Apparently, the evolution have generated the situation of the separation of monosyllabic form and disyllabic form, and thus generated the form system of direction words. The totally different paralleling dual system is the basis of the later evolution. The monosyllabic and disyllabic direction words has gradually come into the weakened meaning or morpheme,while disyllabic direction words has more substantive nature,with more freedom in the sentences.

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.
