根据文献中的数据，计算了西欧、土耳其、北美（墨西哥以北）和日本的右旋蜗牛与左旋蜗牛的百分比。当有Closiliidae科的代表时，所有蜗牛物种中大约有四分之一可能是左旋的，而在没有该科的地方，只有不到1%的物种可能是左旋的。单基因物种形成事件的手性的基础上，导致镜像物种的起源，是没有密切联系的百分比，在一个特定的区域的左旋与右旋物种。然而，土耳其是例外的高比例的左旋物种和大量的物种形成事件导致镜像物种。壳形态和遗传背景可能会影响手性相关的物种形成的难易程度，而左旋性可能会另外通过内部选择进行选择。对于Closiliidae，化石记录和最近的动物群表明，成功的逆转盘绕方向发生的频率为每三到四百万年一次。
On the basis of data in the literature, the percentages of dextral versus sinistral species of snails have been calculated for western Europe, Turkey, North America (north of Mexico), and Japan. When the family of Clausiliidae is represented, about a quarter of all snail species may be sinistral, whereas less than one per cent of the species may be sinistral where that family does not occur. The number of single-gene speciation events on the basis of chirality, resulting in the origin of mirror image species, is not closely linked to the percentage of sinistral versus dextral species in a particular region. Turkey is nevertheless exceptional by both a high percentage of sinistral species and a high number of speciation events resulting in mirror image species. Shell morphology and genetic background may influence the ease of chirality-linked speciation, whereas sinistrality may additionally be selected against by internal selection. For the Clausiliidae, the fossil record and the recent fauna suggest that successful reversals in coiling direction occurred with a frequency of once every three to four million years.
