| 摘 要： | 生物进化通常呈现出从简单到复杂的进化趋势,即在地球上越晚出现的生物其结构越复杂。该研究揭示了由于生物在从同一个进化平台上演化生成的生物中,结构趋向复杂的部分所占比例远远大于结构趋向简单的部分所占比例,即不对称进化,从而导致了生物界从简单到复杂的进化趋势;还解释了不对称进化形成的原因,并列举了有关生物不对称进化的许多重要证据。

| Abstract: | The evolutionary trend of organisms, which often evolved from a simpler structure to a more complex structure, is a mystery. It seems that the later living things appeared on the earth, the more complex their structures were. This study pointed out that the evolutionary trend of organisms was the result of the organisms＇ asymmetric evolution-the phenomenon which the partition of the more complex structure was actually larger than that of the simpler structure on the same evolutionary platform of organisms, it explained the cause of the asymmetric evolution and listed much important evidence for organisms＇ asymmetric evolution. |
