I’ve been investigating a pseudo-Darwin quotation, “Not one change of species into another is on record … we cannot prove that a single species has been changed.” As I explained in part 1, and as the Talk.Origins Archive Quote Mine Project already disclosed, the second half is from The Life and Letters of Charles Darwin (1887), although the words are not Darwin’s but his son’s gloss. The first half, however, seems to have originated in Theodore Graebner’s Evolution: An Investigation and a Criticism (1921), which asserts, “Now, as a matter of fact, we cannot prove that a single species has changed” and then misquotes Darwin as saying, “There are two or three millions of species on earth, sufficient field, one might think, for observation. But it must be said to-day, that in spite of all the efforts of trained observers, not one change of species into another is on record.” The source of the first assertion is already known, but what about the passage misattributed to Darwin?

Last Tuesday afternoon, NCSE’s intrepid (but at the time, flu-ridden) communications director forwarded me an urgent request for assistance. Slate science editor Laura Helmuth was moderating a panel at the annual American Geophysical Union meeting in San Francisco, and one of her panelists had bailed. Could I step in tomorrow, to talk about opinion journalism for scientists and science journalists?

Over at the Talk.Origins Archive Quote Mine Project, there’s a brief discussion of a quotation supposedly from Darwin: “Not one change of species into another is on record … we cannot prove that a single species has been changed,” credited to My Life and Letters. Mike Hopkins and Mark VandeWettering correctly observe that Darwin never wrote such a book—although there is a book, assembled by his son Francis Darwin, with the similar title The Life and Letters of Charles Darwin (1887). They also correctly observe that the quotation appears on a plethora of creationist websites, to which I’ll add that it appears in a plethora of creationist books as well, the most recent of which (excluding self-published books) seems to be Robert Jeffress’s Outrageous Truths: 7 Absolutes You Can Still Believe (2008). (The sixth of the title’s purported truths is that evolution is a myth.) And they correctly observe that the second half of the quotation actually appears in The Life and Letters of Charles Darwin, although the words aren’t Darwin’s.

I want to start this week’s entry by saying that I really hadn’t intended this topic to take up three posts! It’s just that I kept adding and adding to make it all make more sense and before I knew it, I had 3000 words on dating fossils! Words fly when you’re geeking out…

A fossil!

This past week on Fossil Friday, I gave you a fossil and posed the question: animal, vegetable, or mineral? It turns out it was totally animal...indeed, an animal that we see even today. What was it? A locust from the Santana Formation in northeastern Brazil.

The Glass of Fashion title page

Provoked by a mention of a pseudonymous author, the Gentleman with a Duster, in the creationist Arthur I. Brown’s Evolution and the Bible (1922), quoted at length as complaining about the moral effects and scientific groundlessness of “Darwinism” in his The Glass of Fashion (1921), I decided to investigate. In part 1, I reported that the Gentleman with a Duster (used to clean the mirrors in the halls of power, as it happens) was the journalist Edward Harold Begbie (1871–1929). Since Begbie’s authorship of The Glass of Fashion was not revealed until after his death, Brown could, I suggested, be excused for not recognizing that the author lacked the scientific training to offer a really informed opinion about scientific grounds of Darwinism and for not realizing that he was already on record as accepting evolution, as in The Proof of God (1914), published under Begbie’s own name. I’ll add now that the author’s skeptical attitude toward the scientific bona fides of natural selection is also understandable.

A fossil!

This week I am at the American Geophysical Union meeting, so I have access to lots of fossils! This fossil is from the Lower Cretaceous (about 125 million years ago) and was found in what is now Brazil. It is a perfect sample for my favorite game of “animal, vegetable, mineral”—we already know it is a mineral now, but was it once an animal or a vegetable (as in a plant)? Does it help if I tell you that you can find something very similar today?
