One final thing: this is the map of continental DNA they compared GB DNA to....notice any gaps?! *Anglo*-Saxons ;)pic.twitter.com/NBwTiMlaZ5

@caitlinrgreen@DrDonnaYates thanks for perspective. Before I share that article w/ Ts & Ss, can you suggest links to other articles?> -
@Wozleigh@DrDonnaYates Härke's papers are easily available online, eg. https://www.academia.edu/1178275/Anglo-Saxon_immigration_and_ethnogenesis._Medieval_Archaeology_55_2011._1-28 … & https://www.academia.edu/468159/Evidence_for_an_apartheid-like_social_structure_in_early_Anglo-Saxon_England._Proceedings_of_the_Royal_Society_B_273_July_2006_2651-2657 …. Tbh, the new > -

@Wozleigh@DrDonnaYates > Anglo-Saxons grew over pre-Viking era to reach modern levels as result of social/political structures :) -
@Wozleigh@DrDonnaYates (i.e. that immigrant 'Germanic' DNA grew from 5-10% to c.20% of total in S/CentEng, just to be clear on what mean!)

@caitlinrgreen always tough to find good resources for them. -
@Wozleigh Not sure those articles will work for those age groups, tbh, but 1st one might help for extension work!? -
@caitlinrgreen well, they are the advanced students
. Would you ever consider skyping with us? (Not abt genetics)
