Catia (gens)

The gens Catia was a plebeian family at Rome from the time of the Second Punic War to the 3rd century The gens achieved little importance during the Republic, but held several consulships in imperial times.

Origin of the gens

The Catii may have been of Vestinian origin; Gaius Catius, who served under Marcus Antonius, is said to have belonged to this ancient race. However, members of the family were already at Rome by the time of the Second Punic War, when Quintus Catius was plebeian aedile. The philosopher Catius was an Insuber, a native of Gallia Transpadana, and may have been a freedman of the gens, or perhaps his name arose by coincidence.

CATIA

CATIA (an acronym of computer aided three-dimensional interactive application) (in English, usually pronounced /kəˈtiə/) is a multi-platform computer-aided design (CAD)/computer-aided manufacturing (CAM)/computer-aided engineering (CAE) software suite developed by the French company Dassault Systèmes. It is written in the C++ programming language.

History

CATIA (Computer Aided Three-Dimensional Interactive Application) started as an in-house development in 1977 by French aircraft manufacturer Avions Marcel Dassault, at that time customer of the CAD/CAM CAD software to develop Dassault's Mirage fighter jet. It was later adopted in the aerospace, automotive, shipbuilding, and other industries.

Initially named CATI (Conception Assistée Tridimensionnelle Interactive – French for Interactive Aided Three-dimensional Design ), it was renamed CATIA in 1981 when Dassault created a subsidiary to develop and sell the software and signed a non-exclusive distribution agreement with IBM.

In 1984, the Boeing Company chose CATIA V3 as its main 3D CAD tool, becoming its largest customer.

Gens

In ancient Rome, a gens (/ˈɡɛns/ or /ˈdʒɛnz/), plural gentes, was a family, consisting of all those individuals who shared the same nomen and claimed descent from a common ancestor. A branch of a gens was called a stirps (plural stirpes). The gens was an important social structure at Rome and throughout Italy during the period of the Roman Republic. Much of an individual's social standing depended on the gens to which he belonged. Certain gentes were considered patrician, others plebeian, while some had both patrician and plebeian branches. The importance of membership in a gens declined considerably in imperial times.

Origin of the gens

The word gens is sometimes translated as "race" or "nation", meaning a people descended from a common ancestor (rather than sharing a common physical trait). It can also be translated as "clan" or "tribe", although the word tribus has a separate and distinct meaning in Roman culture. A gens could be as small as a single family, or could include hundreds of individuals. According to tradition, in 479 BC the Fabii alone were able to field a militia consisting of three hundred and six men of fighting age. The concept of the gens was not uniquely Roman, but was shared with communities throughout Italy, including those who spoke Italic languages such as Latin, Oscan, and Umbrian, as well as the Etruscans. All of these peoples were eventually absorbed into the sphere of Roman culture.

Gens (behaviour)

In animal behaviour, a gens (pl. gentes) or host race is a host-specific lineage of a brood parasite species. Brood parasites such as cuckoos, which use multiple host species to raise their chicks, evolve different gentes, each one specific to its host species. This specialisation allows the parasites to lay eggs that mimic those of their hosts, which in turn reduces the chances of the eggs being rejected by the hosts.

The exact mechanisms of the evolution and maintenance of gens is still a matter of some research. However, it is believed that in common cuckoos, gens-specific properties are sex-linked and lie on the W chromosome of the female. Male cuckoos, which like all male birds have no W chromosome, are able to mate with females of any gens, and thereby maintain the cuckoo as one species. This is not the case in other brood parasites, such as cowbirds, in which both the male and female imprint on their preferred host. This leads to speciation, such as the indigo bird, which is suggested by the fact they have a more recent evolutionary origin than their hosts.
