摘要: How the cilium appeared is still such a poorly defined question that current hypotheses range from symbiotic spirochaete to cellular eye. In this paper, whole subdivided into list of problems which are morphological, physiological and temporal. These examined one by one, in order analyse most popular exogenous hypothesis Margulis as well other recent endogenous hypotheses. To overcome fundamental topological temporal difficulties, new expounded, according derives peduncle reinforced with microtubules. This implies geometrical rationale for ninefold symmetry. last paragraph consequences various compared.
