Are All Marine Scientists Moonbats?
Get a load of this bit of silly. Some scientists find a new species of giant clam up in the north end of the Red Sea. There aren’t very many of them ... perhaps that’s why they haven’t been found until now? So right away they spin up a theory ... no, not global warming, not yet ... but that the clams were over fished by early man when they first go the hell out of Africa all those thousands of years ago. Yup, the only reason they can figure that the clams aren’t wall to wall under the sea is because evil humans ate them all once upon a time. Funny though, if most of these wonder clams were eaten up then, then why haven’t they made a comeback since? They’ve had 125,000 years to do it. Even clams must be able to breed better than that.
Giant clams two feet long might have helped feed prehistoric humans as they first migrated out of Africa, new research reveals. The species, Tridacna costata, once accounted for more than 80 percent of giant clams in the Red Sea, researcher now say.
Today, these mollusks, the first new living species of giant clam found in two decades, represent less than 1 percent of giant clams living there.
This novel clam, whose shell has a distinctive scalloped edge, was discovered while scientists were attempting to develop a breeding program for another giant clam species, Tridacna maxima, which is prized in the aquarium trade. The new species appears to live only in the shallowest waters, which makes it particularly vulnerable to overfishing.
“These are all strong indications that T. costata may be the earliest example of marine overexploitation,” said researcher Claudio Richter, a marine ecologist at the Alfred-Wegener-Institute for Polar and Marine Research in Bremerhaven, Germany.
Fossil evidence that the researchers uncovered suggests the stocks of these giant clams began crashing some 125,000 years ago, during the last interval between glacial periods. During that time, scientists think modern humans first emerged out of Africa, Richter said.
These mollusks could have played a key role in feeding people during that crucial era, serving as a prime target due to their large size, the scientists added. Indeed, competition for these clams and other valuable sea resources “may have been an important driver for human expansion,” Richter told LiveScience.
Underwater surveys carried out in the Gulf of Aqaba (north of the Red Sea, between the Sinai Peninsula and Arabian mainland) and northern Red Sea revealed this long-overlooked clam must be considered critically endangered. Only six out of 1,000 live specimens the scientists observed belonged to the new species. This mollusk could be the earliest victim of human degradation of coral reefs in this region, the researchers added.
Natural selection? Survival of the fittest? Adapting to changing conditions? Don’t know what any of that means! If we find some critter, and there aren’t zillions of them, then there is one and only one reason for it: evil human degradations!! Either that, or this bunch of researchers needs an new influx of grant money, so this is just a bid to get some fiscal attention.
Once upon a time you could trust scientists. Now they’ll say anything for money. And it looks like the moonbats have taken over there too.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:
It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.
- Keep a firm grasp of Right and Wrong
- Stay involved with government on every level and don't let those bastards get away with a thing
- Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
- Keep talking to each other, whether here or elsewhere

Oh, and here's some kind of visitor flag counter thingy. Hey, all the cool blogs have one, so I should too. The Visitors Online thingy up at the top doesn't count anything, but it looks neat. It had better, since I paid actual money for it.
