Neolithic migration into Europe from Southwest Asia, by first wave of farmers in Europe has been put forward as the source of F and G2a found in European Neolithic remains, dating from circa 4000 BCE. These remains, according to Herrerra et al. (2012) showed a "greater genetic similarity" to "individuals from the modern Near East" than to modern Europeans. F(xG,H,I,J,K) "may" have been found in Bronze Age remains from Europe, namely the individuals known as "DEB 20" and "DEB 38", who lived about 7,000–7,210 BP, and were found at the Derenburg Meerenstieg II site in Germany.
