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
guess youve never seen a dog or cat lick their own bottom. most primates clean their bottoms.
a contributing factor is the modern diet and toilet. our ancestors had different diets which made “cleaning up” less of a need and squatting in a field had a much different position than sitting on the modern toilet
