In order to understand the evolution of multicellularity, we must understand how and why selection favors the first steps in this process: the evolution of simple multicellular groups. Multicellularity has evolved many times in independent lineages with fundamentally different ecologies, yet no work has yet systematically examined these diverse selective drivers. Here we review recent developments in systematics, comparative biology, paleontology, synthetic biology, theory, and experimental evolution, highlighting ten selective drivers of simple multicellularity. Our survey highlights the many ecological opportunities available for simple multicellularity, and stresses the need for additional work examining how these first steps impact the subsequent evolution of complex multicellularity.
为了理解多细胞生物的进化，我们必须了解选择是如何以及为何有利于这一过程的最初步骤：简单多细胞群体的进化。多细胞生物已经在具有根本不同生态的独立谱系中多次进化，但还没有人系统地研究过这些不同的选择驱动因素。在这里，我们回顾了系统学、比较生物学、古生物学、合成生物学、理论和实验进化方面的最新进展，强调了简单多细胞生物的十个选择驱动因素。我们的调查强调了简单多细胞生物可获得的许多生态机会，并强调需要进一步研究这些最初步骤如何影响复杂多细胞生物的后续进化。
