Feds Spending $880,000 to Study Benefits of Snail Sex
The National Science Foundation has given a grant that could wind up totaling almost a million dollars to a University of Iowa study researching which is better for New Zealand mud snails: reproducing sexually or asexually. The grant (your tax dollars or future debt), awarded in 2011 to last until 2015, has already cost $502,357, and could wind up costing taxpayers $876,752 before all is said and done. But there is no money for White House tours and military support of Air Shows are grounded. CNS News has the story below.
By Matt Cover, CNS News: The National Science Foundation awarded a grant for $876,752 to the University of Iowa to study whether there is any benefit to sex among New Zealand mud snails and whether that explains why any organism has sex.
The study, first funded in 2011 and continuing until 2015, will study the New Zealand snails to see if it is better that they reproduce sexually or asexually – the snail can do both – hoping to gain insight on why so many organisms practice sexual reproduction.
“Sexual reproduction is more costly than asexual reproduction, yet nearly all organisms reproduce sexually at least some of the time. Why is sexual reproduction so common despite its costs,” the study’s abstract asks.
“This project will use a different organism, Potamopyrgus antipodarum, a New Zealand snail, which has both sexual and independently-derived asexual lineages that make it ideally suited to address fundamental evolutionary questions of how genes and genomes evolve in the absence of sexual reproduction.”
In other words, the study seeks to see if there are genetic advantages to sexual reproduction that justify its evolutionary costs, advantages such as avoiding genetic mutations or gene loss.
So far, the grant has paid out $502,357, according to NSF, and could pay out the full $880,000 between now and 2015. The study is funded through what NSF calls a continuing grant meaning that it agrees with the researcher to fund a certain amount, but can end up spending more on the grant if NSF agrees that more money is warranted.
The broader aim of the study is to find out why sexual reproduction and males exist, arguing that sex is biologically inefficient for females. Because an asexual organism can simply clone itself faster than it can reproduce if it finds a mate, the study seeks to see if there are other benefits to sexual reproduction that outweigh this ‘cost’ of finding a mate.
In a University of Iowa press release announcing the grant, this is described as the “cost of males” – explaining that female organisms shouldn’t need to produce sons instead of daughters because producing daughters simply involves asexual duplication – which can then duplicate themselves – while male offspring cannot produce other male offspring unaided.
“[T]he commonness of sex is surprising because asexual females should be able to produce twice as many daughters as sexual females that make both male and female offspring,” the release says.
“Despite this and other costs, nearly all organisms reproduce sexually at least some of the time. This means that sex must be associated with profound advantages, while asexual reproduction must have significant evolutionary consequences.”

What, are snail becoming extinct? Oh, I forgot, not enough escargot at the 'Last Obama Supper.'
LOL at your comment Ron. But can't laugh at the wasted federal spending.
