Further mutations occurred in the J line, which can be identified as the subclades J1a1, J1c1 (27,000 yrs ago), J2a (19,000 yrs ago), J2b2 (16,000 years ago), and J2b3 (5,800 yrs ago). Haplogroup J bearers along with persons carrying the T mtDNA clade settled in Europe from the Near East during the late Paleolithic and Mesolithic.

With a 95% probability, the most recent common ancestor of all members of haplogroup J2a1a was born between the years 9234 and 6841 BCE. The most likely estimate is 8002 BCE , rounded to 8000 BCE . This estimate will likely change in the future as …

除了青铜时代末匈牙利的1个J2a1b样品（约公元前1150年，见冈巴等人，2014年）外，J2在所有红铜和青铜时代的印欧文化中均未被发现。 这个J2a1b样本来自骨灰瓮文化的一个分支—— Kyjatice文化。 这种文化使用火葬而不是单墓葬，与典型的印欧文化非常不同。 （译者注：火葬可能是造成J2样本量较少的原因） 迄今为止，中亚和南亚的新石器时代样本还没有测出过J2，但通过目前的地理分布来看，J2可能在新石器时代，从 扎格罗斯山脉 和 美索不达米亚 北部开始扩 …

What is Maternal Haplogroup J2a1a? Haplogroup J2a1a is a genealogical group of lineages defined by unique genetic markers present in your mitochondrial DNA, which is transmitted from your mother. Your maternal haplogroup paints a picture of your ancient origins and the migrations of your ancestors.

Subgroup J2a1a originated about 11,000 years ago perhaps in Spain. It spread into Europe after the last Ice Age. Haplogroup J (along with ‘T’) is associated with the spread of farming and herding in Europe during the Neolithic Era (8,000-10,000 yrs ago).

Every new mtFull Sequence test result helps improve the tree structure and age estimates. A popular genealogy strategy is to expand your part of the tree by encouraging distant relatives to test.

2017年3月9日 · J is an mtDNA Haplogroup. This phylogenetic tree of haplogroup J subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [PMID 18853457] and subsequent published research.

The DNA of two male Minoan indivuals was tested in 2020 and they belonged to G2a-P303 and J2a1a-L26 > Z6055 > Y7010 > Y13128 > Z36834 (a branch found in Portugal today). The Phoenicians, Jews, Greeks and Romans all contributed to the presence of J2a in Iberia. The particularly strong frequency of J2a and other Near Eastern haplogroups (J1 ...

Haplogroup J, a mitochondrial DNA lineage, originated approximately 45,000 years ago in West Asia, splitting into subclades J1 and J2 over the following millennia.

The third is an unresolved reticulation at J2a1a. It appears that G513A and A3447G could be used to define a new branch, but so could T1850C, together with the T insertion at position 310. However these two potential definitions have a substantial overlap making clear definition impossible. This situation also occurs at
