How Did Human Butts Evolve to Look That Way?

Every Tuesday this month @massivesci will be publishing an article about the butt. Welcome to #ButtMonth. Today, @darcy_shapiro on why human butts even look like that. Featuring art from @melissa_k_nigro https://t.co/U1plWTb3Dz

Even if you think you have a flat butt, it's certainly rounder than most other animals outside of homo sapiens. That Corgi is cute, but its butt is all hair. A cat will gladly show you its anus, which is right at the surface, like most animals. So why do humans develop round buttocks? It wasn't for sitting.

Take a look around the animal kingdom. Even our closest living relatives among the great apes (chimpanzees, bonobos, and gorillas), don’t have proportionally as big butts as humans do. The main reason for this probably comes down to our unique style of locomotion. We’re the only mammals alive today whose primary way of getting around is walking on two legs. And becoming upright bipeds has had some important consequences for our derrières.

But(t) it's not just standing up that makes those big muscles necessary. The mechanics involved in walking on two legs meant we had to bulk up the butt. Read how at Massive Science. -via Damn Interesting

Look around. Most mammals have a butt, divided into two cheeks. And if they could stand on 2 legs, their butts would stick out farther than human's. Also common to almost all animals: mouth, nose, 2 eyes, 2 ears, food goes in one end and out the other. We are more alike than we are different, in a physical sense.

Experts say we evolved all the body parts we have, working perfectly with everything else inside our body. But they can't answer "why would a universe without intelligent design or agency, suddenly decide to make anything?" Where does a dead universe with no agency suddenly get the motivation to start making organisms, or more important, organisms capable of advanced language and advanced structures (humans)? How come Lions and Tigers and Bears and Dogs and Sharks and Elephants - pick any apex predator you want - humans are the only apex predator to have a evolutionary path towards advanced language and advanced structures? Where is the fossils definitively showing the slow evolutionary path of the human eye? the stomach? the intestines? the lungs? The answer is that they'll never be able to demonstrate the evolutionary path of the human eye. If everything is evolving to save itself, how come 99% of all organisms ever to live on earth are extinct (Source: Wikipedia)? Don't get me wrong I'm all for being open-minded and learning from outside sources. But people are far too quick to accept that evolution is fact when its still a theory (and will always be a theory). If evolution is fact, and a dead universe can evolve things, where would a dead universe get the motivation to evolve anything for the good of anything? ¯\_(ツ)_/¯
