我们提出了一种方法学系统发育重建方法相结合的最大简约和系统发生网络方法适用于人类进化的研究22种人类的表型颅齿特征。该方法包括在选择和验证一个树状最简约的情况下，几个简约运行的基础上，各种数值约束。从树到网络方法的中间步骤是通过使用生成多个简约树的简化类形字符数据集运行分析来实现的。这些最简约的树然后被用作系统发生网络分析的输入，导致共识和网状网络。我们在这里表明，属人的系统发育树的定义是一个相对的概念，与颅齿特征，来支持假设的最后共同祖先的最吝啬的情况下，并推断人网状网络与最近的研究结果在古基因组学的进化模式相一致。将最大简约法和系统发生网络法结合起来研究人类进化最简约的树状情景显示了3种可供选择的属人定义我们认为同源逆转在人类进化中起着重要作用系统发生网络分析显示了属人可能的网状进化模式生物科学;进化生物学;系统发生学
We present a methodological phylogenetic reconstruction approach combining Maximum Parsimony and Phylogenetic Networks methods for the study of human evolution applied to phenotypic craniodental characters of 22 hominin species. The approach consists in selecting and validating a tree-like most parsimonious scenario out of several parsimony runs based on various numerical constraints. An intermediate step from tree to network methods is implemented by running an analysis with a reduced apomorphous character dataset that generates multiple parsimonious trees. These most parsimonious trees are then used as input for a Phylogenetic Networks analysis that results in consensus and reticulate networks. We show here that the phylogenetic tree-like definition of the genus Homo is a relative concept linked to craniodental characters that come in support of hypothetical Last Common Ancestors of the most parsimonious scenario and infer that the Homo reticulate network concords with recent findings in paleogenomic research regarding its mode of evolution. Integrate Maximum Parsimony and Phylogenetic Networks methods in study of human evolution Most parsimonious tree-like scenario shows 3 alternative genus Homo definitions We suggest that homoplastic reversals play an important role in human evolution Phylogenetic Networks analysis shows probable reticulate mode of evolution in genus Homo Biological Sciences; Evolutionary Biology; Phylogenetics
