Elucidating the evolutionary origins of social behavior remains a major challenge due to the complexity of social systems across taxa. Here, we examine social behavior through the lens of competition and cooperation across the three domains of life-, and . By focusing on gene-based mechanisms, we propose that sociality arises from conserved molecular pathways shaped by similar selective pressures, even in phylogenetically distant organisms. This cross-domain perspective highlights the potential for convergent evolutionary solutions and offers a foundation for identifying invariant principles underlying the emergence and maintenance of social behavior.
由于不同分类群中社会系统的复杂性，阐明社会行为的进化起源仍然是一项重大挑战。在这里，我们从生命的三个领域（细菌、古菌和真核生物）的竞争与合作角度来研究社会行为。通过关注基于基因的机制，我们提出，即使在系统发育上相距甚远的生物体中，社会性也源于由相似选择压力塑造的保守分子途径。这种跨领域的观点突出了趋同进化解决方案的潜力，并为确定社会行为出现和维持的不变原则提供了基础。
