Population effects of chiral snail shell development relate handedness to health and disease

The spiral patterns of snail shells exhibit chirality, or “handedness.” These often heavily favor the dextral (right-handed, clockwise) over sinistral (left-handed, phenotype. While developmental pathways resulting in each enantiomorph (non-superimposable mirror image form) have been studied extensively, there has limited investigation into how emphasis on one direction other may confer survival benefit. This perspective essay proposes that events determining cell cleavage robustness, mating compatibility, and predator evasion can influence distribution snails. connection between chirality survivability broader implications for exploring role handedness diseases their treatments.
