Creationism, Noah’s Flood, and Race

20^th-Century creationism and racism

Henry Morris, CRI publicity photo

(re-post from 3 Quarks Daily): Henry Morris, founding father of modern Young Earth creationism, wrote in 1977 that the Hamitic races (including red, yellow, and black) were destined by their nature to be servants to the descendants of Shem and Japheth. Noah was inspired when he prophesied this (Genesis 9:25-27) [1]. The descendants of Shem are characterised by an inherited religious zeal, those of Japheth by mental acumen, while those of Ham are limited by the “peculiarly concrete and materialistic thought-structure inherent in Hamitic peoples,” which even affects their language structures. These innate differences explain the success of the European and Middle Eastern empires, as well as African servitude.

All this is spelt out in Morris’s 1977 book, The Beginning of the World, most recently reprinted in 2005 (in Morris’s lifetime, and presumably with his approval), and available from Amazon as a paperback or on Kindle.

Morris is no fringe figure. On the contrary, he, more than any other individual, was responsible for the 20^th-century invention of Young Earth “creation science”. He was co-author of The Genesis Flood, which regards Noah’s flood as responsible for sediments worldwide, and founded the Institute of Creation Research (of which Answers in Genesis is a later offshoot) in 1972, serving as its President, and then President Emeritus, until his death in 2006.

Relevant again; Why Michael Gove is not fit to lead anything

Gove claiming that EU regulations prevent us from keeping out terrorists. Dylan Martinez via Daily Telegraph

“People in this country have had enough of experts,” said Michael Gove. The experts who tell us that Brexit will be damaging and a no-deal Brexit devastating; that human-caused global warming is a clear and present danger [Correction: Michael Gove does accept the expert consensus on climate change]; that physics teachers know more about physics (and about teaching) than Michael Gove did when telling them what and how to teach and getting it wrong from beginning to end; that actions have consequences; that reality matters.

And so, regretfully, for the third time, why Michael Gove is not fit to lead an Easter egg hunt, let alone a nation on the brink of the most catastrophic decision since 1914.

And since among other things that decision may well force us to submit to whatever trading arrangements the Tramp Administration chooses to impose on us, I would also draw attention to Miles King’s Michael Gove and the American Neoconservatives.

Anyway,here we go again:

Thermodynamics: turbines

The [then] Education Secretary said “What [students] need is a rooting in the basic scientific principles, Newton’s laws of thermodynamics and Boyle’s law.” [reported here]. He has been widely criticized for this (e.g. here and here), but it’s still worth discussing exactly why what he said is so appallingly wrong, on at least four separate counts. In the unlikely event that Mr. Gove ever reads this, he may learn something. Muddling up the laws of motion with the laws of thermodynamics is bad enough. Muddling up an almost incidental observation, like Boyle’s Law, is even worse, especially when this muddle comes from someone in charge of our educational system [well, not mine actually; I’m glad to say I live in Scotland], and in the very act of his telling teachers and examiners what is, and what is not, important.

Newton’s Laws: sailing ships

Okay, from the top. Newton’s laws; Gove probably meant (if he meant anything) Newton’s laws of motion, but he may also have been thinking of Newton’s law (note singular) of gravity. [I went on to summarise both Newton’s laws, and Newton’s law, and to explain how the combination of these explained the hitherto mysterious phenomenon of planetary motion and related it to the motion of falling bodies on Earth; an intellectual achievement not equalled until Einstein’s General Theory of Relativity]

But what about the laws of thermodynamics? These weren’t discovered until the 19^th century, the century of the steam engine… [I briefly described them]

If you don’t immediately realize that Newton’s laws and the laws of thermodynamics belong to different stages of technology, the age of sail as opposed to the age of steam, and to different levels of scientific understanding, the individual and macroscopic as opposed to the statistical and submicroscopic, then you don’t know what you’re talking about. Gove’s blunder has been compared to confusing Shakespeare with Dickens. It is far, far worse than that. It is – I am at a loss for an adequate simile. All I can say is that it is as bad as confusing Newton’s laws with the laws of thermodynamics, and I can’t say worse than that.

And regarding Gove’s description of Boyle’s Law as “basic”, I had this to say:

He [Gove] has been justly mocked for confusing Newton’s laws with the laws of thermodynamics. But the kind of ignorance involved in describing Boyle’s Law as a “basic scientific principle” is far more damaging.

Disclosure: I taught Boyle’s Law for over 40 years, and it gets three index entries in my book, From Stars to Stalagmites.

Bottom line: Boyle’s Law is not basic. It is a secondary consequence of the kinetic theory of gases, which is basic. The difference is enormous, and matters. Anyone who thinks that Boyle’s Law is a principle doesn’t know what a principle is. (So Gove doesn’t know what a principle is? That figures.)

Mathematically, the Law is simply stated, which may be why Mr Gove thinks it is basic: volume is inversely proportional to pressure, which gives you a nice simple equation (P x V = a constant) that even a Cabinet Minister can understand. But on its own, it is of no educational value whatsoever. It only acquires value if you put it in its context [in the kinetic theory of gases], but this involves a concept of education that seems to be beyond his understanding…

Educationally, context is everything, the key to understanding and to making that understanding worthwhile. A person who decries the study of context is unfit for involvement with education.

Even at Cabinet level.

And, I would now add, completely unfit for making major decisions in these interesting times.

Evolution goes viral! (And how real science works)

I have just one good thing to say about Behe’s book: the rebuttals have introduced me to some splendid science, such as this: a four-mutation sequence with enhanced function at each step, refuting all three of Behe’s arguments; and reproducible!

Telliamed Revisited

This is the fourth in a series of posts about a new book by Michael Behe, Darwin Devolves. Behe is a leading proponent of intelligent-design creationism (IDC), which asserts that known processes cannot adequately account for evolution and, therefore, some intelligent agent must be involved in the process. Behe is a professor of biochemistry, which gives him knowledge and credentials that most IDC advocates do not have. However, my posts explain why I think his logic is unsound and his evidence weak and biased.

In brief, Behe argues that random mutation and natural selection are almost entirely degradative forces that break or blunt the various functions encoded by genes, producing short-term advantages that are so pervasive that they prevent constructive adaptations, which he claims are very unlikely to emerge in the way that evolutionary biologists have proposed. Unlike young-Earth creationists, Behe accepts the descent of living species from common…

Darwin does devolve. Sometimes. So what?

“[T]here is in fact nothing that can alleviate that fatal flaw in Darwinism” says Professor Behe, stating the book’s central claim in the mendaciously mislabelled creationist web journal Evolution News.

The claim is clickbait, the book title misleading, and the argument long since rebutted. The historical roots of the argument show the close links between what now calls itself Intelligent Design, and biblically inspired “creation science”. The issues are important because the Intelligent Design movement gives a veneer of intellectual respectability to the denial of scientific reality.

Can we trust radiocarbon dating? Update; full paper available

Primate's Progress

Willard Frank Libby, inventor of the method

Can we trust radiocarbon dating? Young Earth creationists tell us that we can’t. After all, it makes the same range of assumptions as other radiometric dating methods, and then some. Other methods benefit from internal checks or duplications, which in the case of radiocarbon dating are generally absent. There are numerous cases where it appears to give absurdly old ages for young material, while apparent ages of a few tens of thousands of years are regularly reported for material known on other evidence to be millions of years old. So can the Young Earth creationist¹ objections be rebutted, and if so how?

The principle of radiometric dating is simple.² If we know how much of a particular radioactive substance was present when a material formed, how much is still there, and

The Roots of Creationism

Never forget that the claim of today’s Young Earth creationists to be following the Bible is simply untrue. The fantastical convulsions, supposedly occurring at the time of the Flood, that they invoke to explain the facts of geology are not at all biblical, but derived from the visions of Ellen White, founder-prophetess of Seventh-day Adventism. In this post, my friend Michael Roberts, geologist and priest, gives us a sample of the extensive scholarship in which he sets the record straight.

Peddling and Scaling God and Darwin

Where did Creationism come from?

Creationism still confuses many people. So often it is seen as a throw-back to the time when people were not so enlightened or intelligent and under the sway of church dogma.

It is amazing some still hold that and fail to recognise the scientific skills of those in the Middle Ages – most notably Christians and clergy like Bacon, Grossteste among others.

We may despair, as I do of those like Ken Ham, Henry Morris and others, who try to prove the earth is only 6000-10,000 years old and we may be tempted to pour scorn as this cartoon does.

However we should assume that this crazy ideas were the views of Christians in previous centuries and so much of the work of scholars like John Hedley Brook, David Livingstone and Ron Numbers among many others have demonstrated this time and time again in the…

Teaching evolution in Kentucky, 2: The Case of the Ivory-billed Woodpecker

The thing about teaching is we are never sure we are making a difference.

Jim Krupa takes evolution as his central theme when he teaches biology to non-majors at the University of Kentucky, where the students are most unlikely to have heard about evolution in school, but may well have been warned about its wickedness in church. With his permission, I am posting an article that he wrote in Orion Magazine describing his experiences. The first part dealt with the challenges he faces. This second part describes his response, which centres on a discussion of the nature of scientific reasoning, followed by the case study (described in greater detail[1]in’s American Biology Teacher), and concludes with a discussion of outcomes. Notice how many misconceptions Jim demolishes on the way, including confusion about the  role of theory in science, the curious but widespread belief that evolution science is without practical application, and (particularly important in his local context) the claim that accepting evolution is incompatible with religion.

Jim teaches, and touches the lives of, 1800 students a year – enough, over time, to flip a good few school districts and make a real difference to the cultural climate of the State. And we can be sure that his students will have plenty to talk about with their friends.

Defending Darwin (continued)

By James Krupa

The (now-extinct) Ivory-build Woodpecker, central to Prof Krupa’s case study

ONCE I LAY DOWN the basics of science, I introduce the Darwinian theories of evolution. Charles Darwin was by no means the first or only to put forth evolution; others came before him including his grandfather, Erasmus Darwin, who wrote about descent with modification. Later, while Charles was amassing evidence in England for natural selection, one of the most eloquent scientific theories ever, Alfred Russel Wallace was also developing the same theory during his travels in Indonesia. But it was Charles Darwin alone who advanced the theory of descent with modification, with his bold idea that all species belong to the same tree of life and thus share a common ancestor. He also gave us sexual selection theory, which explains how evolution is shaped by competition for mates as well as choice of mates. Too often only natural selection and descent with modification are emphasized in introductory biology classes. I also cover Darwin’s theories of gradualism (including the nuance of punctuated equilibrium); descent from a common ancestor; multiplication of species; and sexual selection. I emphasize that five of the theories explain the patterns of evolution, while natural and sexual selection are the mechanisms that drive evolution.

Teaching evolution to creationists in Kentucky (by one who does it for a living)

Evolution and scientific logic lie at the heart of Prof Jim Krupa’s award-winning biology course at the University of Kentucky, conveyed by a mixture of story-telling, the Socratic method, and student engagement in a case study close to his heart as a naturalist. Jim has kindly agreed to let me post his article in Orion Magazine. The first part (here) describes the  hostile cultural environment in which he is working, why evolution is at the core of his teaching, and how he begins his course by clearing away semantic nonsense, and analysing the concept of scientific theory.

You will find more detail about this in one of his articles in The American Biology Teacher [1]. Jim uses the National Academies definition of a scientific theory as well-attested by observation, but, as he explains there, he is well aware of its limitations, and  anatomises “the” theory of evolution into its separate independent components, before bringing them to bear on the case study that I will be describing the second part of this two-part series.

Defending Darwin

By James Krupa

I’M OFTEN ASKED what I do for a living. My answer, that I am a professor at the University of Kentucky, inevitably prompts a second question: “What do you teach?” Responding to such a question should be easy and invite polite conversation, but I usually brace for a negative reaction. At least half the time the person flinches with disapproval when I answer “evolution,” and often the conversation simply terminates once the “e-word” has been spoken. Occasionally, someone will retort: “But there is no evidence for evolution.” Or insist: “It’s just a theory, so why teach it?”

At this point I should walk away, but the educator in me can’t. I generally take the bait, explaining that evolution is an established fact and the foundation of all biology. If in a feisty mood, I’ll leave them with this caution: the fewer who understand evolution, the more who will die. Sometimes, when a person is still keen to prove me wrong, I’m more than happy to share with him an avalanche of evidence demonstrating I’m not.

Some colleagues ask why I bother, as if I’m the one who’s the provocateur. I remind them that evolution is the foundation of our science, and we simply can’t shy away from explaining it. We don’t avoid using the “g-word” when talking about gravitational theory, nor do we avoid the “c-word” when talking about cell theory. So why avoid talking about evolution, let alone defending it? After all, as a biologist, the mission of advancing evolution education is the most important aspect of my job.

an institution steeped in the history of defending evolution education

TO TEACH EVOLUTION at the University of Kentucky is to teach at an institution steeped in the history of defending evolution education. The first effort to pass an anti-evolution law (led by William Jennings Bryan) happened in Kentucky in 1921. It proposed making the teaching of evolution illegal. The university’s president at that time, Frank McVey, saw this bill as a threat to academic freedom. Three faculty members—William Funkhouser, a zoologist; Arthur Miller, a geologist who taught evolution; and Glanville Terrell, a philosopher—joined McVey in the battle to prevent the bill from becoming law. They put their jobs on the line. Through their efforts, the anti-evolution bill was defeated by a forty-two to forty-one vote in the state legislature. Consequently, the movement turned its attention toward Tennessee.

The Funkhouser building. Funkhouser, then Professor of Zoology, was among those who successfully campaigned against a 1921 State bill that wold have made the teaching of evolution illegal.

John Thomas Scopes was a student at the University of Kentucky then and watched the efforts of his three favorite teachers and President McVey. The reason the “Scopes Monkey Trial” occurred several years later in Dayton, Tennessee—where Scopes was a substitute teacher and volunteered to be prosecuted—was in good part due to the influence of his mentors, particularly Funkhouser. As Scopes writes in his memoir, Center of the Storm: “Teachers rather than subject matter rekindled my interest in science. Dr. Funkhouser . . . was a man without airs [who] taught zoology so flawlessly that there was no need to cram for the final examination; at the end of the term there was a thorough, fundamental grasp of the subject in bold relief in the student’s mind, where Funkhouser had left it.”

I was originally reluctant to take my job at the university when offered it twenty years ago. It required teaching three sections of non-majors biology classes, with three hundred students per section, and as many as eighteen hundred students each year. I wasn’t particularly keen on lecturing to an auditorium of students whose interest in biology was questionable given that the class was a freshman requirement.

Then I heard an interview with the renowned evolutionary biologist E. O. Wilson in which he addressed why, as a senior professor—and one of the most famous biologists in the world—he continued to teach non-majors biology at Harvard. Wilson explained that non-majors biology is the most important science class that one could teach. He felt many of the future leaders of this nation would take the class, and that this was the last chance to convey to them an appreciation for biology and science. Moved by Wilson’s words, and with the knowledge that William Funkhouser once held the job I was now contemplating, I accepted the position. The need to do well was unnerving, however, considering that if I failed as a teacher, a future Scopes might leave my class uninspired.

I quickly came to the conclusion that, since evolution is the foundation upon which all biology rests, it should be taught at the beginning of a course, and as a recurring theme throughout the semester.

I realized early on that many instructors teach introductory biology classes incorrectly. Too often evolution is the last section to be taught, an autonomous unit at the end of the semester. I quickly came to the conclusion that, since evolution is the foundation upon which all biology rests, it should be taught at the beginning of a course, and as a recurring theme throughout the semester. As the renowned geneticist Theodosius Dobzhansky said: “Nothing in biology makes sense except in the light of evolution.” In other words, how else can we explain why the DNA of chimps and humans is nearly 99 percent identical, and that the blood and muscle proteins of chimps and humans are nearly identical as well? Why are these same proteins slightly less similar to gorillas and orangu­tans, while much less similar to goldfish? Only evolution can shed light on these questions: we humans are great apes; we and the other great apes (gibbons, chimps, gorillas, bonobos, and orangutans) all evolved from a common ancestor.

Soon, every topic and lecture in my class was built on an evolutionary foundation and explained from an evolutionary perspective. My basic biology for non-majors became evolution for non-majors. It didn’t take long before I started to hear from a vocal minority of students who strongly objected: “I am very offended by your lectures on evolution! Those who believe in creation are not ignorant of science! You had no right to try and force evolution on us. Your job was to teach it as a theory and not as a fact that all smart people believe in!!” And: “Evolution is not a proven fact. It should not be taught as if it is. It cannot be observed in any quantitative form and, therefore, isn’t really science.”

We live in a nation where public acceptance of evolution is the second lowest of thirty-four developed countries, just ahead of Turkey. Roughly half of Americans reject some aspect of evolution, believe the earth is less than ten thousand years old, and that humans coexisted with dinosaurs. Where I live, many believe evolution to be synonymous with atheism, and there are those who strongly feel I am teaching heresy to thousands of students. A local pastor, whom I’ve never met, wrote an article in The University Christian complaining that, not only was I teaching evolution and ignoring creationism, I was teaching it as a non-Christian, alternative religion.

There are students who enroll in my courses and already accept evolution. Although not yet particularly knowledgeable on the subject, they are eager to learn more. Then there are the students whose minds are already sealed shut to the possibility that evolution exists, but need to take my class to fulfill a college requirement. And then there are the students who have no opinion one way or the other but are open-minded. These are the students I most hope to reach by presenting them with convincing and overwhelming evidence without offending or alienating them.

a question I’ve heard many times: “If we evolved from monkeys, why are there still monkeys?”

Some students take offense very easily. During one lecture, a student asked a question I’ve heard many times: “If we evolved from monkeys, why are there still monkeys?” My response was and is always the same: we didn’t evolve from monkeys. Humans and monkeys evolved from a common ancestor. One ancestral population evolved in one direction toward modern-day monkeys, while another evolved toward humans. The explanation clicked for most students, but not all, so I tried another. I asked the students to consider this: Catholics are the oldest Christian denomination, and so if Protestants evolved from Catholics, why are there still Catholics? Some students laughed, some found it a clarifying example, and others were clearly offended. Two days later, a student walked down to the lectern after class and informed me that I was wrong about Catholics. He said Baptists were the first Christians and that this is clearly explained in the Bible. His mother told him so. I asked where this was explained in the Bible. He glared at me and said, “John the Baptist, duh!” and then walked away.

a biology colleague asked … if I would be teaching evolution as a theory or a fact.

To truly understand evolution, you must first understand science. Unfortunately, one of the most misused words today is also one of the most important to science: theory. Many incorrectly see theory as the opposite of fact. The National Academy of Sciences provides concise definitions of these critical words: A fact is a scientific explanation that has been tested and confirmed so many times that there is no longer a compelling reason to keep testing it; a theory is a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence generating testable and falsifiable predictions.

In science, something can be both theory and fact. We know the existence of pathogens is a fact; germ theory provides testable explanations concerning the nature of disease. We know the existence of cells is a fact, and that cell theory provides testable explanations of how cells function. Similarly, we know evolution is a fact, and that evolutionary theories explain biological patterns and mechanisms. The late Stephen Jay Gould said it best: “Evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world’s data. Theories are structures of ideas that explain and interpret facts.”

Theory is the most powerful and important tool science has, but nonscientists have perverted and diluted the word to mean a hunch, notion, or idea. Thus, all too many people interpret the phrase “evolutionary theory” to mean “evolutionary hunch.”

Not surprisingly, I spend the first week of class differentiating theory from fact, as well as defining other critical terms. But I’m appalled by some of my colleagues who, despite being scientists, do not understand the meaning of theory. As I was preparing to teach a sophomore evolution class a few years ago, a biology colleague asked how I was going to approach teaching evolution. Specifically, he asked if I would be teaching evolution as a theory or a fact. “I will teach evolution as both theory and fact,” I said, trying hard to conceal my frustration. No matter. My colleague simply walked away, likely questioning my competence to teach the class.

Hear a conversation with James J. Krupa about his experience teaching evolution.

Shaping of Landscape: A primer on weathering and erosion

Landscape as process, beautifully illustrated. Students with Marli Miller as instructor are fortunate indeed

geologictimepics

Most of us love landscapes –and many of us find ourselves wondering how they came to look the way they do. In most cases, landscapes take their shape through the combined processes of weathering and erosion. While weathering and erosion constitute entire fields of study unto themselves, this primer outlines some of the basics—which pretty much underlie all the further details of how natural processes shape landscapes.

Aerial view of incised meanders of Green River, Utah.

Two definitions: weathering describes the in-place breakdown of rock material whereas erosion is the removal of that material. Basically, weathering turns solid rock into crud while erosion allows that crud to move away.

Weathering
Weathering processes fall into two categories: physical and chemical.  Physical weathering consists of the actual breakage of rock; any process that promotes breakage, be it enlargement of cracks, splitting, spalling, or fracturing, is a type of physical weathering.  Common examples…

Behe demolishes Darwin (yet again!)

Michael Behe has a new book coming out, Darwin Devolves, which according to the mendaciously mislabelled Evolution News “Topples Foundational Claim of Evolutionary Theory.” I am unlikely to be sent a review copy, so I am relying on the Evolution News summary.

In brief, Behe continues to assert the existence of irreducible complexity in animal organs, while maintaining that

Darwinian evolution proceeds mainly by damaging or breaking genes, which, counter-intuitively, sometimes helps survival. In other words, the mechanism is powerfully de-volutionary. It promotes the rapid loss of genetic information.

and encapsulates this conclusion in what he calls the First Rule of Adaptive Evolution:

Break or blunt any gene whose loss would increase the number of offspring.

I reviewed Behe’s earlier statement of this Rule some years ago, in PandasThumb, and friends have suggested that I repost it. So here it is. (I am proud to say that it has already been reposted by Peaceful Science.

Since this First Rule of Adaptive Evolution, the pinnacle of Behe’s argument, was already spelt out in the earlier work, there is little that I need add to my original review below, beyond pointing out that even this puny statement of the obvious came with a debilitating disclaimer

It is called a “rule” in the sense of being a rule of thumb. It is a heuristic, useful generalization, rather than a strict law; other circumstances being equal, this is what is usually to be expected in adaptive evolution

and reminding Behe that he is himself the product of a massive increase in genetic complexity, the doubling and redoubling of the genome that separates him from his early notochord ancestors.  The original review follows [note: in that review I referred to “E.Coli acquiring the ability to metabolise citrate under anaerobic conditions”; that should be “aerobic conditions, in the absence of a reducing agent”. h/t Monica Lewis. this does not, however, affect the logic of the argument]:

Behe’s review in context, or what’s the point?
