    The nails are composed largely of keratin, a hardened protein (that is also in skin and hair). As new cells grow in the matrix, the older cells are pushed out, compacted and take on the familiar flattened, hardened form of the fingernail. Fingernails grow faster than toenails.

Early humans who had these type of nails (instead of claws) tended to live long enough to have babies and pass on the fingernails gene to their kids.

    Why do humans not have whiskers?

    Short whiskers are microvibrissae, and they cannot be moved voluntarily. Humans used to have whiskers too (about 800 000 years ago we lost the DNA for whiskers), but have now largely integrated the function performed by whiskers into their brains, specifically into their somatosensory cortex.

    Why don t apes have claws?

    So, why did the ancestors of monkeys, apes and humans lose their grooming claws? One possible answer: because we have each other. "The loss of grooming claws is probably a reflection of more complex social networks and increased social grooming," Boyer said. "You're less reliant on yourself."
