Q.The term 'species' was introduced by:

Species is the fundamental unit of taxonomic classification, tracing back to Plato's 'eidos' and defined by Stebbins (1977) as the basic unit of the evolutionary process. A species is a group of organisms that closely resemble each other more than other populations, descend from a common ancestor, and (if sexual) interbreed freely producing fertile offspring in nature - or, for asexual/fossil organisms, are identified by morphological (and, for fossils, anatomical) resemblance alone. Species concepts split into two general groups: those built on the PROCESS of evolution (which maintains species as units and drives divergence/speciation) and those built on the PRODUCT of evolution. This yields three named species concepts. Morphological (Taxonomic) species groups individuals similar in one or more features and different from other such groups, defined with NO knowledge of phylogenetic history, gene flow or reproductive mechanisms - a purely observational, product-of-evolution concept. Biological (Isolation) species, per Ernst Mayr (1963), are 'groups of populations that interbreed and are reproductively isolated from other such groups in nature' - the cla …
