Key Concepts

Remembering high school biology, women have two x chromosomes, one inherited from the father and one from the mother. Men have an x chromosome inherited from the mother and a y chromosome inherited from the father. This difference comes about because each sperm contains either an x chromosome or a y chromosome, while each egg always contains an x chromosome. An xy combination makes a person male...

Hauri DNA Project

All modern humans descend in the male line from a particular man, nicknamed Genetic Adam, who lived in Africa about 142 thousand years ago (~7,100 generations). All living men have inherited his y chromosome (yDNA), along with the mutations that have accumulated in our individual family lines. Unlike autosomal DNA, yDNA does not recombine. It passes intact from a man to his sons. (Women do not...

Haplogroup J

This haplogroup is found at highest frequencies in Middle Eastern and north African populations, where it probably evolved. This marker has been carried by Middle Eastern traders into Europe, central Asia, India and Pakistan. Brian Sykes used the name Re to represent the founder of Haplogroup J (Saxons, Vikings, and Celts, 2006). Haplogroup J1 This haplogroup originated in the Arabian peninsula...

Historic DNA

All living men have inherited their y chromosome from Genetic Adam, along with the mutations that have accumulated in their individual family lines. Geneticists can test for these accumulated mutations. By analyzing the mutations present in modern men, geneticists can group them. Individual test results show a man’s haplotype. Men with the same haplotype are likely to belong...

Haplogroups

All modern humans descend in the male line from a particular man, nicknamed “Genetic Adam,” who lived about 60,000 years ago. All living men have inherited his y chromosome (yDNA), along with the mutations that have accumulated in our individual family lines. Geneticists can test for these accumulated mutations. Individual test results show a man’s haplotype. Groups of similar haplotypes form...

Haplogroup G

Test results so far show that the majority of Hauris and Haurys from Switzerland and southern Germany belong to Haplogroup G2a. Haplogroup G is defined by a mutation at M201. The first man to have the M201 mutation is thought to have lived about 30 thousand years ago (~1,200 generations), probably south of the Caucasus mountains and perhaps near Lake Van, but perhaps along the eastern edge...

Human Origins

All modern humans descend in the male line from a particular man, nicknamed Genetic Adam, who lived in Africa about 142 thousand years ago (~7,100 generations). This is much older than previously thought. Geneticists discovered this information by mapping mutations on the y chromosomes of modern men. Before Adam Archaeological evidence shows modern humans emerged some 200 thousand years ago...

Haplogroup E

The founder of this lineage lived in east Africa, about 50 to 55 thousand years ago. Brian Sykes used the name Eshu to represent the founder of Haplogroup E (Saxons, Vikings, and Celts, 2006). Eshu is one of the gods of the Yoruba, a west African tribe. Haplogroup E1b1a This subgroup is an African lineage. The current theory is that this haplogroup dispersed south from northern Africa within...

What’s Next in the World of DNA Testing?

by Megan Smolenyak, Family Chronicle (January-February 2003) Over the last couple of years, genealogists have started to dabble in the world of genetic genealogy, or as I like to call it, “genetealogy.” When it finally became available on the individual consumer level, a few curious souls ventured forth to be the first in line to experiment on their own families with this new technology. As they...

Genealogists Turn to DNA in Tracing Family Trees

by Margie Wylie, Newhouse News Service (Jan. 28, 2001). Syndicated in The Wall Street Journal (June 15, 2001) and The Denver Post (June 16, 2001). About 15 months ago, Bennett Greenspan ran into an obstacle all genealogists eventually face: A dead end. Certain that he’d found an Argentine branch of his family, but unable to uncover the documents that would connect the two clans, Greenspan turned...
