Dawkins’s answer to the Edge question: the genome as palimpsest

As I posted yesterday, a lot of contributors gave their answers to the 2017 annual Edge Question, “What scientific term or concept ought to be more widely known?” (See all responses here.) In the last 24 hours Richard Dawkins has weighed in with his answer, “The genetic book of the dead,” which involves reverse-engineering our DNA sequences to reconstruct the ancestral environments of living species. While Dawkins has discussed this before, most notably in Unweaving the Rainbow, not everyone’s read that book. It’s worth considering that an organism’s genome may be a palimpsest of its ancestry, which in turn reflects in part the environments to which those ancestors were adapted.

You can read Richard’s piece for yourself; I’ll give one brief excerpt:

Given a key, you can reconstruct the lock that it fits. Given an animal, you should be able to reconstruct the environments in which its ancestors survived. A knowledgeable zoologist, handed a previously unknown animal, can reconstruct some of the locks that its keys are equipped to open. Many of these are obvious. Webbed feet indicate an aquatic way of life. Camouflaged animals literally carry on their backs a picture of the environments in which their ancestors evaded predation.

But most of the keys that an animal brandishes are not obvious on the surface. Many are buried in cellular chemistry. All of them are, in a sense which is harder to decipher, also buried in the genome. If only we could read the genome in the appropriate way, it would be a kind of negative imprint of ancient worlds, a description of the ancestral environments of the species: the Genetic Book of the Dead.

Naturally the book’s contents will be weighted in favour of recent ancestral environments. The book of a camel’s genome describes recent milennia in deserts. But in there too must be descriptions of Devonian seas from before the mammals’ remote ancestors crawled out on the land. The genetic book of a giant tortoise most vividly portrays the Galapagos island habitat of its recent ancestors; before that the South American mainland where its smaller ancestors thrived. But we know that all modern land tortoises descend earlier from marine turtles, so our Galapagos tortoise’s genetic book will describe somewhat older marine scenes. But those marine ancestral turtles were themselves descended from much older, Triassic, land tortoises.  And, like all tetrapods, those Triassic tortoises themselves were descended from fish. So the genetic book of our Galapagos giant is a bewildering palimpsest of water, overlain by land, overlain by water, overlain by land.

"...This discovery is interesting also because it’s possible that such a thing happened to the ancestors of birds as well which may explain why they have no teeth."

I thought it was because they didn't floss.

Limusaurus inextricabilis was a dinosaur that lost its teeth during its growth

An article published in the journal “Current Biology” describes a research on a dinosaur with characteristics similar to birds called Limusaurus inextricabilis. A team of researchers studied 19 specimens ranging from babies to adults discovered in today’s Xinjiang province in China to analyze how they developed teeth and then lost them over time.

Limusaurus inextricabilis was a very small dinosaur with a length that could reach 170 cm (5′ 7″) and a weight that could reach about 15 kg (33 lbs). They belonged to the ceratosaurs (Ceratosauria) group and, while they were a rather ancient and primitive species, had several characteristics similar to those of birds. Ceratosaurs were theropod dinosaurs, just like those that evolved into birds and in some cases even species that are distantly related may show similar characteristics.

The first specimens of Limusaurus inextricabilis were discovered in 2009, at the time only two subadults. The big step forward arrived with the discovery of 17 more specimens of various ages divided into three groups: six were juveniles, ten were subadults with age estimated between 2 and 6 years and one adult. They lived about 159 million years ago, during the Jurassic period.

The study of the teeth showed the most distinctive feature of Limusaurus inextricabilis because the youngest had small sharp teeth while adults and subadults were completely toothless. These differences made the paleontologists believe they had discovered two species of ceratosaurs, so much so that they started describing them separately. However, in the course of their study, they realized that the specimens showed many similarities except for the teeth and concluded that it was a single species that lost their teeth throughout its life.

This is an unprecedented discovery regarding dinosaurs and in general fossil vertebrates. Today similar changes occur in the platypus and in some species of fish and amphibians. However, these are rare cases so the study of Limusaurus inextricabilis is even more important and suggests that these dinosaurs radically changed their diet from adolescence to adulthood.

The analyzes of the fossils, also at isotopic level, indicate that Limusaurus inextricabilis juveniles were probably carnivores or omnivores while the adults were herbivores. This discovery is interesting also because it’s possible that such a thing happened to the ancestors of birds as well which may explain why they have no teeth.

The Don choses Betsy DeVos as Education secretary.

https://www.washingtonpost.com/local/education/trump-picks-billiona...

"Betsy DeVos is hardly a household name, but the Michigan billionaire and conservative activist has quietly helped change the education landscape in many states, spending millions of dollars in a successful push to expand voucher programs that give families taxpayer dollars to pay for private and religious schools.

Now DeVos is poised to spread her preference for vouchers nationwide. President-elect Donald Trump on Wednesday named her as his nominee for education secretary, a pick that suggests he aims to follow through with campaign promises to expand the movement toward “school choice” — including vouchers and charter schools — in an effort to break up a public education system that he has called “a government-run monopoly.”

Trump’s pick has intensified what already was a polarized debate about school choice. Advocates for such choice see in the Trump administration an extraordinary opportunity to advance their cause on a national scale, whereas teachers unions and many Democrats fear an unprecedented and catastrophic attack on public schools, which they see as one of the nation’s bedrock civic institutions.

[Pence accomplished in Indiana what Trump wants for national education]

Jim DeMint, president of the conservative Heritage Foundation, cheered DeVos on Wednesday, saying that “the school choice movement will have a champion in the Education Department.” American Federation of Teachers President Randi Weingarten said that Trump’s pick “makes it loud and clear that his education policy will focus on privatizing, defunding and destroying public education in America.

As a billionaire Republican power broker with no professional experience in schools, DeVos is an unconventional choice to lead the federal education bureaucracy. And while her views on choice are well known, it is unclear how she would lead a department with responsibilities that sprawl from administering student loans to enforcing civil rights in schools.

She has said little about Common Core, for example, and her ties to organizations that support the K-12 academic standards — including as a board member of the Foundation for Excellence in Education, started by former Florida governor Jeb Bush — raised concern for Trump supporters, who saw her nomination as a sign that the president-elect is wavering on his vehement opposition to the standards.

From her Twitter account Wednesday, DeVos linked to a website where she wrote that she had initially believed in the standards but became disenchanted with them as they “got turned into a federalized boondoggle.”

“I am not a supporter — period,” she wrote.

To wax and wane check out the PewResearch Center Religion & Public Life

Unfortunately non-believers in strict religious areas (usually from fundamentalist Abrahamic land) often don't have the spine, or support to buck creationism off the educational horse -  

The VP Elect Mike Pence from the skittish "Who's There?" State of Indiana along with (I'm cauterizing my and fingers) other Bible Belt States insist that teaching critical thinking undermines parental authority.

Texas Public Schools Are Teaching Creationism

An investigation into charter schools’ dishonest and unconstitutional science, history, and “values” lessons.

Warning. Don't use skulls for evidence of evolution as they were used as scientific proof in the 1920's that 'races' other than Anglo-Saxons were inferior.
