四足动物进化过程中的躯体拓扑稳定性

The Stability of the Body's Topological Form of Quadruped in the Evolution

通过对四足动物躯体拓扑结构的分析比较,结果表明,四足动物躯体的拓扑形态在进化上具有高度稳定性,这种稳定性的具体原因尚不得而知,但可以肯定,控制四足动物躯体拓扑形态的基因在进化上也具有高度稳定性。分析认为,稳定性并不是来自于选择,而是出于生物基因内部的某种原因;并不是躯体拓扑形态发生了变化而被选择所淘汰,而是变化根本就没有发生,或者发生了却不稳定。

rlhmngh the analysis on the structure of topological form of quadruped body, the high stability of topological form of quadruped body during evolution was found. the reason of the high stability was still unknown, but it was affirmed that the genes of topological form of quadruped body had high stability during evolution. It was considered that the stability of topological form of quadruped body was not from natural choice but from some masons caused within biological genes, It was not eliminated through choice in changes of body topological form, but the changes never happen at an, or it happened but it couldn＇ t be inherited ＇by offspring.
