The following summaries describe some published research results. Research 1. Wu and Li (1985): The comparative analysis of homologous genes between human and mouse genomes suggests that the evolutionary rate of homologous genes was higher in the mouse lineage than in the human lineage. Research 2. Smith and Donohe (2008) : The plant families Caprifoliacease, Asclepiadeceae and Lamiaceae are compsed of both herbaceous and arborescent speciers. The comparative analysis of homologous genes between the herbaceous and arborescent species within a single plant family suggests that the evolutionary rate of homologous genes in herbaceous lineages were faster than of arborescent lineages in all three plant familes. Research 3. Gilman et al. (2009): The comparative analysis of 130 homologous mitochondrial genes between a sister species pair of vertebrates from the temperate region and from the tropical region indicate that the base substitution rates of homologous genes from the tropical region are 1.7 times faster than that of the temperate region. Based on these studies which of the following statements best describes the common evolutionary processes in plant and animal genes?
