Haplogroup R (mtDNA)
Haplogroup R is a widely distributed Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of archaeogenetics of sub-Saharan Africa, sub-Saharan Africa. Haplogroup R is a descendant of the macro-Haplogroup N (mtDNA), haplogroup N. Among the R clade's descendant haplogroups are Haplogroup B (mtDNA), B, haplogroup U (mtDNA), U (and thus haplogroup K (mtDNA), K), Haplogroup F (mtDNA), F, Haplogroup R0 (mtDNA), R0 (and thus Haplogroup HV (mtDNA), HV, Haplogroup H (mtDNA), H, and Haplogroup V (mtDNA), V), and Haplogroup JT (mtDNA), JT (the ancestral haplogroup of Haplogroup J (mtDNA), J and Haplogroup T (mtDNA), T). Origin Soares et al. (2009) estimate the age of haplogroup R at roughly 50,000 to 70,000 years ago. This is consistent with an emergence in the course of the Southern Dispersal out of East A ...

Haplogroup Pre-JT (mtDNA)
Haplogroup pre-JT is a human mitochondrial DNA haplogroup (mtDNA). It is also called R2'JT. Origin Haplogroup pre-JT is a descendant of the haplogroup R. It is characterised by the mutation T4216C. The pre-JT clade has two direct descendant lineages, haplogroup JT and haplogroup R2. Distribution According to YFull MTree, haplogroup R2'JT has allegedly been sequenced in at least three individuals, among whom one came from ancient Egypt and one from modern Denmark. However, Ian Logan mutationally interpreted the Denmark sample as being a member of T1a. One carrier of haplogroup R2'JT was found in an in-depth study of "108 Scandinavian Neolithic individuals". Subclades Its major subclade is Haplogroup JT, which further divides into Haplogroup J and Haplogroup T. Its other subclade is Haplogroup R2, which has such branches as R2a, R2b, and R2c.

Human Mitochondrial DNA Haplogroup
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe. The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships. The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve. The rate at which mitochondrial DNA mutates is known as the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptolemaic Kingdom
The Ptolemaic Kingdom (; , ) or Ptolemaic Empire was an ancient Greek polity based in Ancient Egypt, Egypt during the Hellenistic period. It was founded in 305 BC by the Ancient Macedonians, Macedonian Greek general Ptolemy I Soter, a Diadochi, companion of Alexander the Great, and ruled by the Ptolemaic dynasty until the death of Cleopatra VII in 30 BC. Reigning for nearly three centuries, the Ptolemies were the longest and final Dynasties of ancient Egypt, dynasty of ancient Egypt, heralding a distinct era of Hellenistic religion, religious and cultural syncretism between Greek and Egyptian culture. Alexander the Great conquered Thirty-first Dynasty of Egypt, Persian-controlled Egypt in 332 BC during Wars of Alexander the Great, his campaigns against the Achaemenid Empire. Death of Alexander the Great, Alexander's death in 323 BC was followed by the Empire of Alexander the Great, rapid unraveling of the Macedonian Empire amid competing claims by the ''diadochi'', his closest fr ...

Lower Egypt
Lower Egypt ( ') is the northernmost region of Egypt, which consists of the fertile Nile Delta between Upper Egypt and the Mediterranean Sea, from El Aiyat, south of modern-day Cairo, and Dahshur. Historically, the Nile River split into seven branches of the delta in Lower Egypt. Lower Egypt was divided into nomes and began to advance as a civilization after 3600 BC. Today, it contains two major channels that flow through the delta of the Nile River – Mahmoudiyah Canal (ancient Agathos Daimon) and Muways Canal (, "waterway of Moses"). Name In Ancient Egyptian, Lower Egypt was known as ''mḥw'' which means "north". Later on, during Antiquity and the Middle Ages, Greeks and Romans called it ''Κάτω Αἴγυπτος'' or ''Aegyptus Inferior'' both meaning "Lower Egypt", but Copts carried on using the old name related to the north – ''Tsakhet'' () or ''Psanemhit'' () meaning the "Northern part". It was further divided into a number of regions or nomes () – '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abusir
Abusir ( ; Egyptian ''pr wsjr'' ' "the resting place of Osiris"; ) is the name given to an ancient Egyptian archaeological pyramid complex comprising the ruins of 4 kings' pyramids dating to the Old Kingdom period, and is part of the Pyramid Fields of the Memphis and its Necropolis UNESCO World Heritage Site. The pyramid complex is named after the neighbouring village of Abusir, in the markaz (county) of Badrashin, Giza. The Abusir pyramid complex is located on the Western Desert plateau at the edge of the cultivated plain, with the Giza Pyramids to its north, and Saqqara to its south, and served as one of the main elite cemeteries for the ancient Egyptian capital city of Memphis. Several other villages in northern and southern Egypt are named Abusir or Busiri. The locality of Abusir took its turn as the focus of the prestigious western burial rites operating out of the then-capital of Memphis during the Old Kingdom 5th Dynasty. As an elite cemetery, neighbou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Mummies
The ancient Egyptians had an elaborate set of funerary practices that they believed were necessary to ensure their immortality after death. These rituals included mummifying the body, casting magic spells, and burials with specific grave goods thought to be needed in the afterlife. The ancient burial process evolved over time as old customs were discarded and new ones adopted, but several important elements of the process persisted. Although specific details changed over time, the preparation of the body, the magic rituals, and grave goods were all essential parts of a proper Egyptian funeral. History Although no writing survived from the Predynastic period in Egypt (), scholars believe the importance of the physical body and its preservation originated during that time. This likely explains why people of that time did not follow the common practice of cremation among neighboring cultures, but rather buried the dead. Some of the scholars believe the Predynastic-era Egyptian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ust'-Ishim Man
Ust'-Ishim man is the term given to the 45,000-year-old remains of one of the early modern humans to inhabit western Siberia. The fossil is notable in that it had intact DNA which permitted the complete sequencing of its genome, one of the oldest modern human genomes to be so decoded. The remains consist of a single bone—left femur—of a male hunter-gatherer, which was discovered in 2008 protruding from the bank of the Irtysh River by Nikolai Peristov, a Russian sculptor who specialises in carving mammoth ivory. Peristov showed the fossil to a forensic investigator who suggested that it might be of human origin. The fossil was named after the Ust-Ishimsky District of Siberia where it had been discovered. Genome sequencing The fossil was examined by paleoanthropologists in the Max Planck Institute for Evolutionary Anthropology, located in Leipzig, Germany. Carbon dating showed that the fossil dates back to 45,000 years ago, making it the oldest human fossil to be so dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eurasia
Eurasia ( , ) is a continental area on Earth, comprising all of Europe and Asia. According to some geographers, Physical geography, physiographically, Eurasia is a single supercontinent. The concept of Europe and Asia as distinct continents dates back to classical antiquity, antiquity, but their borders have historically been subject to change. For example, the ancient Greeks originally included Africa in Asia but classified Europe as separate land. Eurasia is connected to Africa at the Suez Canal, and the two are sometimes combined to describe the largest contiguous landmass on Earth, Afro-Eurasia. History Eurasia has been the host of many ancient civilizations, including those based in Mesopotamia, Egypt, the Indus Valley and China. In the Axial Age (mid-first millennium BCE), a continuous belt of civilizations stretched through the Eurasian Subtropics, subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
