请提取文中与 phylogenetic tree 构建方法有关的信息，并在4句话内总结。 nurture or nature – probing the core of CRISPR archaea：ACTER8 – A plasmid/prophages figsize phylogenetic evidence and cas1 sequence-based stories reveal the evolutionary path Capac upper add two or progenitor impact action from crassvirales supergroup Archaea to their convergent recurring theme deriving from a primordial. Therefore, this suggests that the derived and progenitor impact action had a significant role in its evolution. The evolution ofål wide-ranging impact on modern archaea, such as their ability to combat intense viral wides attacks. Additionally, novel CRISPR-Cas systems identified give renewed insights into horizontal gene transfer among modern archaea. Phylogenetic analysis of Cas1 and the global supermatrix is crucial in unveiling the detailed origins and diversification mechanisms of these microbial defense systems. Because it not only supports the derived subtype but also potentially refutes those having the conflicting aspects of cas1 nucleotide evolution as the primary factor, providing a comprehensive map of the evolutionary events emphasizing the active and constant horizontal gene transfer (HGT) dynamics within and across different archaea lineages.

文中提到，通过 Cas1 序列和全球超矩阵的系统发育分析，揭示了微生物防御系统的起源和多样化机制。这些分析不仅支持衍生亚型，还可能反驳以 cas1 核苷酸进化为主要因素的观点。此外，这种分析提供了全面的进化事件图谱，强调了不同古菌谱系内及之间的活跃和持续的水平基因转移（HGT）动态。新发现的 CRISPR-Cas 系统为理解古菌间的水平基因转移提供了新的见解。
