...this is simply awesome:
Whale 'missing link' discovered
by BBC News
The whale is descended from a deer-like animal that lived 48 million years ago, according to fossil evidence.
image description Remains found in the Kashmir region of India suggest the fox-sized mammal is the long-sought land-based ancestor of whales, dolphins and porpoises.
Research in Nature suggests the animal lived mainly on land but dived into water to escape predators.
Whales are known to be descended from land-dwellers but the "missing link" has been a mystery until now.
Although Indonyus, as it is known, looks nothing like the whales of today, it shares certain anatomical features.
The structures of its skull and ear are similar to those of early whales, and like other animals that spend a lot of time in water, it had thickened bones that provided ballast to keep its feet anchored in shallow water.
"We've found the closest extinct relative to whales and it is closer than any living relative," said study leader Professor Hans Thewissen of the Department of Anatomy at Northeastern Ohio Universities College of Medicine in Ohio, US.
Hippo link image description
Indonyus belongs to an ancient order of mammals that had two or four toes on each foot. Modern day representatives of the group include camels, pigs, and hippopotamuses.
DNA studies show that hippos are in fact closely related to modern whales. They do not appear in the fossil record, however, until about 15 million years ago, some 35 million years after the cetaceans originated in south Asia.
This led Professor Thewissen and his team to search for an older land-based ancestor that would fill in some of the gaps in our knowledge of the whale's dramatic evolutionary journey from land to sea.
After seeing loose teeth and fragments of jaw bones found by the late Indian geologist A Ranga Rao some 25 years ago, Professor Thewissen obtained rock samples from Rao's private collection. They harboured a treasure trove of complete Indohyus fossils, including skulls and leg bones.
Dietary clues
The stable-oxygen-isotope composition of its teeth suggest that the animal spent much of its time in water.
Some have assumed that the ancestor of whales first took to the water to feed on fish but the latest evidence suggests otherwise.
"The new model is that initially they were small deer-like animals that took to the water to avoid predators," Professor Thewissen told BBC News. "Then they started living in water, and then they switched their diet to become carnivores."
Although the behaviour and habits of Indohyus appear somewhat strange, there is a modern day parallel in the African mousedeer (chevrotain).
The mousedeer lives on land, but is known to leap into the water to avoid predators such as eagles.

Unholy Racket No 003: They have been judged
Lest this blog degenerate into seriousness, I feel like some comic relief is in order.
PBS ombudsman writes about Judgment Day, a Nova production on Kitzmiller v Dover School District trial. The article itself may be of interest to those unfamiliar with the case (huh? is that even possible?), but the true gems are the letters received by PBS regarding the show. Some of my favourites follow. Behold the flights of pure idiocy!
Towards the top of the page we have this—clearly, a product of a deep and penetrating mind:
"It doesn't take a "Rocket Scientist" to figure out that if we, as humans, evolved from monkeys . . . THEN WHY? . . . Are there STILL Monkeys??? We were "Created" by God!!! Pull up AOL now and you'll notice the Gov. of Georgia praying for rain, (No Doubt to GOD). When 9/11 happened what did every good neighbor do? PRAY. Not to monkeys . . . To our "Creator"!!! It shouldn't take tragic and desperate circumstances for people to realize this fact!!! GOD BLESS AMERICA!!! In GOD We Trust!!!
Sonya L. Johnson, North Port, FL"
Once you've stopped chuckling, you'd do well to remember that the "monkey" argument is in fact rather pervasive; other letters refer to it, for example:
"If evolution were true and man "evolved" from apes, why do we have apes and monkeys co-existing with man? Why have the apes not all turned into humans?"
Of course, all those nonstarters show is the letter-writer's complete ignorance of evolutionary theory and possible lack of functioning grey matter. Onwards!
Another popular argument is the appeal to fairness; this comes from a viewer concerned that ID did not get a fair hearing:
"What are you people afraid of? I am concerned for the viewer who is not familiar with the major tenants of both sides of the argument. I am only a lay person, but I know enough about the issue to see that a fair hearing in your format is not tolerated."
Naturally, "both sides of the argument" exist only in the fevered imagination of IDiots and creationists and their ilk (fevered? this may be a misuse of the word; "pedestrian" and "dull" and "non-imaginative" may be better descriptors). There is no intellectually serious opposition to the modern synthesis. This does not mean that some theory may not arise in the future, overturning all that we believe now (although it is unlikely, to put it mildly, but possible). It means, however, that Intelligent Design isn't that theory. This alleged controversy only exists in the minds of—dare I say it—those without any idea of what they are talking about. Clueless idiots often are the loudest kids on the playground; so here.
The "immoral implications" of evolution follow, mixed in with a dubious claim grounding human morality in religion:
""Survival of the fittest" follows from evolutionary theory. Evolutionists, to be logical and true to their faith (it takes faith to believe in it since there is no clear, unimpeachable physical evidence for macro-evolution) should see nothing wrong with what Hitler, Stalin, Pol Pot, etc., did in the genocides of millions of people. Since the exterminated ones were "weak," in terms of evolutionary faith, evolution proponents should all just shrug off these murders as being inconsequential (which is how the ones responsible for the murders saw them). But most don't, and the reason is we know those were atrocities. We know to murder another human being is wrong. And we know this because we have consciences given to us by our Creator."
Where do I start? "no clear unimpeachable physical evidence": there is no such beast anywhere in the history and practice of science. There are degrees of certainty; evolution is highly certain, more so than, say, M-theory, or, closer to earth, our description of the many bonding agents (glues, y'know) that we use on an everyday basis. And, of course, the appeal to God as the basis of our morality is pure bullshit, undiluted, ignoring many ethical theories constructed specifically on a non-theist basis, while substituting fear-based subservient (anti-)ethics for reality.
Finally, there is a slew of letter-writers who complain about the short shrift religion in general received in that program. They should keep in mind that this particualr episode was about history: any accusations of bias may just as well be directed against court transcripts. Any accusation of a bias towards a given ideology fails. An attempt to inject some religious ideology—even moderate Godtalk—into the program would have been precisely unprofessional, sunce the subject had nothing to do with the existence of gods or the validity of any religious belief. It was all about teaching religion in a science class. That's all, and those unhappy with the direction of this episode should consider that it is not the job of PBS to present every argument in every show. There is plenty religious claptrap on the idiot-box already. Claims of "evolutionist" bias are ridiculous. Fuck off already and go sit in your Dark Age corner.
Another favourite, and one that almost needs no rebuttal is "I have a degree in journalism and could easily point out every instance of yellow journalism in this show.". Yeah, you may have a degree in journalism but you are obviously quite ignorant of either biology or the actual court case in question!
Enough! What had started as a light humorous attempt to look at the silliness of some people is turning out to be a depressing peek into the idiocy of humanity in general: the majority of letters on that page follow the same format, and it all becomes rather sad, eventually. One can only ingest so much pure ignorance, nonsequiturs, ALL CAP screaming and so many logical fallacies in one sitting. Fuck 'em.

her face was an ell broad and her teeth were about the same size
There has been a crop of beautiful books on atheism and the stupidity of ID/creationism over the last six months or so. The God Delusion, the new edition of Atheist Universe, Letter to a Christian Nation, God: The Failed Hypothesis, Why Darwin Matters, Why Intelligent Design Fails, The Counter-Creationism Handbook, and others (!)
In any case, some of these books have been constituting my reading material while I take the bus to work each bloody morning and back each exhausted evening...Finally, someone at work asked me, with a slightly offended air, if I only was ever interested in one side of the argument and whether that did not constitute an indication of a closed mind on my part. That was funny. But, honestly, of course I read the opposition. I've read Phillip Johnson and laughed. I read Duane Gish and fell out of my chair, weeping with merriment. Their kind perform a useful purpose: they lift up our spirits by showing how perfectly idiotic humans can be; they ignore science, misrepresent its conclusions, come up with their own rather strange philosophical concepts and generally spend their time standing in the corner blocking their ears with their hands and shouting "Nyaah Nyaahh I can't hear you". Very funny.
I knew that that wasn't the kind of response my questioner wanted to hear, but what the hell? OK: I've read Behe and Dembski, and they weren't even really funny, although they also committed most of the aforementioned fallacies. They just did it in a very self-importantly aggrandazing and serious way. Those two are difficult to laugh at, but, really, their suggestions have been debunked rather thoroughly: just for starters, a whole bunch of articles are here. Easy enough.
But what about "sophisticated" theology? Well, indeed. Just finished reading Haught's Deeper Than Darwin, and am now plodding through McGrath's Twilight of Atheism. But not on the bus!!! See, I want something fun on the bus, and since I do not find appeals to revelation and subjectivity convincing and informal logical fallacies of various stripes no longer even make me very angry, McGrath would just put me right to sleep (in fact, if it were less generally unpleasant, I'd be reading this kind of material before going to bed: gently relaxing one's critical faculty and helping one shut off one's brain). Haught is a bit more contentful, but even so, if that is the best that "sophisticated" theology can throw at us, we are not in any trouble (logically, anyway). Nobody but believers would be convinced by any of the arguments therein; books like that serve only as a confirmation, a support of sorts: see, somebody out there thinks like you do, you are not alone, we can make silly errors and be confused together.
Blecch. Today, however, no such fun. My bus reading will consitute papers on evolution of photosynthesis and possible detection of such in extrasolar planetary atmospheres. Hey: it may not be funny, but it will be exciting!
