Abstract
Evolutionary lineages are, either Darwinian populations, or monophyletic group composed of Darwinian populations, or demes, that are derived from a foundational Darwinian population, or from a portion of a Darwinian population. That these populations, and portions of populations, are considered as demes implies that they can register microevolutionary processes such as natural selection, sexual selection, genetic drift, migration and genetic mutation. The derivation that goes from an ancestral population to a population that originates from it, is something real; because the individuals of the initial stock of the derived population have material links of filiation with the individuals of the primitive population. Los linajes evolutivos son poblaciones darwinianas o grupos monofiléticos compuestos de poblaciones darwinianas, o demes, que se derivan de una población darwiniana fundacional o de la fracción de una población darwiniana. El hecho de que esas poblaciones y fracciones de poblaciones sean consideradas como demes implica que en ellas puedan registrarse procesos microevolutivos tales como selección natural, selección sexual, deriva genética, migración y mutaciones genéticas. La derivación que va de una población ancestral a una población que de ella se origine es algo real, porque los individuos del stock inicial de la población derivada guardan vínculos de filiación con los individuos de la población primitiva.Keywords
