Rotating locomotion in living systems – the use of wheels and propellers by organisms – has long been pondered among biologists and writers of speculative fiction. Rolling and wheeled creatures have appeared in the legends of many cultures. While other human technologies, like wings and lenses, have common analogues in the natural world, and several species are able to roll, structures that propel by rotating relative to a fixed body are represented only by the corkscrew-like bacterial flagella. Macroscopic organisms have apparently never evolved wheels, and this is attributed to two main factors: limitations of evolutionary and developmental biology, and disadvantages of wheels, when compared with limbs, in many natural environments. Wheels, beyond the molecular scale, may not be within the reach of natural evolution, and may be infeasible to grow and maintain with biological processes. Compared with limbs, they are often less energy-efficient, less versatile, and less capable of traversing or avoiding obstacles. These environment-specific disadvantages of wheels also explain why some historical civilizations abandoned them.

Improbable Lobster posted:A scene was cut in which Freddy Krueger calls protagonist Nancy Thompson "a friend of the family". [26] The scene was cut amidst a great deal of protest on the part of Craven and the producers, however the studio refused to let the movie go to screen with the slur intact. [27][28][30] It was uncommon in the 1980s for white characters to be referred to by these terms. [citation needed] looks like someone deleted this part of film history

quote:Hardee was once questioned by Special Branch officers after being found on the balcony outside government minister Michael Heseltine's hotel room, wearing nothing but a pair of socks and a leather coat containing £5,200 in cash and a pack of pornographic playing cards. He had mistaken the room for that of a friend.

You can't have wheels on a living creature because you can't transfer blood, etc through a rotating coupling made of bone

Sagebrush posted:You can't have wheels on a living creature because you can't transfer blood, etc through a rotating coupling made of bone the wheels could just be solid bone that grows and then partially detaches as the animal matures. maybe a full bone driveshaft even. it wouldn't be able to handle wear, tho, unless it molts and regrows its wheels periodically i would guess it hasn't happened for the same reason we don't drive cars around in the wilderness: wheels are only energetically favorable on flat, level, solid terrain with decent friction to avoid slippage. and they can't quickly start, stop, or change direction with any efficiency. so idk what kind of animal could use them. maybe a long-distance migratory turtle in the american south-west?

FMguru posted:the other issue is that its hard to see evolution selecting for the intermediate states that would precede a wheel. i mean, you imagine a clump of cells that work about 10% as well as an eye (can still detect motion and light/dark changes, useful for catching prey and avoiding predators). but what utility does something that is 10% of the way to a wheel bring to a creature? yea, but most of the crazy adaptations in nature didn't evolve by a direct selective path, the intermediate steps come from previous features that get repurposed to respond to new selective pressures. so maybe an armadillo-type thing has some round boney protrusions around its feet for protection, or just as a useless piece of flair that attracts a mate. a freak gets born with protrusions that are weak and prone to breaking in a way that makes them rotationally independent. when they break they rub along the ground and spin a bit as he walks, and this makes them wear evenly into a very round shape. the animal learns he can take a running start and then coast for long periods by resting on his spinny round bone spurs. maybe he can even pump his feet just right to keep up momentum. of course, all the lady armadillos go wild for a guy with his own set of wheels

The lyrics describe the effect on the mental health of an individual after a break-up. The main character seems to be addressing an ex-girlfriend, and describes his descent into madness after she has left him. However, the last verse of the song alludes to his dog running away although it could be an allegory for how he sees her.

In 2009, Bettendorf, Iowa amended its city ordinance regarding illegal inhalants to include organic substances.[34][35] In 2010, an apartment building in Fort Pierce, Florida was condemned after police found leaking containers of human waste in a unit. One police official speculated the tenant was manufacturing jenkem.

The Big Word posted:was gonna mention this. (the wheels aren't a part of the animal's body, they're melon husks or something that attach to a slot on their hooves or whatever and the plants and animals in question specifically evolved together to have this symbiotic relationship, I think that's it I haven't read that book in like 15 years) they also rely on a system of weird uh volcanic(?) features that make up paved roads for them kind of improbable if there is no god eh pullman?

The Big Word posted:lmao I forgot about the roads. that dimension was wild. and iirc the central metaphysical conceit of that series was "dark matter is actually really smart and it wants to be our friend" (and I think there was something about it guiding the wheelie dudes' evolution maybe?), like it was more a critique of religious authority than faith itself yeah i picked it up but haven't started yet it's a prequel but apparently book 5 won't be actual wikipedia so is not derail posted:The Secret Commonwealth[edit]

There was, however, opposition to the campaign in its present form, which essentially calls for the modification of the proposition to reduce the region of the proposed protection from the Post 1974 'administrative' County of Cumbria - which incorporates Cumberland, Westmorland, and Lancashire 'north of the Sands' but without abolishing the original counties - to the Traditional County of Cumberland, on native grounds, with provisions including the native right for natives to continue to manufacture the sausage elsewhere.

By 1915, it was said that "without doubt" the organization's existence scared away potential horse thieves, as evidenced by the decreasing number of thefts of horses and increasing number of automobile thefts.[20] President George F. Joyce proposed changing the purpose of the organization to those who steal automobiles and auto parts.[21] In 1921[22] and 1924,[23] the Society was still debating whether to turn its attention to car thieves. In 1925 no horses were stolen, but a cow was recovered.[24] In 1932, it was proposed that a Society in Dedham for Apprehending Hit-and-Run Drivers would be a good successor organization.[25] It was also predicted that by 2032, when human flight would be common, that there would be a Society for Apprehending Reckless Aviators over Dedham.[25] A newspaper in West Virginia once suggested that the Society not only turn its attention to catching auto thieves, but anarchists as well.[26]
