Many folk are well aware of how 37 or 67 Y-DNA marker tests can be used to identify matches within a genealogical time frame, but there is an increasing and welcome interest in 'deep ancestry'.
The history of the human Y-DNA tree is defined at each branch by an SNP (a single-nucleotide polymorphism), a change to a single nucleotide in a DNA sequence. These events are rare but when they do happen, every descendant of the individual in which the event occurred will carry the mutation to the next generation.
Steve St Clair has posted a very helpful video of recent developments in his project which can be viewed here St. Clair DNA Study
I would also recommend a visit to the St. Clair DNA Study website where there are interviews with Bennett Greenspan, Terry Barton and Richard White
