Extant taxon

The adjective tart [ retsɛnt ] denotes current or recent past states or processes.

Word origin and meaning

The word comes from the Latin tart recens for " just recently, fresh". It was in this sense until the 19th century foreign word from everyday language, much like the modern English recent and recently, " ultimately, recently, recently, recently, recently ." ( For the German " tart " in English would rather " extant " position. )

Today it is only technical language in use:

In the context of the evolution of earth and life, culture and the like for processes and phenomena occurring at the present time or may have occurred in the recent or more recent past,
In the language of science generally in terms of " fresh" ( recent track, recent traces of archaeological finds and the like)
In general practice for recent past infections and injuries; in psychoanalysis for recent past mental impressions,
In pharmacy for freshly prepared preparations ( recenter paratum ).
Culinary, particularly in relation to cheese, it means spicy, spicy, spicy, hearty or rich.

Biology

In biology tart means " living in the present time or recently extinct ". As extant species thus refers to all those who in the geological present, the Holocene (beginning 12,000 years ago up to the present time), occur or became extinct during this time. Those species that became extinct Holocene before or during the transition from the Pleistocene are called fossil. The limit of 12,000 years is just a guideline, since the extinction event at the climate change on the border from the Pleistocene to the Holocene ( the last ice age ) several thousand years lasted and geographically not expired just as fast. Frequently, therefore, also an age of 10,000 years is reported for the limit of fossil includes recently.

Earth sciences

In geology tart means: " in the present, taking place or formed under present conditions ." The opposite forms - as in biology - the term fossil, which refers to ancient Royal. For the border area, which is to put in the time of transition from the Pleistocene to the Holocene ( about 12,000 years ago, that is, towards the end of the last ice age ), the terms have established subrezent and subfossil. However, a common definition does not exist.

Mineralogy and soil science use the term analogy.

Cultural Studies

Cultural studies use the term as biology. One speaks in sociolinguistics as of extant language, comprising both living languages and those that are still spoken in recent history, in contrast to the ancient, traditional as classical education language languages ( such as Greek, Latin, Sanskrit ), and the historical, the are extinct ( Gothic, Hittite, Coptic ), or absorbed into their development in other languages ( Old High German).

Similarly, the term is used in anthropology for other cultural achievements, such as customs, artistic expression, religious rite and the like.
