Does anyone more versed in Iberian archeology than myself know if some of those brand-new Iberian samples inside Lipson et al. preprint actually qualify as Bell Beakers? If so, This specific would likely mean that will, unlike all Central European Bell Beakers sequenced to date, at least some of the earliest Spanish Bell Beakers lacked admixture coming from the Eurasian Steppe. This specific would likely also suggest that will, again, unlike Central European Bell Beakers, which show a high incidence of R1b, early Spanish Bell Beakers were rich in I2a2a. coming from the Lipson et al. supp info, pages 36-37, emphasis is actually mine:
Dolmen “El Sotillo” (Álava) El Sotillo megalithic site is actually located inside Alava Rioja county (Basque country), between the limit of Laguardia-Guardia along with Leza municipalities, at the south of the historical territory of Alava. The site is actually 617 meters above the sea level. This specific was discovered in 1955 by Domingo Fernández Medrano along with excavated by himself, José Miguel Barandiran along with Juan M. Apellániz in 1963 . This specific is actually a megalithic tomb which has a corridor along with an almost circular chamber, formed by nine slab stones, a corridor along which has a tumulus of eleven meters of diameter. During the excavation, numerous lithic tools were uncovered, including six pedunculated arrowheads of silex, a bone along which has a metal arrowheads, a metal burin, retouched flakes, two fragments of foliaceous projectile points, etc. There are some Bell Beaker pottery remains along which has a cup with incised decorations. The remains of thirteen individuals, including eleven adults (six of them males) were retrieved. The radiocarbon dates placed the initial use of the site at the Late Chalcolithic period, the Bell Beaker period (4390+30, 4350+30, 4040+30, 4000+40 BP). After a hiatus of about half a millennium, the usage of the structure as funerary place increased during the Middle Bronze Age period (3550+30, 3430+30, 3380+30, 3360+30, 3360+30, 3320+30, 3160+30, 3120+30 BP), with one date coming from the Late Bronze Age (2740+30 BP). La Chabola De La Hechicera (Álava) The dolmen of La Chabola de la Hechicera  is actually located inside Alava Rioja county, inside municipality of Elvillar. This specific is actually a corridor megalithic burial composed by a circular chamber formed by eight slab stones, along which has a corridor delimited by six slabs along with covered by a large slab stone. This specific was erected during the Late Neolithic along with was used in different periods, until the Bronze Age. This specific was discovered in 1935 by Álvaro de Gortazar along with has been excavated in several campaigns by different researchers (1936 José Miguel Barandiaran, 1947 Carlos Sáenz de Tejada, Álvaro Gortazar y Domingo Fernández Medrano, 1974 Juan María Apellániz along with 2010-2011 José Antonio Mujika y Javier Fernández Eraso). During these works, the remains of at least 39 individuals have been retrieved. Sylex arrowheads, personal ornaments (such as necklace beads along with pendants made coming from different materials), an idol made of bone along with pottery remains (including a well-preserved Bell Beaker cup inside Ciempozuelos style) were also retrieved. Twelve different radiocarbon dates were generated, yielding dates coming from the Late Neolithic to the Bronze Age: 3170+130; 3280+40; 4380+40; 4420+30; 4430+40; 4440+40; 4480+40; 4650+40; 4670+40; 4940+30; 4980+30 BP.
