Before Common Era
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year. The expression traces back to 1615, when it first appeared in a book by Johannes Kepler as the la, annus aerae nostrae vulgaris (), and to 1635 in English as " Vulgar Era". The term "Common Era" can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish religious scholars. Since the later 20th century, BCE and CE have become popular in academic and scientific publications because BCE and CE are religiously neutral terms. They are used by others who wish to be sensiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup IJK (Y-DNA)
Haplogroup IJK is a human Y-chromosome DNA haplogroup. IJK is a primary branch of the macrohaplogroup HIJK. Its direct descendants are haplogroup IJ and haplogroup K. Distribution and structure The basal paragroup HIJK* has been found in a Mesolithic European ( Magdalenian), GoyetQ-2, and the basal IJK was found in an Upper Paleolithic European (Gravettian), Vestonice16. Populations with high proportions of males who belong to descendant major haplogroups of Haplogroup HIJK live across widely dispersed areas and populations. Subclades of IJK are now concentrated in males native to: *Europe (e. g. haplogroups I, J, R and N); *the Caucasus, Near East and North East Africa (e.g. haplogroups J and T); *South Asia (e.g. haplogroups J, L and R); *East Asia，Southeast Asia, Oceania, and the Pacific (e. g. haplogroups K, M, O, P, S) *Northern Eurasia, (e.g. haplogroups N and Q) and; * Native American peoples (e. g. haplogroup Q and R).

Modern Era
The term modern period or modern era (sometimes also called modern history or modern times) is the period of history that succeeds the Middle Ages (which ended approximately 1500 AD). This terminology is a historical periodization that is applied primarily to European and Western history. The modern era can be further divided as follows: * The early modern period lasted from c. AD 1500 to 1800 and resulted in wide-ranging intellectual, political and economic change. It brought with it the Age of Enlightenment, the Industrial Revolution and an Age of Revolutions, beginning with those in America and France and later spreading in other countries, partly as a result of upheavals of the Napoleonic Wars. * The late modern period began around 1800 with the end of the political revolutions in the late 18th century and involved the transition from a world dominated by imperial and colonial powers into one of nations and nationhood following the two great world wars, World War I and W ...

Haplogroup T (Y-DNA)
Haplogroup T-M184, also known as Haplogroup T, is a human Y-chromosome DNA haplogroup. The unique-event polymorphism that defines this clade is the single-nucleotide polymorphism known as ''M184''. Other SNPs – ''M272'', ''PAGES129'', ''L810'', ''L455'', ''L452'', and ''L445'' – are considered to be phylogenetically equivalent to ''M184''. As a primary branch of haplogroup LT (a.k.a. K1), the basal, undivergent haplogroup T* currently has the alternate phylogenetic name of K1b and is a sibling of haplogroup L* (a.k.a. K1a). (Before 2008, haplogroup T and its subclades were known as haplogroup K2. The name K2 has since been reassigned to a primary subclade of haplogroup K.) It has two primary branches: T1 (T-L206) and T2 (T-PH110). T-M184 is unusual in that it is both geographically widespread and relatively rare. T1 (T-L206) – the numerically dominant primary branch of T-M184 – appears to have originated in Western Asia, and possibly spread from there into the East A ...

Haplogroup R (Y-DNA)
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa. Some authorities have also suggested, more controversially, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted. According to geneticist Spencer Wells, haplogroup K, from which haplogroups P and Q descend, originated in the Middle East or Central Asia. "Given the widespread distribution of K, it probably arose somewhere in the Middle East or Central Asia, perhaps in the region of Iran or Pakistan." However, Karafet et al. (2014) proposed that "rapid diversification ... of K-M526", also known as K2, likely occurred in Southeast Asia (near Indonesia) and later expanded to mainland Asia, although they could ...

Haplogroup Q (Y-DNA)
Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has one primary subclade, Haplogroup Q1 (L232/S432), which includes numerous subclades that have been sampled and identified in males among modern populations. Q-M242 is the predominant Y-DNA haplogroup among Native Americans and several peoples of Central Asia and Northern Siberia. Origins Haplogroup Q-M242 is one of the two branches of P1-M45, the other being R-M207. P1, as well as R* and Q* were observed among Ancient North Eurasians, a deeply European hunter-gatherer related population. Q-M242 is believed to have arisen around the Altai Mountains area (or South Central Siberia), approximately 17,000 to 31,700 years ago. However, the matter remains unclear due to limited sample sizes and changing definitions of Haplogroup Q: early definitions used a combination of the SNPs M242, P36.2, and MEH2 as defining mutations. Technical specification of mutation The polymorphism, “M242”, is a C→T transition resid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
