Meanwhile, over in...Azerbaijan?

Apparently, Azerbaijan is experiencing some controversy regarding the age of the earth.  Durna Safarova of writes:
“And it is He who created the heavens and the earth in six days.” Thus read the draft version of a proposed textbook for 10th-grade geography students in Azerbaijan in a section about how the universe was formed. As homework, the book suggested that students prepare presentations on verses from the Koran, referring them to the Azerbaijani-language website

The textbook draft was posted online at the end of March for public comment: it quickly became a hot discussion topic as Azerbaijan wrestles to determine the proper place of religion in public life. In response to the posted draft, a group of parents, scientists, and public figures used social media to organize a campaign against what they described as a government imposition of religious propaganda on their children.
As the story notes, Azerbaijan is almost unique in the region as being a largely secular state, due to years of rule by the Soviet Union.  It is surrounded by Islamic nations, however, and Islam is becoming more commonplace.  This textbook is a reflection of that.  Safarova continues:
“Until now, history books have only presented the theory of evolution,” said Kamran Asadov, the author of the 10th-grade history textbook. “Students should make the choice for themselves about what is correct.”

Others, though, worry about the impact of religion, and especially the growing influence of creationism and other forms of pseudoscience. Azerbaijanis, curious about new ideas after the collapse of the Soviet Union, were favored targets for creationist missionaries from Turkey.
The idea that students should make up the choice for themselves about which is correct is absurd, on its face. It is the kind of thing that is commonplace among young earth creationists, that we have access to the same facts, we just interpret them differently.  This will be a hard thing to fight for the same reason it is hard to fight in the United States: the acceptance of creationism is tied to an acceptance of the one true religion.  People don't tend to think clearly about science if they are driven by this perspective.

Julie Chang: State panel limits teaching phenomena that challenge evolution

As Don McLeroy suggested, I hunted up Julie Chang's article covering the State Board of Education in Texas.  Here is what she writes:
By swapping out a few words in high school biology curriculum standards, the State Board of Education has limited the teaching of scientific phenomena that challenge the theory of evolution, a move that liberals hailed as a victory.

The panel on Friday approved a pared down version of the high school biology curriculum standards after committees of teachers and scholars worked for months to streamline the state’s voluminous science curriculum for all grades. The standards that covered evolution became the most hotly debated issue during the process.

“It was clear from testifiers that many who had varied concerns found the compromise language chosen by the board to be acceptable, addressing both the need to streamline content while still encouraging critical thinking by students,” said board chairwoman Donna Bahorich, R-Houston.
Then comes a particularly problematic paragraph:
Currently, high school students must learn about scientific phenomena that can’t readily be explained by evolution, like cell complexity, origin of DNA and life, and abrupt appearances in fossil records, which left-leaning critics have said invites teachings of creationism and intelligent design.
The origin of DNA and life is not the purview of evolution. Evolution deals with existing biological diversity. The notion that evolution explains the origin of life is consistently brought up by people antagonistic to evolutionary theory, despite this. Second, what abrupt appearances in the fossil record is she writing about? This phrase is often used by people who are unfamiliar with the fossil record.  Transitional fossils are commonplace in the fossil record and, often, “abrupt gaps” turn out to be nothing of the sort. There are certainly periods of time when evolution proceeds more quickly than others, but that is all.

Then there is the snarky remark that critics are “left-leaning.” I am not left-leaning, nor is anyone that I know at BioLogos.  Evolutionary theory is apolitical, as is gravitational theory, cell theory (which Ms. Chang incorrectly argues cannot be explained by evolutionary theory), plate tectonic theory and quantum theory. To argue that critics of some of these statements are “left-leaning” betrays a political bias, rather than a scientific one.

While the rest of the article may accurately portray the changes that were made to the standards, the editor of the Statesman should have flagged that paragraph for removal, since it adds nothing to the story and includes several incorrect statements.

Is Homo floresiensis a Sister Species of Homo habilis?

A short blurb in Science Magazine attempts to lay to rest one of the nagging questions in recent human evolution: where did the diminutive “hobbits” originate?  A report by the Australian National University suggests that Homo floresiensis is a sister species of Homo habilis
Data from the study concluded there was no evidence for the popular theory that Homo floresiensis evolved from the much larger Homo erectus, the only other early hominid known to have lived in the region with fossils discovered on the Indonesian mainland of Java.

Study leader Dr Debbie Argue of the ANU School of Archaeology & Anthropology, said the results should help put to rest a debate that has been hotly contested ever since Homo floresiensis was discovered.

"The analyses show that on the family tree, Homo floresiensis was likely a sister species of Homo habilis. It means these two shared a common ancestor," Dr Argue said.

"It's possible that Homo floresiensis evolved in Africa and migrated, or the common ancestor moved from Africa then evolved into Homo floresiensis somewhere."

Homo floresiensis is known to have lived on Flores until as recently as 54,000 years ago.
How do we know this?
Where previous research had focused mostly on the skull and lower jaw, this study used 133 data points ranging across the skull, jaws, teeth, arms, legs and shoulders.

Dr Argue said none of the data supported the theory that Homo floresiensis evolved from Homo erectus.
I think that it is passing peculiar that we have found absolutely nothing else like this in over 100 years of searching in this area, but who knows what these smaller islands have hidden in them. This also raises interesting questions. Since we know that early Homo got as far as Russian Georgia, is it possible they got as far as Flores? That's a long way.  Is it possible that incoming Homo erectus out-competed them in most places except for a few small refugia?  Also possible.   Hopefully more information will turn up to help us answer these questions.

Slightly Off-Topic: The March for Science

The Christian Science Monitor wonders aloud if science and political activism can co-exist.  Amanda Paulson writes:
The foray into activism and politics is a tough one for some scientists. And although the organizers have taken pains to note the march is nonpartisan, concern that the focus will become political has sparked some controversy and debate among scientists.

Many supporters of the march note that science is already political, and that ignoring its importance to policy is disingenuous. The march is needed, they say, due to the increased attacks on science, threats to slash funding for research, and lack of understanding of what scientists do.

But critics worry that despite all the declarations that the march is “non-partisan,” it will be viewed by many Americans as anti-Trump and anti-Republican, and that it will only increase the partisan divide and cement the impression in some people’s minds that scientists are driven by ideology rather than evidence.

“I worry there will be people there carrying signs that have incendiary messages, and it’s that one percent that will become the meme for the conservative blogosphere,” says Robert Young, a coastal geologist at Western Carolina University. He cringes imagining rural America’s reaction to, say, a sign saying “Make America smart again.”
One of the things that I have anecdotally noticed in the thirty some years that I have been associated with science in one way, shape or form, is that people have a tendency to develop their socio-cultural viewpoints irrespective of the science that they practice. For example, I have never seen science turn a Christian into an atheist, or vice versa.  Richard Dawkins once wrote that evolution allowed him to “ an intellectually fulfilled atheist.”  In other words, he was already an atheist.  He was just now using evolution as a cover to justify it.  Given that I know other people that view evolution as displaying the glory of God, the argument that one is tied to the other is somewhat suspect.

One thing is certain: there are already quite a few people out there that have watched the democratic party and its associated left-leaning groups implode after the election and thought to themselves “Good thing I voted for Trump.” The very same thing could happen here if the March for Science is hijacked by leftist groups. It could very well result in Trump and his advisors thinking that, why yes, it would be perfectly appropriate to start cutting these budgets.

The organizers have a golden moment on their hands.  If they can show the world that the scientific endeavor is benefiting all of humanity in noticeable, tangible ways, then it will have done its job.  If it descends into Trump-bashing and elitism, then expect that the general public's support for science, which is already at an all-time low, will continue to erode and, yes, expect budgetary cuts.

Texas State Board of Education In the Crosshairs Again

The Texas State Board of Education is revising standards for science again, in response to criticisms that they allow for the teaching of creationism.  Andrea Zelinski, of the Houston Chronicle, writes:
The Texas State Board of Education on Wednesday took a preliminary vote to compromise on a pair of high-school science standards that critics say encouraged the teaching of creationism.

The 15-member board voted unanimously to change language in its standards to take the pressure off teachers to delve deep in evaluating cell biology and DNA evolution.

"I was very pleased with how smoothly everything went," said Ron Wetherington, an evolutionary anthropologist at Southern Methodist University and member of the High School Biology Streamlining Committee that recommended the board modify language in the standards to save teachers class time.

Standards using words like "analyze and evaluate" are like "dogs whistles," he said, that ideological groups see as an opening to explore creationism and intelligent design as explanations for the origin of life.

The first change to the standards, if confirmed by a second vote on Friday, would require students to "compare and contrast scientific explanations" for the complexity of cells, instead of "evaluate." The change would return the standard to the original language recommended by the committee, reversing an addition in February authored by Republican board member Barbara Cargill of The Woodlands.
As the article points out, Texas has had a long and heated battle with creationists on the board, led by Cargill and Don McLeroy, continually watering down the standards.  Hopefully, things will look up for students of science in Texas.

Off Topic: Freeze Frame!

It seems that we are having a hard time getting our aging rockers to live past the age of 71.  The latest casualty is J. Geils, who's band had some pretty large hits in the 1980s.  From Boston's WCVB TV:
"A preliminary investigation indicates that Geils died of natural causes," police said in a statement.

The J. Geils Band was founded in 1967 in Worcester, Massachusetts, while Geils, whose full name was John Warren Geils Jr., was studying mechanical engineering at Worcester Polytechnic Institute. Geils served as the band's guitarist and vocalist. Bandmates included Danny Klein, Richard "Magic Dick" Salwitz, Stephen Jo Bladd, Peter Wolf and Seth Justman.

The band, whose music blended blues rock, R&B, soul and pop, released 11 studio albums and built a large following due to their energetic live shows as well as their unusual use of the harmonica as a lead instrument. The band broke up in 1985, but reunited off and on over the years.
I never, honestly, listened to much J.Geils Band music, not being that much of a fan of stripped-down rock, but it was hard not to like the tongue-in-cheek aspect of many of the songs, including “Love Stinks” and “Centerfold.”


And, of course, the obligatory...

Creationism in Ireland and "Alternative Facts"

I am not sure how this term “alternative facts” managed to become common parlance. The Irish news is reporting on a traveling roadshow that is trying to educate young kids that dinosaurs and humans coexisted (as Barry Lynn notes: "only on the Flintstones").  Paul Ainsworth writes:
AN organisation is to tour Ireland with an event teaching children that dinosaurs and humans existed on Earth at the same time.

The ‘Prehistoric Preachers Dinosaur Roadshow’ is hosted by Creation Ministries, which promotes the belief that the world is only around 6,000 years old.

The fundamentalist Christian organisation says the roadshow - to visit four venues across the north during May before moving to five locations in the Republic – will teach the “true history of the world to young and old alike”.

Children are offered the chance to sit on life-size replicas of dinosaurs and take home an “educational free gift”.

However, it has been warned that the message that dinosaurs did not die out 65 million years ago flies in the face of conventional understanding of natural history, with one critic dubbing the claims put forward by organisers as “dangerous alternative facts”.
There are no such things as “alternative” facts.  There are scientific observations about observable phenomena that generate hypotheses.  If several thousand of these hypotheses support a particular model, then a theory explaining the phenomenon is generated.  That is how we have gravitational theory, cell theory, plate tectonic theory and, yes, evolutionary theory.

Facts are instances in which so many concurrent observations have been made that support a particular understanding of some natural phenomenon that it is regarded as a near certainty.  Everyone on the planet agrees that marble is a rock.  No one has ever observed marble behaving in such a way that makes one suspect that it is not.  Therefore, it is a FACT that marble is a rock.

Theoretical constructs, on the other hand, are open to examination and change.  Young earth creationism is a theory that the earth was created six thousand years ago and that modern science supports this.  That can be critically examined.  When it is, however, it is found that no hypotheses that are constructed to test this theory have been found that DO support it.  Put simply, the theory has no empirical justification.  Further, it is found that the primary advocates of this theory put it forth from a religious and not a scientific perspective.

But you knew this.

The problem is in calling these“alternative facts.” They are not. They are scientifically unsupportable statements made about observable phenomena and that is what they need to be called.

Arkansas Creationism Bill DOA

In a short note, NCSE is reporting that the Arkansas bill authorizing the teaching of creationism and ID alongside evolution never made it to a vote:
When the Arkansas legislature recessed on April 3, 2017, House Bill 2050 (PDF)— which would, if enacted, have allowed "public schools to teach creationism and intelligent design as theories alongside the theory of evolution" — apparently died.

Introduced on March 6, 2017, by Mary Bentley (R-District 73), HB 2050 was filed as a shell bill, with only its title, subtitle, and a description of its purpose provided. Bentley apparently never provided the text of her bill to the legislature.
And there was much rejoicing.
