Peștera Cu Oase
Peștera cu Oase (, meaning "The Cave with Bones") is a system of 12 karstic galleries and chambers located near the city Anina, in the Caraș-Severin county, southwestern Romania, where some of the oldest European early modern human (EEMH) remains, between 37,000 and 42,000 years old, have been found. While "Oase 1" lower jaw is fully mature, the facial skeleton is that of a mid-second-decade adolescent, therefore corresponding to a second individual, designated as "Oase 2". Further analyses have revealed that the left temporal bone represents a third individual, assessed as adolescent versus mature female, designated as "Oase 3". However, additional finds and work have shown that the temporal bone derives from the same cranium as the "Oase 2" facial and parietal bones.Trinkaus, E., Zilhão, J., Rougier, H., Rodrigo, R., Milota, S., Gherase, M., Sarcinã, L., Moldovan, O., Bãltean, I., Codrea, V., Bailey, S.

Anina
Anina (; German: ''Steierdorf''; Hungarian: ''Stájerlakanina'') is a town in the Banat region of Romania, in Caraș-Severin County, with a population of 10,886 in 2000. The town administers one village, Steierdorf (German: ''Steierdorf'', Hungarian: ''Stájerlak''). Geology In 2002, the oldest modern human remains in Europe were discovered in a cave near Anina. Nicknamed ''"Ion din Anina"'' (John of Anina), the remains (the lower jaw) are some 40,000 years old. Anina represents one of the most important localities in the South Carpathians for Jurassic fossils, both plants and animals, as the geological heritage here is particularly diverse and well preserved (Popa, 2001, 2005). Anina is a fossil-Lagerstatte for Early Jurassic biota, the Hettangian-Sinemurian terrestrial Steierdorf Formation recording an extremely rich floral association, vertebrate and invertebrate tracks, traces and burrows. This paleontological heritage was uncovered also by significant mining works, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Telugu People
Telugu people ( te, తెలుగువారు, Teluguvāru), or Telugus, or Telugu vaaru, are the largest of the four major Dravidian ethnolinguistic groups in terms of population. Telugus are native to the Indian states of Andhra Pradesh, Telangana and the Yanam district of Puducherry. A significant number of Telugus also reside in the surrounding Indian states of Karnataka, Tamil Nadu, Maharashtra, Gujarat, West Bengal, Chhattisgarh, Kerala, and Odisha, as well in the union territory of Andaman and Nicobar Islands. Telugus claim descent from the Andhras, from whom the Telugus inherit their ethnonym. Telugu is the fourth most spoken language in India and the 15th most spoken language in the world. Andhra was mentioned in the Sanskrit epics such as Aitareya Brahmana (by some estimates c. 800 BCE). According to Aitareya Brahmana of the Rigveda, the Andhras left North India from the banks of river Yamuna and migrated to South India. They are mentioned at the time of the d ...

Haplogroup NO
Haplogroup NO (M214/Page39; F176/M2314; CTS5858/M2325/F346; CTS11572), also known as NO-M214 and NO1, is a human Y-chromosome DNA haplogroup. NO is the sole confirmed subclade of Haplogroup K2a1 (K-M2313), which is the sole subclade of Haplogroup K2a (K-M2308).G. David Poznik et al., 2016, "Punctuated bursts in human male demography inferred from 1,244 worldwide Y-chromosome sequences" ''Nature Genetics'' no. 48, pp. 593–599.

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'-Ishim 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 dated. Scie ...

Haplogroup K2a (Y-DNA)
Haplogroup K2a (M2308, Z4842) is a human Y-chromosome DNA haplogroup. K2a is a primary subclade of haplogroup K2 (M526), which in turn is a primary descendant of haplogroup K (M9). Its sole primary descendant is haplogroup K-M2313 (M2313, Z4858 S11799). K-Y28301. Three living individuals in India have been found to carry K-Y28299* or K-Y28301. (As of 2018, ISOGG had not incorporated K-Y28299 or K-Y28301.) * ISOGG alone lists a haplogroup known only as "NO1~" identified by the SNP CTS707/M2306, as a sibling of NO-M214. (Under the taxonomic conventions used by ISOGG, a tilde indicates a distinct haplogroup, the position of which in the phylogeny is as yet unclear.) NO1~ is likely a primary branch of either K-M2313 or NO-M214, because, as of 2018, YFull regards CTS707/M2306 as synonymous with M214/PAGE39/PAGES00039, and yet NO1~ is also ''not'' (according to ISOGG) ancestral to either Haplogroup N (M231) or Haplogroup O (M175).

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 mitochon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Y-DNA Haplogroup
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non- recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs). The human Y-chromosome accumulates roughly two mutations per generation. "one mutation in every 30 million base pairs" Y-DNA haplogroups represent major branches of the Y-chromosome phylogenetic tree that share hundreds or even thousands of mutations unique to each haplogroup. The Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived roughly 236,000 years ago in Africa. By examining other bottlenecks most Eurasian men (men from populations outside of Af ...

Basal Eurasian
Basal Eurasian is a hypothetical lineage of anatomically modern humans with reduced, or zero, archaic hominin (Neanderthal) admixture compared to other ancient non-Africans. Basal Eurasians may originate from the Middle East or North Africa, and are said to have contributed ancestry to various West Eurasian, South Asian, and Central Asian groups. This hypothetical population was proposed to explain the lower archaic admixture among modern West Eurasians compared with East Eurasians, although alternatives without the need of such Basal lineage exist as well. Description A study by Lazaridis et al. in 2014 demonstrated that modern Europeans can be modelled as an admixture of three ancestral populations; Ancient North Eurasians (ANE), Western Hunter-Gatherers (WHG), and Early European Farmers (EEF). This same study also showed that EEFs harbour ancestry from a hypothetical 'ghost' population which the authors name 'Basal Eurasians'. This group, who have not yet been sampled from ...

East Asian
East Asia is the eastern region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. China, North Korea, South Korea and Taiwan are all unrecognised by at least one other East Asian state due to severe ongoing political tensions in the region, specifically the division of Korea and the political status of Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are among the world's largest and most prosperous economies. East Asia borders Siberia and the Russian Far East to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To the east is the Pacific Ocean and to the southeast is Micronesia (a Pacific Ocean island group, class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomically Modern Human
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of s ...

Introgression
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species. Introgression also differs from simple hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome.
