Of course, the meme itself can be more or less pinpointed (Knowyourmeme contributors, 2020) but it’s building on a scientific fact that was definitely not new at all. As it’s often the case, it’s hard to pin down to a single cause, but I guess the extensive study of carcinization has to do with it. Carcinization sounds like something about prison at first blush, but on second look, . And they do resemble mammals, but they're not. Or, as a famed zoologist, L. A. Borradaile, explained the concept decades ago, "one of the many attempts of Nature to evolve a crab," according to . Abstract. Earlier this week, the internet rekindled its fascination with carcinization, a well-documented phenomenon where animals that are definitely not crabs somehow keep evolving into crab-like beings. 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.The term was introduced into evolutionary biology by L. A. Borradaile, who described it as one of the many attempts of Nature to evolve a crab. A micro-computer tomography and computer-aided 3D reconstruction-based comparison between the various crab-like taxa shows that amazingly similar structural coherences exist across all these lineages between the external characters of the crab-like habitus and internal characters. Your examples are not those of new organs, just old organs that have been reshaped to serve a different function, in this case the original function. . The majority of squat lobsters are found in deeper waters and have very long claws that can be twice as long as their bodies. For example, a planet like Naboo in Star Wars—which has land, bodies of water, rock, etc.—could be home to crabs, Wolfe said. Carcinization is where things slowly evolve into crab-like beings.

Carcinization sounds like something about prison at first blush, but on second look, you'll see it shares a root with carcinogen as well as cancer itself—both from the Greek root karkinos meaning crab. The evolution of decapod crustaceans into true crabs. What does carcinisation mean? Generally speaking, convergent evolution means that two organisms independently evolve a feature or set of features that were not present in a common ancestor, or that these features occur in different epochs in time.

This book 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. Convergent evolution is common in the animal world and there are even examples within and across Phyla. Carination definition is - the quality or state of being carinate. Download Full PDF Package. 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 is a type of convergent evolution that occurs when a non-crab-like crustacean evolves into a crab-like form. carcinization) and into possible structural dependences (i.e. For example, marsupials have relatively similar features, including hair, hands, and feet with relatively similar digits. The internet has rediscovered carcinization: the separate, five-time evolution of crabs. II.

One of the many attempts of Nature to evolve a crab (Borradaile, 1916; McLaughlin & Lemaitre, 1997). To Blackstone (1989) hermit crabs became carcinized through broadening of the carapace and reduced shell-inhabiting. Of course, convergent evolution is not that rare. The parallel evolution is the one known as carcinization. to evolve into crabs.

"This book brings together a collection of studies from international researchers who demonstrate the brain's remarkable capacity to adapt its representation of the visual world in response to changes in its environment."--BOOK JACKET. 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 xkcd: Carcinization Carcinization is the process by which a crustacean evolves into a crab-like form. The zodiacal symbol for the cancer sign is a crab. For instance, the relevant xkcd mentions that (Explainxkcd contributors, 2021): Evolution just loves making crabs, I guess! Within decapod crustaceans, Anomura is the phenotypically most disparate taxon, ranging from hermit crabs to squat lobsters to crab-like representatives. Carcinization, or the process of becoming a crab, has been, and continues to be, a focal point of anomuran evolutionary hypotheses. Potential pathways of carcinization are exam-ined from perspectives of adult morphology in the Paguroidea, Galatheoidea . Carcinization is typically offered up as an example of convergent evolution, where similar features evolve independently among different species (such as flight independently evolving in birds, insects, and bats).
