Overlooked : Slackers in Nature

Earlier this morning, Tim O’Reilly tweeted about this research published in the NYT and I am so completely fascinated and thus fixated on it today:
Dr. Dornhaus is breaking new ground in her studies of whether the efficiency of ant society, based on a division of labor among ant specialists, is important to their success. To do that, she said, “I briefly anesthetized 1,200 ants, one by one, and painted them using a single wire-size brush, with model airplane paint  Rally Green, Racing Red, Daytona Yellow.â€Â
After recording their behavior with two video cameras aiming down on an insect-size stage, she analyzed 300 hours of videotape of the ants in action. She discovered behavior more worthy of Aesop’s grasshopper than the proverbial industrious ants.
“The specialists aren’t necessarily good at their jobs,†she said. “And the other ants don’t seem to recognize their lack of ability.â€Â
Dr. Dornhaus found that fast ants took one to five minutes to perform a task  collecting a piece of food, fetching a sand-grain stone to build a wall, transporting a brood item  while slow ants took more than an hour, and sometimes two. And she discovered that about 50 percent of the other ants do not do any work at all. In fact, small colonies may sometimes rely on a single hyperactive overachiever.
Why do some worker ants lean on their shovels and let the rest of the workers do all the work? “It’s like students living together  you’ll always find one will have a lower threshold for doing the washing up and will end up always doing it all,†she said.
It’s amazing it took us so long to figure this out – what with all the ant farms we’ve been watching for years and years. No one seemed to notice the slackers until now. Perhaps, they’re there for their personalities, for keeping morale up, or maybe for some other brutally apparent reason that we won’t notice for another hundred years?
Maybe they’re just slackers.

Here’s the [Beef] Genome

The genomes of man and dog have been joined in the scientific barnyard by the genome of the cow, an animal that walked beside them on the march to modern civilization.
A team of hundreds of scientists working in more than a dozen countries yesterday published the entire DNA message — the genome — of an 8-year-old female Hereford living at an experimental farm in Montana.
Hidden in her roughly 22,000 genes are hints of how natural selection sculpted the bovine body and personality over the past 60 million years, and how man greatly enhanced the job over the past 10,000.
As with other species, genes governing the immune system, the metabolism of nutrients and social interaction appear to be where much of the evolutionary action has occurred. The result is an animal that lives peacefully in herds and grows large on low-quality food, thanks to the billions of bacteria it carries around.
Selective breeding has exaggerated and spread some of those traits, producing hyper-passive Holsteins and muscle-bound Belgian Blues, and dozens of humpbacked breeds that combine characteristics of both.
Raise your hand if…
…you need to want more.

One thing a recession is good for is reminding us how much we need.
Raise your hand if you’ve been doing a lot of talking about the economy and the lack of growth and the rise of unemployment and the worry and the poor attitudes and the general malaise about productivity in the global markets [insert image of me raising my hand]
It’s clear those of us living in the States have huge appetites and tendencies to need to want more and more and more.
What’s the matter with “Good” that we blindly and zealously trade it for “Better” no matter what the cost? Surely there’s a time and place for that, but sometimes perhaps we should just hang back and enjoy really GOOD?

Catalan

From Wikipedia:
The Catalans are the people from Catalonia, an Autonomous Community of Spain, including people originating in that region but living elsewhere. The inhabitants of the adjacent portion of southern France – known in Catalonia proper as Catalunya Nord (Northern Catalonia), and in France as the Pays Catalan – are often included in this definition.
However, it should be noted that for the majority of Catalans, a sense of Catalan identity is not viewed as being mutually exclusive with the Spanish one; a large majority of people feel both Catalan and Spanish. Comparable examples exist in other large European states with strong regional identities, such as Bavaria within Germany and Sicily within Italy. In contrast, the situation in France has been sharply different as French policies have favored the assimilation of Catalans. This has reduced the number of citizens who identify themselves as such within the French Republic, which has sought to make all within France feel French exclusively since its very inception.
