Timing of ancient human Y lineage depends on the mutation rate: A comment on Mendez et al

TLDR
The identification of a Y chromosome lineage from an African American that is an outgroup to all other known Y haplotypes, and a time to most recent common ancestor, TMRCA, for human Y lineages that is substantially longer than any previous estimate, are reported.

The ‘extremely ancient’ chromosome that isn’t: a forensic bioinformatic investigation of Albert Perry’s X-degenerate portion of the Y chromosome

TLDR
The analysis indicates that the A00 lineage was derived from all the other lineages 208 300 (95% CI=163 900–260 200) years ago, and raises two astonishing possibilities, either the novel Y chromosome was inherited after ancestral humans interbred with another species, or anatomically modern Homo sapiens emerged earlier than previously estimated and quickly became subdivided into genetically differentiated subpopulations.

The Divergence of Neandertal and Modern Human Y Chromosomes

A Rare Deep-Rooting D0 African Y-Chromosomal Haplogroup and Its Implications for the Expansion of Modern Humans Out of Africa

TLDR
This work resolves a long-running debate about Y-chromosomal out-of-Africa/back-to-Afrika migrations, and provides insights into the out- of-Af Africa expansion more generally.

Refining the Y chromosome phylogeny with southern African sequences

TLDR
Over 900 kb of Y chromosome sequence obtained from 547 individuals from southern African Khoisan- and Bantu-speaking populations are analyzed, identifying 232 new sequences from basal haplogroups A and B and identifying new clades in the phylogeny.

An unbiased resource of novel SNP markers provides a new chronology for the human Y chromosome and reveals a deep phylogenetic structure in Africa.

TLDR
The experimental design produced an unbiased resource of new MSY markers informative for the initial formation of the anatomically modern human gene pool, i.e., a period of the authors' evolution that had been previously considered to be poorly accessible with paternally inherited markers.

A recent bottleneck of Y chromosome diversity coincides with a global change in culture.

TLDR
A study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples, infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky, and hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.

The evolutionary history of Neandertal and Denisovan Y chromosomes

TLDR
It is found that the Denisovan Y chromosomes split around 700 thousand years ago from a lineage shared by Neandertal and modern human Y chromosomes, which diverged from each other around 370 kya, providing strong evidence that gene flow from an early lineage related to modern humans resulted in the replacement of both the mitochondrial and Y chromosomal gene pools in lateNeandertals.

Sequencing Y Chromosomes Resolves Discrepancy in Time to Common Ancestor of Males Versus Females

TLDR
The findings suggest that, contrary to previous claims, male lineages do not coalesce significantly more recently than female lineages.

Y-Chromosome Variation in Southern African Khoe-San Populations Based on Whole-Genome Sequences

TLDR
High-coverage sequencing of the whole Y chromosome in a data set of 19 male Khoe-San individuals in comparison with existing whole Y-chromosome sequence data is described and the positioning of tentatively placed new branches of the ISOGG Y- Chromosome phylogeny is improved.

A calibrated human Y-chromosomal phylogeny based on resequencing.

TLDR
A nearly 10-fold increase in the number of Y markers with phylogenetic information, and novel historical insights derived from placing them on a calibrated phylogenetic tree are provided.

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.

A recent common ancestry for human Y chromosomes

TLDR
Inferences contradict predictions of the multiregional hypothesis positing a widespread transformation of Homo erectus populations into Homo sapiens and are consistent with auto-somal and mitochondrial DNA studies that suggest a long-term human effective population size of 10,000 and a sex ratio of 1.

Complete Khoisan and Bantu genomes from southern Africa

TLDR
The extent of whole-genome and exome diversity among the five men, reporting 1.3 million novel DNA differences genome-wide, including 13,146 novel amino acid variants, suggests the Bushmen seem to be more different from each other than, for example, a European and an Asian.

Out of Africa and back again: nested cladistic analysis of human Y chromosome variation.

TLDR
It is inferred that one of the oldest events in the nested cladistic analysis was a range expansion out of Africa which resulted in the complete replacement of Y chromosomes throughout the Old World, a finding consistent with many versions of the Out of Africa Replacement Model.

An early divergence of KhoeSan ancestors from those of other modern humans is supported by an ABC-based analysis of autosomal resequencing data.

TLDR
Substantial support is found for a model of an early divergence of KhoeSan ancestors from a proto-Pygmy-non- Pygmy NKs group ∼110 thousand years ago over a model incorporating a proto-' proto-KhoeSan-pygmy hunter-gatherer divergence from the ancestors of non- pygmyNKs.

Genetic evidence for a higher female migration rate in humans

TLDR
It is found that Y chromosome variants tend to be more localized geographically than those of mtDNA and the autosomes, and the reduction of variation within populations for Y chromosome single nucleotide polymorphisms (SNPs) is of such magnitude that differences in the effective population sizes of the sexes alone are insufficient to produce the observation.

Bayesian inference of ancient human demography from individual genome sequences

TLDR
This work used a Bayesian, coalescent-based approach to obtain information about ancestral population sizes, divergence times and migration rates from inferred genealogies at many neutrally evolving loci across the genome.
