TLDR
This pattern indicates that the first settlement of modern humans in eastern Asia occurred in mainland Southeast Asia during the last Ice Age, coinciding with the absence of human fossils in easternAsia, 50,000-100,000 years ago.Abstract:
Summary The timing and nature of the arrival and the subsequent expansion of modern humans into eastern Asia remains controversial. Using Y-chromosome biallelic markers, we investigated the ancient human-migration patterns in eastern Asia. Our data indicate that southern populations in eastern Asia are much more polymorphic than northern populations, which have only a subset of the southern haplotypes. This pattern indicates that the first settlement of modern humans in eastern Asia occurred in mainland Southeast Asia during the last Ice Age, coinciding with the absence of human fossils in eastern Asia, 50,000–100,000 years ago. After the initial peopling, a great northward migration extended into northern China and Siberia.read more

TL;DR: The availability of the near-complete chromosome sequence, plus many new polymorphisms, a highly resolved phylogeny and insights into its mutation processes, now provide new avenues for investigating human evolution.

TL;DR: Major changes in the topology of the parsimony tree are described and names for new and rearranged lineages within the tree following the rules presented by the Y Chromosome Consortium in 2002 are provided.

A nomenclature system for the tree of human Y-chromosomal binary haplogroups
TL;DR: A simple set of rules was developed to unambiguously label the different clades nested within a single most parsimonious phylogeny, which supersedes and unifies past nomenclatures and allows the inclusion of additional mutations and haplogroups yet to be discovered.

TL;DR: A set of unique event polymorphisms associated with the non‐recombining portion of the Y‐chromosome (NRY) addresses this issue by providing evidence concerning successful migrations originating from Africa, which can be interpreted as subsequent colonizations, differentiations and migrations overlaid upon previous population ranges.

Large-Scale Psychological Differences Within China Explained by Rice Versus Wheat Agriculture
TL;DR: This study tested 1162 Han Chinese participants in six sites and found that rice-growing southern China is more interdependent and holistic-thinking than the wheat-growing north, and it is found that modernization and pathogen prevalence theories do not fit the data.

TL;DR: All these mitochondrial DMAs stem from one woman who is postulated to have lived about 200,000 years ago, probably in Africa, implying that each area was colonised repeatedly.

TL;DR: The African origin hypothesis of human mtDNA evolution is supported by two statistical tests and two hypervariable segments of mtDNA were sequenced from 189 people of diverse geographic origin, including 121 native Africans.

TL;DR: It is suggested that Y-STR loci are useful markers to identify males and male lineages in forensic practice and recommended for the forensic application of a basic set of 7 STRs for standard Y-haplotyping in forensic and paternity casework.
