as you are aware, under our fingernails are thin, sensitive membranes called cuticles, and nails protect these. also, back in prehistoric times, humans had to survive in the wild, and the nails protected their hands and feet as they were running through the forests.
[The above answer is ridiculous. Cuticles are a portion of the structure of the nails, the "sensitive membrane" parts of toe nails are simply the vascular parts of the structures that grow and nourish the nail. To suggest that nails exist to protect the sensitive membranes gets cause and effect backward. The above answer also conflates toe nails and fingernails, as toe nails do little to protect the hands. Finally, to suggest that toe nails protect the feet as prehistoric humans were running through the forests, the answerer seems to be unaware of the simple fact that toe nails are on the top of the toes, and even prehistoric humans ran on the lower surface of the toes. You can run in forests just fine without toe nails.]
We have toe nails to as our evolved version of claws, as our biological ancestors were climbing creatures.

Well it depends on what you deine as thick toenails, try cutting them, or go ahead and see a doctor, sometime they may give you something to rub on them that may help them get weaker and thinner.
Regularly trim toenails straight across, avoid cutting them too short, wear properly fitting shoes, keep feet clean and dry, and moisturize regularly to prevent thickening of toenails. If thick toenails persist, consult a healthcare professional for further evaluation and treatment options.
Toenails are composed of a protein called keratin, which is also found in hair and skin. The keratin in toenails is densely packed and arranged in layers, providing strength and rigidity. Additionally, the nail bed underneath the toenail provides a supportive structure, contributing to its thickness and durability. Proper nutrition and overall health also play a role in maintaining strong and thick toenails.
I have a thick toenail too due to losing the nail as a child from being crush in car seat..when it grew back it was extremely thick and hard to cut..its a normal nail regrowth
Toenails help you balnce.
All birds have claws - the equivalent of toenails
get your parents to cut your toenails for you, if you are bad at cutting them.
People eat their toenails because they insecure about themselves!
Toenails float because of low amount of density
My dog's toenails are not black. They are white. Not all dogs have black toenails. Not sure what made you think that but..........you are mistaken.
