The authors of this study look at the depth of L3F in Austrias, Spain, which is at the opposite end of Iberia from where L3F was found in respectable numbers in Chalcolithic SE Iberia. (Fernandez et al, 2006) and (Gamba et al., 2008)
At one time this was linked to either the proverbial black gladiator or a non-existent Paleolithic wanderer. But its age and frequency seem to tell another story.
Maternal Haplogroup L3F has been previously linked to Chadic speaking pastoral migrations (Cerny et al, 2009) R1b-V88 also has been linked with Chadic expansion. (Cruciani et al, 2010)
As with L3F, it appears that V88's depth in Europe does not lend itself to a wandering Medieval vagabond. [Maglio, 2014]
It's noteworthy that many of the modern Sahelian pastoral populations have the additional tandem presence of H1 + H3 along with V, which could be considered proto-Beaker (Brotherton). This is true in Algeria as well as parts of the Southern Sahel.
The incandescent light bulb slowly flickered when thinking about "bificial thinning using surface pressure flaking" on a barbed and tanged arrowhead and its emergence in Iberia before the maturation or emergence of proper Bell Beaker.
In essence, although R1b-V88 and L3F are very low frequency in Europe and form a sort of cline from the Southwest, I think they may be like our marked honeybee for something that was much larger.
