How much do you know about antibiotic resistance? You might want to take the Pew Charitable Trust’s online quiz to find out. I’m embarrassed to say that I scored only 60%, despite my many years hanging around microbiologists. I got the biology questions right, but I didn’t know how many more days Americans spend in the hospital because of antibiotic resistant infections, nor how much antibiotic resistant infections cost our health care system.

This week’s Fossil Friday comes to you straight from the middle Eocene. This is a photo of a lower jaw found in what is now Sweetwater County, Wyoming. This fellow’s family has been mistaken for the tapir’s family, and though it does share an early ancestor, I can assure you it is different. 

This will be a true test of your tooth-knowledge. How much can you tell from just this lower jaw?  Can you guess what this fossil is?

There’s a big, sandy problem with Noah’s Flood.

I’m working my way, slowly, toward talking about a particularly strange argument that appears in David Hume’s Dialogues concerning Natural Religion (1779), which bears on the age of the world. In part 1, I explained that the argument occurs in the course of a response in part VI of the Dialogues by the character Cleanthes (whose argument from design rests on the analogy between the world and a machine) to his critic Philo’s objection that the world is as much like an animal as it is like a machine.

That's not a straight line! This display at the Thomas Condon Paleontology Center near Kimberly, Oregon shows just how diverse the Equidae family tree is. (Photo courtesy of Mark Terry)

The Jehovah's Witnesses visit me once a year. They politely try to convert me; I politely turn down the offer. They leave me a colorful pamphlet which I never read and that's that.

Recently, a creationist blog attributed a particular argument against design to David Hume, so I took a copy of his Dialogues concerning Natural Religion (1779) from the shelf to check. Surprise, surprise: it wasn’t there. But I’m not going to bother to debunk the misattribution; it’s not really interesting. Instead, as long as I have the Dialogues before me, I thought that I would say a word about a particularly strange argument that appears in it, which bears on the age of the world.

Last week I told you to take it slow on identifying this fossil. As we all know, slow and steady wins the race, or in our case, comes up with the right answer!

Next week, I’m going to get back to actual misconceptions for Misconception Monday posts, I promise—but I am a “completer-finisher,” according to some workplace personality test I once took, so I need to round out this trio. Last stop on my mini-tour of you-can’t-show-that-in-textbooks-anymore topics: Horses!

Denial: a big word loaded with emotion. But, like many things in life, denial is a continuum: from full blown outright dismissal to more subtle avoidance, like looking the other way.
