<i>Platonia</i> species of plant

Platonia insignis, the sole species of the genus Platonia, is a tree of the family Clusiaceae native to South America in the humid forests of Brazil, Paraguay, parts of Colombia and northeast to Guyana; specially in Amazon Rainforest. Common names include bacuri, maniballi, naranjillo and bacurizeiro.

In Julian Barbour's book The End of Time: The Next Revolution in Our Understanding of the Universe, Platonia is the name given to his hypothetic entity of a timeless realm containing every possible "Now" or momentary configuration of the universe.

In the platonia dilemma introduced in Douglas Hofstadter's book Metamagical Themas, an eccentric trillionaire gathers 20 people together, and tells them that if one and only one of them sends him a telegram by noon the next day, that person will receive a billion dollars. If he receives more than one telegram, or none at all, no one will get any money, and cooperation between players is forbidden. In this situation, the superrational thing to do is to send a telegram with probability 1/20.

Virus classification is the process of naming viruses and placing them into a taxonomic system. Similar to the classification systems used for cellular organisms, virus classification is the subject of ongoing debate and proposals. This is mainly due to the pseudo-living nature of viruses, which is to say they are non-living particles with some chemical characteristics similar to those of life, or non-cellular life. As such, they do not fit neatly into the established biological classification system in place for cellular organisms.

Lark family of birds

Larks are passerine birds of the family Alaudidae. Larks have a cosmopolitan distribution with the largest number of species occurring in Africa. Only a single species, the horned lark, occurs in North America, and only Horsfield's bush lark occurs in Australia. Habitats vary widely, but many species live in dry regions.

Thrush (bird) family of passerine birds

The thrushes are a family, Turdidae, of passerine birds with a worldwide distribution. The family was once much larger before biologists determined the subfamily Saxicolinae, which includes the chats and European robins, were Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family.

Apodiformes order of birds

Traditionally, the bird order Apodiformes contained three living families: the swifts (Apodidae), the treeswifts (Hemiprocnidae), and the hummingbirds (Trochilidae). In the Sibley-Ahlquist taxonomy, this order is raised to a superorder Apodimorphae in which hummingbirds are separated as a new order, Trochiliformes. With nearly 450 species identified to date, they are the most diverse order of birds after the passerines.

Gavialidae family of reptiles

Gavialidae is a family of reptiles within the order Crocodilia. Gavialidae have conventionally consisted of only one surviving species, the gharial, which is native to India and Nepal. Many extinct species are also known. The false gharial has usually been thought to be a member of the family Crocodylidae based on several characters including skull morphology, but has sometimes been viewed as a member of this family due to general similarities in morphology and habit. However, numerous molecular studies have consistently shown the two species to be very closely related, supporting the view that they are in the same family.

Clusiaceae family of plants

The Clusiaceae or Guttiferae Juss. (1789) are a family of plants including 13 genera and ca 750 species,. Several former members of Clusiacae are now placed in Calophyllaceae and Hypericaceae. They are mostly trees and shrubs, with milky sap and fruits or capsules for seeds. The family is primarily tropical. More so than many plant families, it shows large variation in plant morphology. According to the APG III, this family belongs to the order Malpighiales.
