WebGeometric Morphometrics and SHAPE analysis were developed to investigate morphological variations of an organisms. Existing studies convinced that morphometrics can measure a character of evolutionary importance and their ontogeny or evolutionary relationship by identifying the difference in the shape of organisms. WebMorphometrics can be used to quantify a trait of evolutionary significance, and by detecting changes in the shape, deduce something of their ontogeny, function or …
