It should not be forgotten the following: 

 A study (published 2007) using 6,501 unrelated Y-chromosome samples from 81 populations found that: “Considering both these E-M78 sub-haplogroups (E-V12, E-V22, E-V65) and the E-M81 haplogroup, the contribution of northern African lineages to the entire male gene pool of Iberia is 5.6%. ”[50] 

 In terms of the number of samples much bigger, even 10 times bigger, than the others. Anyway, again, summary needed. Jan.
