I’ve been hearing about this problem for a while now.

Bananas are something of a miracle of horticulture and human tinkering with what evolution done wrought. In their natural state, bananas are rather icky-looking squat things that require some considerable effort to make edible, but when most people think “banana” they think of the Cavendish banana, which first appeared on the scene in 1836 in the form of a single mutant plant. This was yellow and tasty and could be eaten right out of the peel. It was, in essence, pretty awesome. But there’s a problem: all modern Cavendish bananas derive from that *single* plant. Which means they’re all pretty much clones. Which means they would, in theory, be capable of being wiped out by a single plague… if one plant is susceptible to it, they all would be.

Good news, everyone!

Get ready for the banana pandemic to destroy your favorite fruit

Bananas have been struck by plagues before. Another strain, the “Gros Michel” type, was the standard-banana until the 1950’s. At that point, the strain was virtually wiped out by the “Panama disease.” It didn’t make the strain extinct, but it made it rare enough to cease to be economically meaningful, and was replaced –  after considerable effort and expense – by the Cavendish. Until relatively recently the Cavendish was thought immune to the Panama disease. Guess what.

Related: here’s a mutant fruit.

Here’s what this type of mutant fruit actually believes happened: dinosaurs with sharp flesh-rending fangs were actually vegetarians who lived less than 6,000 years ago and ate fruit that only appeared less than 200 years ago:

Think I’m kidding? Prepare to be disappointed.

At first this looks like progress:

Creationist radio ad: Evolution cannot be debunked with reason

In a 60-second radio ad released Thursday, Answers in Genesis President Ken Ham admitted there was no scientific evidence that conclusively demonstrated that evolution was a lie.

But then…

“We have solid proof in in our hands that evolution is a lie: the Bible,” Ham explained. “You see, we can’t depend solely on our reasoning ability to convince skeptics. We present the evidence and do the best we can to convince people the truth of God by always pointing them to the Bible.”

Oy.

Neat:

X-Rays of Iconic Fossil’s Feathers Reveal Color Patterns

This is interesting not only in that it helps to put some detail into our knowledge of the distant past, but also because the light it helps cast on some of the sadder aspect of humanity. There are a number of people who believe that the Archeopteryx is not a fossil, but a hoax.  Examples:

THE ULTIMATE HOAX: ARCHAEOPTERYX LITHOGRAPHICA

What Was Archaeopteryx?

The claim that all ten of the known Archeopteryx fossils are frauds, where someone somehow added the impressions of feathers to an existing fossil of the apparently feather-less Compsognathus, was of course quite silly. But to claim that a century and a half ago the forgers looked forward in time enough to salt the fossil with carefully arranged and vanishingly thin displays of nickel and copper compounds? Feh.

West of Denver, just past the first hogback of the Rocky Mountain Foothills, is “Dinosaur Ridge.” An exposed slab of sedimentary rock, tilted up prit near 90 degrees, is liberally covered with dinoaur footprints.

In this panorama, the main display is visible about 3/8 of the way across from the left.

Used to be, back when I lived in the area (more’n a decade ago), you could drive right on up the road and take a look. Now the road is blocked off with gates. You can walk up it or bike up it, but no cars. Kind of a pain in the keister.

National Geographic has an article about Göbekli Tepe (which I’ve previously posted about HERE)

The Birth of Religion

In short, it’s a monumental ceremonial site in Turkey, built approximately 11,600 years ago. In contrast, the pyramids of Giza were built about 4570 years ago. A millenia before the pyramids were built, Göbekli Tepe was already older than recorded civilization is *today.*

The arguement being made at the Nat Geo article (and it’s not a new one)  is that Göbekli Tepe was built before agriculture had been invented. It was a purely religious site with no signs of it being any sort of urban center. So people with no written language, no use of metals, probably no domesticated animals built this site *miles* away from a water source. Entirely irrational, and entirely human.
