Finger nails - Why do humans still have them?

I'll admit, scratching that itch wouldn't be as easy.. but then, if we didn't still have nails, we wouldn't even know that.Finger nails - Why do humans still have them?
A number of theories about the reasons for having toe and fingernails abound. Most relate to human evolution, suggesting that they are related to the claws which other members of the animal kingdom have. Fingernails especially are highly useful to perform daily tasks, and toenails sometimes come in handy as well, depending on the situation. While toe and fingernails may be vestigial remains of our wild past, most people who have lost nails agree that they are much more valuable than they look.





One theory about fingernails and toenails suggests that they are designed to protect the delicate nail bed. This supposition has been dismissed by many doctors, who point out that people who permanently lose nails develop tougher nail beds. It seems more likely that the delicate tissue or quick under the nail evolved in response to the presence of fingernails, rather than the other way around.





The more likely reason for the presence of fingernails and toenails is that they are useful. Fingernails help humans to scratch things, peel fruit, open things, pick away the outer layers of other edibles, undo knots, and perform a variety of other tasks. In a more distant past, fingernails probably assisted humans with the capture of body lice, as is still seen among the great apes. When the feet were used more like hands, toenails served a similar function, helping humans to open vital food objects, strip bark to build structures, and other such things.





Fingernails help the hands to grip things and start rips and tears. If you remain unconvinced of the usefulness of fingernails, try trimming them to the quick or covering them in tape for a day. Having fingernails out of commission makes it much more difficult to scratch itches, clean the hair and scalp, open foods, and perform a wide variety of delicate manipulations with the hands. Toenails may not be quite as useful, but when you imagine the feet as hands, their presence makes much more sense.Finger nails - Why do humans still have them?

';still have them....';





Because that's how we were made!





No evolution,... nothing has evolved, we still have fingernails!





great question!
we have them because thousands of years back they were claws, and eventually they grew to be more brittle and small.

I learned in my A %26amp; P class that there are three functions of nails.





And they are:


grasping objects,


scratching,


and


protecting the end of the finger (or toe)
we were born with them
Finger Nails are an evolutionary characteristic that humans have never evolved away from because they keep us grounded in our primal and sadistic roots.


They are most commonly used for decoration and attracting mates. When the nail plates are decorated and the lunulas are extended and cleaned, a very promising match can be made.


However, in most settings, the nails are used as a last ditch effort of self-preservation.


I don't know how many times I have been in a deadly situation, only to have my face raked by some crazy chick that thought I was attacking her.


Finger Nails can be a life saver, as well as a life ender.
It enables us to use our fingers in well in dexterous activities, like doing up our shoelaces for example. It's the same reason why all the other primates have them.
