Genetics
It has been suggested that the Funnelbeaker culture was the origin of the gene allowing adults of Northern European descent to digest lactose. It was claimed that in the area formerly inhabited by this culture, prevalence of the gene is virtually universal. A paper published in 2007 by Burger et al. indicated that the genetic variant that causes lactase persistence in most Europeans (-13,910*T) was rare or absent in early farmers from central Europe. A study published by Yuval Itan and colleagues in 2010 clearly shows this. A study published in 2009, also by Itan et al., suggests that the Linear Pottery culture (also known as Linearbandkeramik or LBK), which preceded the TRB culture by some 1,500 years, was the culture in which this trait started to co-evolve with the culture of dairying.
Ancient DNA extracted from three individuals ascribed to a TRB horizon in Gökhem, Sweden, were found to possess mtDNA haplogroups H, J, and T.
