Most mammals have very similar skeletons, with the same number of bones in the same places, stretched or shrunk or shaped accordingly. Read More: Anteaters, the Sloth’s closest relative.The name has its etymological roots in ancient Greek, with xénos ( ξένος) meaning “foreign” or “alien” and arthron ( ἄρθρον) meaning “joint”. “ Xenarthra” literally means “strange joints”. Sloths and their cousins, the anteaters and armadillos, are part of an ancient Superorder called Xenarthra. Take a look–we bet you’ll find some interesting examples! The name Xenarthra In this list, you can find the Greek and Latin words most commonly used in systematic names, along with their English translation. Done right, these names are very useful since they can describe several features of the species in only two words. The rules Carl Linnaeus implemented are rigid, strict, and drummed into biologists at the very beginning of their studies. variegatus) and is usually descriptive and always lower case. The second part of a scientific name identifies the species (e.g. The first part of a scientific name identifies the genus, which is a taxonomic category that ranks above species and below family (e.g. Carl Von Linné by Aleksandr Roslin – Nationalmuseum press photo Linnaeus was the first to implement binomial nomenclature or the “two-term naming system” by which we refer to all fauna and flora today. The word finds its roots in the Greek language τάξις, taxis (meaning ‘order’, ‘arrangement’) and νόμος, nomos (‘law’ or ‘science’). Taxonomy is the scientific study of naming, defining, and classifying groups of biological organisms. How do species come by their scientific names?Ĭarl Linnaeus is known as the father of modern taxonomy. We can still hear echoes of this in the modern Spanish name for these animals: “ perezoso”. The first European documented naming of our furry friends comes from the Portuguese “preguiça” which in turn comes from the Latin word “ pigritia”, meaning “slow”. In most languages the name for sloth (the animal) is equivalent to some form of sloth (the attribute): slowness, lateness, indolence, or laziness–leading to centuries of stereotyping sloths as creatures lacking in competence and motivation. The illustration of a sloth from the Comte de Buffon’s ‘Histoire Naturelle’ Through its etymology, this unconstructive word goes back to its earliest meanings in Old English- (slǣwþ), which translates as “ lazy” or “ inert”. It’ll come as no surprise to anyone that the word sloth has many negative connotations. Slow and lazy across all vernacular languages Sometimes common names are not always scientifically accurate, so let’s take a look at the history of “sloth”. Portrait by François-Hubert Drouais – Musée Buffon à Montbard Undoubtly, Comte Buffon was a quite fancy man. One more defect would have made their lives impossible.” These sloths are the lowest form of existence. “Slowness, habitual pain, and stupidity are the results of this strange and bungled conformation. In 1749 the French Naturalist Georges-Lois Leclerc de Buffon described them thus: Sloths are the only animal whose common name is derived from one of the seven deadly sins. When Europeans first encountered sloths, it is fair to say they were not impressed. So what is the etymology of the word sloth? And how does its scientific and common name share the same meaning? An unfair name Thus, the etymology of a word is its origin and developmental history. Etymology is the study of words, particularly, the history of words.
