So how come that our asses evolved to the point that in case somebody does not wipe properly they are gonna wake up with smelly fingers? All this extra effort while most animals are just going on with their lives after taking a dump without any rashes or ichyness. What are the evolutionairy benefits for this behaviour if there is any ?
In: Biology
There’s a couple different reasons for this. One, we stand upright and this requires larger and more substantial glute muscles to accommodate our bipedal structures. Two our diets are far different than they were when we first evolved to walk upright. The foods we eat now cause us to produce much sloppier bowel movements thus requiring extra cleaning to keep our backsides clean.
