2314: Carcinization

Carcinization

Title text: Nature abhors a vacuum and also anything that's not a crab.

Explanation

This explanation may be incomplete or incorrect: Created by a CRAB. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon. If you can address this issue, please edit the page! Thanks.

As Megan is telling Cueball, separate species of animals have evolved into "crab-like" forms at different times. Naturalists who noticed the tendency gave it the name carcinization".

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. A similar process has created several varieties of river dolphin with similar adaptations to their environments, despite being 'stranded' offshoots of different forerunner pelagic species.

"True crabs" (Brachyura) form just a small subset of the Crustacea subphylum, and the Cancer genus is a subset of that, yet there appears to be something about the bodyplan and even resulting behaviour that has meant a number of species have arisen from alternate areas of the family tree that are now trivially indistinguishable without extensive study.

Carl Linnaeus even initially included all Crustacea under the 'Cancer' genus (using the Latin name for crabs), and his taxonomic classification has been heavily refined as further knowledge has come to light, in order to reveal this phenomenon.

Apparently this principle is much stronger in the webcomic than in real life, as shortly after being told this, Megan notices that Cueball (not a crustacean!) has himself turned into a crab. This isn't really evolution as we know it, which refers to gradual changes in a species across generations. What happens to Cueball is more like a transformation, but it could still be called 'carcinization', since he becomes crab-like.

Cueball's sudden transformation is perhaps explained by the title text, that "Nature abhors a vacuum and anything that's not a crab". The text is a reference to Aristotle's Horror vacui, a statement about how empty space tends to be immediately refilled by surrounding things, so vacuums seem to be impossible to maintain. As does "not being a crab", it seems.

[Cueball and Megan are walking next to each other towards the left.]

Megan: Have you heard of "Carcinization"?

Megan: The tendency of nature to evolve things into crabs.

Cueball: Oh?

[Same scene]

Megan: Yeah, the basic "crab" design has evolved separately a number of times.

Cueball: Evolution just loves making crabs, I guess!

[Narrower panel - Only Megan is seen, still walking, and appearing to shrug.]

Megan: Apparently!

[Two smaller panels, one above the other. The first panel shows Megan continuing to walk along. The second shows Megan turning and looking back to see where Cueball has gone.]

[Megan has stopped walking and is looking at a small crab scuttling along on the ground, which Cueball apparently evolved into.]

Megan: Oh no

Discussion

Honestly, what is there to explain here? The only thing I can imagine in this explanation page is an explanation of why carcinization happens, which isn't explaining the comic. 162.158.62.119 22:52, 1 June 2020 (UTC)

We might need to look at the differences between various 'false crabs' and their relatives, to show that in the false crabs' lifestyle, some crab-feature they have and their close cousinshttps://www.explainxkcd.com/wiki/index.php?title=User:Lightcaller&action=edit&redlink=1 do not is a thing that the CCs would be unable to match if they lived in the FC-like style. This is probably the subject of a whole dissertation (if not several). 141.101.107.80 00:22, 2 June 2020 (UTC)

Does this mean all programming languages evolve into Rust?172.69.68.87 23:08, 1 June 2020 (UTC)

I think this might be part of the joke here. Rust has partially replaced other programming languages in well known companies, and it has been the most beloved language for four years straight (according to StackOverflow survey). There has been many XKCDs with programming themes, I don't think Rust would go unnoticed for so long. (Note: Rust's mascot is a crab) 141.101.96.198 15:22, 2 June 2020 (UTC)

Is it just a coincidence that today's Questionable Content also contained a reference to crabs? 172.69.68.195 00:31, 2 June 2020 (UTC)

It may be of note that Qwantz (a comic previously parodied in 145) did a comic about carcinisation earlier this year 162.158.158.179 01:08, 2 June 2020 (UTC)

Why do you call Dinosaur Comic Qwantz? --Kynde (talk) 11:51, 2 June 2020 (UTC) <-- because that's the web URLCellocgw (talk) 12:36, 2 June 2020 (UTC)

Gotta say, this is the first xkcd in a while that made me laugh. Lightcaller (talk) 03:49, 2 June 2020 (UTC)

This comic was posted 3 weeks too early, seeing as Cancer doesn't start until June 21 or 22 Cellocgw (talk) 12:34, 2 June 2020 (UTC)

Looks like it already happened at one Taiwanese semiconductor company: https://en.wikipedia.org/wiki/File:Realtek_logo_vector.svg. Shamino (talk) 14:11, 2 June 2020 (UTC)

The word "evolution" predates Darwin by at least a hundred years. It means a gradual development. Darwinian descent with modification is a specific type of evolution but the term can and is used other forms of gradual development, without any implication that anything Darwinian is going on.172.69.63.241 10:08, 4 June 2020 (UTC)

This is a typical confusion of means vs ends. Evolution is a description of the results - the ends. Darwin described natural selection - a means capable of producing those ends that works well with observed data. There were, and still are theories that describe other means, which fit observations to differing degrees. Shamino (talk) 12:56, 4 June 2020 (UTC)

Webcomic Name

IMHO, it's pretty likely the last panel is a reference to webcomic name - the formatting of "OH NO" with no punctuation, no other text, the fact it's the last panel etc all seem not particularly xkcd-ish, and very webcomic name-ish. Do we really need this disclaimer " But may have nothing to do with it, since having told Cueball about this and then seeing him turned into a crab, may indicate Megan was the cause! And either way, saying "oh no" to something bad is not particular to the mentioned web comic." Stevage (talk) 13:53, 2 June 2020 (UTC)

Agreed, the rambling is not needed. Good edit. --V2Blast (talk) 19:05, 2 June 2020 (UTC)

I disagree that this is related to "webcomic name". "Oh no" doesn't necessarily relate to anything. It is unclear whether Randall is aware of or a fan of that comic. 172.69.33.203 21:57, 2 June 2020 (UTC)

I removed it. It's not even lowercase. 162.158.74.61 23:59, 2 June 2020 (UTC)

By weird coincidence yesterdays Questionable Content ended with Ancient Aliens were Crabs gag...

https://www.questionablecontent.net/view.php?comic=4276 Not sure if that's relevant, but it's at least interesting. --172.68.141.142 22:39, 2 June 2020 (UTC)

There is a clear parallel with Ionesco's Rhinoceros, even the term Rhinocerisation. 173.245.54.119 20:02, 4 June 2020 (UTC)

Am I the only one who every time he sees this comic constantly thinks of the spooky South Park song "Crab People, Crab People. Look like crabs. Talk like people"? Gunterkoenigsmann (talk) 17:17, 5 June 2020 (UTC)

I wonder if this comic might also be a reference to Karcrab, a meme about Karkat. Karkat is a character in Homestuck, which is also on Randall's list of favorite comics. Karkat is generally a very angry (and therefore crabby) alien. He wields a sickle that looks like a crab claw, and he has a lusus (basically an animal-like alien that acts like a parent) that is a crab. Since he's an alien, his crab-like attributes would lend support to the idea that crabs tend to evolve even on alien planets. Coincidence? - PsuedoBubble (talk) 02:06, 31 July 2020 (UTC)
