In part 1, I looked at the phenomenon of the Great Unconformity, a gap between Grand Canyon layers that spans more than a quarter of Earth’s history. Though geologists understand how unconformities like this occur, creationists have a rather different view about what formed the Great Unconformity.

Steve Austin, the dean of Grand Canyon creationist geologists, writes in the book Grand Canyon: Monument to Catastrophe:

In part 1, I was discussing a passage attributed to Charles Lyell by Luther Tracy Townsend, whose Collapse of Evolution (1905), as Ronald L. Numbers notes in The Creationists (1992), “assembled one of the earliest—and most frequently cribbed—lists in order to prove that ‘the most thorough scholars, the world’s ablest philosophers and scientists, with few exceptions, are not supporters, but assailants of evolution.’” According to Townsend, Lyell wrote, “In the year 1806 the French Institute enumerated not less than eighty geological theories which were hostile to the Scriptures; but not one of those theories is held to-day.” The passage appears not anywhere in Lyell’s work, however, but instead (more or less) in Albert Barnes’s The Progress and Tendencies of Science (1840). So how did Townsend form the idea that it was from Lyell?

On Friday, I was happy to report that climate change denial was removed from the social studies textbook Pearson proposed to sell in Texas. And I was sad to say that McGraw-Hill hadn’t gone far enough in addressing climate change denial in their Texas geography textbook. I’m pleased to be able to update that report and say that both publishers have now agreed to correct their coverage of climate change.

Last week on Fossil Friday, we departed our Nevada-centric fossilizing to head east to Kentucky. Fossil Fan Dan Phelps brought us this lovely fossil, from the Strodes Creek Formation, hailing from the Upper Ordovician. What was it? Why, a bryozoan, of course, and Dan suspects it was Constellaria florida. Congratulations to Dan Coleman, who nailed the genus.

When Presidents Obama and Xi met for dinner recently to discuss the new climate change agreement between their two nations, the Chinese president used the metaphor “a pool begins with many drops of water” to describe the potential for the two nations to collaborate in substantially reducing greenhouse gas emissions.

The latest battle over Texas textbooks is coming to a head. Next week, the state board of education will vote to adopt social studies textbooks, setting the list of books approved for use in history, geography, social studies, economics, and other classes for next decade. Normally we at NCSE don’t spend much time looking at social studies textbooks, but climate change comes up in several of the books and we looked them over to make sure the science was right.

I realize that most of my Fossil Fridays lately have been a little focused on the West—in fact Nevada in particular seems to keep coming up a lot lately. No, it’s not because I’m planning a trip to Las Vegas this winter—I just got trapped in the Nevada section of the archives recently and the only way out was to photograph everything I could find there. I’m sure this happens to you all the time!

For anyone with a taste for the history of creationist shenanigans with scientific literature, Luther Tracy Townsend’s Collapse of Evolution (1905) is the gift that keeps giving. As Ronald L. Numbers notes in The Creationists (1992), in his book Townsend “assembled one of the earliest—and most frequently cribbed—lists in order to prove that ‘the most thorough scholars, the world’s ablest philosophers and scientists, with few exceptions, are not supporters, but assailants of evolution.’” As a result, whenever I start to investigate a quotation from or a citation of a scientist of a particular vintage, I’m not surprised to find that Townsend is the fons et origo. And here, from my recent cover-to-cover reading of Collapse of Evolution (which also inspired “A ‘Puerile Hypothesis’?” on a Townsendian misrepresentation of St. George Mivart), is a doozy.

I’ve written before about Mimi Shirasu-Hiza, she of the twice-demonstrated ability to see the seeds of discovery in what might easily be dismissed as messy data. How did this scientist, who is unraveling the ways that fruit flies’ ability to fight off infections is affected by such variables as the time of day and the state of their intestinal microbes, find her way to the laboratory bench? When I told Mimi about NCSE’s efforts to highlight the importance of high school teachers, she volunteered her own story.

I spent the first few hours today in an uncanny glow. On opposite sides of the planet, in utterly different realms, scientists and political leaders had, in two very different ways, accomplished the unthinkable.

The first instance actually hit just before I went to bed. News broke late yesterday that President Obama and Chinese President Xi Jinping had come to a binational agreement on targets for climate pollution reduction. Scratch that; it sounds too dull for what it means.
