Journal ArticleDOI
Dating of the human-ape splitting by a molecular clock of mitochondrial DNA.
TL;DR: A new statistical method for estimating divergence dates of species from DNA sequence data by a molecular clock approach is developed, and this dating may pose a problem for the widely believed hypothesis that the bipedal creatureAustralopithecus afarensis, which lived some 3.7 million years ago, was ancestral to man and evolved after the human-ape splitting.
Journal ArticleDOI
Phylogenetic relationships among eukaryotic kingdoms inferred from ribosomal RNA sequences.
TL;DR: In the maximum-likelihood trees for both large- and small-subunit rRNAs, Animalia and Fungi were the most closely related eukaryotic kingdoms, and Plantae is the nextmost closely related kingdom, although other branching orders among Plantae, AnimalIA, and F Bungi were not excluded by this work.
Journal ArticleDOI
Man's place in Hominoidea as inferred from molecular clocks of DNA.
TL;DR: The ratio of the dates of orangutan splitting to chimpanzee is larger for the mtDNA clock than that for the η-globin clock, suggesting the possibilities of mt-DNA introgression among the early hominids and the early African apes, and/or of mtDNA polymorphism within the common ancestral species of Orangutan and the African apes that obscures the date of the true species separation ofOrangutans.
Journal ArticleDOI
Estimation of branching dates among primates by molecular clocks of nuclear DNA which slowed down in Hominoidea
TL;DR: Estimated divergence dates from DNA sequence data suggest that human separated from the African apes about 4 ∼ 7 My ago.
Journal ArticleDOI
A New Molecular Clock of Mitochondrial DNA and the Evolution of Hominoids
TL;DR: The molecular clock, however, is not yet free of any contradiction with hominoid fossil records, and a direct comparison among mitochondrial DNA sequences shows a recent divergence of 4-& million years (Myr) ago.
