Crazy People

  • Some Russian person decided to beat the traffic by driving on the wrong side of the road, backwards no less. The thrill to see who can get a ticketed or injured in an accident first apparently enticed quite a few people.
  • Crazy lady awed by the existence of rainbows - thinks chemicals in the drinking water are to blame. This one kills me every time; the meandering rant is just so breathtakingly, mind-bogglingly idiotic that it simply has to be a joke.

Evolution 101



Among popular misconceptions of scientific theories, evolution is by far the worst. It astounds me how horribly evolution is framed in popular culture and how maligned it is in public discourse. It is no doubt a result of the Christian-Republican campaign to stifle the teaching of evolution and inject religious dogma straight into the science classroom.

Firstly, among creationists it's abundantly clear that few (if any) of them even understand the scientific theory in the first place. I can't count how many times they have considered "proof" of evolution to be a cat giving birth to a dog or an individual chimpanzee spontaneously metamorphosing into a human overnight. The ignorance is baffling, but unsurprising - these people have been told that evolution is a direct threat to God, so it makes sense to manufacture such self-deceits in a misguided attempt to protect their beliefs.

Not once do they hit on the remarkably simple real idea - that evolution is simply accumulated genetic change from one generation to another. Instead, they attack a strawman of their own devising in an attempt to justify their beliefs.

Straight-line evolution


Like the horribly bad starfish-->fish example, people sometimes think of evolution as a one-way ticket, with a single species "improving" up to a radically different form. The seductive thing about this misconception is that it's partially true - you can trace a current species lineage from its more humble ancestors, but that's only part of the picture. In reality, speciation involves lots of daughter species and many extinctions. It's a messy affair. And the notion of "progress" in evolution is mistaken - fitness is all about surviving in the current environment, and adaptions always have their disadvantages. Examples in nature abound - pangolins have forelimbs so well adjusted to digging that they're no longer very good for walking, leaving pangolins with a hobbling gait. Also, every once and a while, a species seems to "devolve" and go against our vaunted notions of progress - for example, cave fish that no longer have functioning eyes.

Clade-skipping




Also like the starfish example, creationists seem to think that evolution operates by species launching from their branch in the nested hierarchy to another branch - what was once an echinoderm is now a full-fledged chordate! Sorry, it doesn't work that way; species form a nested hierarchy and continue to evolve, but a mammal species is never going to become a bird species, no matter how much time elapses, their common ancestors have long ago diverged from each other, never to reunite. If they did, that would pose serious problems for the theory of evolution.

Common objections to evolution:

But it's just a theory!


That's true, it is a theory. Heliocentrism is also a theory. Scientific theories are models used to explain facts and scientific laws are mathematical relationships. There's no hierarchy of accuracy - theories don't graduate to law status, no matter how well supported they are by the evidence.

It's morally wrong




A favorite tactic amongst creationists is to throw out irrelevancies - changing the topic from whether or not evolution happens to whether or not evolution is "bad". It's an absurd ploy - no matter how distasteful the facts are, they don't stop existing merely because one doesn't like them - I can't close my eyes and make the world disappear.

It's atheistic



This is the mother lode of objections. I love it because it betrays the motivations of the speaker so well - the main gripe against evolution isn't on factual grounds at all, but on theological grounds.

Well, it's true that the theory of evolution doesn't have much to do with God. Neither does any other scientific theory. Science itself is agnostic on the subject.

But the intent of this objection is to label evolution an "atheistic science" and therefore make it anathema to all theists.

Once again, it's an irrelevant objection - evolution either happens or it doesn't, theological quandaries need not apply.

Cowboy Churches

Where prayers come with a twang

Hilarious article. Apparently, there are cowboy-themed churches in the US. Sounds gimmicky, but that's how religion stays alive in the US - many megachurches try to attract young people with modern music.

"Some evangelical Christians have questioned whether the churches only offer gimmicks and fail to provide a meaningful spiritual experience."

I'm no fan of gimmicky churches, but this is like the pot calling the kettle black. Evangelical Christianity doesn't have much out on offer besides right-wing politics, disliking gays, and an eager anticipation of the end of the world.

"Another movement, though, grew out of a Baptist outreach to ranchers in Texas that spread like a wildfire, spawned megachurches and now even sends cowboy missionaries to Africa."

Cowboy missionaries. Hilarious.

"And the sermons usually last just a few minutes so as not to make the audience restless."

Good plan. The ones I'm used to took almost two hours (subjectively several years), and I doubt that very many enjoyed the experience.

"The evangelical magazine Christianity Today asked in a blog in May: 'Clearly something is going on here, but what?' Blog moderator Derek Keefe questioned whether the movement expanded or collapsed the Christian gospel message."

In other words, the concern is whether this sort of marketing helps or hinders the survival of the meme. In the short term, it probably does, by attracting people who ordinarily wouldn't go to church. In the long run, I doubt it though. Fusing popular culture and religion - the Mc Religion approach - is thoroughly self-embarrassing and fails to counter historical trends eating away at traditional religions, like secularism and modernism. You simply can't get people to buy a product they no longer want or need, no matter how well you market it.

Religious police ban pets

Saudi capital bans pet walking, buying

Part of the ongoing effort to make the world a less free and happy place. And by a religious authority, no less.

Apparently, it's because they're scared that the irresistible pet cuteness will cause young men and women to flirt with each other. Allah forbid.

With a Ph. D in Horribleness

I laughed, I cried, I loved it. Best web movie evar.
