Biomimetic morphologies constructed in pure inorganic systems, called biomorphs, provide a promising approach to produce advanced biomimetic materials via bottom-up self-organization. Although existing biomorphs show the potential to imitate complex and/or hierarchical micro-architectures, they can only be achieved by changing the conditions manually during the reaction, not an intelligent morphological self-evolution. In this contribution, we propose a strategy to introduce more than one type of initial variable for the construction of different formation/transition pathways to realize a hierarchical architecture via self-evolution. A hierarchical architecture with unique triangular branches was obtained successfully by initial control of both the temperature and Mg²⁺ doping, highlighting two pathways for the textured growth of polycrystals and single crystals in different hierarchies led by CO₂ and MgCO₃, respectively. Our findings lay the foundation for the future construction of materials with new complex hierarchical architectures via a self-evolution approach realized by rational pathway design.

生物形态三角剖分：构建一条额外的形成途径，以实现生物形态的分层自进化

在纯无机系统中构建的仿生形态称为生物形态，为通过自下而上的自组织生产先进的仿生材料提供了一种有前途的方法。尽管现有的生物形态显示出模仿复杂和/或分层的微结构的潜力，但只能通过在反应过程中手动更改条件来实现，而不是智能的形态自进化。在此贡献中，我们提出一种策略，引入一种以上类型的初始变量以构建不同的形成/过渡路径，从而通过自进化实现层次结构。通过对温度和Mg ^2+的初始控制，成功获得了具有独特三角分支的分层体系结构掺杂，突出了分别由CO ₂和MgCO ₃导致的不同层次中多晶和单晶的织构生长的两条途径。我们的发现奠定了与新的复杂的分级结构材料的未来建设的基础上通过通过合理的途径设计实现了自我进化的方法。
