摘要: 本文对生命史中多细胞物种的形成机制提出了创新性的观点并对此进行论述。该新观点认为:生命进化的本质是各种生命生存效率优化的过程。在此过程中,多细胞物种的产生必然要解决一对矛盾,即单细胞局部利益最大化与多细胞整体利益之间的矛盾。解决这对矛盾是保证多细胞整体生存竞争效率的前提。因此,多细胞物种的进化必然是不断优化整体调控机制过程。调控机制的建立与完善是通过细胞的智能活动完成的。文章对多细胞物种的成种过程进行了逻辑推理,并依此推理过程提出了6个重要的预测,通过列举与这些预测相一致的事实证据来说明笔者该观点的合理性。

Abstract: In this article, new opinion on the evolutionary mechanism of multicelluarity was presented, i.e., the evolution of life was a process of efficiency optimization for survival. Therefore an inevitable conflict that between individual and overall interests within multicellularity was occured. This should be coordinated to assure the overall efficiency which hints that regulation were of ultimate importance. A suggestion that the emergence of regulation mechanism was evolved in an intelligence-based way. Hypot...
