Research Abstract |
This study threw a light on the role of the aperture map, or pattern of relative rate of shell accretion for each point around the shell margin, in relation to morphological diversity of molluscan shells. This study provides some evidences of a sort of developmental constraint on the range of shell form which can be attributed to regulation of the aperture map. Further analysis may help us understand which kinds of morphological evolution of the molluscan shell are achieved readily or with difficulty ; this is an exciting subject for future research.
