The volar surface of hands and feet display an array of diagnostic features that exhibit both macroscopic and microscopic morphometric attributes. The macroscopic attributes are typically developmentally stable in the human population, which means these features can be exploited to determine which part of the hand or foot is represented in an impression and the distal orientation of an impression. The microscopic attributes are often subject to stochastic effects during embryological development or acquisition after birth. As a result, these smaller features can be combined with the macroscopic features to determine the ultimate utility of an impression and support source conclusions. Although the diagnosticity of each macroscopic and microscopic feature has theoretical constraints based on the influence of developmental stability and developmental noise, there are also biological constraints to the longevity of each feature and sources of distortion that affect the recording of the features in an impression. This article sheds light on the various features of the friction ridge skin, the attributes of each feature, the expected usefulness of these features for establishing search parameters, the expected usefulness in establishing identity, and common sources of variation in appearance of each feature. This article also illuminates areas where additional research would benefit the friction ridge community.
