Overview map of the peopling of the world by early humans during the Upper Paleolithic, following the Southern Dispersal paradigm. The so-called "recent dispersal" of modern humans took place about 70–50,000 years ago. [60] [61] [62] It is this migration wave that led to the lasting spread of modern humans throughout the world.
The Genographic Project, launched on 13 April 2005 by the National Geographic Society and IBM, was a genetic anthropological study (sales discontinued on 31 May 2019) that aimed to map historical human migrations patterns by collecting and analyzing DNA samples. [1]
World map of human migrations, with the North Pole at center. Made in 2005. Africa, harboring the start of the migration, is at the top left and South America at the far right. Migration patterns are based on studies of mitochondrial (matrilinear) DNA. Dashed lines are hypothetical migrations. Numbers represent thousand years before present.
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
Haplogroup X is a human mitochondrial DNA (mtDNA) haplogroup. It is found in North America, Europe, Western Asia, North Africa, and the Horn of Africa. A mtDNA-based map of major human migrations. Haplogroup X diverged from haplogroup N roughly 30,000 years ago (just prior to or during the Last Glacial Maximum).
Hypothesized map of human migration based on mitochondrial DNA. A number of studies have proposed that the ancestors of modern haplogroup M dispersed from Africa through the southern route across the Horn of Africa along the coastal regions of Asia onwards to New Guinea and Australia.
The findings come from a huge project to compare modern DNA with that culled from ancient humans’ teeth and bones — allowing scientists to trace both prehistoric migration and disease-linked ...
Map of human haplotype migration, according to mitochondrial DNA, with key (coloured) indicating periods in numbered thousands of years before the present. Haplogroups can be used to define genetic populations and are often geographically oriented. For example, the following are common divisions for mtDNA haplogroups:
