摘要: This paper evaluates the relationship between strategy of genome evolution and robustness DNA hybridizations data. Birds primates differ significantly from Drosophila, plants Cladophora in ratio NPH to ΔTme values. difference is discussed an evolutionary molecular perspective. We conclude that intensity frequency processes (such as turnover) not only hamper ability infer phylogenetic relationships, but also estimate time divergence In second section this paper, single copy West European isolates four species: C. sericea, albida, pellucida vagabunda was hybridized with conspecific Atlantic (in case a related species, pellucidoidea). The high levels similarity found cold-temperate North region are interpreted resulting disruption biogeographic patterns during glacial periods re-establishment same or comparable interglacial periods. At lower latitudes, amphi-Atlantic show more divergence. Thermal isolation warm-temperate East regions may date middle Miocene onwards. effectiveness central dispersal barrier thought vary both function adaptive plasticity species concerned environmental changes over time.
