Morphometrics is the study of the shape and size of organisms and their features. It involves measuring and analyzing the physical characteristics of biological forms, such as plants, animals, and humans. Researchers use various techniques, including geometric and statistical methods, to understand how these shapes vary among different species or populations. This field is important in areas like evolutionary biology, where scientists explore how shape changes relate to adaptation and evolution. Morphometrics can also aid in conservation biology by helping to identify species and assess their health based on morphological traits.
