For nearly half a century, both debates have been marked by the prominent role of the genetic level. Un simple método comparativo dentro de la no-paramétrico de la distribución se ha propuesto, 1 entre dos muestras de la misma especie y 2 de dos especies diferentes, con advantaegs en los conceptos de normal y la variación en la anatomía y de la clase modal en estadísticas aquí llamado Índice Anatomíca Comparada IAC. Cortex, phylogenrtic 8 Lindbergia Search in Google Scholar. A simple comparative method within the non-parametric distribution has been proposed, 1 between two different samples from the same species and 2 for two different species, based on the concepts of normal and variation in anatomy and on modal class in statistics here called Comparative Anatomy Index IAC. We now begin to recognize the importance of other ontological and causal levels along the biological hierarchy. Language: ENG. Ungerer Slecies.

En el plano conceptual y en el ontológico. Respecto del primero, se han analizado las ventajas y desventajas de diversos conceptos de especie biológico, fenético, ecológico, filogenético…. Ambos debates has estado marcados durante casi medio siglo por el puesto central que ocupaba el nivel genético. Comenzamos ahora a reconocer la importancia ontológica y causal de otros niveles de la jerarquía biológica. Estimamos probable que tengamos advantages and disadvantages of phylogenetic species concept convivir indefinidamente con una pluralidad de conceptos de especies.

Regarding the former, the biologists have analyzed the advantages and disadvantages of various concepts of species biological, phenetic, ecological, phylogenetic In the ontological realm, biologists and philosophers have discussed whether species cobcept classes, individuals or some other entity. For nearly half a century, both debates have been marked by the prominent role of the genetic level.

With the extension of the biological synthesis produced in phylogenehic last two decades, the gene begins to lose its privileged place as cause and explanation of every biological phenomenon. We now begin to recognize the importance of other how to show increase or decrease between two numbers in excel and causal levels along the biological hierarchy.

We think that this change of perspective will affect the debate on advantages and disadvantages of phylogenetic species concept notion of species, both in the conceptual and ontological realms. We are not yet able to offer definitive conclusions, but we will shine a light on the future direction of the debate on the notion of species. We estimate that we have probably to live indefinitely with a plurality of concepts of species.

And, regarding the ontological plane, we would propose a non-homogeneous pluralism. Probably we will be forced to recognize causal force and ontological weight to entities of various levels, from the gene to the ecosystem, possibly including species, although not according the same weight to each one.

Therefore, if more distant species are considered, and since the comparison of the coracobrachialis muscle in Cebus and other species in which the origin, insertion and vascularization of the muscle in these animals is different in relation to Cebuswe must define RF parameters of 1 for Cebus and the different parameters in other species as 0, hence, the MPFii for this species advantages and disadvantages of phylogenetic species concept 0. When more than one parameter location, nerve, blood vessel, origin and insertion of a muscle, for example is considered, fact that should be considered in a more complete anatomical study, the Weighted Average of Frequencies MPF is carried out, generating specific weights according to the relevance degree of parameters to be considered, having as basis the aspects of less variation within these parameters, for example, the innervation of structures advantages and disadvantages of phylogenetic species concept the parameter of smallest variation, both for the same species and for different and close species.
