The retrieved evidence partially provides dates for individual ancestral lineages such as Mitochondrial Eve and Y-chromosomal Adam across separate sources, but none jointly establish the relative chronological comparison asserted by the claim.
Mitochondrial DNAs from 147 people, drawn from five geographic populations have been analysed by restriction mapping. All these mitochondrial DNAs stem from one woman who is postulated to have lived about 200,000 years ago, probably in Africa. All the populations examined except the African population have multiple origins, implying that each area was colonised repeatedly.

The proposal that all mitochondrial DNA (mtDNA) types in contemporary humans stem from a common ancestor present in an African population some 200,000 years ago has attracted much attention. To study this proposal further, two hypervariable segments of mtDNA were sequenced from 189 people of diverse geographic origin, including 121 native Africans. Geographic specificity was observed in that identical mtDNA types are shared within but not between populations. A tree relating these mtDNA sequences to one another and to a chimpanzee sequence has many deep branches leading exclusively to African mtDNAs. An African origin for human mtDNA is supported by two statistical tests. With the use of the chimpanzee and human sequences to calibrate the rate of mtDNA evolution, the age of the common human mtDNA ancestor is placed between 166,000 and 249,000 years. These results thus support and extend the African origin hypothesis of human mtDNA evolution.
It is commonly thought that human genetic diversity in non-African populations was shaped primarily by an out-of-Africa dispersal 50-100 thousand yr ago (kya). Here, we present a study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples. Applying ancient DNA calibration, we date the Y-chromosomal most recent common ancestor (MRCA) in Africa at 254 (95% CI 192-307) kya and detect a cluster of major non-African founder haplogroups in a narrow time interval at 47-52 kya, consistent with a rapid initial colonization model of Eurasia and Oceania after the out-of-Africa bottleneck. In contrast to demographic reconstructions based on mtDNA, we infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky. We hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.

Phylogenetic analyses Summary statistics, such as nucleotide diversity, mean pairwise differences, and AMOVA, were computed in Arlequin v3.5.1.3 ( Excoffier and Lischer 2010 ). We used software package BEAST v1.8.0 ( Drummond et al. 2012 ) to reconstruct phylogenetic trees, estimate coalescent ages of haplogroups, and sex-specific effective population sizes. The general time reversible (GTR) substitution model was selected by jModelTest ( Darriba et al. 2012 ) as the best fit for the Chr Y data and the HKY + I + G for the mitochondrial genomes. In order to reduce the computational load, the Chr Y BEAST analysis only contained the variable positions.
