If it's "science" it must be true.

Wild speculation worded as if it were science, published in a "science journal," proves wacky theory of panspermia.

I especially like the figure of "one trillion trillion times more likely" that life originated in the non-frozen heart clay-and water filled of a comet than on earth. Not that anyone has proven that any comets contain liquid water, or clay. That's a big number. It must be true.

If someone can mine a comet, and produce the building blocks of life from it, then we can talk about comets "seeding life." But in the meanwhile, Panspermia is just a way of saying that Earth isn't special enough to have produced life--it's just the telescope owner's version of Special Creation or Intelligent Design. Magic Man Comet done it.

Daily Zoo Animal: #10, Boat-billed Heron

Boat-billed heron Cochlearius cochlearius

Herons, including egrets, are instantly recognizable by their shape: their coiled necks, long wader's legs, and sharp spear-heads of bills. Except for the boat-bill. This odd-looking heron is found in the neotropics, from Mexico to Brazil. It roosts in the safety of high places in trees in the swamp by day, and hunts for small water animals by night. Because of its strange bill shape it was long assumed that it hunted in some unique way, the way that the bill shape of a flamingo, a spoonbill, or a avocet suggests its particular feeding method. One study stated that the large bill was apparently filled with nerve endings that helped the nocturnal bird catch shrimp and fish in the muddy mangroves. A few years later another study claimed that the boat-bill feeds on the same prey in the same areas as the yellow-crowned night-heron, with the large bill serving no unique feeding function. Perhaps the boat-bill's courtship displays, full-contact bill clattering, explains the adaptive purpose of this bird's strange appearance.

This boat-billed heron is in the swamp exhibit in the Bird's World building in Franklin Park Zoo. I was trying to take pictures of other birds (who wouldn't stop moving) for 10 minutes before I noticed it perched on a high platform.
