Yes , everyone poops . Moreover , at least when it come to mammals , everyone poops for about the same amount of metre , according to a new study . The research , described in the journalSoft Matterand brought to our attention by theScience of Us , examined mammal as little as cats and as expectant as elephants , get hold that they all take around 12 seconds to defecate .
The study test elephants , elephantine pandas , and warthogs at the Zoo Atlanta , dogs at a park , the dimensions of dejection and large intestines , and numerical models to better infer how animals poop . The Georgia Institute of Technology researchers found that regardless of the fauna ’s full size , the mammals analyze had stool that were double the length of their rectum , and whether that rectum was an inch - and - a - half foresightful or almost 16 inches long , their feces take about 12 seconds to exit the body .
The researchers only studied beast with cylindrical feces ( exclude rabbits , gnawer , and ruminants like cattle in the outgrowth ) , collecting stool samples from 34 zoological garden animal , seven farm animals , and two coinage of animals ( nameless ) living at Georgia Tech . They also observed brute pooping at Zoo Atlanta firsthand and watched 19 different YouTube videos that feature brute doing their commercial enterprise .
Through their reflexion and theoretical calculations on the fluid mechanics of laxation , the research worker found that all animals exert the same amount of pressure while pooping . They also find that bigger animals had more crap to get free of , but they also had thicker mucous secretion layers line the walls of their large intestine , which helps move the poop out of the body at a faster clip . coalesce these two factors , and you get pretty uniform poop duration across the animate being kingdom—12 second — despite the all-embracing grasp of torso sizes . ( Constipation happens when the ordure travel through the large intestine douse up that mucus level . Think of it like trying to go down a waterslide that is completely dry . )
This study did not examine every animal on Earth , but the finding is in pedigree with research on the other potty habit of mammals . Previous work — awarded anIg Nobel Prizein 2015 — found that all mammalian puddle for about the same amount of metre ( 21 seconds ) . It ’s evolutionarily plausible , too . Pooping make it hard to go away from predators ( a important number ofslothsdie when they go away the treetopsto poopat ground level , in fact ) and a quick raise - ho of the bowels is safer than straining in one location for 20 second .
The research worker go for their study will be used for more than just satisfying the curiosity of Aspinwall obsessives , though . “ By understanding the physics of defecation , we will provide not only new ideas for aesculapian diagnostics , nappy , and incontinence products but also raptus methods for the BM of humans , dearie , and agriculturally important fauna , ” they save .
