Ophioglossum, the adder's-tongue ferns, is a genus of about 50 species of ferns in the family Ophioglossaceae. The name Ophioglossum comes from the Greek meaning "snake-tongue". Their cosmopolitan distribution is mainly in tropical and subtropical habitats.
Ophioglossaceae, the adder's-tongue family, is a small family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, it is the only family in the order Ophioglossales, which together with the Psilotales is placed in the subclass Ophioglossidae. The Ophioglossidae are one of the groups traditionally known as eusporangiate ferns. Members of the family differ from other ferns in a number of ways. Many have only a single fleshy leaf at a time. Their gametophytes are subterranean and rely on fungi for energy.
Lygodium is a genus of about 40 species of ferns, native to tropical regions across the world, with a few temperate species in eastern Asia and eastern North America. It is the sole genus in the family Lygodiaceae in the Pteridophyte Phylogeny Group classification of 2016. Alternatively, the genus may be placed as the only genus in the subfamily Lygodioideae of a more broadly defined family Schizaeaceae, the family placement used in Plants of the World Online as of November 2019.
E-M215, also known as E1b1b and formerly E3b, is a major human Y-chromosome DNA haplogroup. It is a division of the macro-haplogroup E-M96, which is defined by the single-nucleotide polymorphism (SNP) mutation M215. In other words, it is one of the major patrilineages of humanity, linking from father-to-son back to a common male-line ancestor. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.
The short-nosed bandicoots are members of the order Peramelemorphia. These marsupials can be found across Australia, although their distribution can be patchy. Genetic evidence suggests that short-nosed bandicoots diverged from the related long-nosed species around eight million years ago, during the Miocene epoch, and underwent a rapid diversification around three million years ago, during the late Pliocene.
Haplogroup A is a human Y-chromosome DNA haplogroup, which includes all living human Y chromosomes. Bearers of extant sub-clades of haplogroup A are almost exclusively found in Africa, in contrast with haplogroup BT, bearers of which participated in the Out of Africa migration of anatomically modern humans. The known branches of haplogroup A are A00, A0, A1a, and A1b1; these branches are only very distantly related, and are not more closely related to each other than they are to haplogroup BT.
Haplogroup E-M96 is a human Y-chromosome DNA haplogroup. It is one of the two main branches of the older and ancestral haplogroup DE, the other main branch being haplogroup D. The E-M96 clade is divided into two main subclades: the more common E-P147, and the less common E-M75.
Haplogroup E-V38, also known as E1b1a-V38, is a human Y-chromosome DNA haplogroup. E-V38 is primarily distributed in sub-Saharan Africa. E-V38 has two basal branches, E-M329 and E-M2. E-M329 is a subclade mostly found in East Africa. E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of African Great Lakes; it also occurs at moderate frequencies in some parts of North Africa, West Asia, and Southern Europe.
The genetic history of the Middle East is the subject of research within the fields of human population genomics, archaeogenetics and Middle Eastern studies. Researchers use Y-DNA, mtDNA, and other autosomal DNAs to identify the genetic history of ancient and modern populations of Egypt, Persia, Mesopotamia, Anatolia, Arabia, the Levant, and other areas.
The Hyphodermataceae are a family of fungi in the order Polyporales. It contains the genus Hyphoderma.
Maghrebis or Maghrebians is a modern Arabic term meaning "Westerners", mainly referring to the western part of the Arab world and North Africa. Maghrebis are predominantly of Arab and Berber or mixed Arab-Berber origins.
Haplogroup E-V68, also known as E1b1b1a, is a major human Y-chromosome DNA haplogroup found in North Africa, the Horn of Africa, Western Asia and Europe. It is a subclade of the larger and older haplogroup, known as E1b1b or E-M215. The E1b1b1a lineage is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome, which is known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.
African admixture in Europe refers to the presence of human genotypes attributable to periods of human population dispersals out of Africa in the genetic history of Europe. For example, certain Y-DNA and mtDNA lineages are thought to have spread from Northeastern Africa to the Near East during the later Pleistocene, and from there to Europe with the Neolithic Revolution.
There is evidence for interbreeding between archaic and modern humans during the Middle Paleolithic and early Upper Paleolithic. The interbreeding happened in several independent events that included Neanderthals and Denisovans, as well as several unidentified hominins.
The genetic history of North Africa encompasses the genetic history of the people of North Africa. The most important source of gene flow to North Africa was from the Middle East, although the Sahara desert to the south and the Mediterranean Sea to the North were also important barriers to gene flow from sub-Saharan Africa and parts of Europe in prehistory. However, North Africa is connected to Western Asia via the Isthmus of Suez and the Sinai peninsula, while at the Straits of Gibraltar, North Africa and Europe are separated by only 15 km (9 mi), similarly Malta, Sicily, Canary Islands, and Crete are close to the coasts of North Africa.
Moroccan genetics encompasses the genetic history of the people of Morocco, and the genetic influence of this ancestry on world populations. It has been heavily influenced by geography.
The genetic history of Egypt reflects its geographical location at the crossroads of several major biocultural areas: North Africa, the Sahara, the Middle East, the Mediterranean and sub-Saharan Africa.
Haplogroup E-M2, also known as E1b1a1-M2, is a human Y-chromosome DNA haplogroup. E-M2 is primarily distributed within sub-Saharan Africa. More specifically, E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of the African Great Lakes; it also occurs at moderate frequencies in North Africa and Middle East. E-M2 has several subclades, but many of these subhaplogroups are included in either E-L485 or E-U175. E-M2 is especially common among indigenous Africans who speak Niger-Congo languages, and was spread to Southern Africa and East Africa through the Bantu expansion. The west African Jews carry this dna, as well as all other Jewish groups on their paternal side at the highest rates in comparison to European and middle eastern groups that aren’t Jewish.
The human Y-chromosome haplogroup E-V12 is a subclade of E-M78, which in turn is part of the larger haplogroup E1b1b1. According to Cruciani et al. (2007), the E-V12 sublineage likely originated in Northern Africa. It is found across Northern Africa with a strong presence in Egypt, Sudan, the Central Sahel, the Horn of Africa, and in lower frequency across the Levant, Anatolia, African Great Lakes region, and Europe.
The genetic history of Africa is composed of the overall genetic history of African populations in Africa, including the regional genetic histories of North Africa, West Africa, East Africa, Central Africa, and Southern Africa, as well as the recent origin of modern humans in Africa. The Sahara served as a trans-regional passageway and place of dwelling for people in Africa during various humid phases and periods throughout the history of Africa.
