Browne’s videos elicited gasps from the audience because comb jellies, whose lineage evolved long before other animals with through-guts, had been thought to eat and excrete through a single hole leading to a saclike gut. Browne, however, used a sophisticated video setup to continuously monitor two species that he keeps in captivity, Mnemiopsis leidyi and Pleurobrachia bachei. The movies capture the creatures as they ingest tiny crustaceans and zebrafish genetically engineered to glow red. Because comb jellies are translucent, the prey can be seen as it circulates through a network of canals lacing the jellies’ bodies. Fast-forward, and 2 to 3 hours later, indigestible particles exit through the pores on the rear end. Browne also presented a close-up image of the pores, highlighting a ring of muscles surrounding each one. “This is a sphincterlike hole,” he told the audience.One of the biologists said something shocking and astonishing and completely unScientific: “Looks like I’ve been wrong for 30 years,” said George Matsumoto, a marine bio logist at Monterey Bay Aquarium Research Institute. In most branches of Science you'd get kicked out for questioning ALMIGHTY THEORY. Biology has clearly departed from Science and joined REALITY. REALITY is still a shock, though........ “We have all these traditional notions of a ladderlike view of evolution, and it keeps getting shaken,” says Kevin Kocot, an evolutionary biologist at the University of Alabama, Tuscaloosa. Well, there are other TRADITIONAL views of evolution that fit the FACTS better. Every newly found FACT moves the timepoints for supposedly "advanced" and "late evolved" structures and functions backward toward zero. Every new FACT increases the support for a single invention, a single design, that contains all the purposes and skills and patterns needed by life. Different creatures use different subsets of the design, but all of it was available at the start. = = = = = Historical sidenote: I googlebooked a 1912 invertebrate biology text. It shows a diagram of those aboral pores and says "it is believed" that the pores are not involved in digestion; "it is believed" that leftover waste exits via the mouth. So we have a century of "believing" and no actual looking, until this year. Seems like the actual looking wouldn't require fancy genetic engineering; you could have done it in 1912 by confining the critter in a small flat tank lighted from below; stocking the tank with opaque or perhaps radium-infused food; and then watching with a time-lapse camera. Considering the taxonomic importance of comb-jellies, why didn't anyone try?

Polistra was named after the original townsite of Manhattan (the one in Kansas). When I was growing up in Manhattan, I spent a lot of time exploring by foot, bike, and car. I discovered the ruins of an old mill along Wildcat Creek, and decided (inaccurately) that it was the remains of the original site of Polistra. Accurate or not, I've always liked the name, with its echoes of Poland (an under-appreciated friend of freedom) and stars. ==== The title icon is explained here. ==== Switchover: This 2007 entry marks a sharp change in worldview from neocon to pure populist. ===== The long illustrated story of Polistra's Dream is a time-travel fable, attempting to answer the dangerous revision of New Deal history propagated by Amity Shlaes. The Dream has 8 episodes, linked in a chain from the first. This entry explains the Shlaes connection.
