3. Open Your Catechism to Page One: The Fact of Evolution

So what is the “fact” of evolution? Timmer argues that “aspects of the theory [of evolution] can be safely treated as fact,” and in support of this point, cites a paper by the Canadian geneticist T. Ryan Gregory, entitled “Evolution as Fact, Theory and Path.”

Here is how Gregory (2008, 49) defines the “fact” of evolution:

2. Much Ado About A Footnote Citing Christian Schwabe

One theme of EE addresses differing views among evolutionary biologists about Darwin’s Tree of Life, i.e., the theory of the universal common ancestry of all organisms on Earth: more precisely, the monophyly of terrestrial life, rooted in the Last Universal Common Ancestor, or LUCA. While the majority position within evolutionary biology endorses monophyly, a growing minority of workers argue for multiple independent origins, or polyphyly (see below). It’s an important controversy, well worth the attention of textbooks.

This is the first in a series of blog entries replying to John Timmer’s online critique of the supplementary biology textbook Explore Evolution, posted by Paul Nelson on behalf of the book’s production team.

1. Introduction: Sending Him the Book Didn’t Help

On September 24, 2008, biologist and science writer John Timmer published an online review of the supplementary biology textbook Explore Evolution (EE). Timmer had previously written about EE without having read it, so Discovery Institute sent him a copy.

Does the biology textbook Explore Evolution manufacture false controversies about evolution, while ignoring real ones?

That’s what biologist and science writer John Timmer claimed in a post earlier this week at Ars Technica. Timmer attended a two-day symposium on evolution at Rockefeller University and noted the many debates brewing there. “Evolution clearly has no shortage of controversies,” he concluded . But those real controversies have “no overlap,” he claimed, with the “ostensible” (i.e., fake) controversies supposedly “manufactured” by Explore Evolution. Bottom line for Timmer: while students may, or may not, need to learn about controversies in evolution — he leans strongly towards “not” — Explore Evolution is misleading at best, and the academic freedom bills being introduced around the country aren’t needed.

Most people — including most professional biologists — think that one either accepts the neo-Darwinian theory of the universal common ancestry of life via undirected natural causes, or else one is a “creationist,” meaning someone who advocates multiple independent starting points for life, all of them specially created.
