Hypargos (bird)
''Hypargos'' is a genus of small seed-eating birds in the family Estrildidae that are found in Sub-Saharan Africa. There are species with the common name of twinspot in other genera within the Estrildidae family. Taxonomy The genus ''Hypargos'' was introduced in 1862 by the German naturalist Ludwig Reichenbach to accommodate the pink-throated twinspot. The name combines the Ancient Greek ''hypo'' meaning "beneath" with ''Argos'' from Argus Panoptes, the many-eyed giant in Greek mythology. The genus ''Hypargos'' is sister to the genus ''Euschistospiza ''Euschistospiza'' is a genus of birds in the family Estrildidae, found in Sub-Saharan Africa Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara.

Argus Panoptes
Argus or Argos Panoptes ( grc, Ἄργος Πανόπτης, All-seeing Argos) is a many-eyed giant in Greek mythology. Mythology Argus Panoptes (), guardian of the heifer-nymph Io and son of Arestor and probably Mycene (in other version son of Gaia), was a primordial giant whose epithet ''Panoptes'', "all-seeing", led to his being described with multiple, often one hundred, eyes. The epithet ''Panoptes'' was applied to the god of the Sun, Helios, and was taken up as an epithet by Zeus, ''Zeus Panoptes''. "In a way," Walter Burkert observes, "the power and order of Argos the city are embodied in Argos the neatherd, lord of the herd and lord of the land, whose name itself is the name of the land."The epithet ''Panoptes'', reflecting his mythic role, set by Hera as a very effective watchman of Io, was described in a fragment of a lost poem '' Aigimios'', attributed to Hesiod: In the 5th century and later, Argus' wakeful alertness was explained for an increasingly literal cu ...

Male Pink-throated Twinspot 2014 10 19 0374
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810 and, eight years later in 1818, he the now Professor became an instructor before, in 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years.

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa.
