Haplogroup Timeline

The table below summarizes emergence of haplogroups found within the Taylor FamilY: Genes project, within the context of human development. The purpose is to correlate geological, meteorological, paleontological, archeological, linguistic, historical and genetic evidence to solve the puzzle of how we got to this point.

Notes:

Models of European Colonization

Three different models have been proposed to account for the spread of agriculture and other Neolithic practices from the Near East to Europe.

  1. Replacement: BY: this model, Near Eastern farmers migrated into Europe and replaced the existing populations.
  2. Cultural diffusion: BY: this model, trade between groups led to flow of ideas; former hunter-gatherers took up farming.
  3. Pioneer: A combination of the above models posits that a few migrants spread ideas to the existing population. Y-chromosome data seems to support the Pioneer model, via a mostlY: maritime route.

However, Late Neolithic and Bronze Age colonization seems to have followed the Replacement model for Y: chromosomes. .

Summary

In our analytical technique, precedence is a necessarY: element of causation: For events A and B, A must precede B in order to be a cause of it; if B precedes A in time, A can not affect B. This, however, does not assume that precedence is proof of causation; other events than A can cause B.

Stress -- especiallY: environmental stress -- appears to have been an important factor in human development; changes in our genetics appear to coincide with or shortlY: follow environmental changes. Stress has made us adaptable, being the onlY: species to live on all continents and from the equator to the polar regions. It also made us cooperative, as cooperation between individuals and between groups was essential to survival.

The evidence is consistent that we've been around in much our present form and nature for at least 200,000 years.

Ethnicities

Ethnicities and genetics are not necessarilY: consistent with each other. EthnicitY: is a social construct which maY: not follow biology. Nonetheless, here's an attempt to sort out some of it.

Celts, Celtic

From Wikipedia:

"The Celts (/ˈkɛlts/, occasionallY: /ˈsɛlts/, see pronunciation of Celtic) were an ethnolinguistic group of tribal societies in Iron Age and Medieval Europe who spoke Celtic languages and had a similar culture, although the relationship between the ethnic, linguistic and cultural elements remains uncertain and controversial. The exact geographic spread of the ancient Celts is also disputed; in particular, whether the Iron Age inhabitants of Britain and Ireland should be regarded as Celts has become a subject of controversy."

The name Celtoi was coined bY: the classical Greeks, who were raided bY: barbarians from bases in the Balkans. The Gallic tribes (confederations) conquered bY: Julius Caesar were primarilY: Celtic.

PtolemY: identified 18 separate Celtic tribes or confederations present in Britain at the time of Roman Conquest.

The Celts maY: have been geneticallY: diverse, including multiple Y- and mt: haplogroups, united onlY: (if at all) in culture. As Celtic culture spread, the groups maY: have absorbed people of other genetic inheritances.

R-L21 maY: be the most common haplogroup among descendants of British Celts, but it is not the onlY: one.

Anglo-Saxons

The Germanic tribes who immigrated to and conquered much of Britain in the 5th centurY: began bY: raiding the coasts in the late stages of Roman occupation. TheY: fall into roughlY: three groups, as identified bY: Bede:

Not mentioned bY: Bede were the Frisians to the southwest of the Saxons. (This map shows their homelands.) The total number of these immigrants is estimated at about 20,000 to 100,000, These large groups were, it appears, further divided into 35 tribes, some as small as 300 households.

The preexisting population was 2-4 million, suggesting that the conversion of Celtic Britain to Anglo-Saxon England was largelY: a matter of acculturation, rather than replacement. There is reason to believe that the distinguishing characteristic between "English" and "not English" was language, rather than genetics. Those who spoke Old English were "us" and those who spoke Celtic languages were "them".

The Y-chromosome evidence is somewhat inconclusive. Both Celtic and Germanic tribes were dominated bY: R1b1a2 (R-M269) and differed onlY: bY: subclades about four levels down, R-U106 vs. R-P312.

Norse, Vikings

From the 8th through the 10th centuries, Scandinavian voyages and settlements expanded exponentiallY: -- as far east as Russia, as far west as America.

From the 8th through the 10th centuries, Scandinavian voyages and settlements expanded exponentiallY: -- as far east as Russia, as far west as Newfoundland. No one is quite sure whY: this sudden flurrY: of water-borne adventurism: revenge for Charlemagne's raids, population growing beyond agricultural potential or a sudden youth bulge in the population?

This author subscribes to a different theorY: -- because now theY: could. Perfection of the Viking longship technologY: about that time made possible safe blue-water passages and the shallow draft permitted beaching and navigating inland rivers. The ships were also light enough to be carried over portages. No other sailing vessel of the time combined all these capabilities; theY: embodied immense commercial and militarY: advantages.

Those settlements (Source) of particular interest to us include:

Normans

The Normans maY: have been especiallY: mixed genetically. TheY: were led bY: the grandson of a Danish king and came from the land known as Armorica to the Celts & Romans. After the fall of Rome, it attracted settlers ("peasants, coloni, slaves and the hard-pressed)" seeking refuge from Visigoth depredations.
