WebStudies of mitochondrial DNA (mtDNA) suggest that the common ancestor of all modern humans lived approximately 200,000 years ago, implying that modern humans (Homo sapiens) arose in Africa (the out-of-Africa hypothesis). page 497 The mtDNA out-of-Africa pattern is supported by Y chromosome analysis, which also shows a recent African origin … WebThe information below was adapted from OpenStax Biology 23.1. There are many unique characteristics of eukaryotes that allow us to distinguish them as a monophyletic group on the phylogenetic tree of life. The following characteristics must have been present in the last common ancestor (LCA) from which all eukaryotic life emerged:
