Danaea Sellowiana
''Danaea'' is a fern genus of approximately 50 species in the eusporangiate fern family Marattiaceae. They are small to intermediately large ferns with erect or creeping rhizomes and usually once-pinnate leaves with opposite pinnae. The fertile leaves are contracted, acrostichoid and covered below with sunken, linear synangia. The genus ''Danaea'' has a neotropical distribution, occurring from southern Mexico through Central America, the Caribbean and northern South America to Bolivia, Paraguay and the Mata Atlantica in Brazil and Northern Argentina. There is also a population on Isla del Coco (Cocos Island) in the Pacific. The genus name of ''Danaea'' is named after the Greek mythology, Danaë, an Argive princess and mother of the hero Perseus by Zeus. Two species ''Danaea carillensis'' (Costa Rica) and ''D. simplicifolia'' (Guianas, Brazil, Trinidad) have simple, undivided leaves, and some other species sometimes have bipinnate leaves (''D. atlantica, D. bipinnata, D. nod ...

Isla Del Coco
Cocos Island ( es, Isla del Coco) is an island in the Pacific Ocean administered by Costa Rica, approximately southwest of the Costa Rican mainland. It constitutes the 11th of the 13 districts of Puntarenas Canton of the Province of Puntarenas. With an area of approximately , the island is more or less rectangular in shape. It is the southernmost point of geopolitical North America if non-continental islands are included. The entirety of Cocos Island has been designated a Costa Rican National Park since 1978, and has no permanent inhabitants other than Costa Rican park rangers. Surrounded by deep waters with counter-currents, Cocos Island is admired by scuba divers for its populations of hammerhead sharks, rays, dolphins and other large marine species. The wet climate and oceanic qualities give Cocos an ecological character that is not shared with either the Galápagos Archipelago or any of the other islands (for example, Malpelo, Gorgona or Coiba) in the eastern Pacifi ...

Fossils
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Lineage (evolution)
An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant.The Oxford English Dictionary defines biological lineage as "a sequence of species each of which is considered to have evolved from its predecessorOED definition of lineage/ref> Lineages are subsets of the evolutionary tree of life.

Kalevala
The ''Kalevala'' ( fi, Kalevala, ) is a 19th-century work of epic poetry compiled by Elias Lönnrot from Karelian and Finnish oral folklore and mythology, telling an epic story about the Creation of the Earth, describing the controversies and retaliatory voyages between the peoples of the land of Kalevala called Väinölä and the land of Pohjola and their various protagonists and antagonists, as well as the construction and robbery of the epic mythical wealth-making machine Sampo. The ''Kalevala'' is regarded as the national epic of Karelia and Finland and is one of the most significant works of Finnish literature with J. L. Runeberg's ''The Tales of Ensign Stål'' and Aleksis Kivi's ''The Seven Brothers''. The ''Kalevala'' was instrumental in the development of the Finnish national identity and the intensification of Finland's language strife that ultimately led to Finland's independence from Russia in 1917. The work is also well known internationally and has partly inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Epic
A national epic is an epic poem or a literary work of epic scope which seeks or is believed to capture and express the essence or spirit of a particular nation—not necessarily a nation state, but at least an ethnic or linguistic group with aspirations to independence or autonomy. National epics frequently recount the origin of a nation, a part of its history, or a crucial event in the development of national identity such as other national symbols. History In medieval times Homer's ''Iliad'' was taken to be based on historical facts, and the Trojan War came to be considered as seminal in the genealogies of European monarchies. Virgil's ''Aeneid'' was taken to be the Roman equivalent of the ''Iliad'', starting from the Fall of Troy and leading up to the birth of the young Roman nation. According to the then prevailing conception of history, empires were born and died in organic succession and correspondences existed between the past and the present. Geoffrey of Monmouth ...

Lesser Antilles
The Lesser Antilles ( es, link=no, Antillas Menores; french: link=no, Petites Antilles; pap, Antias Menor; nl, Kleine Antillen) are a group of islands in the Caribbean Sea. Most of them are part of a long, partially volcanic island arc between the Greater Antilles to the north-west and the continent of South America."West Indies." ''Merriam-Webster's Geographical Dictionary'', 3rd ed. 2001. () Springfield, MA: Merriam-Webster Inc., p. 1298. The islands of the Lesser Antilles form the eastern boundary of the Caribbean Sea where it meets the Atlantic Ocean. Together, the Lesser Antilles and the Greater Antilles make up the Antilles. (Somewhat confusingly, the word Caribbean is sometimes used to refer only to the Antilles, and sometimes used to refer to a much larger region.) The Lesser and Greater Antilles, together with the Lucayan Archipelago, are collectively known as the West Indies.

Danaea Kalevala
''Danaea kalevala'' is a species of fern belonging to the family Marattiaceae. It is endemic to rainforests of the Lesser Antilles islands in the Caribbean. This includes the islands of: Saint Kitts, Guadeloupe, Dominica, Martinique, Saint Vincent, and Grenada. Description ''Danaea kalevala'' plants are large, up to tall. They have radially arranged creeping rhizomes to thick and pinnate leaves. The pinna apices are finely denticulate. ''Danaea kalevala'' was named by Dutch botanist Maarten Christenhusz in honor of Finland, his host country. The ''Kalevala'' is the Finnish people's heroic epic and national reference. Distribution In the wild ''Danaea kalevala'' is rare. On the type locality along Trace des Jésuites, in Martinique, only five plants were found in 2003. Even though the species is not uncommon in southern parts of Guadeloupe, from most other islands the plants are only known from old collections. The species is thus endangered. This species cannot be cultivat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perseus
In Greek mythology, Perseus (Help:IPA/English, /ˈpɜːrsiəs, -sjuːs/; Greek language, Greek: Περσεύς, Romanization of Greek, translit. Perseús) is the legendary founder of Mycenae and of the Perseid dynasty. He was, alongside Cadmus and Bellerophon, the greatest Greek hero and slayer of monsters before the days of Heracles. He beheaded the Gorgon Medusa for Polydectes and saved Andromeda (mythology), Andromeda from the sea monster Cetus (mythology), Cetus. He was the son of Zeus and the mortal Danaë, as well as the half-brother and great-grandfather of Heracles (as they were both children of Zeus, and Heracles' mother was descended from Perseus). Etymology Because of the obscurity of the name "Perseus" and the legendary character of its bearer, most etymologists presume that it might be pre-Greek; however, the name of Perseus's native city was Greek and so were the names of his wife and relatives. There is some idea that it descended into Greek from the Proto-Indo-Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
