The reconstruction of evolutionary relationships among species is fundamental for our understanding of biodiversity. Today, evolutionary relationships are closely related with the depiction of the tree of life, and research on the topic is underpinned by methods in molecular phylogenetics that have grown in popularity since the 1960s. These methods depend on our understanding of how nucleotide or amino acid sequences evolve through time and in different lineages. Armed with this knowledge, researchers can make inferences about the relationships and amount of genomic divergence among species.
重建物种间的进化关系对于我们理解生物多样性至关重要。如今,进化关系与生命之树的描绘密切相关,自 20 世纪 60 年代以来,分子系统发生学方法的普及为该领域的研究提供了支持。这些方法依赖于我们对核苷酸或氨基酸序列随时间和不同谱系进化的理解。有了这些知识,研究人员就可以推断物种之间的关系和基因组分歧的程度。
