Humans are pretty blessed in the keister department . We might not measure up in volume to say , an elephant – but in term of body to butt proportion , we ’re doing middling all-fired well for ourselves .
Buttock bulk is , of course , dependent on a soul ’s single genetic constitution , and an enthusiastic authorities ofsquattingand lunging can go some agency to boosting the rear end . However , according to theInstitute of Human Anatomy(IHA ) we still , as a species , have the biggest booties of the animal realm . Butt why ? ( Pun very much intended )
Why do humans have such big butts?
Human butts include a gluteal fold and a gluteal fissure ( that ’s the scrap down the middle ) , as IHA co - laminitis Jonathan Bennion and science laboratory conductor Justin Cottle so generously demonstrate in the below telecasting . What pretend the tissue paper between the two so generous on the human form is largely to do with how the muscle is sequester to the skeleton .
Using a real human corpse ( the kind you get atbody farms ) Bennion have us through a dissection of the buttocks ' surface physical body , beginning at the epidermis and dermis which is effectively the skin . Under here we have the hypodermis , made up of fatty tissue paper sleep with as adipose , the thickness of which is qualified on productive volume which can be determined by a person ’s lifestyle or cistron .
However , this is not the secret to humankind ’s generous behind , oh no . For that , we have thegluteus maximusto thank .
TheGladiator - sounding muscle group plays a immense character in human locomotion , connect the backbone , hip and femur together to mobilise the hip as thegluteus maximusstretch and contract . This is why growing your glutes is helped by movement such as deadlifts , which see thegluteus maximusstretch and contract to extend the hip before the tail end muscle pulls it all back to an good position .
Thegluteus maximusis forever engaged as we go about our daytime as bipedal , just animals . Unlike , as Bennion demonstrates , cats , who head for the hills around on all fours and therefore do n’t affiance the glutes in the same fashion .
The more a muscular tissue is used , the bigger it get , and so in develop to be erect animals we earned ourselves the skeletal location require to claim the openhanded butt title .
The honour was wonderfully attest in an ( albeitedited to be more bootylicious than the original ) meme about Perseus and his considerable impertinence .
And humanity has proved time and time again that it has many use for a generousgluetus maximus .
So , one curious question about the human buns tackled , but look … why do humans have butt hair ?
