If a common ancestor of all living humans is defined as an individual who is a genealogical ancestor of all present-day people, the most recent common ancestor (MRCA) for a randomly mating population would have lived in the very recent past. However, the random mating model ignores essential aspects of population substructure, such as the tendency of individuals to choose mates from the same social group, and the relative isolation of geographically separated groups. Here we show that recent… 
Common Ancestors in a Generalized Moran model
TLDR
This paper introduces a generalized version of the Moran model such that, with a probability 1− p, the new individual will have two parents, inspired by a two-parent versions of the Wright–Fisher model.
Genealogy and gene trees.
TLDR
Demographic processes are incorporated in the model, but since culture and customs are known to influence demography the models used ought to be tested against available genealogy and the Icelandic data base offers a possibility to do so and points to some discrepancies.

TLDR
This analysis demonstrates that it is possible to rebuild the tree of progenitors by modeling the problem with a Markov chain by introducing the invariance under a gauge (local) group of dilations.
A genetic perspective on human origins
TLDR
The possibility to assess genetic information from thousands of individuals across the world and to obtain DNA from specimens that lived thousands of years in the past (so-called ancient DNA [aDNA] analyses) is rapidly transforming long-held beliefs about the authors' origins.
Modeling the contrasting Neolithic male lineage expansions in Europe and Africa
TLDR
Although highly simplified, the demographic model used captures key elements of the differences between the male Neolithic expansions in Africa and Europe, and is consistent with archaeological findings.
Frontiers in Coalescent Theory: Pedigrees, Identity-by-Descent, and Sequentially Markov Coalescent Models
TLDR
This dissertation develops a coalescent hidden Markov model approach to inferring the demographic and reproductive history of a triploid asexual lineage derived from a diploid sexual ancestor of the New Zealand snail Potamopyrgus antipodarum.

Recent common ancestors of all present-day individuals
TLDR
This work studies a two-parent analog of the Wright-Fisher model that defines ancestry using both parents, and finds that all partial ancestry of the current population ends, in the following sense: with high probability for large n, in each generation at least 1.77 lgn generations before the present.
On the genealogy of a population of biparental individuals.
TLDR
It is shown that the distribution of the repetitions of ancestors reaches a stationary shape after a small number G( c) approximately log N of generations in the past, that only about 80% of the ancestral population belongs to the tree (due to coalescence of branches), and that two trees for individuals in the same population become identical after G(c)generations have elapsed.
Recent common ancestry of human Y chromosomes: evidence from DNA sequence data.
TLDR
It is estimated that the spread of Y chromosomes out of Africa is much more recent than previously was thought, and the data indicate substantial population growth in the effective number of human Y chromosomes.
Genealogy and subpopulation differentiation under various models of population structure
TLDR
It is seen that FST can depend strongly on the mutation rate, for example in the case of an essentially one-dimensional habitat with many subpopulations where gene flow is restricted to neighbouring subpopulation.
Archeology, population genetics and studies of human racial ancestry.
TLDR
It is shown that the probable demographic nature of Pleistocene populations has obscured genetic distances to such an extent that they cannot be used to discriminate between the two viewpoints of racial origins, so that the authors presently do not have a scientifically valid understanding ofracial origins.
On the number of ancestors to a DNA sequence.
TLDR
The distribution of ancestral material to an extant chromosome is here investigated by the coalescent with recombination, and the results are discussed relative to humans.
Anthropological Genetics of Small Populations
TLDR
The detailed analysis of human populations can provide perspective on assumptions and allow measurements of variables which would be difficult if not impossible to examine in natural populations of other organisms.
Mitochondrial genome variation and the origin of modern humans
TLDR
The global mtDNA diversity in humans is described based on analyses of the complete mtDNA sequence of 53 humans of diverse origins, providing a concurrent view on human evolution with respect to the age of modern humans.
Maternal and Paternal Lineages of the Samaritan Isolate: Mutation Rates and Time to Most Recent Common Male Ancestor
TLDR
The haplotypes identified in Samaritan paternal lineages that belong to the same haplogroup were used to estimate the number of generations elapsed since their most recent common ancestor (MRCA), and the estimate of 80 generations corresponds with accepted traditions of the origin of this sect.
