Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]

Who do you mean by we?

Sapiens: A Brief History of Humankind by Yuval Noah Harari - "The book delivers on its madly ambitious subtitle by in fact managing to cover key moments in the developmental history of humankind from the emergence of Homo Sapiens to today's developments in genetic engineering." Also btw, check out Harari on the myths we need to survive, re: fact/value distinctions and their interrelationships.

What is thy name?

"Humans as Superorganisms: How Microbes, Viruses, Imprinted Genes and Other Selfish Entities Shape Our Behavior" by Peter Kramer and Paola Bressan discusses the idea that an individual homo sapiens is only one component of the human superorganism we call a person, focusing on the psychological and psychiatric ramifications thereof. (Paola Bressan previously.)

Evolution Lab

"What could you possibly have in common with a mushroom, or a dinosaur, or even a bacterium? More than you might think. In this Lab, you’ll puzzle out the evolutionary relationships linking together a spectacular array of species. Explore the tree of life and get a front row seat to what some have called the greatest show on Earth. That show is evolution." Evolution Lab is a educational game created by the Life on Earth Project and NOVA Labs

Revisiting the Spandrels of San Marco: an interview

The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the Adaptationist Programme” was written by Harvard biologists Stephen Jay Gould and Richard C. Lewontin and published in the Proceedings of the Royal Society of London in 1979. Their critique of their own field of evolutionary biology spilled out of the Ivory Tower onto the pages of general intellectual forums such as the New York Review of Books. I talked by phone with Lewontin on March 2 2015. In his mid-eighties, he is still scientifically active and could recall his collaboration with Gould in detail. Our conversation is highly relevant to the “Just so story” critique that is frequently leveled against Evolutionary Psychology.

Charging toward an era of genetically modified humans

The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]

Defending Darwin

I’m occasionally told my life would be easier if I backed off from my relentless efforts to advance evolution education. Maybe so. But to shy away from emphasizing evolutionary biology is to fail as a biology teacher. I continue to teach biology as I do, because biology makes sense only in the light of evolution.

Let's go sunning / It's so good for you

Leafy, verdant Elysia chlorotica (the Eastern Emerald Elysia) is a sea slug with a secret: they photosynthesize. These marauding mollusks slurp up chloroplasts from their favorite algal snack, Vaucheria litorea, incorporating them into their own digestive cells and putting them to work soaking up sunshine (and, incidentally, acquiring a healthy green glow). But how? [more inside]

I also check my skeletons twice. You can never be too careful.

I waited silently for her to explain that the female pelvis is shaped slightly differently from the male’s, with a larger opening for childbearing. That part was the giveaway. The real purpose of the exercise was to make her prove her conjecture with measurements--to translate the theory to practice. I also wanted her to explain why this sexual dimorphism--that is, this sexually determined physical difference--is not nearly so pronounced in nonhuman primates, such as chimpanzees.

She spoke: Males have one fewer pair of ribs than females.
When teacher Robert S. Root-Bernstein got this answer to his question on how you should distinguish between male and female skeletons, he had to find a way to make her realise her error without disparaging her religion.

If we're not in pain, we're not alive

You invest so much in it, don't you? It's what elevates you above the beasts of the field, it's what makes you special. Homo sapiens, you call yourself. Wise Man. Do you even know what it is, this consciousness you cite in your own exaltation? Do you even know what it's for?
Dr. Peter Watts is no stranger to MetaFilter. But look past his sardonic nuptials, heartbreaking eulogies, and agonizing run-ins with fascists (and fasciitis) and you'll find one of the most brilliant, compelling, and disquieting science fiction authors at work today. A marine biologist skilled at deep background research, his acclaimed 2006 novel Blindsight [full text] -- a cerebral "first contact" tale led by a diverse crew of bleeding-edge post-humans -- is diamond-hard and deeply horrifying, wringing profound existential dread from such abstruse concepts as the Chinese Room, the Philosophical Zombie, Chernoff faces, and the myriad quirks and blind spots that haunt the human mind. But Blindsight's last, shattering insight is not the end of the story -- along with crew/ship/"Firefall" notes, a blackly funny in-universe lecture on resurrecting sociopathic vampirism (PDF - prev.), and a rigorously-cited (and spoiler-laden) reference section, tomorrow will see the release of Dumbspeech State of Grace Echopraxia [website], the long-delayed "sidequel" depicting parallel events on Earth. Want more? Look inside for a guide to the rest of Watts' award-winning (and provocative) body of work. [more inside]

Evolution: Maybe It's Not Just for the Fittest Anymore

Is it time to put natural selection in its place? Jello Biafra once famously wrote that "If evolution is outlawed, only outlaws will evolve." But while it likely comes as no surprise to specialists working in the field or to those who've been following developments in evolutionary biology closely, there's an emerging view among experts that Darwin's view of natural selection as the primary driver of speciation and evolutionary change may be incorrect or at least drastically overstated. It's long been understood that non-adaptive evolutionary mechanisms like "genetic drift" and random mutation also play non-trivial roles in evolutionary processes, but a recent study (link to abstract with full-text PDF available) casts new doubts on the primary role of natural selection, finding that "Neutral models, in which genetic change arises through random variation without fitness differences have proven remarkably successful in describing observed patterns of biodiversity."

State of Nature

“When I spoke at the two Ron Paul events in Tampa, a young man kind enough to pick me up at the airport told me a fascinating story. The vast majority of young Ron volunteers in offices he visited all over the country were paleo. If a kid ordered pizza — which was always the primary or perhaps only campaign food — he was practically booed,” Atossa Araxia Abrahamian writes in The New Inquiry about the paleo diet, libertarianism, and the appealing idea of a healthy, undistorted state of nature to which we can return if we are only pure enough.

The Secret Lives of Raccoons

"In an effort to outwit raccoons, are we pushing their brain development and perhaps even sending them down a new evolutionary path? Using high-definition, infrared cameras that turn pitch dark into daylight ... Raccoon Nation [alt link] achieves something that has never been done before: it intimately follows a family of urban raccoons over the course of six months as the young – under the watchful eye of their mother – grow, develop, and begin to find their way in the complex world of a big city." "Raccoon populations have grown twenty-fold in North American cities over the last seventy years. And as this documentary will show, city life is changing raccoons in remarkable ways."

Time Tree

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. A search utility allows exploration of the thousands of divergence times among organisms in the published literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen taxa, such as species, compute summary statistics, and present the results . . . For those interested in published summaries of relationships and divergence times of major groups of organisms (family level and above), see the authoritative synthesis The Timetree of Life.

Here are some examples to get you started: Humans and Chimpanzees diverged 6.3 MYA; Giraffes and Dolphins diverged 58.3 MYA; Cats and Mice diverged 95.2 MYA; and Dogs and Fleas diverged 777.8 MYA. [more inside]

Creationism stays out of Texas textbooks (for now)

On Friday, July 22, the Texas Board of Education voted 14-0 to support scientifically accurate high school biology textbook supplements, rejecting the proposed creationist materials.

Digitized Darwin

More than 300 heavily-annotated books from Charles Darwin's personal library have been digitized in a collaboration between Cambridge University, which holds the collection, and the Biodiversity Heritage Library, a project that has so far digitized nearly 50,000 titles from the natural sciences. And if you're looking for what Darwin wrote, rather than what he read, the University of Oklahoma has digitized the first edition of each of his 22 books.
