If evolution really happened, how come we humans still have toenails?

I was just wondering.





And no, please don't compare them to the appendix.





It's a common mistake to say that the appendix is a useless organ. It is not. It's a functioning part of our immune system.


.If evolution really happened, how come we humans still have toenails?
It's a vestigial appendage, like the appendix, wisdom teeth, and the tailbone.





It's a common creationist mistake to say that vestigial means ';useless';.If evolution really happened, how come we humans still have toenails?
why wouldn't we still have toenails?





Also the appendix is not a useless organ but it is a vestigial organ. It used to be part of the digestive system. Some species of old world monkey still have a fully functional appendix, it digests plant matter that our genus no longer ingests and so no longer needs to digest. The appendix hasn't disappeared but when it became nonessential, and you can't deny that function or no function the appendix is nonessential, it became subject to mutations that eliminated its functionality as a digestive organ. Over time it started incorporating and expressing immune system related genes thus giving the appendix a new function unrelated to its original function.





So it is a common mistake for people to say that the appendix is a useless organ. It's also a common mistake for people to mistake the fact that the appendix is not completely useless to mean that the appendix is not vestigial. The appendix has a function, it doesn't function well in its new function and it is not essential that it be there performing its new function but it has one. The thing that makes it vestigial is that its new function is not the function it originally evolved for. The appendix beautifully showcases the indirect evolution of irreducibly complex systems.
Parts of the body do not instantly disappear when there is no longer a selective pressure to keep them. Besides, would you have sex with someone with no toenails? If you answered no, then there IS selective pressure to keep them.


Toenails may not serve a function these days, but since there is no disadvantage to having them, there's really no reason to get rid of them. Remember, we are a very young species, only about 100,000 years.
teh skin under there is very soft, and they protect it from damage, but, as you knwo we only have small nails, claws are bigger , thicker, sharper, our nails have evoleved to what they are now, and in the future they may well evolve to soemthign else, or to nothing, the simple truth is we have them because we do





they DO however have a function, ie scraping of parasites, dirt, and scratching





we evolve through a long long process of years


the things change, but only because we breed the change, not becuse evolution 'decided' we need the change





teh change if there is going to be one, which is liekly, will come, but it will be in along time





the appendix is not ';useless'; its just that in US in OUR body, it has become useless


our ancestors used to eat things like leaves, think tough leaves, and we dont





it helps the guts flora, which is part of our immune defenses, but, its not necesary and we could and do live without it, because we eat different foods, and because we bred that change with our partners





in teh horse the appendix is very useful and their appendix is actualyl about the length of their body
Jennifer,





I don't understand your question. What makes you think that evolution would preclude the existence of toenails?





Toenails exist for the same reason that any of our other organs exist.... they aid us in health and survival. Toenails protect your toes from damage, especially against objects in front of you hitting your toes when you walk. Bipedal animals with toenails are able to keep their toes and feet healthier for longer, making them more mobile and better able to avoid predators. It makes perfect sense for animals who walk on two feet to evolve toenails.
I don't know, but I wish they had because they are a pain to cut every month.





PS - Have you heard that 'more evolved' humans have one less joint in their little toe? Apparently that's something that has 'evolved' in the past few generations, but I can't for the life of me remember where I heard that. And maybe someone was just messing with me ... lol

When was the last time you dropped something on your foot? Were you happy you had toenails then. They help protect your toes.





Dermatologist Mitch Bender appears to agree: ';People can get along without nails -- toenails more than fingernails -- but they do make daily life a bit easier.';
Why would they need to disappear, dear? The appendix has reason to disappear because it makes room for other organs. Literally the other organs will push it out of existence.





You Christians are weird.
The appendix is useless. We can live without it.





Just like men have mammary glands. But we don't have milk shooting out our nips.





I don't know why we have toenails...why wouldn't we? Why do we have eye lashes and brows?
The toenails still help protect outside things from entering the feet, since the skin around them isn't as thick as the rest of the foot and the bones are closer to the skin.
We also have a tailbone.


The fact that remnants of parts that have become useless over time are still there, proves evolution.
Without toenails your toes splay out and impair movement. They support and protect your toes.
Very interesting. I am a creationest so I shall be watching this question for answers. Thank you for the question.
There is no selection pressure to make them disappear.
Or why do we still have tails? I dunno'.
how come we humans still have toenails?


--they support our feet and balance.





I don't see how this disproves evolution.
If I didn't have toenails, then how would I scratch the bottom of my feet, or the backs of my legs?
so we can scratch our itches, and pick at scabs.
