Do other mammals have similar amounts of nose hairs to humans? I feel like I've seen nary a nose hair in another animal's nose by picture, pet, zoo.
Possible interpretations that I'd like for you to weigh in on:
-We have the same amount it's just that humans have them closer to the exit of the nose. Possibly because we have dextrous fingers? :)
-We have more because we lack turbinates. And why is that? Our ancestral need to distance walk/run? What does that say about our evolutionary climate?
-Does it say anything about the specific evolutionary environment from which we come? High dust desert? High bug zone?
-Is it because we have a dry nose and less need to track by nose?
What other possibility I haven't thought about?
