Recently in Evolution Category

First things first. The 3-part series is called Becoming Human, and it begins tonight at 8 p.m. Eastern time (and 7 p.m. my time, so check your local schedule).

The website, which is in a beta edition right now, is called simply “Evolution.” Today, it features articles on Becoming Human, Evo-Devo, and The Evolution of Motherhood, among others. It looks as though a regular feature will include links to recent news articles, and there are also links to apparently original material by Neil Shubin, Sean Carroll, and Carl Zimmer. There are additional links to a number of relevant books and websites. Finally, you can watch “Intelligent Design on Trial” and “Darwin’s Darkest Hour” just by following links prominently displayed on the “Evolution” website.

Smithsonian to open Human Origins Hall

| 24 Comments | No TrackBacks

In spite of the Disco ‘Tute’s recent efforts to imply that the Smithsonian Institution is somehow sympathetic to anti-evolutionist films, the stodgy old place persists in being a place where evolution education is important. Most recently it has announced (pdf of press release) the upcoming opening of a new exhibition hall devoted to human origins:

A new exhibition hall dedicated to the discovery and understanding of human origins will open next year at the Smithsonian’s National Museum of Natural History. Based on decades of cutting-edge research by Smithsonian scientists, the David H. Koch (pronounced “coke”) Hall of Human Origins will premiere March 17, 2010, which also marks the 100-year anniversary of the museum’s official opening on the National Mall.

The $20.7 million exhibition hall will be complemented by ongoing human origins research and education programs, which are all key components of the museum’s broader initiative, “Human Origins: What Does It Mean to Be Human?” The initiative focuses on the epic story of human evolution and how the defining characteristics of the species have evolved over 6 million years as its ancestors adapted to a changing world. The museum will launch a compelling new Smithsonian Human Origins Web site and a revolutionary virtual experience hosted on the Blue Mars 2150 virtual Web site. It will include a complete reproduction of the physical exhibition plus additional features visitors can only experience on the Web.

It’s noteworthy that the main funding is coming from two people with science and engineering backgrounds, the eponymous David H. Koch, a chemical engineer and executive vice president of Koch Industries, and Peter Buck, a physicist and co-founder of Subway restaurants. It’s good to see there’s significant science philanthropy to offset the likes of Howard Ahmanson, a major funder of the Disco ‘Tute.

Fossilized Ripples

Fossilized Ladder Ripples, Torpedo Creek Quarzite near Mount Oxide in the Western Succession of the Mount Isa Inlier, Queensland, Australia. In environments such as tidally influenced areas, water currents often go in different directions, resulting in unusual ripple patterns (hard to explain tidally influenced areas in a global flood). Torpedo Creek Quartzite is about 1.69 billion years old.

One of my favorite examples of the step-by-step evolution of molecules has been the work coming out of Joe Thornton's lab on glucocorticoid receptors. It's marvelous stuff that nails down the changes, nucleotide by nucleotide.

It's also work that Michael Behe called "piddling", despite the fact that it directly addresses the claims of irreducible complexity. Have you ever noticed how the creationists will make grand demands (show me how a duck evolved from a crocodile!) and then reject every piece of fossil evidence you might show them because there are still "gaps"? This is the converse of that argument: when you've got a system where you can show each tiny molecular/genetic change, they dismiss that as trivial. You really can't win.

Well, Thornton has been working hard and coming up with more and more details, while Behe is still sitting there, eyes clamped shut and ears stoppered, insisting that IT CAN'T HAPPEN LALALALAALALALALAAAA. Behe threw together some dreck claiming that not only didn't Thornton's work demonstrate evolution, but it actually supported Intelligent Design creationism!

Boy, did he make a mistake.

Remember how when the creationists started playing games with his work, it roused Richard Lenski to slap down Conservapædia hard? We've got a similar situation here.

Joe Thornton has written a beautiful response to Michael Behe.

Read it. Really. It's a whole lesson in important principles in evolutionary theory all by itself. It exposes the ignorance of Behe through and through, and demolishes the premises of Behe's latest foolish book. And it made me feel soooo gooooood.

Blogging on Peer-Reviewed Research

It's yet another transitional fossil! Are you tired of them yet?

Darwinopterus modularis is a very pretty fossil of a Jurassic pterosaur, which also reveals some interesting modes of evolution; modes that I daresay are indicative of significant processes in development, although this work is not a developmental study (I wish…having some pterosaur embryos would be exciting). Here it is, one gorgeous animal.

Today I received this e-mail:

In spite of the (lack of) punctuation in the first line, the links led me to several excellent, convincing, and professional-looking videos with titles like “Evolution is REAL Science #1.” A few more clicks, and I found the home page of the producer, Jeremy Mohn, as well as his blog.

As Matt Young pointed out recently, the fifteen year wait for the complete publication of the Ardipithecus ramidus skeletal material discovered by Tim White, and his research group, is over. The material was finally published in Science and is open access. I will discuss the morphology of Ardipithecus ramidus and its implications in a second post. In this post I would like to look at the geological, environmental, and taphonomic background to the discoveries. I examine these first because they provide strong evidence to back up some of the behavioral interpretations of Ardipithecus ramidus.

Darwin’s Darkest Hour

Update Tonight

That’s the title of a 2-hour NOVA program that will be shown Tuesday, October 6, on PBS. DDH is a drama presented by NOVA and National Geographic. It was written by the British screenwriter John Goldsmith and directed by John Bradshaw. It stars Henry Ian Cusick as Darwin. You may find an interview with the playwright and a wealth of other material, not least the WGBH Evolution website, linked to the website of the program. (Originally posted September 25.)

Darwin blogs the Voyage of the Beagle

| 4 Comments | No TrackBacks

I don’t know how I missed this, but some guy named Charles Darwin is blogging a sea voyage he’s on. It seems he’s keeping a journal, and he is blogging the entries so the rest of us can tag along. Read it as an antidote to the Luskin/Wells stupidity.

Hat tip to Phil Plait.

This week’s Science has a special issue devoted to the fossil hominid Ardipithecus ramidus. It looks as though you may read at least some of the 11 articles free, and you may see a video featuring (mostly) Tim White. The fossil is interesting in part because it appears to show that certain expected traits may be absent from the last common ancestor of chimps and humans.

NESCent has announced a travel award for an evolution blogger to attend ScienceOnline2010 (January 14–17th, 2010, in North Carolina’s Research Triangle Park). Bloggers should submit a blog post that highlights scientific results appearing in 2009, dealing with current or emerging evolutionary research. Posts should be 750–1500 words and must mention the contest.

For complete contest information, visit NESCent.

If you submit something to this contest drop me a line as well, and I’ll try to highlight your entry on PT as well.

Erosional landscape at Zabriskie Point, Amargosa Range, Death Valley National Park. It is composed of sediments from Furnace Creek Lake, which dried up 5 million years ago, long before Death Valley sank and widened.

To keep this short, I’ll just quote the NCSE announcement:

he new film about Darwin, Creation, will be distributed in the United States after all, according to a story in the Hollywood Reporter (September 24, 2009). The film is expected to be released by Newmarket Films in December 2009. Earlier the producer of the film, Jeremy Thomas, lamented to the Telegraph (September 11, 2009), “It has got a deal everywhere else in the world but in the US, and it’s because of what the film is about. … It is unbelievable to us that this is still a really hot potato in America.” A few days later, however, NBC Bay Area (September 15, 2009) reported that a distribution deal was imminent.

In her review of Creation at The Panda’s Thumb blog, NCSE’s executive director Eugenie C. Scott described it as “a thoughtful, well-made film that will change many views of Darwin held by the public – for the good.” It also received praise from Steve Jones in Time Out London (September 22, 2009), who called it “a great film about a great man and a greater theory” and by Adam Rutherford in his Guardian blog (September 23, 2009), where he wrote, “we should … be grateful that this film is moving and beautiful, just like the creation Darwin so luminously untangled,” adding, “Creationists the world over deserve to see it.”

Huzzah!

Cartooning Evolution

| 6 Comments | No TrackBacks

Mark Aldrich of Smith College has posted a prodigious number of cartoons under the title “Cartooning Evolution, 1861-1925.” You may look at thumbnails listed under various categories: Darwin and Evolution, Evolution as Social Comment, Victorian Science, and The Scopes Trial as interpreted by northern and southern newspapers and national magazines. Each thumbnail has a link to a larger image. According to Mr. Aldrich, many of the cartoons are readily available from the Library of Congress and other sources.
