There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
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] The final phase of the project was Geno 2.0 Next Generation. [2]
Furthermore, although human populations show some genetic clustering across geographic space, human genetic variation is "clinal", or continuous. [12] [10] This, in addition to the fact that different traits vary on different clines, makes it impossible to draw discrete genetic boundaries around human groups. Finally, insights from ancient DNA ...
The National Geographic Society's Genographic Project aims to map historical human migration patterns by collecting and analyzing DNA samples from over 100,000 people across five continents. The DNA Clans Genetic Ancestry Analysis measures a person's precise genetic connections to indigenous ethnic groups from around the world.
The human genome has approximately 3.1 billion base pairs. [69] The Human Genome Project was started in 1990 with the goal of sequencing and identifying all base pairs in the human genetic instruction set, finding the genetic roots of disease and then developing treatments. It is considered a megaproject.
The Human Genome Diversity Project (HGDP) was started by Stanford University's Morrison Institute in 1990s along with collaboration of scientists around the world. [1] It is the result of many years of work by Luigi Cavalli-Sforza, one of the most cited scientists in the world, who has published extensively in the use of genetics to understand human migration and evolution.

A wide range of methods have been developed to assess the structure of human populations with the use of genetic data. Early studies of within and between-group genetic variation used physical phenotypes and blood groups, with modern genetic studies using genetic markers such as Alu sequences, short tandem repeat polymorphisms, and single nucleotide polymorphisms (SNPs), among others.
