[citation needed] Notably, the haplogroup is especially common, at 14.3%, among the natives of Bahariya Oasis (Western Desert, Egypt.

Subclade X2 appears to have undergone extensive population expansion and dispersal around or soon after the Last Glacial Maximum, roughly 20,000 years ago.

Haplogroup X has been found in various other bone specimens that were analysed for ancient DNA, including specimens associated with the Alföld Linear Pottery (X2b-T226C, Garadna-Elkerülő út site 2, 1/1 or 100%), Linearbandkeramik (X2d1, Halberstadt-Sonntagsfeld, 1/22 or ~5%), and Iberia Chalcolithic (X2b, La Chabola de la Hechicera, 1/3 or 33%; X2b, El Sotillo, 1/3 or 33%; X2b, El Mirador Cave, 1/12 or ~8%) cultures.

[9] Abel-beth-maachah 2201 was a man who lived between 1014 and 836 BC during the Levant Iron Age and was found in the region now known as Abel Beth Maacah, Metula, Israel.

[10] Fossils excavated at the Late Neolithic site of Kelif el Boroud in Morocco, which have been dated to around 5,000 years old, have also been found to carry the X2 subclade.

[11] In Eurasia, the greatest frequency and variety of haplogroup X is observed in the Druze, a minority population in Israel, Jordan, Lebanon, and Syria, as much in X1 (16%) as in X2 (11%).

The Galilee Druze represent a population isolate, so their combination of a high frequency and diversity of X signifies a phylogenetic refugium, providing a sample snapshot of the genetic landscape of the Near East prior to the modern age.

[12] This relative absence of haplogroup X2 in Asia was one of the major factors used to support the Solutrean hypothesis during the early 2000s.

The Solutrean hypothesis postulates that haplogroup X reached North America with a wave of European migration emerging from the Solutrean culture, a stone-age culture in south-western France and in Spain, by boat around the southern edge of the Arctic ice pack roughly 20,000 years ago.
