What Is The Best Dinosaur?

Here’s a video for all those who mistakenly think that any animal’s name ending with the suffix -saur refers to a dinosaur. It’s humor for all us mesozoic-loving nerds. Comedian Dan Telfer confronts the controversial issue of the what the best dinosaur is. His arguments are sound.  And his belittling of the audience is righteous.  However, I humbly doubt his pronunciation of deinonychus. It’s pronounced di-non-i-kus, not dino-nik-us. Who’s the king of paleo-jeopardy now, Telfer?

It’s Not A Dinosaur. It’s A Dimetrodon T-Shirt.

What in the world is it? It’s not a dinosaur that’s for sure. It’s of the genus Dimetrodon, and lived during the Permian Period, 280 to 265 million years ago, predating dinosaurs by a good 35 million years. More closely related to mammals than to reptiles, Dimetrodon measured about 1o feet long, and had two types of teeth, hence the name Dimetrodon, which means Di (two)- metro(measure)-odon(tooth). Having a variety of tooth types, with multiple cusps, is a characteristic of mammals, not reptiles, to name just one of the many differences between the two groups.  And finally there’s the NEW T-Shirt that tells the world that you know that it’s NOT a dinosaur. Unfortunately, the vagueness of the shirt may lead the uninitiated to think that you’re declaring that you’re not obsolete just yet.

A Little About Paleontologist Per Ahlberg

Anyone interested in paleontology, rational thought, or the scourge of creationism might want to read the transcript of an interview with Per Ahlberg, Professor of Evolutionary Biology at Uppsala University in Sweden. His straight talk and wit are refreshing. Here’s a sample:

I think mainstream science has a duty and a responsibility to expose creationism and ID for the pseudoscientific frauds that they are. This is something quite different from engaging them in debate, the way you would do with adherents of an opposing but conceptually sound scientific viewpoint. Scientists must expose them simply because they are frauds, and it won’t do to have large parts of the population bamboozled by the lies and misrepresentations of charlatans… Note that there is an important point here: creationists and ID proponents by necessity attempt to befuddle their audience, not just about the evidence for evolution, but about the nature of scientific enquiry in general. They have to, because it is their only way of concealing the threadbare nature of their own claims. (His emphasis)

From this, it should be clear why I have chosen to take part; though you can add the fact that I enjoy talking to people and presenting my ideas to popular audiences. Money, fame and hot chicks would be welcome but have not been forthcoming so far…

Per Ahlberg is known for his work with fossil tetrapods. His latest contribution is as co-author of a paper about 395-million-year-old tetrapod trackways that were found in Poland. (Here’s a summary of the find by PZ Myers at Pharyngula). And a short video about the find is available on the Journal Nature website. Enjoy!

Trilobites Swim Circles Around Creationists – Part 1

Property Of TheDarwinReport

TheDarwinReport

Apologetics Press is so intellectually anorexic, it’s frightening to imagine the base level of research involved in its preparation of creationist material. It’s like watching a poorly conceived horror movie; on the one hand it’s something to laugh at, and on the other it has the occasional shock, even if it’s just a comically masked killer jumping from behind a door with an over-sized knife. It’s cheap thrills, good for a few chuckles. So, here’s today’s feature —the Apologists had something silly to say about the complexity of the trilobite eye. It begins:

One of the most fascinating finds in the fossil record is that of the long-extinct trilobite. Trilobites resided in the Earth’s ancient oceans, and often are considered to be the world’s first arthropods—creatures that consist of hard shells, and that have multiple body segments and jointed legs. Trilobites, which possessed a hard exoskeleton, bear a resemblance to horseshoe crabs, and are thought by evolutionists to be one of the first animals to have lived on the Earth. [my emphasis]

Ah, the errors run like a river: 1) Old-earth creationism invariably involves typological thinking; in other words, some group of organisms must be a “type” without the word ever being adequately defined. Here the Apologists roll the more than 20,000 species of trilobite into one type, as if they were referring to a single creature; and throughout the remainder of the article, trilobite traits are lumped on to that type with complete disregard for the immense diversity that exists within the class, Trilobita. 2) And which paleontologist claims that trilobites were the first arthropods? The first arthropods are thought to have been leggy segmented soft-bodied worms from the Early Cambrian. In fact, if you were to remove all that armor from a trilobite it would look like a worm. It’d be like peeling an artichoke, where there isn’t much underneath. 3) Next, the Apologists claim “evolutionists” think of trilobites as the “first animals to have lived on Earth”. How does it work out that trilobites were the “first arthropods” and the “first animals”? What 19th century children’s encyclopedia have these dimwitted clowns been reading? The sponges might have something to say about who the first animal was.

Let’s wallow in the rest of the Apologists’ misconceptions:

Evolution postulates that all living animals have progressed from simpler creatures, and that by the process of natural selection, organisms have “improved” along the way. Conventional thinking, therefore, suggests that since trilobites are so ancient, they must have been fairly simple creatures with primitive features. However, the eye of the trilobite—which is incredibly complex—refutes such a concept.

Yeah, well, when you disregard the tens of millions of years of natural history that occurred prior to the trilobites’ reign, it’s easy to make that argument. If no creatures with simpler eyes than trilobites had existed, then there would be a problem. But since there’s plenty of evidence to the contrary, the flaw clearly lies in the Apologists being willfully ignorant of the subject matter.

Most trilobites had a pair of compound eyes that were made up of 100 to 15,000 lenses in each eye.

Such intricacies suggest that evolution is a degenerative process, for nothing on Earth today compares to the eye of the trilobite.

Darwinian models that attempt to explain the trilobite’s eye are completely unable to account for such complexity, especially considering the fact that the trilobite is considered to have evolved so early. When one considers the complexity of the trilobite’s eye, and compares it with the considerably less-complex eye systems of animals and/or humans today, it would seem that evolution has “gone in reverse.” [my emphasis]

Additionally, they go on to quote-mine paleontologist Niles Eldredge, who only speaks to the complexity of the trilobite lens, not the entire eye. The unique characteristic of the double-layered lens (doublet) of the trilobite is that it corrects for the aberration that occurs when light travels from a less dense material like water to a more dense one like calcite (CaCO3), which is what the trilobite lens –and exoskeleton, not coincidentally– is made of. But the human lens is, in fact, more complex because it can change shape to focus, while the trilobite lens is fixed. What the Apologists don’t grasp is that evolution is adaptive and not progressive in the long term, and that the variation in nature demonstrates how many ways there are for solving the same problem. How many different types of eyes are there? Moreover, they fail to see that eyes don’t see; eyes merely collect light and convert it to signals for the brain to interpret. Are the Apologists going to argue that the trilobite brain was more complex than the human brain? They can speak for themselves –and their own brains– on this point. Are you smarter than a trilobite? Now that’s a game show I’d watch. Trilobites win every time.

Young Australians Revolt Against Gullibility

Young Australian Skeptics

When I was 7 years-old my favorite subjects of conversation were Bigfoot and UFO’s. I eagerly believed in both of these questionable phenomena based solely on “the evidence” provided by cheesy TV shows. Boy, was I a major drongo (Australian slang for a stupid person). Well, I would have been if was an Australian. I’m not. I’m an American, so technically I was a dumbass. But America and Australia share a common problem. Both countries are plagued with creationism and other pseudo-scientific, and anti-intellectual movements, COUGH religion COUGH. Rev. Ken Ham is an export of Australia, I’m sorry to say.

So, it’s only natural that an organization of young Australians would spring up to encourage others to be more discerning and skeptical. It’s called Young Australian Skeptics: A Sanctuary for Young Free Thinkers. Check it out, or you’ll go to hell. What, you doubt me? Do you want to take that chance? But what if you’re wrong?

What’s Wrong With Being A Mad Scientist?

Fictional mad scientists are most often portrayed as highly driven and glory hungry; they are the unwitting villains, the victims of their own inquisitive natures. Author, Reto Schneider, has written The Mad Science Book, which chronicles the history and present of questionable experiments carried out by real-life “mad” scientists. A list of nine of these experiments is on The New Scientist website. My favorite is Dogbot, the robot dog that was a social reject. Real dogs wanted nothing to do with him. Maybe his nose glowed red or he aspired to be a dentist. Whatever the reason, Dogbot was not allowed to participate in dog games.

What I like about mad experimentation is it’s raw unbridled curiosity. What does it matter if some experiments go wrong or if others are completely useless and outright wacky? What counts is that humans have a desire to understand the world. Thomas Edison was a mad inventor; he wasted ten years of his life on devising a new mining technique, which failed miserably. He also designed furniture and homes made out of that comfortable substance know as concrete. Not big sellers.

The lesson here is that in a complex world, curiosity saves the cat, it doesn’t kill it. But still there is an intellectual divide in society. There are those who care to know the world, and those who don’t care to have their world views tarnished by reality. I’m talking about creationists here. To them a mad scientist is someone to be feared.
