AI Insight
Scientists from the University of Nottingham and Tohoku University have identified a specific gene that controls whether Japanese Euhadra snails develop shells that coil to the right or to the left. This discovery explains the molecular mechanism behind chirality (mirror-image asymmetry) in snail shell development. The research involved studying wild snail populations in Japan to determine the genetic basis for this directional coiling pattern.
Why it matters
This finding has broader implications beyond snail biology, as it may help scientists better understand the fundamental mechanisms that determine left-right asymmetry in living organisms, including the arrangement of internal organs in humans and other animals.
Understand the Science
Scientists have discovered a gene that determines whether Japanese snails develop shells that are left- or right-coiling—with implications for understanding the underlying handedness of our own bodies. The researchers from the University of Nottingham and Tohoku University studied wild Euhadra snails in Japan to understand what makes one snail a mirror image of another.
