Bajo un enfoque filogenético, los datos morfométricos también se pueden usar para el estudio de la variación de caracteres taxonómicos, la identidad de los estados y la inferencia de filogenias. Los grupos taxonómicos debieran ser propuestos a partir de grupos monofiléticos descubiertos con métodos filogenéticos. Resultados clave: Se presentan las bases de ysstematics teoría de la morfometría, geometría vectorial, el espacio de Kendall, la distancia Procrustes, proyección de espacios tangenciales y construcción de hipercubos del morfoespacio.

The Diagnosis. Mess definition synonyms theory defines the inclusive fitness of an organism as the sum of its classical fitness how many of its own offspring it produces and supports and the number of equivalents of its own offspring it can add to the population by supporting others. Mutation creates new alleles. Variation disappears when a new allele reaches the point of fixationwhen it either disappears from the population or replaces the ancestral allele entirely. An example is the wings of insects and birds. At certain points in time, phylognetic individual in a species begins to exhibit a new phase of growth that advances all to the form of a new species.

It is also related to taxonomywhich is a branch of science concerned also in finding, describing, classifying, and naming organisms, including the studying of the relationships between taxa and the principles underlying such a classification. Phylogenetic Species Concepts.
