Haplogroup L (Y-DNA) : ウィキペディア英語版 | Haplogroup L-M20
In molecular evolution, a haplogroup (from the (ギリシア語:ἁπλούς), ''haploûs'', "onefold, single, simple") is a group of similar haplotypes that share a common ancestor having the same single nucleotide polymorphism (SNP) mutation in all haplotypes. Haplogroup L-M20 is a Y-chromosome DNA haplogroup, found in South Asia, Western Asia and Europe and is defined by SNPs M11, M20, M61 and M185. == Origins == Haplogroup L-M20 is associated with South Asia. It has also been found at low frequencies among populations of Central Asia, Southwest Asia, and Southern Europe along the coast of the Mediterranean Sea. It is a descendant haplogroup of haplogroup K-M9, and is believed to have first appeared approximately 30,000 years ago. Gareth Henson, administrator of the Haplogroup T project at FTDNA, has theorized "I think both T and L originated in the Iraq/Iran region...the branches of L all went in different directions (L1 southeast, L2 west and L3 northeast)."
