carcinization etymology

In a 2017 paper on carcinization in Anomura (a group of decapod crustaceans that includes hermit crabs), researchers suggested that carcinization is likely a result of corresponding internal structures of the crustaceans that evolve to have crab-like forms. But it wasn't a straightforward path after true and false crabs split. Etymology. [13][14][15][16], An exceptional form of carcinisation, termed "hypercarcinisation", is seen in the porcelain crab Allopetrolisthes spinifrons. Meaning "relating to the citizen in his relation to the commonwealth or to fellow citizens" also is from 1610s. This work is licensed under a Creative Commons Attribution-NonCommercial 2.5 License. Carcinization, or the process of becoming a crab, has been, and continues to be, a focal point of anomuran evolutionary hypoth eses. partially carcinized crabs, carcinization, and crappy headlines.

This, in turn, effected the posterior concave emargination . circumspect: [adjective] careful to consider all circumstances and possible consequences : prudent. The new genus is named after one of the world's most eminent carcinologists, the late Dr. From the dawn of life in the Archaean Eon through the . Carcinization. Terms are different, because they often has that certain etymology, like "carcinisation" was coined by L. A. Borradaile in early 20th century. The crab shape has evolved so many times the evolutionary biologist L.A. Borradaile coined the term carcinization in 1916 to describe the convergent evolution process in which a crustacean evolves into a crab-like form from a non-crab-like form. It turns out that five different groups of non-crab crustaceans have evolved into crabs in a process known as carcinization, according to a study from the Biological Journal of the Linnean Society as reported by Popular Mechanics. Crabs are decapod crustaceans of the infraorder Brachyura . This is a post of two parts: the interesting tale of convergence involving crab-like creatures, and the very poor - nay, crappy (because I like the alliteration) - headline on a popular article about it. Carcinization, or convergent evolution of crab-like morphology, is a well-known phenomenon in decapods, with crab . the Chesapeake, they sidestep, shuffling and click-clacking, tip-. Since he's an alien, his crab-like attributes would lend support to the idea that crabs tend to evolve even on alien planets. Location Vlo Canal De L'ourcq, At least thats what certain Internet memes would have you believe. their bronze-tough armor belies. This bay is ruled by crabs. Notes. Carcinisation (or carcinization) is an example of convergent evolution in which a crustacean evolves into a crab -like form from a non-crab-like form. Thats the connection between cancer and all these crab-related words. Carcinization is believed to have occurred in at least five groups of decapod crustaceans, independently, most notably king crabs which most scientists believe evolved from hermit crab ancestors. It is a specific form of convergent evolution, where differing families of animals (in this case, nominally across the crustacea) develop a tendency towards developing a 'crab' bodyplan to a greater degree than their origins would suggest. Porcelain Crabs: Though they now look distinctly crab-like, porcelain crabs may have originally begun as squat lobsters. Change), You are commenting using your Twitter account. This process has been called.

[17], Some crab shaped species have evolved away from the crab form in a process known as decarcinisation. It is far, far, far more likely to happen to an animal that already has a few crab-like characteristics. Traditional examples of carcinization in the Anomura are most celebrated among hermit crabs but certainly are not limited to this group. Evidence from larval, megalopal and early juvenile morphology", "Hermit to king, or hermit to all: multiple transitions to crab-like forms from hermit crab ancestors", "Recent advances and conflicts in concepts of anomuran phylogeny (Crustacea: Malacostraca)", "Hypercarcinisation: an evolutionary novelty in the commensal porcellanid, "How to become a crab: Phenotypic constraints on a recurring body plan", https://en.wikipedia.org/w/index.php?title=Carcinisation&oldid=1133010100, This page was last edited on 11 January 2023, at 21:06. The term was introduced by L. A. Borradaile, who described it as "one of the many attempts of Nature to evolve a crab". Carcinization is a surprisingly common evolutionary process, but it doesnt happen to all animals in all situations. The researchers concluded that multiple features of a crabs body the flat, hexagonal shape; the short abdomen; and the hard shell, among others confer physical advantages that make creatures with those features more likely to thrive. A genus of extinct mammals that lived 30-60 million years ago does have! (He isnt always for me either. The new genus is named after one of the world's most eminent carcinologists, the late Dr. What does carcinisation mean? Harper, Douglas. Research on this phenomenon can be traced back to the mid-to-late 1800's. Carcinization seems to happen a lot in nature, but it does not happen to all animals equally.

In addition to the shortened body form, A.spinifrons also shows similar sexual dimorphism to that seen in true crabs, where males have a shorter pleon than females. 1800, used by British physician Edward Jenner (1749-1823) for the technique he publicized of preventing smallpox by injecting people with the similar but much milder cowpox virus (variolae vaccinae), from vaccine (adj.) Evolution of CrabsHistory and Deconstruction of a Prime Example of Convergence. Crabs have long stumped taxonomists who have invariably misclassified species as true or false crabs due to their striking similarities. Honestly, what is there to explain here? } It seems certain that carcinisation, return to a crab-like habitus, has evolved several times in the Anomura.

The Anomura presents the greatest degree of morphological disparity in the decapod Crustacea, with body forms ranging from the symmetrical and asymmetrical hermit crabs to squat lobsters and king crabs. For example, Martin & Abele (1986) defined carcinization as the re- Noun. carcinisation noun A hypothesized process by which a crustacean evolves into a non-crab-like form Etymology: Coined by Dr. L.A.

The study discussed five documented instances in which creatures that started out as something else all managed to evolve to display much more crab-like forms. He has a crab like species as the chief competitor to humans in his Polity universe. < /a > carcinization: an evolutionary reality infraorder Brachyura and were! The ventral vessel system, on the other hand, which mainly supplies the limbs, differs significantly between the taxa, with pagurids displaying the plesiomorphic condition. For example: most hermit crabs are asymmetrical, so that they fit well into spiral snail shells; the abdomens of king crabs, even though they do not use snail shells for shelter, are also asymmetrical.
