Why Do We Have Nails And Toenails

Why Do We Have Nails And Toenails - Fingernails primarily serve as a cover for the top surface of our fingers and offer some degree of protection. Fingernails and toenails on our limbs are quite similar to the claws found in arboreal animals. Primates, including humans, have broad fingertips, and nails help them support those fingers.

The short answer is we have evolved to have nails because they help us pick things up (like food), pick things off (like bugs), and hold tightly onto things. Nails are made of keratin, a protein found in hair, fur, claws and hooves. But unlike claws, nails are wide and flat, shielding the tips of fingers and toes from injury. As well as protecting your delicate digits, fingernails provide a rigid backingto helpyou grab and separate small objects. This article examines the reasons why we have fingernails and toenails and the clues they give us about our overall health. Toenails, like everything about our physiology, are the product of evolution. Most theories tie the emergence of nails over claws to primates particular climbing lifestyle. Much like fingernails, toenails are made of keratin, a protein that forms tough, protective surfaces on the skin and appendages. But why exactly do we have toenails, and what purpose do they serve in our daily lives?
