Genomic techniques facilitate discovery that gene expression causes disparity

Although they live in similarly extreme ecosystems at opposite ends of the world, Antarctic insects appear to employ entirely different methods at the genetic level to cope with extremely dry conditions than their counterparts that live north of the Arctic Circle, according to National Science Foundation- (NSF) funded researchers.

Writing in the Proceedings of the National Academy of Sciences, the researchers concluded, “Polar arthropods have developed distinct… mechanisms to cope with similar desiccating conditions.” (more…)
