Positively uncertain

One day while scanning Foxnews.com, I noticed a tab on their Science section titled "Evolution and Paleontology." Curious, I clicked. What I noted amused me. That was a few weeks ago, but the humor remains.

Here are a few of the titles to articles within Fox's E&P section from TODAY:

• Scientists: Biting Insects May Have Killed Off Dinosaurs
• Earlier Evolutionary Explosion May Have Preceded Cambrian
• Frozen Calf May Explain Mammoth's Extinction
• Geology May Have Created Perfect 'Cradle of Humanity'
• Human Evolution Seems to be Accelerating
• Scientist: Human Race May Split in Two in Far Future
• Comet Air Burst May Have Killed Off Mammoths, Restarted Last Ice Age
• Some Neanderthals May Have Been Redheads

My personal fav:

• Prehistoric Cave Bears Weren't So Cuddly After All (question: did somebody once posit that prehistoric cave bears were cuddly?)

Time for your Mister Rogers moment. What do all of these have in common (the last one is a wee bit more challenging)? Then, after you've knocked that question out of the park, what does this say about the concrete certainty that surrounds evolution in the halls of academic learning?

Talk amongst yourselves.
