Abstract: | Historical opinions of the “species problem” are briefly reviewed, and four salient stages are recognized according to origin
of species concepts. We propose that species is the unit preserving superior gene assembly and is maintained by specific mechanisms.
Based on characteristics of plant evolution, we assume that understanding plant species may include three stages, i.e. morphological
recognition stage, multidisciplinary verification stage, and illuminating mechanisms preserving superior gene assembly. |
