The History and Geography of Human Genes
Hailed as a breakthrough in the understanding of human evolution, The History and Geography of Human Genes offers the first full-scale reconstruction of where human populations originated and the paths by which they spread throughout the world. By mapping the worldwide geographic distribution of genes for over 110 traits in over 1800 primarily aboriginal populations, the authors charted migrations and devised a clock by which to date evolutionary history. This monumental work is now available in a more affordable paperback edition without the myriad illustrations and maps, but containing the full text and partial appendices of the authors' pathbreaking endeavor.

It is a book of great value. Actually, it is easy to read, but it is not a popular work. In fact it is a complex and detailed research project, which provides a key point of reference for students and specialists of biology, anthropology, evolutionary psychology, history, paleontology, linguistics, archaeology, etc. I mean, all of those people who scientifically study the history and the development of homo sapiens. Because of its nature, though, this book has an analytical and schematic approach, which makes it a scientific and technical consultation text, not just a pleasant reading. It is a multidisciplinary manual, and it is based on a rigorous scientific methodology. If you like, it may also be seen as a brilliant manual of prehistory, often describing the consequences of the Paleolithic, Mesolithic and Neolithic humanity stages for the modern history.

The book examines the distribution of human genetic variability by linking it to prehistoric migrations, archaeological contexts, and language families. The authors used more than 100k gene frequency data, isoline mapping, principal component analysis, genetic distances, and phylogenetic trees. The sample includes populations considered native before 1492, to reduce the effect of recent historical diasporas.
The most important takeaway is that multilocus analysis reveals that about 84% of the genetic variance is found within each population, 8% between populations on the same continent, and 8% between different continents. This proportion shows that the average differences between individual humans are much higher than the average differences between large geographic groupings.
Since intercontinental variance is minimal compared to intrapopulation variance, traditional racial categories do not rest on any robust statistical or scientific basis.
Gene frequency maps show gradual transitions without clear taxonomic boundaries, apart from a few strong geographic barriers such as the Sahara and the Himalayas.
Mitochondrial and Y-chromosome indicators support an African root dating back more than 150,000 years. The progressive reduction in heterozygosity along the Northeast African route, the bottleneck outside Africa, and the progressive loss of rare variants confirm a pattern of successive wave expansions.
The suggested chronological order is: Africa -> Middle East -> Europe and Southeast Asia -> Oceania -> Americas.
Comparing genetic dendrograms and language rankings, the authors find that 31 out of 33 European genetic barriers coincide with primary language changes. The most striking correspondences are observed among Afro-Asiatic, Uralo-Altaic and Austronesian families, where particular demographic flows spread DNA and vocabulary together.
Divergences also exist, e.g., Hungarian and Lapp populations, who speak Uralic languages but are genetically similar to their Indo-European neighbors, signaling language substitutions without extensive demic replacement.
The F-ST coefficient increases on average by 0.001 per 1,000 km up to about 10,000 km, then flattens out. This correlation indicates a pattern of isolation by distance, attenuated by natural barriers and enhanced by bottlenecks.
Drift explains marked local differences such as the high frequency of negative Rh in Basques or HLA B*51 in Armenians. Local selection acts on specific loci: HbS in malarial areas, persistent lactase in pastoral societies, skin pigmentation correlated with latitude.
The effect of climate on the genetic core is modest, more pronounced for loci related to pigmentation and body morphology.
Africa: the most genetically heterogeneous continent. Mitochondrial lineages L0, L1, and L2 dominate in sub-Saharan Africa, while L3 is most common in the Horn of Africa and among African Americans.
Asia: drastic north/south dichotomy. The Himalayan corridor sharply divides northern clusters (high frequency of the edei marker) from southern clusters (peak HbE allele). Central Asian populations serve as a bridge between East and West.
Europe: the main gradient follows the Anatolia -> Ireland axis. Genetic isolates such as Sardinians, Lapps, and Basques show F-ST distances of up to 0.015 from their neighbors.
Americas: Asian founders entered via Bering between 15 and 12 thousand years ago, diversified into at least three waves (Na-Dene, Eskimo-Aleut, Amerindian). Low variability (intra-tribal F-ST ~0.05) but pronounced local shifts due to drift.
Implications for transplantation medicine: HLA variability follows clines precisely described by genetic research, so national registries must cooperate in contiguous regions.
Coincidences between language families and genetic clades suggest demographic and cultural co-diffusion. Linear regression between genetic diversity of large groupings and number of languages spoken (R² ≈ 0.9).
Implications for cultural history: strong gene-language correspondence provides a quantitative tool for testing hypotheses about displacement of pre-literate populations.
The integration of modern genomics and ancient DNA may refine chronology and trajectories, but it is unlikely to change the general figure outlined by the authors.

Un grande libro che descrive i risultati di decenni di lavoro relativi alla genetica delle popolazioni, materia di cui gli autori sono tra i principali esponenti mondiali. Libro oggi un po' datato perché nel frattempo sono intervenuti i dati sul DNA (mentre questo libro si basa sui componenti dell'analisi del sangue), mantiene però un incredibile fascino metodologico e mostra una capacità interpretativa veramente unica. Inoltre, a parte qualche interpretazione poi rivista successivamente sulla base dei risultati da DNA, le conclusioni esposte sono ancora validissime. Libro di confine tra divulgazione e testo scientifico, in alcune parti può risultare difficile al lettore inesperto nel trattamento di dati scientifici.

December 19, 20199.5/10. An amazingly detailed, encyclopedic primary resource on human biodiversity, heredity, ancestral descent, and recent (<100kya) evolution which is only minimally contaminated by the typical post-Montagu/Ehrenberg anthropological dogmata often coloring works of this type. Quite technical and not easily accessible to a layman with no understanding of genetics or math (but not technical like Penrose's 'Road to Reality', which isn't accessible even to an expert).

This book is originally more than 1000 pages, but made compact to the average readers in this abridged edition. I have to confess the particular statistical analysis that formed the basis of genetical studies in this book is way above my head, but the readable prose make it possible for me, as the amateur enthusiast to get the overreaching picture. This might be one of the most reliable primary sources in genetics available in the recent years.
The book covered a 100,000 years of human history, with detailed timeline inserted for each continents. A concise summary was that there are theories regarding modern human. The first was the polycentric model, which believed that ancient modern human directly "evolved" from indigenous homo erectus population occupying the area. There are 4 such areas recognized; European (the Neanderthals), Asia, Africa and Indonesian homo erectus. The one that the author tried to put forward is the more popular "out-of Africa" theory. Following this theory, it was stipulated that the ancient modern human was the direct descendants of the African homo erectus. These are evidenced by recent mitochondrial studies (a structure in the cell, transmitted only via matrilineal lin) that showed most of human populations in the world are derived from an "Eve" which lived in Africa around 100,000 years ago.
Before you jumped in happiness for the discovery of this "Eve", it must be emphasized that what it means is not that this is the one Eve, the biblical figures who is supposed to be the progenitor of human kind. What it means is just that this "Eve" has won the biological lottery of having her descendants the one who occupied modern world. What it also means is that, there are other contemporary "Eves" who lived with her but their descendants died over time.
And so, with the support of the mitochondrial studies, the author believed that ancient modern human spilled over from Africa, occupying the nearest node at the Middle East, around 100,000 years ago. From then, they occupied Asia and arrived at Australia around 50,000 years ago. Migration to Europe was believed to have its origin from Asia, around 32,000 years ago. The entry into America was via Beringia, a strip of land connecting the Old World to the New World around 10-15,000 years ago. These waves of ancient modern human was then believed to displace the archaic humans, such as the Neanderthals but either through peaceful coexistence or brutal displacement, the fact remains in the dark.
Linguistics followed closely with genetic spread, with exceptions only appear in the more recent times. Language is an instrument of communication derived solely from parents and immediate people; they are totally devoid of extraneous source for them to acquire a new language. And so, linguistics study goes in parallel with genetic study as a support tracking ancient migration.
Another important question that the author tried to answer was that: did the migrations expand physically or through cultural diffusion? The author proposed the former, called as demic expansion, where the Neolithics farmer migrate ever forward from the epicenter of complex agriculture in the Fertile Crescent. He argued that modern hunter-gatherers such as the African Pygmies, persists in their way of live despite living next to communities of farmers. He also included, of course, more complex arguments supporting demic expansion in this volume.
Moving on to questions that directly relevant to my curiosity: the origin of the Malays. Specific sub-chapters on Southeast Asia reveals that the waves of ancient human migration passed through the mainland and insular Southeast Asia around 50,000. Some of these communities progressed further into Australia and Melanesia. It is of important note that Southeast Asia was still a united block of land prior to rise of sea-levels, forming the locally popular Sundaland. The one left in the Sundaland then propagated to the modern Indochina, Taiwan, Philippines, Borneo and Indonesia and Peninsular Malaysia. Relevant to the Malayan Archipelago, this first settlers could be the oft-mentioned Proto-Malays. Further genetical studies revealed further waves of migration from Taiwan; the displacement of aboriginal Taiwanese by the encroaching Sino-Tibetan speakers from mainland China. These are the Austronesian people, who might be the Deutro-Malays, according to the popular theory.
New things I have learnt is the inclusion of modern Indochina and even Southern Chinese as our genetic brethren. The author even included their language into the larger linguistic families of Austric-Tai. But from the genetic tree, it is clear that the Tai and Austroasiatic speakers branched off earlier from Peninsular and Insular population. With the incursions of the Austronesian people, what's left of these Tai and Austroasiatic speakers might became isolated and retreated to the mountains, in the form of the Semang whose language showed relics of Mon-Khmer language, one of the Tai language offshoots. So the alternative theories of Yunnan and South Indian origin of the Malays are sufficiently disproved. Ironically, it was the advance of Sino-Tibetan mainland people into the Taiwan that sparked the Austronesian migration. The existence of the Munda exclaves, an Austronesian speaker now living in the Orissa region of India, showed the net direction of migration, if any, was from the Archipelago into India, instead of the other way around.
Another important thought sufficiently refuted was the claim that the Malays are originated from the Arabs, specifically the 3rd (or is it the 4th now?) wife of Abraham, the mysterious figure known as Katurah. Genetic studies showed that Arabic influence among the Malays, as a population, is negligible, aside from the isolated pockets of intermarriages that happened much later during the Archipelago's zenith as an entrepot.

Absolutely stunning. The result of over 30 years' work by hundreds of scientists. A must for any historian, anthropologist, linguist or paleontologist. Should be of great interest to any scientist.
The authors have applied sophisticated statistical analysis to the evidence from samples of blood taken from thousands of people around the world. It is amazing how much information is teased out. Huge amounts of computing time were required.
They look at dozens of alleles (minor mutations) which can be traced in populations over space and time. The primary mathematical method is identification of principal components by multivariate analysis. Most interesting is the resulting geographical mappings of gene flow. There are very many of great interest. For example, they show the three major migrations into North America from Beringia. They confirm that the dispersion of farming out of Anatolia 8,000 years ago was from migrations of farmers rather than merely the spread of a farming culture.
The authors freely draw from the fields of anthropoly, paleontology and linguistics (and occasionally written history) to supplement and complement the genetic data.
(The work shows clearly that race is not of genetic significance, never mind what you may possibly read elsewhere due to misunderstanding.)
