@lucacadamo Sharks will often be followed around by schools of small fish that eat crud off their skin.
Humans consequently evolved to have extremely flexible and precise manipulators (reinforced by tool use and carrying ability) which just makes us good at "cleaning" all animals.
@lucacadamo It's a reaction to being groomed/cleaned, animals have probably been cleaning one another long before they'd even made it onto land. A pleasant reaction to being groomed results in being cleaner, less infections from parasites, and thus gets positively reinforced in evolution.
