The origin of the directed motion of protocells during the early stages of evolution was discussed. The expenditures for movement, space orientation, and reception of information about the environment were taken into consideration, and it was shown that directed movement is evolutionarily advantageous in the following cases: when opposite gradients of different resources (for example, matter and energy) are great enough and when there is a rapid change in environmental parameters. It was also shown that the advantage of directed movement strategies depends greatly on how information about the environment is obtained by a protocell.
探讨了原生细胞在进化早期定向运动的起源。考虑了运动、空间定向和接收环境信息的支出，并表明在以下情况下，定向运动在进化上是有利的：当不同资源（例如物质和能量）的相反梯度足够大，并且环境参数发生快速变化时。还表明，定向运动策略的优势在很大程度上取决于原生细胞如何获取环境信息。
