Subject: [DNA] Sykes' data shows E3b absent entirely from "Central England"
Date: Mon, 20 Nov 2006 13:23:25 -0500

I've been examining and plotting E3b haplotypes from Dr. Sykes' data,
corresponding to the OGAP. He classifies a region as "Central England,"
which appears to correspond roughly to the ancient Anglo-Saxon kingdom of
Mercia. (Offa was the most famous king of this kingdom; the one who
constructed Offa's Dyke.) The southern portion of "North England" on Sykes'
map appears to overlap with the northernmost portion of the Mercian kingdom,
but most of "Central England" appears to lie within the boundaries of what
once was Mercia.

What is interesting is the complete absence of E3b in this region, according
to the Sykes survey data of 193 haplotypes in Central England. The region
is surrounded by "North England," "East Anglia," "London," "South England,"
and "Wales" (the data set does not distinguish between South Wales,
Mid-Wales and North Wales). Within these regions, E3b appears at a
frequency of 2-5%. Capelli showed similar percentages in specific locations
surrounding this area, from 3-6% of the population, although he managed to
overlook the Sykes "Central England" area entirely.

There is a very low incidence of E3b in Ireland (0.44%), and 0% found north
and west of the "Loch Lomand" glacial line between Argyll and Hebrides, and
Grampian and the Highlands. Sykes found 3 samples out of 202 in the
Northern Islands, and Capelli found 0% in the Orkneys.

What is the explanation for this donut hole in the E3b distribution of
modern England? It can't be due to Neolithic settlement patterns, or the
Norman settlement pattern (which was all over this part of England). It
could very likely be due to displacement of local population by Mercian
invaders (in the 6th century). The difference between the absence of E3b in
Central England and the higher than average presence in the regions
surrounding Central England suggest such a displacement.

In fact, the ONLY event that would seem to me to account for the
displacement of E3b from this particular region of England would seem to be
the Anglo-Saxon invasion. Are there other historical events in Central
England which could explain such a pattern?
