Morphometrics
Morphometrics (from Greek ''μορϕή'' "morphé", meaning 'shape' or 'form', and ''μετρία'' "metría”, meaning 'measurement') or morphometry 〔http://www.oed.com/view/Entry/122372?redirectedFrom=morphometrics#eid〕 refers to the quantitative analysis of ''form'', a concept that encompasses size and shape. Morphometric analyses are commonly performed on organisms, and are useful in analyzing their fossil record, the impact of mutations on shape, developmental changes in form, covariances between ecological factors and shape, as well for estimating quantitative-genetic parameters of shape. Morphometrics can be used to quantify a trait of evolutionary significance, and by detecting changes in the shape, deduce something of their ontogeny, function or evolutionary relationships. A major objective of morphometrics is to statistically test hypotheses about the factors that affect shape.
"Morphometrics", in the broader sense of the term, is also used to precisely locate certain areas of organs such as the brain, and is used in describing the shapes of other things.
==Forms of morphometrics==
Three general approaches to form are usually distinguished: traditional morphometrics, landmark-based morphometrics and outline-based morphometrics.
