The species concept, thematic subject in natural sciences – the scientific approaches of Emil G. Racovitza and Nicolae Botnariuc

Abstract

EMIL G.RACOVITZA supported a Genealogic species concept, expressed as “a colony of isolated consanguines”. The RACOVITZA’s concept considers species as homogenous lineages of organisms which evolve during their history. Description of such entities requires the recognition of primitive and derived states of the morphologic traits
