What’s the purpose of the little toe? What about armpit hair? Why do we have finger nails? Do eyelashes actually “do” anything? If you’re anything like me, these are the sorts of questions that you’ve been meaning to find answers to, but never seem to get around to it. Today, with the help of Yahoo! Answers, I set out to find some answers.
First up, the little toe. Some folks believe that, eventually, the little toe will go away because it’s no longer needed. Others would disagree and state that it plays a pretty important role in keeping people balanced. But if that’s the case, why are little toes so small?
Is armpit hair supposed to keep us warm? I consulted Yahoo! Answers and found a variety of theories. Some say it helps absorb sweat. Another responder writes that armpit hair helped people identify each other through scent back in the day. And another community member writes that underarm hair helps keep skin from getting irritated. Any other ideas?
Now, on to the fingernails. Calimecita writes that fingernails “offer protection to the finger while at the same time enabling manipulation of objects with our fingertips.” If you think about it, all mammals have some sort of nails. Some are called claws and some are called hooves, but they all serve the same basic purpose.
Finally, there are the eyelashes. They look nice, but what do they do? As it turns out, they do quite a lot. Not only do they keep dust and debris out of your eyes, they also help diffuse direct light. And, as one responder notes, they can be “fluttered” to attract the attention of prospective mates. You can read more here.
Of course, many of the above theories are just that… theories. Do you have your own ideas on why we have armpit hair or eyelashes? Are there other questions like these that keep you awake? If so, leave a comment below and maybe we can get ‘em answered.
