how Darwin’s theory emerged out of the science of his time and how social and political tensions foster hostility to evolution today. Scientific American called it “as fine a book as one will find on the subject.” (More information, as well as an excerpt, can be found here.)
