Snail Sex Study Funded With Your Tax Dollars
(CNSNews.com) –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.
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 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.
"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."
