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.
